Galaxy tab2 with WiFi problems - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hi folks,
A friend of mine has a Galaxy Tab2 running android 4.1. He is having problems connecting to our WiFi at home.
We have wep set up on the router and it works fine with two laptops and a HTC flyer.
The tab shows good signal, but then shows networked cancelled due to poor connection. Various locations tried.
Any suggestions folks? I have had a search of the forum, but didn't see a similar situation. Looking quickly at Google, it looks like plenty ood people have had problems, but no real solution. A factory reset seems to be a suggestion, but would rather save this a last resort.
Fingers crossed you guys can help.
Cheers,
John

You can try these:
1) Setting your Router's 802.11 mode to: 802.11n (If you don't have old wifi enabled device everything will work fine)
2) Disable any battery saver apps, they do turn off Wifi - when screen goes off (+several other like location based wifi switch offs n ons)
3) Tweaking Advanced Wireless settings on Router might help.
Advanced settings explained at this location: http://www.dd-wrt.co.in/wiki/index.php/Advanced_wireless_settings
& if device is unable to connect at several wifi locations then probably there is something wrong with device i guess, getting it checked at Samsung store will definitely be better solution.

[Q] Wifi at home issue

Hi Everyone.
I am not a developer nor really tech savy, but I do know how to adjust a few things. Anyways, I just got my Infuse 4G, loving it so far except at my home. I have really fast internet connection and my router is new and is Cisco. My laptop, desktop and tablet all work really well. My infuse though will connect and tells me that it has a really strong wifi connection, but I can't open anything for **** such as a browser or market app. It works fine at work and at any att wifi hot spots.
Can anyone advice me on this? Sometimes though, it works fine but about 85 % of the time at home, I can't open any internet connection although it says that I am connected to wifi.
I am about 5 days close to returning this if this problem can't be resolved.
Any help will be really and greatly appreciated.
Thank you.

Probably your router. If it's Linksys-branded Cisco of the "saucer" form factor - find something better. Linksys-branded Cisco hardware sucks these days.
I suggest finding a router that is supported by DD-WRT - I have always been disappointed when running routers with closed-source factory firmware.

I would think that if it works well at work and att hot spots that this would point to ot being an issue with the home router.
Have you tried resetting the router?

resetting meaning turning it off and wait for a few minutes and turning it back on?
No, but if that was the case, my other devices shouldn't work neither no?

Some routers are buggy and don't play well with some devices.
90% of the time it's the router's fault.

Wifi Issue: sell GT7 or wait for ICS

Dear seasoned Xda members,
I love my GT7+ and have enjoyed the versatility of the Android Os (my first device). As I carry the device around and (attempt to) use it at work the size is perfect. However, I have terrible issues with the WIFI. At home there is no issue - but I work in a hospital, and the device is only good for me if it can get WIFI.
Well... in the hospital it will connect to both the "guest" wifi and the "secure" wifi (for which my device has been setup), but in both cases the connection just "dies" after about 2 minutes. The only way to get on again it by re-booting the device.
I had hoped that all of the firmware updates would address the issue - and I have read that some routers are troublesome for the GT7+. Unfortunately I will have little control over what routers are being used.
The device is no use to me if I can't use it at work - and Im wondering if I should sell it or if ICS will resolve the Wifi issue.... I would appreciate any guidance even if its speculation.
[btw the device is entirely stock, not rooted, and using ADW instead of TW]
Cheers!
Here's samsung's ics update list.http://androidandme.com/2012/02/devices/official-samsung-android-4-0-update-list/. You'll probebly have to wait until Q2 or Q3 for ICS, unless someone ports CM9.

I guess it was my fault to get the WIFI only version thinking it would be easy to switch between networks. Seems like a bug that they should have wrinkled out before shipping a "Wifi-only" device.
In any case, if anyone is looking for another device to play with - shoot me an email (aliota [at] gmail.com)
I had the same issue prior. I bought this Tab twice and with both devices the same thing happened at work aswell. At home it was working perfect. At work any wireless connected but dropped in like 2 minutes. Very Frustrating. I was actually thinking of picking it up again assuming the issue had been fixed..

Have you tied to do a factory reset on the device and then reconfigure the wifi connections? I bounce between many wireless networks during my day and the connection is stable.
I did have a few reboots until I set the wifi to turn off with the screen and never to turn off when charging, now the device is rock solid.
I believe that once ICS is dropped there will be some custom firmwares (ROMS) available for the device. Every new device I see posts like this where there is one feature or another that is flaky, once the developers start working their wonders on it the device becomes wonderful. The biggest hold up right now for development is the WiFi driver. Based on history of other devices, eventually that will be overcome as well.

Interesting... I've tried this in the past without any luck, but will try again. I really want to keep the device because it is quite powerful and the 7" size makes it much more portable than a 10"+ tablet.
Thanks for the feedback.
I have noticed some wifi issues with mine also but they dont seem to big of a deal for what I use mine for. I would really recommend keeping it as it is duel-core, lightweight, can even fit in some pockets.
But rather you keep it or not I suppose depends what you use your tablet for mostly I suppose.

[Q] Wifi

Not to continuously post stuff on XDA about this phone...but I am curious....my Wifi keeps disconnecting and reconnecting....depends sometime 1-2 mins into using Wifi and somethings after using it for more than 1 hour....none of my other devices have this issue and I was just wondering if anyone else has this problem with this phone...thank you
Edit: It still happens....hmm

I've been having the same issues... I have a laptop that doesn't seem to have any problems with my current router (Medialink Wireless N router I got off Amazon - good router until this issue...). It also doesn't matter how close I am to the router either. I've been sitting 2 feet from my router, and it will still continuously disconnect and reconnect. Let me know what your findings are...
Idk if this will help: settings/wifi/menu/advanced/keep wifi on during sleep. I have mine set to always, no problem here. If that doesn't help try assigning an ip through your routers dhcp.
Saint sent this from his Q using xda premium
Ok....so it does still happen....on my Netgear 7550, Linksys E4200, Linksys E3000, and almost every other network I connect to...it is really frustrating...
It happens to me when I'm in my apartment bedroom some on the far side (I normally plug it up at night to my right on the headboard) which is about furthest from my router I can get inside...but otherwise I don't have the issue when I'm closer. I've started wondering if the phone just doesn't pick up wi-fi as well, though in fairness I have a single-antenna fairly cheap Rosewill router (RNX-N150RT).
Change the wifi ip settings on the phone from dhcp to auto. Mine was set to default to dhcp.

I'd have to think you guys have bad hardware, or something else not playing nice... I have connected to MANY access points (even in different countries) and never had an issue with it dropping. I even make wifi calls for long conference calls, so I would definitely notice if it did drop...

Yeah, I have the same issue. I've discovered that it doesn't disconnect if I'm within 5 feet of the access point, which isn't exactly a great option, but does suggest maybe a software fix or a straightforward hardware hack like the Atrix 2.
Ok so even after the update the wifi still drops....even when i am right next to the router....but I can say that when i am using WiFi tether it doesn't drop the tether connection....it all seems weird to me...

Possible solution - try this and see if it works for you
Was running into this problem on my new Pho Q (too fun calling it that), where it would drop wifi and report a connection was available on the left side, then connect again, every 15s to a min.
To resolve (at least so far now for me for about an hour):
Settings - Wifi - Menu - Advanced:
Uncheck Show Reminders
It seemed that having it popup a reminder of available networks could be related to it noticing my available network every few seconds, and it seems to have helped me. Try it and report back. :highfive:
Ok, seems its still happening, but far less often at least. When I have some time, I'll try to do an A-B-A test but it does seem better than it was before disabling the setting.

I still seem to have this problem - anyone figure out a solution? I'm getting really tired of not being able to use wifi at home, since I get next to no reception... Gets frustrating really fast when it disconnects and reconnects every minute or so

Someone thought it was related to smart actions - do you have any of those enabled?
I've never had any issues with wifi - and I've used many different types of routers and security models.
Have you tried changing your wireless channel on your router or gateway? By default most start on 6, so changing it to 1 or 11 might reduce interference from nearby wireless signals. Are you a long distance from your router/gateway?

It'll disconnect and reconnect even if I'm 2 feet from the router. I just tried changing to channel 10. I'll report back how it goes. I do live in an apartment building with tons of wifi networks, so this is a good suggestion. Thanks!

Tried changing the channel, but still disconnects and reconnects often. None of my other devices (laptops, tablets, other smartphones) have any issues keeping connected. I'm still at a loss...
Anyone have any luck fixing this? When my wife's photon Q connects to our home network, no problem. No drops whatsoever. But when she connects to her work WiFi, despite a strong signal, it would drop every few minutes.

[Q] Wifi Problems

Hi,
Starting to lose my patience with this device now. Such as shame that this lovely piece of hardware is strangled by poor software. I've already put the device on ebay and withdrawn it because its so slinky and I really want the issue to be sorted. I have no option but to go with the ipad mini at this rate, it just works!
Using odin I've successfully upgraded to ICS with P6800DXLP8_P6800OLBLP7_P6800DXLP7_HOME.tar and XXLQ1_OXALQ1_ATO My wifi keeps dropping out, ive tried it on three different routers etc and still the same issue. Tried CM10 and that reboots on me. Ideally i want a stock rom that works without any niggles on my Euro p6800. Any ideas, i'm really trying to make Android work for me, ive searched the forums like a good boy but no real answers anywhere.
:cyclops:
I can't help but thinking... if you are fed up with the Sammy device, why not switch to something that is completely open, like the Nexus 7, instead of a closed ecosystem like Apple's? Seems like there are other (better) choices out there than the iPad mini.
I'm sorry you're having troubles. Please feel free to give me your tablet. I could always use two!
Barring that, here is what I would suggest that has worked for me:
I have always had "advanced WiFi lock" from the play store, and it appears to have improved WiFi performance even when I had ICS.
I had locerra's cyanogen 10 ROM for a spell and really liked it. I then did some research in the development section and found Daniel HK's Paranoid Android ROM v. 2.55 and have enjoyed it even more. WiFi performance has been consistent and stable on both custom. roms.
Do some research and have a go at it.
If not, i can give you my address as I am currently living in Mexico and you can ship it to me!
I didn't experience any wifi issues at all until today. I'm staying with a friend for the week in Canada, and wifi k3ps dropping out. It seems that only a restart will solve the issue, and the network then falls out of range(even though I'm next door to the router). I'll give the app mentioned a try.... But any other thoughts please let us know! I'm on the leaked ics rom from Open Austria, rooted.
Update: "Advanced wifi lock" app has solved the issue, thanks! But we shouldn't really need to download the app.. Any ideas of how to solve such issues natively?
Sent from my GT-P6800 using xda app-developers app
Correction, sadly the app didn't solve the issue.... Still having intermittent wife but HTC is connected constantly.
Sent from my GT-P6800 using xda app-developers app
Ensure you don't have BOTH 2.4 GHz & 5 GHz enabled on your router at the same time.
Use one or the other.
After disabling 2.4 GHz band, and using 5 GHz only on my Billion router, my device (P6810) had no wifi drop-out issue. Same if I use only 2.4 Ghz band only.
Hope it helps.......
BTW, I would suggest LP8, such as my SkyHigh ROM, having "fixed" wifi issue for most........ But try the above first

Did you fix your issue in the end? I've tried changing settings on the Cisco Valet router to operate in just one wavelength but there is no such option... I guess it must be a old router. The wifi lock app didn't make much difference either unfortunately.

Thanks, The firmware on my mate's Cisco router was out of date, wifi connection much better but it still cuts out and appears to only reconnect if I restart. Even a "quick reboot" from within Rom Toolbox Pro doesn't reconnect. Annoying issue... It even cuts out midway through a skype call with my wife (but no issues on mates ipad or my htc) Also no issue with my wifi connection back in the uk. Very weird. Any further ideas appreciated!

Just wondering of the connection is secured? Does it cut out on open connection?
If secured, did you restore wifi settings with any particular app (ie. Titanium)? If so, you could try delete/forget wifi connection and manually enter the password instead
Or, delete/forget wifi connection in settings and restore with titanium backup. You usually have choice of "101" or "XML", try one then the other, reboot each time after restore.
Edit: if you have another device to set up a wifi hotspot, open and secured, and test?
Sent from my GT-P6810 using xda premium
It's a secure network, but i've tried forgetting the ssid and then reconnecting, but it makes no difference... Still patchy connection. I don't want to make the network open as it's my mate's network not mine.
I downloaded an app called "wifi manager" and it seems to be working 60% of the time, which is good enough for the moment. When I get back home to my own wifi network I expect no connection problems as it was working fine when I left last week probably the issues were due to my mates awful Cisco router and not the GTab!

I think it's the WiFi driver in the version of your ROM.
There is no reason you should be having to amend settings on a router because in most instances, you will not have access to a,ending the router.
I'm currently living in Mexico and I'm dependent on several WiFi access points around town and intermittent WiFi where I live. I can safely assume that the technology isn't the latest and greatest down here and I don't control any of those settings.
I am not experiencing the problems you are describing.
I think you're right, it is the wifi driver. I've just tried connecting to the open wifi network at Toronto airport, which connects fine on my htc, but i need to restart my GTab in order to connect to it. I'm running an official Samsung ics rom from the European carrier, Open Austria, (downloaded from samobile.com)... These issues only started when I left the UK and arrived in Canada. I'm wondering if the 3g roaming has some part to play in the error. Anyway.. I will try again when I get home, but anticipating issues.... How would I fix this? Do I have to reinstall the rom and all my apps?! (hope not, as I have this baby set up just perfect )

Ah, that says it all...
Check my comments about LP8 firmware mentioned in my first post here..... way down the bottom Was obviously missed. Posts after that, I assumed you had, since you didn't comment about it.
There is also a thread relating to the problem and the subsequentLP8 fix.
Either flash SkyHigh ROM (P6800 DXLP8) or official DXLP8.
Whether just flashing the kernel from DXLP8 firmware world do the trick, not sure, as I have a P6810. But as I said, flashing the firmware package helped most out with the "wifi bug"
Do you have root and custom recovery?

Just got my 7.7 3g P6800 back from Samsung in HK... Replaced Motherboard under warrenty due to super brick.
They installed LP7 ROM and when i got it here had wifi issues...
Read about it and found recomendations to change to LP8 Rom...
Now have installed latest LP8 Rom form sammobile
Wifi issues have gone away....For a week...Now back again.
Just dropping out every few minuets and not in range etc...

Possible solution to WIFI problems?
I have had major problems with WIFI in my 7.7. The Austrian ICS has dropped connections, went totally berserk in some locations and stopped working unless rebooted.
I have now diagnosed (I believe) that the reason is the use of channel 12 in any WIFI router. If the router does not use 12 there seems to be no problems. At home I can configure my router not to use 12 and after that I have had no problems. There seems to be some kind of conflict or the Tab is faulty in that sense.
I do not know if this can be generalized, but at least for me it worked.
Yes I had the same problem with band number.... My friend's router that my tablet had an intermittent connection with, was on band 11. As soon as I got back home to my router in the uk (which uses band 6) My wifi connection problems disappeared.
Sent from my GT-P6800 using xda app-developers app
Yes I Can say after doing alot of reading i realised its the chanel.
im using locked chanel 5 and seems much better..also wifi connection manager from play store.
still not the greatest and low signal even in same room to router but working i suppose.
Just funny how my S3 has a much stronger signal compared to the 6800 every wifi ive ever used.
Would be good if somehow the wifi drivers from S3 could be used somehow?

Need help please. WiFi problems, can't find an answer anywhere...

Boy... I hope someone can help me out here. I have been searching for weeks with no luck. I have been having an issue with my stock 4.2.2 p5113 Tab 2 10.1 unrooted. I can't get it to find my home network. I can see my neighbors, even took it down to Arbys and was able to connect to their WiFi with no problems... Just can't connect or even see mine.
I have an Asus rt-n66r router. Have tried every channel and different frequencies. Changed every setting one at a time to see if it worked and nothing. Well... I take that back. Last night I turned off encryption and it popped up shortly... But went back away. When I go into advanced it shows the Mac address but IP says unavailable. I set up a static IP and that didn't help. I have reset the tab and router and even factory reset the router to no avail. It just doesn't make sense. Got this router back in March and its worked fine until now. Nothing has changed except me recently resetting the router to try and fix this. I have done everything I can think of but still can't see my own home WiFi. Everything else connects fine. Galaxy note 2, HP laptop on windows 8, smart TV, smart bluray, iPhone 5c, etc and everything else connects. Have even tried turning a few of them off to see if that helped but still nothing...
I really hope someone can help me. Had this thing for 2 years next month and it has always worked but at this point I feel like throwing it out the window LOL.

Also use WPA2 encryption. Have tried just WPA and WEP push button but wouldn't find it still. And tried turning off encryption again and still not seeing my WiFi. Wanted to add that...

Is this the only wifi device you own?
If you own another wifi device, does it see your wifi network?

I tried every channel and none of them helped. Did reboot the router and changed everything and still not showing...

No... Everything else works and shows the network. Have laptops, a windows tablet, an iPhone, a smart TV and blu ray and some galaxy note 2 phones and everything else works flawlessly. This galaxy tab 2 did and all the sudden can't see my home WiFi. Can see the neighbors, can see my TV sync and even worked when I took it to the local Arbys and used their WiFi. Only none it can't see is my router. I've only had the router since march. It cost about 150 bucks... Figured it would be decent... And it has except this one issue now...

If a factory reset doesn't do it then your tablet is bonkers. If you scroll down to the bottom of list of networks is your network showing? Maybe it has (forgot ) your network?

I went ahead and rooted and put on the slimbean ROM and still issue persists. So today I hooked up an old 15 dollar router I had from micro center and guess what? It showed up. So I factory reset my good Asus router and hook it all back up and still won't find it. I'm at a loss. Everything else in the house is connecting to that router no problem. Its some issue between this tab and this router... Only thing I dont get is why it worked before no problem and out of the blue it stopped connecting to the router without anything changing. I've been at this now for the past 24 hours pretty much non stop and I can't figure out what's wrong...

Can you see your Asus router on the Tab WiFi networks at all? Is it at the very bottom saying "not in range" ?
Long press on it, if there you'll get option to "forget network" or "modify" / modify. If you don't see it them it's forgotten, try add new network,.

No... It doesn't show up at all. I forgot it a long time ago. I do see my TV sync for the remote control and I see numerous neighbors wifi names come up... But not my Asus router LOL. Its just so frustrating especially after what I did today and could see the cheap Tenda WiFi router from micro center that I don't wish to use anymore because its old and out of date. I really am about to pull out my hair lol

By "forgetting" a network you eliminate it from your list of networks, you then have to add it again as a new network. Could this be the case?
Images are examples of forgetting networks.
Pp.
No.. I understand what you mean. When I 'forget' a network, say on my phone, it will pop back up and I will have to click on it to connect to it. My home and guest WiFi names are no where on there. I scan and scan and they never show back up...

That's weird! I think you should consider rooting and installing a custom ROM, maybe a stock rooted ROM. I have Android Andi's CM11 4.4.4 KK running on my P5113 and it runs great. I suggested custom rooted if want to use the TV remote app, if not you should try CM11.

Do you have a link to that by any chance. I am new to this. I did root and use the slimbean ROM... And tried to use slimkat but I couldn't get it to work. I think it was my version of CWM I think... Thanks for all the help

Op says stock /unrooted so only way to go to a different kernel would be to root and flash custom rom, and that will probably fix the issue. .

Oh I did root and have flashed 2 Roms so far and neither have helped. Took the tablet down to McDonalds today and it was able to connect. But then went to a friend D's house, my phone connected to his WiFi but the tablet didn't see it. Seen his neighbors, but not his. So I am really lost at this point...
