You are not alone.

I always wonder why people that never had a problem like the one in question waste the time and space to say that they have never had that problem.

It seems however, that you are not alone. The BN forum is full of people with the same and similar problems with wifi. On both the Color and the Tablet models, those who have solved the problem report success by many different methods. The most common thread involves various changes made to their router setup. Some have slowed the max speed, others have changed their setup from type n to g. Others have changed out the router entirely.

Last week I had a similar problem. The tablet which had worked flawlessly for 2 months would connect up when asked and after a very short time drop out. Diagnostics showed that it was connected but not active. When the NT's wifi was stopped and then restarted the problem would recur. Even when told to "forget" and then reload the password. And of course power down resets were no help.

My personal solution was to change the routers security from WPA Personal to WPA2 Personal (It's a Linksys.) Since then it is again working perfectly.

I don't believe the problem is with everyone's routers. I believe that something gets screwed up in the NT wifi logic and a totally new connection has to be made. I also have a second wifi router (a Netgear,) with a different SSID but set up with the same security as the Linksys. The NT would always lock on to the second router and work just fine. As a double check, all other cpu's and devices continued working fine with the Linksys.

Try making a similar change to your router. If it then starts to work change back to the original setup and see if it holds.

Just took mine back to Best Buy this evening for this very reason. I had the one bar issue and I would constantly get the wifi error message on the notification bar. It had been getting progressively worse over the last few days and I figured i'd take it back while I still could. My son's kindle fire and all of my other gadgets are fine on my home's router.
[Barnes & Noble Nook Tablet] ishater:
I'm glad I ran into this thread. I have noticed this issue happening every now and then, but in no way consistent. I will try the security setting thing and see if that goes anywhere.
[Barnes & Noble Nook Tablet] zaptoons:
Personally, when I troubleshoot a problem I like to have all available information. So why wouldn't I want to know that not everyone has the same problem, therefore it's not necessarily a problem with every NT?
[Barnes & Noble Nook Tablet] LordGibson:
Agreed - it gives everyone the benefit of a big picture. Not to mention, the OP specifically asked, "Is it just me...?", inviting contrary experiences.

Now that we've established that it isn't an across the board problem, we can start to examine what's different between different cases. That's how diagnosing a problem and [maybe] finding a solution works. . . Otherwise, why pose the question in the first place? Misery loves company?
[Barnes & Noble Nook Tablet] The_Joe:
We would need to know what brand router, and if they have tried a static IP.

Also would be helpful if they could test there problem on multiple routers.

Once those steps are taken, we know if it is a conflict, defect, or software issue.

I would also be curious if this problem will persist when we have CM9?
[Barnes & Noble Nook Tablet] Eustace2:
I have a rooted NT running version 1.4.0 that I use on two Linksys wireless routers in our house. Both use WPA2 security. One has a fixed IP address and serves as an access point to the main router. I have not experienced any connectivity issues at home and the reception has been good even when connected to the most distant router. I have also used the NT at various hot spots and have not experienced any access issues. I received the DHCP error one time at my daughter's house and fixed that by restarting her router.
[Barnes & Noble Nook Tablet] eybarra2:
I, too, have been having a similar issue since I got my NT(1 week before Xmas). I leave WiFi on all the time, don't get out of the house much. It does seem to happen more often when charging. Reboot does the trick, but then I have to reload my widgets :-/ I rooted a few days after owning so never saw prob before root. Also, I use a rooted/custom rom Sanyo Kyocera Zio(I know, it's a piece o' sh*t, lol), and use Wireless Tether app. I used to have a cm7 Nook Color. I broke it before Xmas and just opted to upgrade to NT. Flashed NC had no prob connecting to my Zio tether at all. My rooted NT does not even see it(I know it's working bc my gf's iphone can still log into my tether, no prob).
[Barnes & Noble Nook Tablet] yourbrokenoven:
Just an update: After factory restoring using it for a while, and then re-rooting, I've noticed that problem 2 has never re-occurred. I'm not certain what was happening. Very strange. I reproduced the problem over and over before posting. I even tried resetting my router and modem just in case.

Problem 1 persists. Rebooting always fixes the problem temporarily, but if the device goes to sleep for a few hours whether charging or not, it will almost always need a reboot. I always try to turn wifi off and back on, but the device is unable to disable wifi during this issue. I never noticed this problem while the device was unrooted, though I'll admit I didn't keep it stock, unrooted, very long.
[Barnes & Noble Nook Tablet] kcpaynev1:
i had the same issues with my wifi in the past until i downloaded wifi locker from the market, its a free app, it basically stops your wifi from shutting down when your device sleeps for a while. just click the icon to lock it and click it again to unlock it if you want to shut your wifi off
[Barnes & Noble Nook Tablet] jon.01:
I have noticed some issues using the University of Toronto wifi connection.

1) Get Wifi Issue notifications often. Says "Wifi Issue" and "Cannot login" many times but can still surf without interruption.

2) Sometimes when turning the screen off I get disconnected from the AP and have to disable and re-enable wifi.

3) Sometimes the wifi just refuses to connect.
[Barnes & Noble Nook Tablet] eybarra2:
Update: found a thread here with a hack to allow the nook tablet to see adhoc wifi networks. Works pretty well, just takes slightly longer to scan for networks. As for the disconnecting issue, still present :-/

Just read thru this entire post again and it seems that its the Nook, not the routers. More people are saying the routers work fine with other devices than are saying they replaced the routers. I would guess that its the Nook software, and that issue was addressed in the 1.4.1 update. I blocked my OTAs so I did not get that update, and I still have this issue occasionally. I noticed that those that say there's work fine also got them recently(AFTER the update). Anyone else agree with this assessment?

Also, to those saying it doesn't even see their networks, those are adhoc networks its not seeing, the Nook tab will not recognize those at all, but there is a fix posted here that made my Nook see my network broadcast from my phone.
[Barnes & Noble Nook Tablet] SCClockDr:
[Update] Problem 1

An update on Problem 1 quoted above:

It happened yesterday went to grab the Nook to check on CM7 progress and You guessed it, locked up. So I rebooted and went about my usual activities.

Last night I went to check on the battery & I observed the attached:

NOTE the step drop in battery level just below the gg of "unplugged"

It appears that the Nook lost its awareness for some period which syncs with the locked up state I found WiFi in. I suggest others take a look at this to confirm maybe an hour after reboot to produce the step if it is present.

Is there a log to observe that might shed light on the situation?
[Barnes & Noble Nook Tablet] ldpryor:
I saw problems 1 & 2 while running stock 1.4.0 and after rooting (1 almost every time it went to sleep). I did a reset back to stock, then did the 1.4.1 upgrade. Left it for about a week and haven't seen problem 1 again. Rooted again using Indirect's SDcard method with Brian's updates & still seems good.
[Barnes & Noble Nook Tablet] TRS-80:
Maybe that's what they addressed in the 1.4.1 update? These wifi issues?

I have experienced problem 1 a couple times.

I am rooted 1.4.0 using Indirect's method and blocked OTA.
[Barnes & Noble Nook Tablet] spottedtadpole:
I have not had any problems connecting with mine, but I have had some problems with getting SSH port forwarding to work (Connectbot) at a university library. I tried my setup at another location and it works perfectly, so you might try different wifi hotspots.
[Barnes & Noble Nook Tablet] knuckhead:
For what it's worth, my Wifi performance has always been good.
[Barnes & Noble Nook Tablet] PepeladZ:
After reading the whole thread it seems like people who experienced problems with WiFi connection on 1.4.0 (rooted) are not experiencing them anymore or less frequently with latest OTA updates.

Maybe, there is a way to take drivers and corresponding settings from latest updates and put them to work in 1.4.0?

Can anyone tell anything on this matter?
[Barnes & Noble Nook Tablet] rcHumanz:
Well, I'm getting similar problems on 1.4.2 rooted. So not sure if all the problems were sorted by the updates. My wifi at home doesnt always connect. After a week of cycling through a connecting-disconnecting loop, and repeatedly restarting wifi and the nook, i woke it up this morning and it connected at once. I'd even tried restarting my router a couple days ago.

It seems as if the NT doesn't always honour the ip lease (a problem that some android devices seem to have). I was going to try assigning a static ip this morning but as it connected, and the ip lease period is one month, I'm hoping it means I won't have to deal with disconnection issues until the month is up.
[Barnes & Noble Nook Tablet] PJLLB:
Have you checked your router setting for which channel it's using? I've experienced problems like this, and when I checked to see what channels were in use, there were multiple neighboring wifi routers picking the same channel as my router, which was set to automatic channel selection. I reset the router to a channel I knew was free, and have never experienced the problem since. I'm running stock Nook and an Android for Nook card (dual boot) -- I used Wifi Analyzer on the Android side to see what was going on with the network spectrum. Just a thought.
[HTC EVO 3D] sumredhed567:
I guess no one here uses wifi so its not really a problem but I for one am on wifi the majority of the time. In every sense 3.5 rom I've ever used the wifi will cut in out (as in it disconnects randomly and then connects again). This makes downloading files and playing games over wifi impossible. These roms have been out for a while and I feel like this would have been something that's already been fixed. Is there some fix or something I'm missing here as I am in love with joelz 3.5 rom. Thanks
[HTC EVO 3D] sumredhed567:
So everyone that uses joelz 3.5 rom doesn't use wifi?

Hi All!!!

There is some user SGH-i957 that can solve my doubts?

Is the SGH-i957 AT&T sim-locked???

Is the SGH-i957 AT&T S.O. Honeycomb 3.2???

Italian is the language from those available in the system settings??

Is the SGH-i957 interface smooth and fast as SGT 10.1 or XOOM???

Has anyone tried to play 720p H.264 High Profile Videos??? Are smooth or jerky??? (in the SGT 10.1 & 8.9 with tegra 2 only 720p H.264 Basic Profiles ar playable without stuttering !!)

Has anyone tried to play 1080p H.264 Videos??? is it possible???

I would like to buy a SGH-i957 AT&T (used) because I'm interested to replace my SGT 10.1 (bought in Italy) because the Tegra 2 is really bad with H.264 720p video. Instead, I'm not interested in the LTE (only 3G HSPA in Italy for now).

Thanks in advance to those who want to answer!!! :)

P.S. Sorry for my "googled" english :o

[Galaxy Tab 8.9 General] poisike:
As far as I know, AT&T uses different 3G frequencies then we use here in Europe, so the 3G won't work either.
[Galaxy Tab 8.9 General] Croak:
My replies in red.
[Galaxy Tab 8.9 General] Ikaro:
Thanks for your reply!! :)

In the AT&T web page, the specs about SGH-i957 AT&T say:

GSM/GPRS/EDGE: 850/900/1800/1900 MHz

HSPA+/HSPA: 850/1900/2100 MHz

while in the SAMSUNG italian web page, the specs about SGT 8.9 P7300 say:

GSM&EDGE Band	850 / 900 / 1800 / 1900

3G Band	850 / 900 / 1900 / 2100

The 3G frequencies are the same... right???

Max
[Galaxy Tab 8.9 General] Croak:
Right. It will work just fine on European GSM/UMTS/HSPA networks. Also, if you want to wait a few days, I think you will find that it is launching in several European countries very soon, starting with Norway.
[Galaxy Tab 8.9 General] poisike:
Here where I live we have:

HSPA in cities 2100mhz

HSPA outside cities 900mhz (because it has larger range then the higher frequency)

3G 1800mhz

I believe it is the same for most European countries. I personally would not buy a device that doesn't support HSPA on 900mhz.
[Galaxy Tab 8.9 General] Ikaro:
In Italian:

Ciao Croak, noi italiani siamo dovunque!! ;)

Grazie per aver risposto alle mie domande!!

Sarò pazzo ma ho intenzione di acquistare un SGH-i957 AT&T usato su ebay perchè ha la (CPU + GPU) più veloce del Tegra 2 del mio SGT 10.1 P7500.

In particolare mi interessa perchè con i video il Tegra 2 è pessimo, mentre la fluidità di TW + Honeycomb 3.2 è buona.

translated into English:

Hello croak, we Italians are everywhere! ;)

Thanks for answering my questions!

I'll be crazy but I'm going to purchase a SGH-i957 AT&T used on ebay because it has the (CPU + GPU) faster than the Tegra 2 of my SGT 10.1 P7500.

In particular I am interested because the videos with the Tegra 2 is very poor, but the fluidity of TW + Honeycomb 3.2 is good.

[Galaxy Tab 8.9 General] modestone:
I can say for sure that 1080p mkvs play great.

I have watched some 15+ gb 1080p mkv movies from my file server over wifi on the local LAN using bsplayer.
[Galaxy Tab 8.9 General] Ikaro:
Ok i checked (wikipedia and other italian web site):

In Italy 3G use 2100MHz (1920 - 1980MHz Uplink and 2110 - 2170MHz Downlink)

In Estonia 3G use 900/2100MHz

Max
[Galaxy Tab 8.9 General] Croak:
The MSM6660 in the Tab 8.9 LTE does support 900 UMTS, without a doubt.
[Galaxy Tab 8.9 General] poisike:
UMTS yes, but we don't have 900mhz UMTS here. We have UMTS at 1800mhz. HSPA at 900mhz and 2100mhz.
[Galaxy Tab 8.9 General] Croak:
UMTS/HSPA are interchangeable for the purposes of radios.

TLDR

THE AT&T TAB 8.9 LTE WILL WORK ON ALL EUROPEAN GSM/HSPA/UMTS DATA FREQUENCIES

Clear enough?
[Galaxy Tab 8.9 General] Ikaro:
Thanks poisike for the questions you raised about the UMTS frequencies, I had not thought :)

Wow Croak, we understand!!!! ;)

Many thanks modestone, your words are music to my ears :D

Max
[Galaxy Tab 8.9 General] poisike:
I don't want to argue with you but i'm afraid it is not true. I personally have used a device with the same radio specs as the AT&T Tab 8.9 and it doesn't give me HSPA internet connection outside cities where we use 900mhz for HSPA.

If the specs are true there > http://www.gsmarena.com/samsung_galaxy_tab_8_9_lte-4125.php then i'm sure this device would not give me HSPA connection outside cities (at least here in Estonia).

Samsung Galaxy Tab SGH-I957 ATT no 3G

Hi there, I just bought a Samsung Galaxy Tab SGH-I957 from ebay.I'm currently a ATT Customer and I have a 3g sim card with unlimited data plan.I already tried 26 times to get internet via 3g sim card but it won't work. I have also did the root process.Somebody said I need to unlock it but that makes no sense since I have a ATT sim card. Any advice will be highly appreciated.

AT&T Bloat Ware Delete

I made a list of all all the apps that I would consider bloat ware. One thing I noticed is that when I deleted "AT&T Communication Manager" I get constant FCs.

Why would this be? Is there a way to delete it without FCs or should it just be freezed?

Anyway here is the list:

AT&T Communication Manager (This may not be able to be deleted)

AT&T Code Scanner

AT&T Family Map

AT&T Navigator

Social Hub

My AT&T

Media Hub

Pulse

Qik

Yellow Pages

Zinio

Also these may be considered useless in my opinion:

Pen Memo

Memo

Messaging (I don't have a data plan for my tablet)

I would just freeze and not delete. Its safer.

I also find communication manager really useful (because i have a data plan).

SGH-i957 cm7?

I was watching a video today of CM7 working on a Nook Color and made me think.....maybe it would be possible to port the "Skyrocket" CyanogenMod 7.2.0 Alpha Version 4 to our device since it is somewhat similar. This would mean of course that we would also need a modified kernel though Da_g already has one for Skyrocket CM7. CM7 has a section under options just for tablets so in theory it seems like it would work to me, though I barely know sh*t from Shinola when it comes to some of this stuff. Maybe it could be a quick start for an alternate SGH- i957 ROM?
