[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
It seems to depend on the routers in your vicinity.

For example, I can stop my wifi from working by just switching on a Huawei E585 router, even when I am not connected to this router.

In one of the locations where I visit, there are a lot of wifi networks (over which I have no control, neighbours, etc) and my P6800 ics wifi will not work there, no matter what I do. I am obviously not connected to those networks.

At my house and my GF's house, the wifi works fine.

So it is possible that your wifi works perfectly in your locations, but that you still have the bug.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] niceashwin79:
yes brontetab you are right. in this case you have to go for either nexus or HTC. I feel they are unbeatable in their post purchase support.

if you will go for iphone then you will understand its issues. I have spent time with apple.

if someone want to learn from it's own mistake then it is their choice.

I just know android will survive for long enought until mozilla phone os comes out.

I can confirm now that flashing the HC firmware followed by its corresponding ICS firmware fixed the wifi issue I had earlier.

In my case I used the the Hong Kong (TGY) version on my Middle eastern tablet (XSG). One whole day now and not a single disconnect.

Here is what i did:

1- On current firmware, boot into recovery and wipe data factory reset

2- Flash the Hong Kong HC version using odin

3- After flashing finishes and system starts, reboot into recovery and make sure csc is TGY not multi csc (if not flash firmware again. In my case i had to flash again)

After this step you have 2 options:

either update to ICS using kies which will show that you have a firmware upgrade

or

4- Flash the Hong Kong ICS version using odin

5- After flashing finishes and system starts, reboot into recovery again and make sure csc is TGY (which it should be)

6- Reboot system and enjoy

I used the Hong Kong firmware coz I already had it downloaded, but I'm sure it will work with other countries.

Hope this helps...!

I also flashed my P6800 with ATO hc, and then with ATO Q2 ics.

So far so good, but I have not yet tested it with the E585 on, or at the difficult locations.

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] niceashwin79:
Qaliza...I will go to comparative stage...

I am using CWM6011 on my current CM10 i could not find such code while booting with recovery.

Later I restore system to my previously backedup honeycomb...there also same..

No such code applied message!

Does it has to do with recovery?

Do i revert back to system recovery?

Advise..

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] qaliza:
Oh yeah.. I was talking about the stock system recovery not CWM recovery.

Just flash the stock HC rom using odin, boot into recovery and it should be there..

Mind to share link for HC HK version 6800?

I' downloaded from sammobile, after flashing it says applied multi-CSC then applied TGY.

no OTA after this version, and even I go for ICS using Odin

still have wifi problem.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] niceashwin79:
Verusanti....

* I have used the same website to for download...http://www.hotfile.com/dl/145533083/3d46901/P6800ZSLA2_P6800ZZHLA2_TGY.zip.html

If you feel problem with your downloaded copy ..redownload it.

* Also no problem when it says that multi-CSC is applied ..what is more important is it- should apply TGY code before that.

If that happened means you are on correct path.

Please follow the line by line instructions provided by Qaliza, our senior member of xda forum above.

And enjoy stable wifi connection on your galaxy tab.

If you have any issues- you are free to contact.

For your information..i have to flash my HC and ICS rom sequence couple of times to achieve it.

Now it is working even after rooting. Absolutely fine.

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
OK, I have done extensive testing using this procedure to clear the P6800, install hc, and then to clear again, and install ics.

I tried it with the Open Austria and Hong Kong firmware (ie four firmware files).

My final attempt was to clear the tablet, install TGY 3.2, and then to clear again, and install ics via Kies.

I wasted an incredible amount of time and effort, and also a lot of mobile data.

Final Conclusion : IT DOES NOT WORK !

If your wifi works with ics, it is only temporary because you are in a simple environment at the moment.

My Hong Kong tablet is now dead standard, coming from hc 3.2 TGY to an update to ics 4.0.4 TGY via kies.

And the wifi still does not work.

The moment that I switch my Huawei E585 on the wifi dies, even when I am not connected to the E585 but to my normal router.

This is what happens when I am out and about, and I have no control over other people's routers !

Samsung, please fix this problem, this is the only way that this issue will be resolved !!!

can you try to use the Samsing Galaxy S / S2 / S3 CSC changer from the playstore?

Flash HC > Flash ICS > change CSC using app to the CSC of the ICS you just flashed
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
OK, I will have a look, but IMO the CSC is already correct (ie TGY). After all, it says so when you go into recovery mode, and Kies works, which it wouldn't if something was wrong.

I had the same wifi issue, extremely unstable WIFI.

Decided to try the newest ICS 4.0.4 from Vietnam (Updated on Nov 1st, 2012), directly installed using ODIN on top of the Brazil 4.0.4 one.

So far, everything looks great. Will drop a line tomorrow to let you know how the WIFI behaves.

I think I can pretty much confirm the WIFI issue is fixed in the new update in the Vietnum release (should be fixed in Singpore version as well) as both have:

Been using it for about 1 hour, the WIFI is so enjoyable. fast and reliable.

I have a Verizon Galaxy Tab 7.7 that I used for a year on Honeycomb 3.2 with no wifi issues at all.

A few weeks ago I flashed to ICS and started getting frequent wifi drops.

I then flashed back to Honeycomb 3.2 and the wifi drops have persisted since I flashed back to HC.

Has anyone else experienced wifi drops on HC after flashing ICS and then going back to HC ?

I have a model from Brazil and Samsung only released JB for this model for some Countries from Asia at this moment.I flashed this version anyway as I've been waiting this for a long time.

You have another option. You can try flashing only the modem from HC over the last Firmware you flashed. It may work to fix the wifi issue.

Note that the Verizon 7.7 is an almost totally different beast to the international models. Flashing a GT-6800 ROM to his tablet would surely create a brick. I'm not even sure if the modem firmware is on a separated partition on the Verizon tab (CDMA and LTE work very differently compared to GSM/HSPA).
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] mentox:
Hi All,

I think I have resolved the WiFi dropping with "Authentication Error" on my p6800. I am with stock 4.1.2 DXMD3, with stock kernel, fully wiped. When it drops I had to do the same: "...i need to either toggle wifi on/off, or sometime even reboot".

The problem was a setting on my router WiFi network, that only this device have issues with: Wireless (2.4 GHz): Channel Width - 40 MHz

When I switched that to 20 MHz, the problems disappeared, 2 days by now. My router is Asus n66u with Tomato 1.28 by Shibby, but the stock firmware of this and many other routers also have this option available. I guess this problem should be fixed inside the p6800 somehow, but for now I'm happy that I have managed to fix this for myself.

I hope this helps someone!

Thanks for posting suggestions guys! But reflashing rewiping redownloading is just a waste of time. Don't do it as I've tried it.
