Major WiFi connection issue

Hi
I've had a search in the forums but haven't seen any other posts re. this but wondered if anyone had any ideas?!
Basically I'm having problems connecting to some networks with my Tab 10.1 (stock, updated OTA to the latest TouchWiz UX last week).
I first had a problem last week when I took the device into work - there's an 802.1x EAP network there but it wouldn't even show up in the network list. My SGS2 connects to it without an issue.
Then when I got home tonight (after happily using it at my parents' house during the day) I found it wouldn't connect to my home WiFi (hidden SSID, WPA2). It had connected to this network fine in the past, but now was just sitting showing it as 'not in range' network. At first I thought it might be a router issue (it used to be a little flaky), but then I saw that my iPod and SGS2 were both connecting and working on it without a hitch.
I couldn't see the network at all in WiFi Analyzer (similarly to at work), although it was showing my neighbours' WiFi networks fine. I tried deleting the saved entry and telling the router to broadcast the SSID but it still wouldn't work.
I then put on my WiFi hotspot on my SGS2 (also a previously remembered connection) and it worked absolutely fine!
Does anyone have any ideas where to go next apart from doing a full reset? (which although not the end of the world would be quite a pain).
Thanks for any suggestions/tips!

OK, bit the bullet and restore my device to factory settings - it STILL can't see my home WiFi, despite my SGS2, laptop and iPod all connecting to it fine. It is however showing up two networks belonging to neighbours and also my SGS2 if I put it in WiFi hotspot mode!
Any suggestions folks??

Sounds like a route issue, did you reboot the router? Is the router on a channel below 12?

Hi thanks for the reply!
I actually just spotted a post at http://www.thegalaxytabforum.com/index.php?/topic/5511-my-wifi-no-longer-works/ with the same issue.
It looks like Samsung have mucked something up when they made the Touchwiz UX update - it now blocks WiFi channels 12 upwards, when the old stock Honeycomb firmware didn't do this. I'd moved my router onto 13 to reduce congestion and I guess the work one must be on 12/13 too.
I can see from the table at http://en.wikipedia.org/wiki/List_of_WLAN_channels that 12/13 are only allowed under low-power conditions in the USA, but this isn't the case elsewhere so they shouldn't have locked it down outside of the USA.

This also happend to me

As I had setup an additional router in my house (with assigned a high numbered -or so i thought- fixed IP address) for some reason my main router tryied unseccesfully to assign the same IP to my SGT as the router. This had obviously conflicts and could not log in.
Went into the router eliminated the fixed IP address and voilá! it got working again, all IP a dinamic!!

Wi-Fi connection intermittent failure - requires router reboot!

I've been having this issue with both my Nexus' - my 10 and my 7.
I'll look up and find my connection bars greyed out or none showing and my connection dead. All the other devices on the network will be functioning just fine, just the Nexus will have no connection (I have two laptops - one Mac one PC - several cell phones and sometimes a printer)
Looking at the settings the network will show that it's either trying to connect over and over or just "saved".
Attempts to log back in will be unsuccessful with the device seeming like it's failing to get an IP address our something.
The ONLY way I can get reconnected is to reboot the router itself. Quite a drag...
Google doesn't seem to turn up anything, and forum searches likewise have not been successful
(One problem is there's a lot of 'noise' in results from searching trends like "Wi-Fi", "connection", etc).
Anyone have a clue? It's annoying, especially when it happens somewhere I don't have access to the router (coffee shop etc).
Mostly tho, it seems to happen at home.
I'm running a Belkin N150 router with out-of-the-box settings.
Any help would be greatly appreciated!
Note: the problems don't always show up on both Nexus' simultaneously. Sometimes one will have a connection while the other does not, and sometimes they'll both be disconnected.
Every other device's connection will be fine tho.

i think ur facing ip conflict, new routers should not have such issue but ur nexus devices seams to have such issue.
try this, manually setup ips in ur nexus device (give ips as far from ur normal ips e.g nomal ip 192.168.1.5-6-7 u try 50-51-52
and also give google dns in ur manual settings
8.8.8.8
8.8.4.4
grayed out signals means ur device cant resolve dns (usually cant connect to google)
replay with updates.
P.S: if you have connected to ur router via push button process then also try connecting to it via entering wifi password key.

Thanks, gonna try this. Lately been getting grey bars but still have internet so perhaps it's related to a dns problem.

Download free App from Store - "Wifi Analyzer" to scan your 2.4 Ghz band to see if interference from other nearby routers on the same channel might be causing interference. Switch to a less congested channel might solve the problem, Fios routers tend to default to Auto, usually on 1, 6 or 11 - your signals might be "fighting" with several others routers trying to "hand-shake" between the devices - do it while rebooting the router.
Take a look under Settings - Wi-Fi and then "Advanced" to see what is your N7's setting on "Keep Wi-Fi on during sleep" - if it switched into energy mode/sleep, it might stay there & wake up to resume. This is known to happen to Android devices but iOS ones too.

https://code.google.com/p/android/issues/detail?id=40065
This is a known problem. Read the above for more information.
My solution https://code.google.com/p/android/issues/detail?id=40065#c737
I have a N7 32G and an ASUS RT-N66U and had been having disconnection of my Wifi during use. Sometimes, turning on and off Wifi works but at spots in my house that's a bit further from the router, it will not connect. A few weeks back, rebooting my router helped for a few days and same problem occurred again. Then I tried static IP, and that helped for a few days. The latest test I did was to increase the "Network Key Rotation Interval" on the N66U from the default of 3600 to 7200. Crossing my fingers and hoping that this will finally solve my disconnection problem. My Wifi is set to 2.4GHz band, Wpa2-personal AES.
My firmware https://code.google.com/p/android/issues/detail?id=40065#c743
is firmware is 3.0.0.4.260 which is the latest.
Hope this will be useful for you. :thumbup:

wireless network problem

I have an AT&T galaxy s4 and I've been having trouble with the wireless. I can connect just fine to the netgear router at my apartment in Athens but at home I've been having trouble. At home we have AT&T uverse with an AT&T branded router. My phone will connect for a little while but eventually the small down arrow under the wireless symbol in the status bar starts blinking and the phone says it's connected but I don't have internet. Ive tried searching for a fix but it seems that the only routers people are having trouble with are dkink routers. The problem seems to trigger after I try to load a new site or refresh a page. Also, locking the phone triggers it as well. I've tried changing the security settings, forgetting the network and re-adding it, as well as turning the wireless network power saving option off but nothing works. I've rebooted the phone and the router but it still messes up. What's odd though is that my brothers galaxy s4 connects just fine (although I haven't been able to do extensive testing on his phone). Also, I was home last weekend and the weekend before and it worked just fine. I haven't rooted my phone or changed any settings that would have impacted the wifi since then. Anyone have any ideas?

I'm having very similar problems. When I connect to the wireless, the phone will work on it for about a minute and then stop getting to websites, etc. I have a Motorola SB 6121 cable modem with Vonage and a Dlink DIR-655 wireless modem. Inet provider is Comcast (only option here).
Anyone else having the same symptoms?
I've done the same troubleshooting steps: factory reset, power cycle, default settings, etc and the phone does the same thing.
EDIT: it's been working longer than usual now. I adjusted the Transmission Rate from the Wireless setup to 54 from Auto and the wireless has been stable much longer. See http://forum.xda-developers.com/showthread.php?t=2253471 for people sharing the same pain we have

[Q] Can't Connect to WiFi Network That's Not Broadcasting SSID

I just purchased the Samsung Galaxy S5 and I have a Western Digital My Net N750 Router. I have SSID Broadcast Disabled and the S5 won't connect. If I start broadcasting the SSID it has no problems connecting.
I have over 20 other devices that have no problems connecting with the SSID disabled, so I don't understand why the S5 can't do it. Even my 3 year old Samsung Galaxy Nexus has no problems connecting with SSID disabled.
I called Verizon and they said they haven't heard of this problem before and that the phone is defective and to return it for a replacement but I have a feeling I'll have the same problem with the replacement phone. I've searched Google trying to find people with similar problems but I can't find any other posts. Can you please help me! Thanks so much.

Perhaps so, but if you don't you won't know for sure. You can try to get it working, but if you exchange and it still continues to not work, then Verizon has it on the books that you had a defective device, and they can start working on fixing that silly problem.

I was hoping someone with the same phone can test it to see if they have the same issues. I'm going to do a factory reset right now to see what happens for troubleshooting purposes. That's also what Verizon recommended that I do. Then I'm going to Verizon to exchange it. If someone else with the same phone can test it to see if it works on your phone or not I would greatly appreciate it!! Thanks so much!

I wonder if it's a compatibility issue with my router. Maybe I should go try it on someone elses router and not broadcast their SSID and see what happens. That will help me determine if my phones defective, or if it's a compatibility issue, etc.
I'll still do a factory reset and replace the phone if I still have problems to see what those results are too. It would also be helpful if people with the same phone tested it out to see what their results are. Thanks!

Thanks for the information. To help me trouble shoot it did you connect 2.4Ghz or 5Ghz? What's the make & model of your router? I'm trying to figure out if my phone is defective or it'a a compatibility issue with my router. I'm trying to connect 5Ghz so maybe I'll try 2.4Ghz now. I'll also try connecting with someone else's router. Thanks!

Try adding the network manually

I had this same issue. It would happen if I had the SSID broadcasting, connected my S5, then turned off the broadcast on the router. It wouldn't work if the phone had found the network through a scan. I got mine to work (with my Netgear R6250) by adding wireless network manually on the phone. Hope this helps you, too.

Any resolution on this? I have the same issue. Since I'm rooted and happy, I really don't want to return my phone.

I am aware this reply is over a year later but I am assuming that there may be others this issue is happening to.
I also had the identical problem. When SSID was set to broadcast, the One Plus and Samsung Galaxy S5 would connect without any issues as normal. When the SSID was set not to broadcast, I would have an authentication error and/or show the WiFi connection saved. All this started after the router's f/w and both phones' (Android)OS were updated. This was on both the 2.4GHz and 5GHz frequencies.
Here's the solution - this is done on the phones/mobile units having the connection issues AND having your router's SSID's set not to broadcast.
1) Hold and press the WiFi connection and select "Forget"
You will now more than likely see those available. Make sure you don't use these connections
2) You now have to chose the option to "Add Network" from the menu (One Plus) or "Add Wifi Network" at the bottom of the WiFi settings on the Galaxy S5.
3) Manually type in the SSID you want to connect to, select the type of security and enter the password for your WiFi
4) Repeat steps 2) and 3) if you have a second SSID you want to connect to
5) You should be able to now connect to your Wifi network, if not reboot your phone/mobile device and you should now be able to connect.
Hope this helps you out.

S8 Internet connection may not be available issue

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.
https://youtu.be/Nu5FjDPLn-M

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
