Wifi issues - Galaxy Tab 10.1 General

I have seen a lot of threads about wifi issues but never could find a straight answer. I received my galaxy tab today refurbed from newegg. Anyway, when I try to connect to my home wifi, it is WPA2, the tab says authenticating, but the wifi signal drops and it never connects, then the box pops up again asking for the key. If I use tethering on my phone with no protection it connects just fine. My question is, is there a trick to fox this, my second question is, if I install cm9 on it will that eliminate the problem completely? Thanks

I have heard about problems between the Galaxy 10.1 and specific wifi routers. The case which I followed closely was fixed by flashing new firmware into the router.

have occasionally put my wifi off then on again. then he works well

router
i had this issue. i changed my password, reset router, changed the wifi security to wep, changed the channel . after that, few hours later, to wpa2 and magically back to normal ...this is a router issue.

I changed the decription from aes to tkip on my router to exclude dropouts and have faster mbps

For what it's worth, I have this exact same issue on my Galaxy Ace.

hero wifi dropping out

Is anyone else having issues with the WiFi stalling and having to reset it, even though signal strength shows as excellent?
It's not a channel interference issue as I know what channels are in use, plus its doing the same on 3 different networks where other devices work fine, I'm using WiFi fixer to reconnect but its still problematic.
What have others found to be the best solution?
Samme issue here. Wifi keeps on disconnecting/loosing the connection and is most of the time unable to reconnect. Have to either turn wifi off/on or choose "forget" and reconfigure the AP my Hero in order to get it to work again.
It´s a Linksys WRT54GX running WPA/WPA2 + TKIP.
Have used an iPhone 3G on the same router for a year now without ´any´ problems.
I'm using WiFi quite often but I don't have this problem with my Hero.
Are you absolutely sure that there isn't any interference? It might be that the Hero is just a bit more sensitive than your iphone.
Today I found G-mon at Market which scans around for WiFi-networks. Perhaps you'll find out that there is a network that's interfering constantly. I've had that a few years ago and then found out that the bus-company uses WiFi on their busses which uses the same channel as I did with my WiFi-network.
Thx for the tip. Checked and no interference.
Also having this problem with a Linksys WRT54G. No WPA though.
I don't trust this router at all; using WPA and connecting a Dell Axim X51v to it in the past used to knock out WLAN on router, needing a hard reset.
same problem here. Wifi is disconnecting randomly within a few meters from the Airport extreme. It also reconnects again...most of the time....without me doing anything.
i'm also having problems with wifi - using a linksys befw11s4 with wep. i've got everythign else turned off - have followed all the instructions i can find here in the forums, and not had any success :/
If you press the Menu button in the Wifi settings you can select Advanced. There's an option there that defines when Wifi is disconnected. If you set this to Never than the Wifi connection will be stable. (At least in my case it is).
Again, thx for the tip but this is not really considered a "solution" but rather a workaround.
I don't like the idea of having it on "allways on". A real battery drainer and it shouldn't be necessary.
I had similar issues with my wifi (Linksys WRT160NL) until I installed "Wifi Fixer" from the market on my hero. Since then wifi runs without problems!
I had similar problem, Linksys WRT54G v1.0 running fairly old (but latest available) Linksys firmware, with WPA/PSK.
Yesterday, re-flashed router to Tomato (based on HyperWRT), setup for WPA2/PSK(AES) and now all is working perfectly, no problems at all.
So looks like some incompatibility between the Hero and the Linksys firmware, for WPA.
Well, I'm running the latest firmware for my router but have now done some other configuration changes and it seem somewhat consistent with your findings.
Previously it was running in a "WPA, WPA2 + TKIP" mode but it has now been working flawlessly since I change it to "WPA2 + AES". Hence:
- WPA2
- AES
=
- WPA, WPA2
- TKIP
=
Info, update on the router: I'm having a WRT54GX, not WRT54G.
interesting; I had no choice but to upgrade, as the newest firmware for the v1.0 WRT54G doesn't - I believe - support WPA2.
Since I had many other wireless clients working fine with WPA (not WPA2), but not the Hero, one wonders if there are some WPA bugs on the Hero that get tickled by older routers, or just that the Hero is being less lenient than other clients.
glad yours is better too, anyway
I found that wifi performance and stability on the hero improved a lot when I changed my AP from dynamic 802.11 b/g/n operation to 802.11g only. I've seen other boxes with linux having similar issues with this AP (D-Link DIR-655), which points towards a driver issue. Wifi works better on Linux kernel 2.6.30 and later on notebooks so things should improve once HTC produce a build that include a more recent kernel. Wifi was quite a headache on notebooks too with the drivers in kernel 2.6.27.x that is included in the current hero firmware.
I have same problem - frequent line drops whne full strenght signal shows
I also have a Linksys WRT54G - never had any problems before.
tried wep and wpa -no difference.
Also tried some "always On" utility from the market place, it only helped reset it quicker.
As stated above, mine got more stable when fixing router to WPA2+AES but I now realize that I still do experience connectivity issues, although less frequently then before...
i don't think this has anyting to do with the router. I got a router from HUAWEI,forgot its brand, but not linksys for sure. I've tried the university wifi as well. they all have the same issue.
Mine is working great with a Belkin.
Looks like a problem with the Linksys firmware.
Anyone tried a firmware upgrade on the router?

Indeed, if you read up just a few posts, you'll find that question answered
that said, although things seemed initially to get better, I'm still seeing regular drop-outs with the upgraded router, and now still with the Hero upgraded to the HTC 2.0 ROM.
I do note that it seems to drop most when I'm sitting quite close to a different strong wireless client, e.g. a laptop. Perhaps the Hero just isn't a strong enough signal, and gets swamped?
Anyone else notice a correlation between dropouts, and proximity to other clients?

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!!

Help with fixing Wi-Fi

I have reached my wit's end trying to resolve my problems, so I'm posting here for ideas on fixing this, any input is appreciated!
When this started I was on stock, rooted, ICS 4.0.3 and had been for months. My wife has a nexus s with the same config and hers works fine.
Last week, my daughters sidekick 4G stopped having wi-fi internet connectivity. I turned her wi-fi off, then back on and it was fine and has been ever since. Later that night, my nexus did the same thing, the same procedure resolved it. Ever since then, my wi-fi will only work for 1-5 minutes after turning the wi-fi on. This is the only thing I can think of that changed that could have caused this. This was the first night we connected her sidekick to wi-fi.
The wifi symbol is up there, it'll be blue for up to half an hour, but won't have internet connectivity for long. One thing I noticed pretty quickly was that even though the grey wi-fi symbol is there, I can't access the router settings at 192.168.1.1 from the phone. I thought the grey wifi symbol still indicated I was connected to the router still, but it's not working. Each time this happens, I can turn wi-fi off, back on immediately and it'll work for 1-5 minutes. It appears that the more I constantly use it after turning it back on, it seems to maintain connectivity longer.
Last weekend, just after these issues started, I visited my sister and my phone operated on her wi-fi all weekend just fine.
When I came back home, my problems started immediately.
Here's what I've tried in pretty much the order I tried them:
I started by uninstalling avast, facebook, and autostarts
selected "Forget network" in access points screen and reconnected
Factory reset
Wipe dalvik cache & fix permissions
see if it worked without sim card in (it didn't)
flash GB broadcom driver
Switched router channel from 6 to 1
flash stock 2.3.6 (wi-fi problems still present)
flash OTA ICS (still had problems)
flash stock 2.3.6
flash OTA ICS
re-root
Flash PixelROM 1.60 LiteTouch
factory reset router (No wifi problems on using open network and default SSID for 30 minutes!)
resetup WPA Personal security and rename SSID same as before
Worked for another 15 minutes or so after this
flashed stock 2.3.6
flashed OTA ICS
re-rooted
Restored nandroid backup - quit working after this step
Factory reset router - worked for about 15 minutes, I decided I was ok so I setup security and SSID as before, then it quit working again
flashed PixelRom 1.60 LiteTouch
flashed stock 2.3.6
Flashed OTA ICS - THIS time I did not restore my google backups from the cloud, fearing that this was somehow restoring something that was causing me problems. It did not help.
Changed SSID on my router and reconnected phone
I have spent countless hours trying to fix this. I don't believe it's the hardware because the router factory reset seems to help quite a bit, works fine on unencrypted default router settings, and it worked on my sister's wi-fi.
I have nmap and wireshark and have a basic working knowledge of them. I have adb setup and usable on my computer. I also have dd-wrt installed on my router and have for years. Is there any kind of IP or hardware logging I could perform with these tools to help figure out what's going on??? ANY help is GREATLY appreciated!!
Well i'm no expert with any of this, but it sounds more like a router issue.. If both your sidekick and nexus have the same characteristics of failing wifi, it cant be the devices..
If you've already reset your router and it does the same exact thing, maybe it is something wrong with the router itself. You said it connected fine at your sisters house, so it cant be any hardware within the phone.. The only thing I could think of is maybe try a different router in your house to see if it works? If that helps get rid of the connectivity issue, then you can just get a new router and be happy with the wifis
I don't think a *hardware* problem with the router would only affect 1 device connecting to it wirelessly. I would think that kind of issue would affect all devices on the network.
Which makes me wonder if there's a setting on the router that may be causing it somehow, or some combination of packets might somehow cause the router to block my phone.
But again, I'm open to ideas here and I appreciate your input. I think getting another router will be my next step if I don't hear anything better by the time I get my next paycheck.

Ohh, I thought you had said that both the sidekick and nexus were having problems connecting. My bad.
But yeah have you changed any settings on it lately? Or messed with anything related to the router? Some setting may be kicking your device off after 5 mins, maybe some frequency setting or something dumb like that, I have no clue.
I know how it feels to have funky wifi, so I was only trying to help. good luck
Have you removed DD-WRT from your Wireless Router and back to stock OS? I had a Linksys router with DD-WRT and after about 3 years it started working so weird it became useless with any device. Had to buy a new one.
BTW, are other devices connecting fine to this router?
As swamp goblin stated, I would try with a new router.
It sounds like an issue on your router (or AP) with mixed client settings. I have had this issue with an old Netgear AP.
Try forcing "WPA2 with AES only" if all clients support it, otherwise force "WPA with TKIP only". If you have mixed B/G/N devices, force the fastest mode that all devices support. I use "G only".
Then remove and re-add the router on all your devices.
Also check for router firmware updates, and if you use DD-WRT firmware, find the Wiki page for your model and revision and use the suggested build there. The DD-WRT database they have is a mess and should not be used!

I haven't removed it. I thought I had a model that couldn't go back to stock, but I WILL be looking into this. The other devices connecting fine are Sidekick 4G, Wife's Nexus S, Acer Aspire one, HP tx2000 laptop, and my wife's HP laptop. I also have my satellite receiver connected via ethernet.

THIS FIXED IT! I tried it first since it was the simplest solution and I've been 4 days with no loss of connectivity since I changed it to AES only, which all my clients do support! Thanks so much!

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

WiFi issues?

I previously had an Asus ac1900 with no issues on my S8 but upgraded to a TP-Link Deco mesh. I've been having tons of issues whenever all 3 mesh units are plugged in only on my S8. All other devices operate fine. On my S8, literally every few minutes, I get the exclamation mark and lose internet but have full WiFi signal. Sometimes it repairs itself and other times I have to cycle WiFi. An Honor 8 right next to my S8 at the same time has no issues. If I unplug 2 of the mesh units, obviously I lose coverage but the S8 is completely stable. I've tried all the WiFi settings on the phone. Anyone else or any ideas?

1) Have you tried to connect to 2.4 GHz and 5 GHz networks?
2) Forget the connection and re-connect again.
It might be that phone doesn't hop from one router to the other or has a hard time deciding which access point it wants to connect. I have a regular Netgear router, but a good one, so no issues.
Check if your router has a firmware update - helps sometimes.

No firmware update and no control over bands with any of the new mesh routers
Bump
I have the same problem too on my S8+. Hopefully this will get addressed.
I have the Deco mesh router and have the same issues. None of my other devices have problems, just the S8. So frustrating!

Try this if you haven't done so already... I was having the exact same issue. I changed the wpa/wpa2 setting from AES/tkip to just wpa/wpa2 tkip only and haven't gotten any more disconnects on mine. I was Rock solid last night and usually lose internet connection multiple times a night. I had found that in another forum so I thought I'd mention it here.
I may go back and try AES by itself tonight to see how it acts. AES is the more secure method.

You cant do this on the new mesh routers
I'm having the same problem with my Asus RT-AC66U router; I'll try changing the WPA setting tonight. My Pixel never had any issues with that router though.
I've got an unlocked US model S8.
Anybody have issues with Google WiFi? I was considering picking up a 3-pack...

Didn't know that. I'm using the Comcast cable modem/router and also Linksys E3200.
Last week, I upgrade my home router from Netgear AC1750 to TP-Link Deco M5 and experience the same thing. Both S8 phones lost the internet and with a notification of "Internet may not be available". That is when WiFi still connected. I even change the phone Wifi IPv4 to static IP instead of DHCP and DNS server point to 8.8.8.8 and 8.8.4.4, still the phone lost the internet connection once in awhile at home with the new TP-Link Mesh type router. It appears that the Wifi issue is worst or only with the Mesh type wifi system. None of the other devices at home have this issue including the old S6 phones.
I have the Orbi 3200AC and I was having the same problem with an S8 I picked up from Craigslist. Did a bunch of tests on it and Verizon ended up sending me a replacement for it and this one has been good. No idea what set it off.
Solved!
I have an AC1900 and having the same issues on the my Galaxy S8+, disconnecting frequently. Switched to Tkip security but the speed is limited to the 56Mbps. so I get the logs and see that somehow the router is detecting my phone traffic as DoS attacks. I disabled Port Scan and DoS Protection option on the the WAN setup!!! and it worked!!
