Hi,
I got a new Sony Tablet S a few weeks back and I have this really weird problem.
As soon as I on Wifi and connect to my college network, it connects fine and webpages open as expected.
But after a minute or so, all data transfer stops even though I am connected to the network. Initially I thought
it was a hardware issue with my tablet but when I went to my nearest McDonalds and connected to their connection, everything
worked fine and there was no interruption in the data transfer.
I tried a couple of other hotspots around town and they seemed to work fine.
So, now obviously its a problem with my college network. The funny thing is that my laptop, my cellphone and about a thousand other devices
connected to the same network work just fine and do not stop exchanging data all of a sudden.
I have tried various apps available on the Play store but none helped.
My (geeky) friend told me that the issue may be some sort of interference between the routers (Cisco Aironet series, I think), as every floor in my hostel has 4 routers, but he could not give a solution. I have also referred the problem to my system administrator but he too could not come up with a solution.
If anyone has a solution to this, please help!
Thanks in advance
Really strange.
I have a rule that occasionally works, strange probelms can be sorted out by a restart, if not, a reset mostly helps.
Can I suggest resetting your tab if not done yet!

Did both. Doesn't help.
you need to re-flash the wifi modules, which comes with the kernel usually. But I dont think that possible at the moment.
Can you elaborate?
I have the same problem with my tablet, and when I called Sony for technical support, they said that the tablet is not compatible with the router I have. Which in my honest opinion dont think is the problem.
But as a way around, what I do is turn off the wifi for few seconds and then turn it back on.
This way the problem gets resolved.
I hope it helps you.
I have exactly the same problem, unfortunately the problem is with the wifi in my home, my sony tablet connect and disconnects, or it stop transmitting after a while, but other devices (my htc phone, my tablet, ipad, iphone) doesn't have this problem.
and as you said, when I go to other places the tablet works fine.
Someone said me that the tablet is not compatible with the motorola router of my ISP
I've been searching but there is no solution, by now I turn off and turn on the wifi every time I lost internet
Thanks people, but this is hardly a solution. It means I need to turn on and turn off the wifi every 60 seconds to browse the internet. Bye bye downloads, buffering videos and installing apps through the play store
Is the Sony Tablet S the only tablet in the world that is incompatible with routers? Then Sony should make sure that its clearly listed on their website that routers from major companies are not compatible with our Tablet
I solved the problem .. at last for me,
1 - turn off wifi.
2- in accounts - turn off "auto connect"
3- turn on wifi ( test if work )
4- reconect the accounts
too simple .. but works , try it..
I am sorry but its not working (that is if by auto connect, you meant auto sync)
Are you sure you are telling the solution to the problem I mentioned or something else?
Hi, I was suffering exactly the same problem and it boiled down that was a compatibility issue with the router. Unfortunately I could not find any other solution but replace the router itself!

Looks like I have to do the same. except I cant make my institute change their routers
What kind of encryption are you using on your router? Try disabling the encryption and see if the problem persists.
Also, what channel are you broadcasting on? It could be a highly populated channel, try changing that if you can.
I don't know what options are available through your routers configuration page.
I will enqure with my system admin and get back.
Meanwhile, I got a workaround to this problem. There is a freeware called MyPublicWifi which creates a virtual hotspot on my computer. This hotspot works fine and I can share my router's internet through this, even though it means I need to keep my PC on while browsing on my tablet.
I have experienced exactly the same problem since I bought the tablet. The router I have at home is a Buffalo WZR-HP-G300NH2. After a very long time trial-and-error, I have found a solution to it.
(1) Router setting: Force to set the 300Mbps mode of Buffalo router to 20MHz, not auto nor 40MHz. Some routers may display 150Mbps mode.
(2) Tablet setting: Settings->Wifi->advanced->Wi-fi disconnect policy, set to "Never"
You may try it and I think this will resolve the wifi disconnection problem. As for the reason, I think it is related to 11n because I have not found any problem with 11a/b/g router yet.
Hope this helps!!

Ive discussed this problem multiple times, but im reviving it as i have some new information.
my xv6800 on dcd 3.0.1(will flash to 3.0.4 later today) has an issue with the wifi. i tested and discovered that the problem persisted on the stock rom, and after more testing, i think i ahve narrowed the problem down to one possible culprit..maybe
Multiple AP's with one SSID.
My wifi worked at home with few issues, and it works off campus at an place with an AP that i spend time at. the issue comes up when im on campus and i connect to the APs in the dorms and the classroom areas etc...
everywhere else, the SSID's are unique, so there is no confusion(for my phone) but when im at school and i use it, i can connect to the AP, named "buwireless", but when the phone goes to standby and comes back(and tries to connect again) the wifi shuts off and wont come back until a soft reset. what i have been able to do, to be able to use the wifi at school, is to remove the settings that it saves, and just manually connect each time.
I did this because i think the problem occurs when the phone has to connect to the SSID that it know, "buwireless" but the problem is that there are multiple AP's with that same buwireless ssid but with multiple MAC addresses. is it possible that the many APs with the same ssid could be giving me issues?
i dont know what else it could be given the fact that it works very reliably in most places, but at school its not like the phone doesnt work well with that ssid, its that the wifi on the phone actually stops working when it is confronted with that ssid. it wont search for others, and wififofum wont work either.
any more thoughts would be appreciated, and of course similar experiences would be interesting as well.
thanks
Hi, is anyone has the same problem? When I'm connected at home to my Tenda router (WIFI b/g/n) after cca 30 min. my phone WIFI stops sending and recieving data, Skype is offline, etc... but WIFI in phone is stil switched on. After I switch WIFI off and back on (on my Samsung, not on my router), everything works good for a while and after cca 30 min. is situation the same. Is there in Samsung any WIFI sleep mode or something like that? Or some settings, which is not visible? Any other suggestions? Sorry for my poor English. Thanx in advance.
I'm having the same problem. But I did a factory reset and it works fine afterward.
And just few hours ago, I encountered this problem again. What did to get this error was, I pressed "on samsungapps" and it failed to update and thus results wifi connection stopping. What about you? Also my Kies air is not working.
are you guys sure you have wifi sleep policy set correctly? just to be sure, settings, wireless, wifi, menu button, advanced, wifi sleep policy to NEVER.
Yes. And also even if i manually disconnect and reconnect the wifi back. The data still doesn't come in. It is stated there as connected but no data at all.
Somehow Wifi keeps searching every few seconds, even thought it's connected.
This is bound to cost in battery life too.
I have reseted router to default settings, disabled n mode, disabled security (only mac filtering is on), disabled all unnecessary features and PROBLEM IS SOLVED !!! Thanx God Tomorrow I will experiment with router settings to know, what was causing this error ;-)
Well at least u're connected, I'm facing the same problem as the thread starter. No data flow at all. Browser showing me offline msg. I had the same problem on the 1st day with the phone after I woke up. previously playing with most of the default aps. So i'm not sure what went wrong, did a factory reset and it works fine.
Until, few hours ago, I tried my kies air which didn't work. Browser couldnt load the address given. And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me. At that point the wifi is still working, i leave my phone for about 30 mins, and when i came back. The same problem which happened on the 1st day came back. I was hoping to find an answer here so I didnt do the factory reset it. On another note, the phone wifi works after restart, but wouldn't last.
Edit: The wifi works after i resetted my modem to default. oh well. at least that solved it.

Hi,
Did you find out what setting was causing the connection issue? I also have this problem with my Tenda router. I thought it might be the wireless N, but disabling that doesn't fix it. I have a wireless distribution system set up with other tenda routers so didn't want to disable all the settings to troubleshoot if i can help it!
Thanks

I have the same problem, my router is N and the conection between SGS2 and my router is bad. Any idea?
Same problem here, I'm running WZR-AGL300NH in access point connected to my Ubuntu Server. Everything else works in the house just fine but SG2 stops transmitting data after a while.
I recently upgraded to KF1 firmware (and unknowingly wiped out whole phone, being on the bleeding edge and that didn't seem to help.
I would very much appreciate all tips because this problem is very annoying!
Additional Info:
- Buffalo is running latest firmware
- Authentication WPA2-PSK
- Encryption AES

Same symptoms here. Cisco DDR2200. WPA2 PSK. Haven't tried fiddling with the router yet.
This seems to be a common problem. Anyone knows of a definitive fix?
Bump...I have the same problem and the issue persists even after i reset the phone

Glad I found this, thought it was the ROM I had flashed to the phone (which is VillainROM)
I keep losing connection from my phone via wifi like everyone else in this thread
edit: I've just assigned my phone an IP address via my routers settings and I can connect to the net again
Also when it wasn't working, I couldn't ping the phone. When I assigned the IP just now I still couldn't ping it.
When I did a tracert to it, I could get to it when the IP was assigned and when it wasn't.
I have no removed the assigned IP for the phone from the router. Wifi connection is still working after disconnecting/reconnecting wifi on the phone.
I can also now ping the phone, where as before it was getting timeouts.
Also when it wasn't working the first time when I did a tracert it was showing up as HPsomething (didn't make note of the numbers)
this time when it is working it's just showing up as the IP address when doing a tracert.
Another update:
Just checked my printer, it has an IP address manually set on it, which at one stage when the phone wasn't working for internet it had the same IP as the printer, hence when tracert'ing it I was going to the printer instead of the phone and getting the HP etc back.
When it wasn't working at that time and looking at my routers DHCP list, it had the MAC Address of the phone against the IP that the printer has....
So I've got some issues with how my own network is setup ^_^ which looks like is causing me grief.
So the issue is with DHCP? Setting a static IP fixes it? I'll have to try, but I doubt this is a problem with the network, as all my other devices use DHCP without this problem.
I have the exact same problem!!
It's really annoying.
i was having problems with wifi too.. it keeps scanning and checking, etc, signal dropping for no reason..
fixed mine..well for me it worked
backup ur phone ( i dont take responsibility if ur phone catches fire or dies or chases u around )
u need to be rooted
download FXR WiFi fix and rescue from market
and just run the app.
now my wifi signal stays constant speed and i get good speeds
alternatively try
WiFi Fixer
both of them will cause high battery usage..i think since it keeps the signal at maximum.. so only enable wireless when i need it or use juice defender or green power.
greenpower seems great. using this at the moment
Hey guys,
I have a problem with my wifi...
Here is the before: Wifi works about 70% of the time, occasionally the connection would be dropped (as in "no network access", it still said it was connected).
Here is what then happened (in that order): Wanted to find a less crowded channel and installed Wifi Analyzer. Quickly decided that Channel 1 would be cool, browsed to the router configuration on the Desktop machine (LAN connection), changed the channel. Back to home on Android (don't remember whether via the home or back button). Into settings to see whether I would have to rescan or whether it would pick up the change of channel itself. It couldn't connect... It scans and attempts to connect, but doesn't
What I tried:
I restarted the Galaxy. Still couldn't connect.
Deleted the connection and re-entered the passphrase. Still couldn't connect.
Uninstalled Wifi Analyzer. Still couldn't connect.
Restarted device again. Still couldn't connect.
(At some point during all this, probably quite early, the Wifi symbol also stopped showing up in the status bar. Doesn't appear no matter whether Wifi is on or off)
Switched back to the channel I came from. To no avail
Switched of encryption on the Wifi. Still to no avail
Any ideas as to what might have happened and, more importantly, how to fix it? As I said the connection itself has never been the most reliable, but this is a different league
Thank you everyone!

If you haven't tried it yet, reset your router. That fixes the majority of Wi-Fi issues out there. If that doesn't work, it may be your router itself. Certain routers have more issues with mobile phones than others.
You may want to go to a friends house and try connecting to his router and see if you can troubleshoot and isolate the issue. Either way, best of luck...

Damn you sitecom router!!!
Alright, one thing I hadn't tried until now was to restart the router. That fixed everything including (for whatever reason) the lack of the Wifi symbol!!
So if that is possible feel free to delete this thread! I didn't find the option anywhere...
Sorry for the unjustified disturbance

Sometimes when I wake my nook from sleep it wont connect to my wifi.
When i go to my Wireless settings, it shows that my WIFI is On but it it does not detect any networks(there are over 10 wifi networks in range (apt building)).
I go to turn wifi off and it grays out and I get a message that says "Unable to stop Wifi".
The tablet locks up and reboots. Has anyone else experienced this?
I am running sw ver 1.4.0 with the kill OTA procedure setup.

I have seen this once or twice. A router reboot can help a little, but it hasn't been enough of a problem for.me that I've tried to do anything else. All of my Android devices have had problems with my router now and again.
I dont think its my router. Ive got 3 Android phones, A kindle fire, 1 Asus Transformer, multiple laptops, Xbox 360's, wii and multiple IOS devices hooked up to my network and none of them have complained about my wifi being busted. The nook tablet is the only one doing this. My first nook tablet did do this at all. I am wondering if this one has a defective WIFI chip
Yes, I have this same problem on my home wifi.
But in my office, everything is ok.
I have had the same issue. I just reboot the NT. It happened this morning, it was charging overnight with the low battery warning comming on last night before charging. Perhaps that may have something to do with it. I'll try to see if it's on it's charger next time it happens.
I had issues with mine doing that somewhat often. It would even happen during use. I was non rooted with a couple of sideloaded apps. Finally I got fed up and took it in. They swapped me out for a new one and I've had zero issues since.
I was lucky in that both me and my wife got these and I had a point of reference. Her tablet had no wifi issues while mine did. That was what led me to believe there was a problem with mine.
If you keep having the issue, you might want to think of getting it replaced.
WiFi problems only on one router.. Connected - No internet.
The WiFi on my Rooted Nook tablet works great at home, at in-law's, at parents, at neighbors houses. But at church it would find the signal and accept the password then said - "Connected - But no internet". It had full bars. The IP address was some generic number with mostly zero's. I had access to two different iPhones at the time and they both worked and connected to the internet with appropriate sequential IP addresses. I rebooted the D-Link router and my Nook Tablet with the same results. Any Ideas??

Me thinks that your deity doesn't like the idea of you rooting B&N's device.
What are the IP addresses of the other devices, the NT doesn't like nonstandard network protocols.
NT reboot required to get WiFi working
I purchased two Nook Tablets for my kids. Both are rooted using Snowball-mod. Both typically work well, but then refuse to connect to my home wireless network after some time. I have several other laptops and PCs connected to the same WiFi network with no issues. Only the Nook Tablets are unable to connect (after several hours of use). Rebooting the Nook Tablet always solves the problem... until it happens again. I have not found a patter to this yet (i.e. what might be triggering the WiFi to stop operation). If anyone find a solution to this issue, I would love to know what is found.
Several of us have found WiFi will lock out when the device is in sleep mode. Killing WiFi prior to sleep seems to stop this mysterious behavior, for me anyway.

Is it known whether a un-modified ("stock" B&N NT) also requires WiFi to be disabled before entering sleep mode? If this is not an issue with an un-modified Nook Tablet, then perhaps this issue can be corrected soon.
Hi all,
The NT does not support Channels above 11 on WiFI networks...so if you router is on Auto-mode, it might choose a channel higher than that...and puff...no net...
Also, I had a Netgear Router which had some WPA2 incompatiblities with my both my Blackberry and my NT. Flashing the Router's firmware, also solved my problem.
Hope my experience is helpful.....
Cheers,
Gizmo
Gizmo, thanks for the suggestions but I do not think this is a router channel issue. What is happening is that the NT WiFi seems to lock-up (possibly driver issue). Bringing up Settings and tapping to turn off WiFi results in a grayed-out WiFi toggle (not "Off" but inactive). Attempting to touch WiFi again after this produces a message similar to "WiFi is not responding" (I don't remember the exact message now). My routers are set with fixed channels 1 and 6 as well.
Hi, I'm sorry, but I'm having trouble getting WIFI to work on my NT. The thing is: it only works disabling the password on my home network! But I want to maintain a secure connection... Can someone helpe me? Thanks in advance!
waking the wifi
Don't know if I'm late or not, but I actually found a resolution to this issue by downloading an app from the Google Play store called Wifi Manager. It's free and as soon as you launch it, it'll instantly re-wake and reconnect your wifi within less than 1 second. It's not intended for that use but it helps big time!
I recently bought a Galaxy 4.0 player and so far everything is spectacular.
The only problem is that I can't connect to the wifi network at my school. Everyone else can connect with their laptops and itouchs. I try to connect and it says "obaining ip adress" and then a few seconds later will say "disabled".
Every other wifi network I've tried to connect to has worked perfectly.
Hopefully I'm not missing something obvious.
Any help is appreciated.
Thanks
I had the same issue. Go give IT a visit and see if there is a second network. My school has two of the same networks. One is password protecred. That is the only solution I have found so far. I hope all goes well.
it is an issue with the router ..
actually not the router either .. it may be using one of the newer encryption which is not supported
