Think the wifi might be flakey on mine. - Galaxy Tab 10.1 General

Looks like my Galaxy Tab 10.1 is having some odd wifi issues.
It started when I tethered with my Galaxy S Vibrant phone. After about 15 minutes the phone would freeze up and I'd lose network connectivity on the tablet. The mobile AP app is unresponsive and I have to reboot the phone.
I've tether other tablets and never had this problem. I tried a few times and the GT 10.1 froze up the phone every time after about 15 minutes. But tried again with my iPad and Nook Color and it didn't have any problems.
Then I get home and use my 802.11n router. And I start running into intermitten network connectivity drops. Market and other apps will sometimes give a "no network connection" message and ask me to Retry, which usually then works.
I also see the wifi icon turn from blue to gray sometimes.
Tried my 802.11g router as well, some deal. So I think it's something quirky with the wifi on my tablet.
PS. One thing I just realized. This only happens with apps that are running in the background. If I'm watching YouTube or I'm downloading apps from the Market, I never ad it give me a network error in the middle of this activity. But if I switch a background app, then it'll tell me no network connection.
Maybe I should do a factory reset first.

that is very weird, I have had my galaxy tab since the 8th (went to the NYC launch) and I have been tethering it to my thunderbolt with no problem.

On mine, default wifi setting was to turn off when screen off. I changed it to never.

It may just be a bad unit, mines been solid

Factor reset didn't help. And wifi policy is set to disconnect never.

Same thing happens to me. This is my 2nd unit. First one was fine. just traded out for the grey, but they both have the same issue. No issues when I'm tethered though.

[Q] Verizon 3G vs. WiFi (problem)

On my Xoom, Verizon 3G kicks WiFi butt. This shouldn't be.
I thought maybe it's the WiFi network(s) I have been connecting to, but I have sampled a variety of networks including my home network with a very strong signal.
Quite a few 'time outs'. Symptom really seems to be if the connect is idle for any length of time, it disconnects. I quite regularly have to do something ''twice', including in 3 different browsers, to push through to a new connection.
Any similar from other users, possible diagnosis's or solutions?
Thanks in Advance.
I think there might be issues with some access points and different tablets. I've heard of similar things with laptops and ipads as well.
The general consensus here however is that the xoom has the fastest wifi out of any tablet device. I don't have the link but I believe one of the review sites tested this.

Thanks for the reply. Further reseach shows its apparently a known issue and is being looked at, for example:
http://www.xoomforums.com/forum/motorola-xoom-help/317-connecting-through-wifi-issues.html
And likely root cause:

A temporary partial work around is to change the WiFi disconnect policy to the "When screen turns off" setting. you will get a delay of about 5 seconds when first connecting to the internet after unlock, but apparently the memory leak is cleared when you reconnect this way. Continual long term browsing will eventually choke up.
No can't say as I have had any wireless issues, other than not being able to tether to my phone, but that's the phone's problem, not my Xoom, stupid Samsung.

I have had the browser FC on me after long wifi browsing. So this bug may have leaked out without getting fixed. i have tried the 3g that much but i will tonight and see what happens.

Yes, that is one of the symptoms of the memory leak. We should see a fix eventually.

Love the eventuall lol. Yeah its not that big of a deal. Its worth it to be a first 3.0 user.
I've definitely experienced this as well. Wi-Fi disconnects and won't reconnect unless I reboot or manually turn off/on. Question, if I use the temp fix to change the Wi-Fi disconnect policy, doesn't that mean my 3G will be used and therefore my allotment of 1Gb / month will be eaten when not using the device due to background sync? Is there a way to turn off 3G as well?

Just turn 3g off... which is what I do, I will only have it on for road trips, ect.
Plus it will only use 3g if WiFi is not available.
Same issue
I had the same issue on my Xoom. Everything after long video streaming, the problem started and the video start to lag and eventually freezed.
If i try the turn off the wifi, it wil stuck at "turning off.........." forever untill i reboot it.

WLAN-connection hanging every 30 mins

I got my 7.7 yesterday. All is working great, but about every 30 minuttes of use, the WLAN-connection hangs. The WLAN-icon stays lit, but the tab is not able to send/receive data. To get it to work again, I have to disable WLAN and then enable again. It then works for about 30 more minuttes.
I have not installed any task-killers or battery-enhancers etc..
The router is a D-Link DIR 555. I use several PCs and Phones on the same router without losing connections ever. Encryption-type is WPA2.
Any ideas?
Bro here is the same problem really confusing me evrytime the wlan disconnects.
Have you checked that your WLAN settings do not put the tablet wifi to sleep ?
Settings -> Wireless and Networks -> Wi-Fi settings -> Wi-Fi sleep policy
I'm having the same problem here, and my wifi policy is set to never, so when that happens I have to turn off/on wifi.. not good!.
I have the LTE version, but am running it without a data plan. I have the same issue with WIFI. The connection will hang after 30min to an hour of use. It is VERY annoying. I ran Speedtest, and i get an interesting result, over wifi i get a very fast download speed (15+Mb/s) but my upload totally hangs. It just sits there. On the same wifi, with my Galaxy Nexus, i have no problem with download or upload.
I've seen several threads across the internet about the problem, and no one seems to really know why. Some people say you need to change settings in your router, and it isnt the Galaxy 7.7's fault, but, i don't know if I buy that. I have the same problem at the Airport, and, i cannot exactly go and change the router config there. I am hoping that there will be an update to the firmware for the wireless radio, either separate or with ICS.
WIFI Problems Solved!!!
Hi,
I had the annoying wifi problem. It would work really fast for a few minutes and decide to stop working all of a sudden.
I fixed the problem by setting the maximum Router output to 54mbps G. Seems like the galaxy tab 7.7 does not like the N settings.
Now it works flawlessly and I will just use it at G speeds until Samsung provides an update. (I really do not notice the difference in speeds between G and N. Just the peace of mind that it will work every time.)
I hope that solves some of the other users' problems.

A500 Disconnects from Hotspot connection every 12 mins

Hi, I'm having this problem with internet connection using the portable Wi-Fi hotspot on my Galaxy Nexus. My A500 connects without a hitch to the Nexus but after 12 mins (this happens after each connection),it disconnects then waits for about 20secs before establishing connection again. This can be annoying especially when streaming videos on the A500 which tends to result in starting the videos all over again ie after each disconnection.
What can i do to resolve this issue?
I'm on Stock Honeycomb 3.2.1 and not rooted. Thanks

are you sure it's not from the nexus the problem ?
I connect my tablet to my liquid metal I got disconnected only when the 3G goes down... but never the wifi.
check maybe setting wifi policy etc... maybe.
check your phone as well.
try another device I mean tablet to another device, another device to nexus...

The hotspot connection on GNexus seem to be active each time the internet connection on the A500 goes down. I've checked the wifi sleep policy on both devices. They are both set to "never (when on battery)". May be software on GNexus need to be updated in order for this issue to be resolved. I used to have an HTC Desire as a mobile hotspot device which worked though once A500 is inactive, the connection on the HTC ends.

im not sure exactly what one would be your best bet.. But on the phone. try d/loading a wifi/3g data usage and analyzer app. Something that can watch the data services and give a report on what is happening.
SORRY I cant give you a app name to try but i have not had any wifi/3g issues so not used one..
Good luck..
I have similar problem on my a500 . When I connect to my AP I usually get 4/5 bars but after some time without moving anywhere my signal drops slowly to 0 bars, tablet disconnects and reconnect after 1 sec with 4 bars. And so on... No idea how to fix that bug.
HOUSEM
That problem you speak about was an old HC bug...
the wifi drop
I got it, but on the version 3.2 that was resolved, and ACER released a kind of... patch about this year ago.
- Wifi work then when connect drop down to 0 and disconnect then try to reconnect... that was a problem from a file supplicant things. needed to be deleted.

I bet it's your phone software got a problem something like that. did you try to connect the tablet to another wifi and see how long stay connected...
my tablet is connected on a hotpot 24/7 nearly and got rarely disconnected.

The problem is,the connection on the phone is stable and everything that requires internet access on the GNexus seem to gain access to it. Also, when the tablet is connected to my home Wi-Fi, it never disconnects or drop signals. So, it seems the issue is between the A500 and the GNexus. Probably a software bug btw the hotspot on GNexus and the connection to A500 or the connections btw the two devices are incompatible due to one being on honeycomb and the other on ICS. Just my opinion anyway

Sounds like a nexus issue or setting.

You might be right about the GNEXUS cos when I was using an HTC Desire as a hotspot, there weren't any issues with connections. Probably, the next ics update for the GNEXUS might resolve the issue. Its a shame that I've already sold the HTC Desire.

Got simlar problem:
i use GNex hotspot to connect a tablet to internet (it's the tablet part of the Erisin EA779A car stereo) and after few minutes the tab gets disconnected.
i've tried to connect it to my old Nexus S usinf hotspot wifi and the connection seems to be stable
Both Galaxy Nexus and Nexus S have cyano9 nightly
I was wondering if the issue is just caused by a switch from 2,4ghz signal to 5ghz...
i have to try with another device connected to the phone to see if it drops

No WiFi in Play Store???

Hey everyone. I just recently picked up this tablet. Its the Verizon 4G version, but 4G isnt active right now so Im using WiFi only.
I can connect to wifi no problem, but as soon as I launch the play store the wifi drops. If I exit, go into the settings for the play store, etc... WiFi turns back on.
Any ideas?
Anyone? Ive noticed now that it seems to be happening using browser or opera too. Last night I powered te tablet off, rebooted my router and fired the tablet back up and it seemed to work for a bit. Im not too keen on having to do this each time, however.
Haven't experienced this at all. Try a wipe? Clear play store data? <-- doubt that would help but who knows.
Well the fact that its extended beyond the play store and into browsers bugs me.
I performed a wipe - no success. I started googling galaxy tab wireless issues and there are posts everywhere, but most were for the 10.1 tab it seems.
Interestingly enough, if I switch to 5GHz on my dual band router, it seems to work fine... but the 5GHz signal is so weak that the tab randomly drops it. It seems to be the 2.4GHz band that being a pain in the neck.
Interestingly enough, my old iPad has no issues with either band in any applications.
Wifi Issue
I just received my galaxy tab7.7 2 days ago and it seems that I'm also having the same problem. After reading online I realised that certain routers don't work well with it. I am not sure about the exact problem but next day I connected my tab to university network and it worked absolutely fine. I don't know if there are certain models which are having this problem or if all 3G versions have this issue. But I may write it up to samsung later to find out more. You can download an app e.g, Speedtest.net from google market and check if your network does work with it or not.
I use intel my-wifi to connect it to my laptop's network, it works fine for first few minutes but then my-wifi shows that tab isn't connect to it anymore whereas my tab shows it's connected to the inernet but doesn't open any page, email etc.
no such behavior from my tablet in last 45 days or so .
try factory setting ....

N7 won't connect to wi-fi after I wake it up after a while

Hi I've got problem with my N7 and maybe anyone else experienced it and have some solutions to this ?
After not using my N7 for little longer when I try to wake it up it doesn't connect to wi-fi automatically. I mean the wi-fi icon is there and wi-fi is ON but the icon is grey. I have to turn the wi-fi off and on in settings then icon in right upper corner of the screen gets blue again and I can browse internet etc.
It's not really a big deal but it can be frustrating sometimes, especially when you wait ages for page to load and then you realize that wi-fi is dead again.
I've got my N7 only two days but this already happened like 5 times.
Got other devices that connect to the same router and they are all working fine. HTC HD7, Nitendo 3DS, Acer Laptop, PS3.
Using D-Link router with WPA-Personal WPA-2 Only security settings.
Any idea how to fix this ?

Mine is grey as well after waking, but I can browse just fine with the Grey icon... No idea why.

No problem here with Linksys WRT54GS running OpenWRT firmware and also my phone's hotspot. It's probably the crappy firmware in your Dlink access point router. Try a newer version from Dlink or try an alternative from OpenWRT, Tomato, etc.
I've got latest firmware on my router.
Tried to change settings in my N7 with static IP but that didn't helped either.
same issue here
I have the same problem on my N7. It's the same whether I'm using it on my Airport Extreme or wrt54g.
Wake from sleep, see WiFi status icon all gray, no internet access. Turn WiFi off then on, reconnects and I'm on my way. Very annoying after the 50th+ time.
Mine wakes up in airplane mode and I have to press the power button to turn airplane mode off.
When the wifi icon is grey, it just mean that you´re not connected to Google Servers, but you can still use the internet.
When it connect to google servers the icon turns blue.
And i think that when the screen goes off it disconnect from google servers, and then it try to connect again when the device is waked up.
I did not know that. I learned something new today!
Bit ot, what about the bluetooth icon? Most of the time it is gray connected with tablet talk. Sometimes blue? Really thought the icons just did not refresh right away.
