[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Graz:
I think I have this figured out...

Update #4 (and hopefully the final update)

- Everything in the above updates was a waste of time.

- Have two APs in my apartment, so I disabled wifi on one of them...problem solved

- Did wipe/factory restore to remove all previous AP config info from Settings & removed the WiFix and Wifi Manager...wifi still working with no drops

Might explain why some had no problems with wifi on ICS, and others (like myself) have had nothing but problems. Also may explain why some folks have no problems at work or in some public places, but they come home & have connection issues.

Bottom line... Does your home have multiple AP's like mine does? Try turning all of them off except one, or disable wifi on all except one!

Want to say though that this is still not a fix! There's still a problem here! I have many devices in my home that have happily co-existed with multiple APs in my apartment and that includes my 7.7 with HC! No other device in my home has ever had a problem with both AP's wifi active & issuing IP addresses.

Part of this that I still can't explain is that the tablet can see other AP's in nearby apartments...some with reasonably strong signal strength...but these don't seem to be a problem.

Hopefully someone gets something useful from this...from what I can tell, this release of ICS has some problems negotiating wifi connection in the presence of multiple AP's...at this point, this is the best I can gather from all of this.

As before, I'll update if anything changes...

I am now also having problems with WiFi.

Since Austria ICS firmware was released and flashed I have no WiFi problems but just today it started acting weird, it just turns on-off in and endless loop. The only workaround i found to fix this is enable-disable Airplane mode.

I'm hoping flashing the HK ICS firmware will fix this as it is pretty annoying.

Am certain by using rotour wifi extender it would and will overcome wifi's issues anyday anytime ,and it's cheap to buy ,yes this isn't right

Nor fair from samsung support dev. Team but at least it's the best solution available

This should through a big quesrion . Why would it work through extender while it got nothing to do with frequency nor tx mode
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] radjeshsitaram:
There is no google app that can solve this issue nor is there an setting in your router that can solve this.

When the bug manifests, wifi module in tablet stops recieving.

Doesnt matter if u extend the range of your router 10000000000000 times or change any channel.

Maybe some people got it to work after changing a setting, it's just luck then wich might make it look like it got solved.

Without kidding after screwing around a whole week with this issue i told my tablet i would kill it and from that moment the problem was gone, it worked for 1 whole week.

Trust me it was not because i told my tablet i would kill it, it was just coinsidence, same if it all of the sudden starts working after changing a setting in your router.

The problem will get back, just like it got back on my tablet. I told my tablet a zillion more times i would kill him, i even told the tablet i would kill the S out of Amsung and even holded it out of the window, treatening to let it go but it didnt work this time.

Only thing worked was going back to HC.

I never blamed or yelled at samsung that ICS took forever to get released, i really DO blame them for not even letting know they are working on a fix. A problem like this should get fixed asap.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] brontetab:
Its bs. This is not a solution. The bug is in ics code
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] SrMoure:
It seems the issue is related to the modem version which comes with ICS. I read it's happening with HK and Austrian versions. Also read there is a HK ICS v2 but some people are still having issues with wifi.

My recommendation is for all those who upgraded to ICS, is to flashback the whole HC ROM and then only upgrade to ICS the PDA and CSC, but not the modem.

I did the process using mobile odin and i was able to remove the modem when updated to ICS (I have a P6800 HK , and upgraded to Austrian ICS without including the modem which is still the original version which came with the tablet). I didn't do a factory reset, but deleted the data of some apps just in case.

Hope this helps to solve the wi-fi issues.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Astrix Ashburn:
What your observation. Did it fix the issue or any changes/imprivement so far using HC modem? If yes, it easily can extract the HC modem and flash it with mobile odin.

TIA waiting for your feedback
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] cougarmaster:
Hi all,

I am using a HK version unrooted. I got my wifi working and is so far not giving me any problems atm. First time i flashed to the austrian version but wifi would just keep disconnecting keeps on turning on and off in rapid session. Then I flashed back to HC and everything was fine. Made sure everything hardware wise was functioning properly. Then I couldn't stand since I got ud to ics i just had to find a way to do it. Initially i used mobile odin to do the fashing but modem seemd to have many problems. Then i started to use desktop oding 1.85 at first then changed to 1.87(not sure i it makes any difference) I download the HK ics version and flashed it but then it had the same exact problem as the austrian version, but it was better since it could connect to my hone router. Then I was frustrated and just kept on flashing and got my partition all messed up so had to find a pit file to recorrect it. Then flashed HC then using keis upgraded to ics and wifi was way much better and stable but still had disconnecting problems., at least it was connecting to most wifi and no rapid on off. Frustrated still commited (gave a call to samsung and gave them a piece of my mind) I pushed the file toall section clicked on repart (which i had to use the pit file again later) and still had problems. Wiped the slate clean extracted the modem bin from the ics and just put the rest iin pda and modem.bin in phone and it work for me so far. Hope someone might make sense of this. So far really enjoying it and very happy.

PS: Not sure but make sure you wipe all data and cache as it. Solved many boot loop problems and jerkiness.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] CK563:
So much horror stories.

Mine, also a HK P6800, was actually working quite all right for the past month. But in the last two days it started dropping again.

I want to see how many of you, who have issues with this, have two routers at home.

This morning, when it detected two routers (with known passwords), it could not connect. The wifi flipped between on and off as stated by another poser. After I turned on my third router, a 3G mifi, it then suddenly connected to one of them. And this is the second time I observed such behavior.

Hopefully it will stay connect for a long time this round.

It blows my mind why sammy would just not fix it. They r so focused on the next big product and totaly forget about those who bought sammytabs just few months back. This leads me to think for all the advantages of high end product by sammy we still dont get to use the full power of our tab because sw is so badly done. Is it really worth wasting money on half finished products by sammy? I am starting to wonder....

If you can borrow huawei ws320 extender just use it and see how things going on! , 3 devices here having similar wifi issues all gone through extender connection . software fixes for no appearant reasons they might stop working after sometime, very weird.

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Steve_max:
Actually, it's not. I have the same problems using either the Austrian (ICS) modem or the Brazilian (HC) one. Also, the modem doesn't touch the wifi, that part is handled directly by the kernel.

You can flash just the modem instead of going back to HC, but again, it doesn't help.

The problem is that the WiFi problems happen only in some situations, and we still couldn't make sense of what exactly are the factors. My tablet works flawlessly at home (using a TP-Link 1043 router, b/g/n at 2.4GHz, WPA2), but at work (huge corporate network, with I-don't-know-how-many routers of different brands all working under a single SSID, no encryption, login through an HTTP nag screen) I can't keep it connected for more than 10 minutes. When it disconnects, it keeps seeing the network but can't reconnect. Goes through on-and-off loops. Rebooting and/or powering down sometimes help. I'll try to make sense of a logcat at some point over the next few weeks, but I don't have much hope. There is something terribly wrong with Samsung's WiFi drivers, and WiFi drivers are above my current debugging skills.

In my case, changing the modem wouldn't help. And I'd be impressed if it did, because the modem has no contact with the WiFi chip whatsoever. If it does, then there is something wrong with the interaction between 3G and WiFi, which also doesn't seem likely (mine doesn't work even with the 3G radio turned off).
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] regius:
I just found this thread and want to add my tab to the list of wifi issuses. HK 6800, rooted, with stock. ICS. It would connect to my home router (linksys 4200 and stay connected, but it would drop connection randomly on other routers. Disabling and enabling wifi works for me, and sometimes it would stay connected for a long time, sometimes it would drop connection after 10 mins. Never had any issues with HC.

I really dont know but i was about to give up so i was ready to thrash my tab by reflashing the pit file from sammobile which actually thrashed it. Then i found another pit file which rectified it. Then from there i flash straight from the ics rom and it worked. I redid this again and no problems. Still works extremely well. Had a reboot today by itself. Wifi works great. Not rooted. No straight answers but i am really happy is working.

Hi everybody,

It seems everyone is talking wifi drop problem of P6800. How about P6810 Hong Kong verson? My case is:

- connecting to Home wireless router seems stable. Seldom getting wifi disconnect.

- connecting to Public wifi hotspot (such as Mc Donald and Starbucks) has no luck. Never connect successfully. Login menu never pop up!!!

Anyone facing similar problems? Any solution in this case?

Yep, I have installed it and I still hve rhw WiFi droping issue.

Anyway I've been testing and I found that i normally lose the WiFi connwction when the battery reaches certain level (like 70% or 60%) but if I keep using the tablet to read offline, after the battery level drops 10% more the WiFi starts to work again.

Have anybody else experienced something like that?

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] guho:
I never had any wifi trouble on my p6800 ICS until i checked into the Traders hotel in Kuala Lumpur. The wifi there is weak and has something to trigger the bug. Wifi disconnecting, cycling on/off, i have seen it all there. Outside the hotel back to normal. I have done full wipes and installed austria and hk versions of the latest stock roms to no avail.

In the presence of this signal, even connecting to other access points no longer works. I found it interesting that the mere presence of the hotel wifi triggers the bug even when not connecting to it.

I hope someone from Samsung reads this and tries wifi and can reproduce the issue so there could be hope of getting this fixed.

Too bad, was going to give it a try.

It does not make sense but it's repeatable. Every time after wifi dropped, the tab won't connect until I turned on my portable 3G/wifi router. It's absolutely weird. But it worked every single time!
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] 九千.:
Talking about weird experience, nothing is more weird than mine.

The tab could connect the my home AP if I turned on the WiFi in tab before I entering the house.

But the tab could not find or connect to my home AP if I turned on WiFi in Tab AFTER I entering the house.

If I forgot to turn the WiFi on before I entering the house, the bloody tab cannot see my AP for the rest of night no matter how many times I go back and forth of the door.

So I left the WiFi on all day....this is just stupid.

Wifi drop on, and off.

Well, I thought I had lost the Wifi bug, but no its back with the LQ2 Austria ICS firmware.

All was going well for the past couple of weeks, then I used a cache cleaner and bam it's wiped something the Wifi uses.

Now I can't even connect to any Wifi networks.

If was doing the on, off Wifi but I fixed that with a reset.

Now even if I see the network it just won't connect.

I tried Wifi Fixer but that doesn't even help now.

Well, i have the same feeling, I'm on HC now and I endup in use it... In compares with ICS is far more aimed to tablets so except the fact that launcher is slow, everything is working as it should... I can do my job, it's easy have confcalls, in the same time to search the e-mails and the web, the cameras are good eough... i have a SDHC class 10 32 GB and I can see the movies with subtitles easily... All in one, i have nothing to complain abut HC... WHY ICS? because it exist, rather than that...I don't know...give me some arguments to upgrade to ICS... and see if they are worth the effort...

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] niceashwin79:
I will say it is faster compare to HC which you also agreed and ICS has better interface than HC but life is simple and sweet in HC.

So better I should be following you in that untill they were 100% sure that ICS is working with P6800.

Most of the people I communicate have problems with ICS, they were just upgrading because of UI and others telling ICS faster that is why.

But my attempt with HC also failed. The RAM which i downloaded has bug. My tablet keep booting all the time. Just keeps blinking Samsung logo then restarts again.

Please send me link of HC which you have. If you have downloaded from any of the site. Also give me your Kenel spec so that i will download it from Sammobile.

Enjoy!

Well, not exactly a solution, but the latest CM10 from locerra seems to be WiFi-bug free. At work, where on stock ICS my WiFi would disconnect after few minutes and lose connectivity, showing "not in range" or "saved" but never connect again until some dark magic tricks were made (usually involving rebooting, turning the tablet on/off, turning WiFi on/off, turning airplane mode on/off and/or running WiFix), I haven't had a single disconnect today. In my experience, the WiFi from CM10 (dated 03/Sep/2012) seems to be as stable as on HC. Might be worth a shot for those who don't mind losing some stock niceties.

You should clear data (factory reset) on CWM. If you don't, some ICS files will remain on your device and you will have bootloops.

Hi, Iam from HK and I got my GT7.7 on 1st Sep, 2012.

The tab came with ICS and I found wifi drops with my apple airport extreme seriously.

Then, I change the router to tp-link1043nd. The wifi connection becomes very stable.

The main difference between the two routers is dualband vs single band.

I think the problem is that the dualband router keeps GN7.7 to switch between the two bandwidths and keeps on and off of the signal.

I didn't do any wipe nor rom flashing.

And just change my router and I am now enjoying my GN7.7.

Just a pity that my cool airport extreme is now inside my drawer....

I won't test this build.

I'm using the latest CM10 build and the wifi works great. On the last week I only had two disconnections caused by a soft reboot. Other than the memory leak (that causes the soft reboot) I don't have any problem with CM10 and the wifi.

Hopefully Samsung have fixed the wifi bug and I will go back to the stock firmware, until then I will use the CM10.
