I have a ZyXEL P-2602HW-D1A Wireless router. I have tried all combinations of security, even NO SECURITY WHATSOEVER, and still the device won't transfer data.
Not working;
Firmware: 1.5, Build: CR817
Wifi Router: ZyXEL P-2602HW-D1A
Security: Tried All; WPA2, WPA, WEP & None.
Problem: Connect under all conditions but no data is sent
Please help.
Have you tried another WiFi access point to check the devices WiFi module actually functions?
No, I haven't tried that yet, but don't really see the point... I've connected effortlessly to the same WiFi network with my HTC Touch Diamond.

For some reason my N800 wouldn't connect to MY ZyXEL P-2602HW-D1A unless I set the device (N800) to disable any kind of wifi powersaving features it had.
On another note, how did you get your hands on the device so early? I'm guessing you are using a Cybercity internet connection? (I'm in copenhagen myself)
edit: I actually came to that solution when i noticed I could connect to OTHER accespoints, but not the Zyxel ones.
Same problem here in France with a Freebox as router
I've noticed under the router's WLAN client list that the device does not have a "Host Name". Would that present a problem?
It is assigned an IP address by the router without any problems, though.
Also the device seems to lose connection and reconnect constantly (every 5-10 seconds).
I done some digging around in the router settings and found an "AnyIP" feature. Would that possibly help?
There are a number of issues floating around. Support for WPA2 seems iffy and some people can just change to WPA or WEP and all work fine.
There are however a number of people (such as me) who can get a connection perfectly, it shows connection OK, they get an IP from the DHCP server etc, they can even browse a page for a few seconds... but after that no data is sent and everything times out. This is happening on any security from none through to WPA2.
I have seen no solution to this anywhere and believe me I have looked. Some people have given up and got a new router, but this is not a solution.
Can someone confirm that this has been recognised as a fault with the magic and is being investigated, rather then assuming it's a user or router error. There are far too many instances of this across many brands of router for it not to be an issue with the HTC Magic.

What I mean is have you tested the device on ANY other AP except the ZyXEL?
No, but since I'm by far the only one having this issue (try searching the web; see my last post), I didn't feel it was necessary. Just want some input from xda-dev that might solve the problem, if any.

I've had exactly the same problem earlier with the N800 on the zyxel. Exactly how you describe it.
Did you find out if you could turn off any powersaving features on the HTC?
same problem here
in france with a freebox
I don't exaclty know what router is in the box
but I have excalty the same
I set on never the wifi sleep(powersaving) mode.
i found it in setting wifi menu button then advanced and "never"
but the problem is still here

I have the exact same problem on mine. I just hope it is not a hardware issue...
Could be DHCP lease time problem. Did anyone of you tried to set up Magic with Static IP?
Yes, I tried that also - didn't help one bit.

I also have this problem. Im in Denmark with a Zyxel P660HW-p1.
Another user of Cybercity in Denmark with the same problem.
ZyXEL P-660HW-D1
The android is the only device that doesn't work. I have tried with Iphone and laptops.
I've tried to change the settings on the router to no avail.
Enable 802.11g+ mode [on/off]
RTS/CTS Threshold [2432/4096]
RTS/CTS Threshold [2432/4096]
Max. Frame Burst [600/1800]
The device shows up in the device list with no hostname, the HTC Magic gets the right ip address (using the program WhatIsMyIp to view it)
I had the same problem before, when I set my TP-LINK draft N router with WEP security my HD can see it, connect to it (but speed was slow tho), and my HTC Magic just keep saying its not in range. However, when I set it to open security it works, so I recognise its probably the security setting... so I changed that to WPA2 and then it works.
In my case, I see different device have different tolerance to some settings (in my case, draft N + WEP is OK with laptop, HTC HD, but not Magic), so its still worthwhile to try a few different settings, and try a public wireless access point also to double confirm?
Power save?
I have Zyxel (P-2602R-D1A) router.
I had exactly the same problem with my HTC Vox (winmo)... but that was solved by boosting the WiFi in the phone.
WiFi -> Best performance
So Im guessing magic is in some WiFi "power save" mode...
I dont know how this works, but I thought maybe you could change some WiFi settings behind the hood - that is if the hardware is capable of it.
Zyxel (P-2602R-D1A) router
I am having the same issue with this router as the other posters. The phone connects perfectly and reports an excellent signal, but barely sends or receives any data. I have used a terminal emulator to ping the router and it reports an 82% packet loss. This must be a big problem for many Danish users as it is the standard wifi router provided by two of the major ISP's.
same issue here with my vodafone uk magic.
wifi connects and i can browse for a few seconds then get a connection error and can't browse until i re-start wifi on the magic...
i've actually given up using wifi at home now due to this.
router is a talktalk supplied Huawei Echolife HG520b using 128 bit WEP
i can connect fine via wifi at the office so i don't think it's an issue with the handset, just with certain routers or router configs...
this issue has been reported on the vodafone uk forums but as yet no solution.

Hello all,
I love my X10, but the frustration with getting it to connect to my Netgear DG834 router was getting to me, so I dedicated an afternoon to working out a solution and I've found one that works for me, so I hope it'll work for you too.
Summary of problem
--------------------
The phone will connect to the Router once, and once only. Any attempt to re-connect to the wifi will result in the phone disconnecting, scanning again, then discinnecting until the user gives up. Nothing will cause the phone to reconnect (telling it to forget the connection for example). The only surefire way to reconnect is to reboot the router each time - not ideal.
Manually adding a Static IP also doesn't work - which is weird as that is how I've solved it, see below.
Scale of problem
----------------
The problem seems to be with the router and not necessarily the phone as it appears to be on a wide range of phones (Hero, Droid, Touch HD etc.). Seeing at the DG834 is the most popular router in the world, and Android is growing all the time, there are a large number of people affected.
However Iphone and Symbian phones appear to be unaffected.
Reason for the problem
-----------------------
Currently unknown, but appears to be something to do with the handshaking procedure when a device asks the router for an address (DHCP) - though as to what I don't know.
Solution
--------
1) Download an app called WiFiStatic from the App Market. WiFiStatic takes each DHCP assigned IP address and stores it in a small database to be re-applied whenever you are back in range of the same Router again. It is not an ideal solution as you may have to re-scan and re-assign if you visit a busy hotspot, but this is a two press function, so it's not that onerous.
2) Turn off your Router. Make sure the WiFi on your phone is off too.
3) With the router off, clear your Remembered WiFi connections (or at the very least the Netgear connection). Once that's done, turn the Router on again and wait until it is full back up again.
4) When the Router is fully operational again, turn on your wifi on the phone and let is scan for and connect to the Netgear Router. You may need to tell it to connect from the Wireless Settings menu on the phone.
5) The phone should now connect to the Router successfully. If it doesn't, repeat the above procedure.
6) With the phone connected to the router, fire up WiFiStatic. Check Auto Switch and Show Visual Prompt if they are not already selected, then Tap Add configuration at the bottom of the screen.
7) The IP address and other settings assigned by your router should be displayed at the top of the screen, at the bottom should be the name of your router and its MAC address. If not then tap Menu > Generate to populate the form.
8)Tap Menu > Done when everything is ok.
That's it. Now when you move into range of your Netgear, you should get connected, though it does take a bit longer than normal (the Router still wants to assign an address first before accepting the static IP). You can speed this up by changing the Device table on the router to always keep the Phone's static IP open.
This shouldn't work as all my other attempts with Static IP failed, but I've had five days now of instant connection to WiFi at home, so something has been freed up.
i can not tell you how seeing this post was like finding bin ladin in the white house. Prob would have found him twice trying to solve this WIFI problem. And the strange thing is this is the 1st phone i have had that there are so few posts about it...is everyone on that icrack? scary. cheers to you...
Thank you for posting this.
I tried this with my and it seems it doesn't make a difference for me. I still can only connect once to the router and for me to connect again i have to restart the router again. Am i missing something?
Problem is when I connect for the first time at home it works then when i leave to the office i use the wifi there and never have any problems there but when i get back home it doesn't work. Do you guys switch the wifi off manually when you are not using it?
one thing that is almost always overlooked is updating the router's firmware. this usually solves a number of issues. I dont know about netgear but it's worth a try to update

That was one of the first thing i tried....it seems i have the latest firmware.
Is this an issue for a lot of people then? Ive one of these routers and never had an issue connecting any phones to it. Had 3 nokias and 3 different android phones, currently on the x10, and they all connected fine everytime.
i have some troubles in x10i wifi connection and holp someone helps me~
------------------------------
im chinese, my x10i have had the lastest firmware but the phone cant connect the AP which set the channel is "13". but i used it long before and suddy just one day i find it dosnt work~ it cant scan(and find) the AP anymore !
then i have tried and config the router in another wifi channel(just like 1,8,11..) and the phone can scan and refind the AP.
i have tried to reload the phone's default setting,but it dont work(in channel 13)ToT
---------------------------
someone tell me why? and someone give me some suggest?
in china , lots of router's wifi channel are using "13" by default(factory setting);so, if my x10i cant works in that channel means i couldnt find the "opend APs" which in the public place(like KFC~~)
THX to help~

Thank you! I have spent three days trying to get my phone to re-connect to a DG834v5.
Your solution has worked! I had gone as far as reserving an IP address on the router and linked it to the MAC of the phone... no dice. The phone would connect once and then never again until the router was reset. Really irritating because I have two PPPoe connections running through the router with a routing table that has to be re-loaded via telnet every time the router is reset. I was considering a new phone or a new router.
HI,
I have near the same problem.
But I found out that when I remove on the access point the hidden function ( SID ) then it works perfect.
so that is a bug in the ROM of the X10, I have the R2b026.
At the moment everone can see my Access Point but I can live with that solution.
Worked for me! Many many thanks this had been infuriating me...
Same problem here - never had an issue with any other router, so I blame Netgear...
Let's just hope this works - it's been driving me crazy for the past 5 days...
Neh, hasn't worked for me....
Stupid freakin' Netgear...
works on the HD2 aswell. Thanks alot!
Not just Netgear, maybe Android

I am having the same issue on my HD2 Android 2.3.4, connecting to a D-Link DIR-635. If I use Static IP, everything is fine...
WORKS! I can't believe it, finally i can disconnect and connect without having to reset my router everytime. BIG thanks man!
alright, it worked fine for the first 5-6 hours. then it went back to not connecting without rebooting the router. this problem happens only with my home router, at work i can connect fine, as well as in other places.
any thoughts or solutions? i mean it did work in the beginning, then why did it stop? shall i change my router?
P.S.: i noticed that every time i connect to my home router i get the same IP address and all the stats are the same.
My Wifi connected to my home router perfectly until I flashed the custom rom.
Now it wont work. the phone recognizes my network, then tries to connect but it pauses at the obtaining ip address bit and doesn't connect?
I tried to restart the router. It doesn't work.
I tried to reflash the rom or offical rom (KE7). It doesn't work.
I also tried to delete the file /data/misc/dhcp/dhcp_list, but there are no "dhcp_list" file inside 'dhcp'
Do anyone have another way to solve this problem?
Thanks
Could be a problem with the router, are other devices able to acquire IP addresses from it correctly?
Perhaps you should assign a static IP to see if that makes a difference.
I am on KE7 stock rom with root and had this problem too. It just started yesterday and got stuck at obtaining ip adress. So I switched WIFI off and flight mode on and after some seconds wifi on and flight mode off and it connected. I also noticed that now sometimes when it is in standby it disconnects from the wifi network (but wifi is still ON) and when I wake it up it connects to my network.
Me too, same problem.
If wifi is ruled on "sleep when screen turn off", it don't wake when screen turn on.
It stay on " searching for IP adress...".
For the moment, I'm forced to leave wifi on "never" and I use Juice defender for disabling wifi on screen off.
I really think it's a common pb with SGS 2. May be it will be fixed with 2.3.4.
Same problem. I 'fix' it by turning off wifi then turning it back on and it gets an IP address immediately.
same problem here with a dlink dir-615 router. from time to time the phone can't get an ip, and it only works if i reboot the router. didn't try with another router yet ( well, i connected to a few more but not frequent so i can see if there are problems), but i ordered a new one anyways since the dlink also crushes my battery too.
try posting the brand/model of the router you have problems with, maybe there's some specific ones that are troublesome.
d-link dir-615 here / ke7 stock - rooted
I also have a dlink router. But I get the same problem with a Belkin.
With my first SGS, no problem. I really think it's a specific issue on SGS2.
I'd read in some place that 2.3.4 will fix some wifi problem known for the moment on 2.3.3...
Let's see...
I'm seeing this with both my home router (Netgear WNDR3700) and my office router. Disabling & re-enabling WiFi on the SGS2 solves it -- fortunately, it's easily accessible on the notifications panel.
Same thing with Dlink dir 815.

Same thing here with Draytek 2820 router, all other devices (PC's Phones, PDA's etc) have no problem. SGS2 however needs WiFi turning off when waking from sleep to get it to obtain an IP address again. However my HD2 also running Gingerbread 2.3.3 works faultlessly.
KF2 seems, for me and some others, fix the problem...
hi
lucky me, i thought im the only 1 having problem with wifi
my problem, same as the others
the wifi try to connect (obtaining IP) and then disconnected
it will scan again, same thing will happened
try with all type of protocols, wifi b,g,n wep, wpa, no passwd
results still same
try to connect wifi at my office, results also the same
im on KF1 using dlink 615
hopefully someone can help us
tq
Just got my Galaxy S2 today. Cannot connect to wifi network on G or mixed mode, with or without security - just tries to obtain an IP address. Ridiculous.
Any help ? Quick search on Google doesn't bring up too much. There does seem to be an app called "FXR Wifi" but I don't expect to use that on a brand new phone.
Update: Upgraded my router's firmware (WRT54GS) and it works !
I have the same problem with my SGS 2. I can't connect to an AP - NETGEAR DG834G.
I found a partial solution to use my phone with my AP until I solve the problem. In the Wi-Fi settings menu enter Advanced mod and set the IP address, Gateway, Netmask, DNS1 manualy (by touching <Use static IP>). If you don't know what IPs you have to set for IP address, Gateway, etc. just connect with you laptop or desktop and use the settings from your computer. Just make sure you type a different IP address in your mobile (not the one from your computer - for example in you computer you'll find something like this: 192.168.0.3, you'll have to type in your mobile something like this: 192.168.0.10). The rest of the settings have to be identical.
Good luck!
To solve this "obtaining ip address problem". Set the following manually in the advanced configuration and save it.
1. ip address(your choice).
2. subnet mask(255.255.255.0).
3. default gateway(192.168.1.1).
4. dns servers(8.8.8.8,8.8.4.4)
Note: The above given values are the most commonly used, you change it if you want so.
After entering these values manually(and correctly), it will connect to the networ in 1 or 2 seconds.
like mine SG s2, wifi connects works perfectly at home and friends place,
but stucks at obtaining ipaddress for wifi, at the mall and college, ( where it needs first login page for authentication) ( or to agree user terms and regulation),
any idea, how to fix this issue.
Thanks
mine also does this where it doesn't get an ip. Reboot your router or just disable and re-enable the access point feature on the router and it should work without having to reboot it

Hey guys! Did you find a fix for this problem? I have the same thing happening right now. I tried at different places, home and country house with Zyxel P660HN and Cisco E4200 respectively. Stuck at obtaining IP address...

Honestly I have no idea why this is happening on my android 4.0+ devices. I will get stuck on obtaining IP address connecting to certain networks and the only thing that worked for my home network is static IP. But for instances when I don't have access to the router to know what the static IP should be, is there a way to get this working? This happened on my phone as well. I was at a local cafe which had wifi and before I upgraded my samsung galaxy s2 to ICS, I could connect to their wifi no problem, now it has the same issue, and so does my Nexus 7. I don't know what to enter for static IP, I entered some random IP, it connected but internet still didn't work. Why is this problem plaguing ICS onward, and does anyone have a workaround when static IP is not an option?
This is definitely not a universal problem (I've never heard of it before). Are you running stock roms? If not, then do you have these problems with stock roms?
C2Q
Why are you posting this to multiple threads?
There is no "proper way" to use a static IP for a router that is setup for DHCP only. For routers that use both, many times the static IP's are reserved for specific devices.
Sent from my Nexus 7
Because I didn't notice the other thread before I posted this one. Anyway then why is this obtaining IP address loop a problem on ICS? As I said, my phone on GB would manage to connect/obtain an IP address just fine before I upgraded to ICS. This happened with my home router and other areas as well. The solution that worked for me at home was to assign a random static IP within my routers IP range. But if I don't know the gateway IP this won't work. So what gives? I'm kind of confused what you mean by routers set up for DCHP only. If I use static or DCHP options on the android device to connect, they will both work (this was before ICS).
I ran into similar issues with my nexus 7 and my work open wifi. It needs you to connect to a web login page where you accept a use policy before you can surf. My nexus would connect but never redirect to that login page.
The issue was resolved by using static IP instead of DHCP and also by changing the DNS values to DNS1 8.8.8.8 and DNS2 4.4.8.8
Changing those settings lets me finally use my work wifi. My phone also has the same issue (its an ICS phone, whilst the nexus is jelly bean) but is not resolved with this change.

Sure that is not 8.8.4.4 ?
Thanks for posting this question. I have exactly the same problem with my Samsung S3 (ICS) and Nexus 7 (Jellybean). My old Samsung S2 (Gingerbread) worked fine.
I am trying to connect to a hotel open network. When I try I get the looping "Obtaining IP..." message. I have a strong network signal.
What gives? How come earlier versions of Android worked but later ones don't?
As the OP stated, the static option works insofar as I can then connect to the network but the made up static IP numbers do not actually let me download (or upload) data. As the OP wrote, you need to know some valid values for the static IP setting.
Does anyone have a solution for this (apart from downgrading to Gingerbread)?
Ive always had this issue but my home router has dhcp off. A majority of routers start with 192.168.1.1 or 192.168.1.2 so its not hard to work it out.
BT routers always start with 192.168.1.254 so there's another option dunno why my devices do it but im used to it. My Wifes Xoom 2 and wildfire S are stock and do not have the issues my rooted ones do but i have just put it down to coincidence
First off. Is your modem in service? Do other devices connect? Have your restarted your tab? Does it connect to other networks? Meaning going to another WiFi hotspot If you can answer yes to all of these questions we move on....
What modem/router are you connecting to?
What type of WiFi encryption are you using? Wep-open, WPA, wpa2-psk
On the tab does it fail to obtain the IP address? Meaning it says "remembered"?
Not going to lie more the 3/4ths of the time you have the wrong WIFI PASSWORD. CHECK IT AGAIN usually its on the modem/router or if you have no clue here is a hint: on windows vista and windows 7 under control panel>network and sharing center>manage WiFi networks if your right click on the network name such as "Ilovepancakes"and go to properties it will have a security tab that you can click on and show password.

I don't know what you mean. Do you mean that I should try these numbers to see if they work? You need a number of values to set up static IP addressing to work.
Did you dirty-flash your Nexus? A while back my Gnex wifi connections would take longer to complete the handshake. I did a factory reset/fresh install & it has been much faster.

My Nexus (and GS3) is completely stock (I have only added a launcher).
This problem seems to be caused by older routers, which don't seem to like something about newer versions of Android.
I'm not sure if it's something Google can fix, but the combination of old router and new Android seems to make logging onto wi-fi networks a problem.
Bump.
Ive been struggling with this problem for a week now since getting a transformer infinity. My s3 gets stuck when I try to connect to it. The tab cycles through connecting, obtain a valid address and saved.
I bought a new 32gb nexus yday and had this issue. I entered advanced settings, changed dhcp to static. Changed IP addy to 192.168.1.1 and it worked fine. Only had to do it once. After that it connected to every network fine without changing settings again.

This worked for me also (Infuse 4G on JB), but it seems like this is only a problem on WiFi AP's that have marginal signal strength, even though they appear to have full bars. I personally have never have seen this issue on a network that was performing properly.
Same here!
Same thing is happening to me! Im using he htc desire c running ics.. my phone detects the wifi network, shows that it has excellent strength, but it gets stuck at "Obtaining IP Address"! My friend and I both bought the same model a couple of weeks earlier and till now neither of us have been able to connect to a wifi network! Please Help!!!
its a DHCP bug
This is probably not a problem with your network configuration unless it works everywhere else; im having the same problem as well as other people i know and its definitely a bug with DHCP, so the only way to work around this is by using a static ip as far as i know

What he's saying is that most routers will begin assigning addresses starting with 192.168.1.1 or 192.168.2.1 for itself (you can access the router configuration page by typing in this address into a web browser), and then increment upwards afterwards. If you knew that the router started its DHCP addressing with 192.168.1.1, for example, you could try 192.168.1.2, and so on and soforth.
If you did a "dirty" upgrade, I'd recommend doing a factory wipe (after an appropriate backup-- there are some good apps out there that can handle this). In-place OS upgrades have a bad habit of being finicky. Android is also generally less tolerant of network "misconfigurations" than, say, Windows, OS X, or iOS. Many networks that use captive portals (your standard coffeeshop Wi-Fi) deliberately use an altered network setup to support their access policies, such as a captive portal.
However, with the exception of corporate/enterprise networks (which may require fine-tuning because of increased security), you really shouldn't be messing around with this if you don't have at least a rudimentary understanding of how networking works. That's not meant to be insulting, but when people plug in random values and find it doesn't work, it tends to lead to more frustration than utility.
(fyi: The reason you can "connect" by tossing in a random set of octets your your IP and DNS is because you've properly authenticated against your router, but you'll never be able to receive data unless your router's DHCP lease lines up with your self-assigned IP, because the router never handed that address out to you. It's the digital equivalent of building a mailbox in front of your house without registering with the post office, and wondering why you never get mail).
Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I had this problem when i first got my s8 from vodafone but when i got this latest update it's been good no issues with internet anymore.
I have this problem as well with my S8 from Verizon. Worked flawlessly for a week and them today I get this error. Very frustrating. I know the SMG955U from Verizon is already unlocked but is there any way to put the International ROM on the phone seeing that the Verizon and the International are the same?
I've tried all the resets etc and the WiFi connects but I get the 'Internet connection may not be available' message.
Update 27/04/2017
Thanks for the reply. My S8 developed some interesting issues including the switching on of 'do not disturb' mode intermittently and along with the Wi-Fi issue the mobile data was failing in areas where a full 4G signal was present. Rebooting, resetting etc did not resolve the issue and I returned the phone to CPW for advice. The staff at the Glasgow store wasted no time and exchanged it on the spot after some negotiation with their technical service centre. Full marks to CPW for the prompt service and I can report that all of the previous issues have now been resolved with the replacement handset. I thought it worthwhile to post this information so that others who experience similar issues may be able to get a similar resolution.
Poor WIFI performance
I also have issues with the wifi of the phone, /i will get the terminal replace some time today or next week.
1. WIFI keeps disconnecting, actually it's flapping connct&disconnect for 5-10 min until it finally connects, on this matter I have seen on the acces point that it tried to allocate an ip from an unknown without asking DHCP server for an IP renew it actually tries to alocate itself the last known ip, and clearly disconnects because of lack of internet access, this happens normally as power saving mode is on, disabeling power saving and assigning a static ip on the phone seems to resolve the issue.
2. poor wifi signal... no fix for this thus far
- i have 580Mbps speed connection on my S5 and only 120-240Mbps on my S8, steaming not working and connection in general very bad, time ots and stuf, although I position myself at 10cm away from the wifi router antenas i only get 540Mbps signal, although I have an AC1750 router , s5 gets 840 in the same spot... I think the modem(that is part of the Exynos chipset) does not work wekll with Atheros based AP´s , I have an Archer C7 with 2.4ghz QCA9558 chipset capable of 450 Mbps theoretical speed, but only uses 2 antenas as s8 only has 2 from my knowledge and reaches a max of 140Mbps(should of connected at 300Mbps at 10cm in theory ) with the s8 and QCA9880-BR4A on the 5ghz side of things with a theoretical speed of 1300Mbps should work at 866 with the S8 because of the 2 antenas of the S8.
phone changed 90% of problems fixed
Hello, just got my phone replaced, tha new unit has way better wifi signal considering I hace atheros router and the phone has broadcom 43xx chipset... worth considerign changing to a broadcom router...
Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect.( It requires to be entered manually) Problem will be solved.

Change the DNS...
Hi there..
I had just the same problem with s8 plus and s7 edge(after updating to android 7.0), it kept saying "internet may not be available", I changed the DNS to 8.8.8.8 and tue problem solved. Go to SETTINGS》WIFI》SSID》MANGE NETWORK》change the IP SETTINGS to STATIC》then change the DNS1 to 8.8.8.8 hit save and you are good to go.
Sorry if there are any mistakes. I am new to XDA and not good in english.

I have same problem and it is very annoying. I got 2 S8 plus and both have the problem.
There are 3 WIFI Router that covers my house. I have problems saying internet might not be available every time I connect. This is very annoying. Other Phones in the house like Iphone do not have the problem.
What I noticed is that the IP range of my router is:
192.168.1.1
But my S8 says he is connected but the IP is
192.168.0.100
Anyone have same problem?
Thanks!

I found a quick work around on how to fix this temporarily until Samsung issues a patch.
just turn off 5ghz SSID broadcasting and you should be ok for now.
here is a quick how to video i made on just in case.

I'm having a very similar problem with my home WiFi and my Verizon S8+ I bought from Samsung's website. I've tried switching from DHCP to static and entering all my info. No luck. I've also switched my dns1 to 8.8.8.8 and dns2 to 8.8.4.4, and my WiFi router is set to 2.4ghz only. No success in resolving the issue. Currently my phone will show the "internet may not be available" with the added exclaimation point for a few minutes when first connected, then the exclaimation goes away and I'll have regular full speed internet for around 25-45 seconds before it goes back to a non-internet state. Any suggestions?
Try changing in your router the security setting. If your using WPA2 AES/TKIP, change to just WPA2 TKIP and see if this works for you...
I was having the same exact issue for months. I changed to TKIP only and have been rock solid ever since. No more ! at all... I'm gonna switch to just AES today and see how that works.
Changed to WPA2-AES and within the hour had ! back and no internet. Went back to TKIP and rock solid again. Looks like a possible bug with AES to me. Sticking with wpa2-tkip setting for now.
I'm having this same exact issue.
Anyone who knows what to look for to fix this, what info or files do you need from me? I'm at the end of my tether with this ****
I am having the exact same issue on my galaxy tab s2, even on the replacement. Due to the being such an intermittent problem, it wouldn't do it when Samsung support checked it out...
This happens on both 2.4 ghz and 5 ghz frequency for me. I've tried downloading a wifi fixer, I've reset network settings, and turned off nearby device scanning. I've also tried doing what a forum suggested by changing the ip settings from dhcp to static but it wouldn't connect to wifi at all. Not sure what else to try...
I read that it may be due to nougat 7.0 software. I was suggested by Samsung to first put the tablet on safe mode (this disables third party apps, and would reveil if an app was causing the problem) but the problem still persists. Also did a hard reset on the first tablet I had but it still done the same problem...
I always thought that this was a is problem in 7.0, and was addressed in 7.1. Hopefully, when the next major update comes out, this issue will be resolved.
Oh come on Samsung!
It's been 4 months since the first post and still no solution.
And it's a basic wifi connection!
Internet may not be available! = Samsung may not be available
Heya all. First post I guess
Edit: Gah it was the second. I have to controll myself better and not spam.
So I had the same problem and tried more or less all.
My "solution" was to disable the firewall on the router which means some settings/security there was triggered. My guess is that it's the "Smart Network connection" that trigger it if the phone have both poor Wi-Fi and 4G. It then jumps back and forward = firewall detect strange behaviour and block. That's why there are so many strange "fix" related to the router - hidden network - no security - disable 5Ghz and so on.
Can someone please test asap as I have a plan But if it's not this to test
