[Q] Galaxy Tab 7.7 WiFI connection issues (HELP) - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

After using for quite a whille my Tab 7.7 has stopped working. It searches WiFi, but after numerous tries to connect it with the router it says only "connecting..." and then "..saved, secured with WPA" and there is no internet.
Model: GT-P6800
Android ver 4.0.4
Baseband ver: P6800XXLPW
Tried several times resetting to factory data etc...no help.
What is wrong? Any help would be appreciated....Thanks

Maybe it's the router?
Reboot it and then device.
If still not working, "forget" the connection and re-enter the connection/password and connect.
Also try on a different router to rule that out.

XXLPW is the modem version. you're probably on one of the first ICS, XXLQ1 or XXLQ2. Those versions had severe Wi-Fi performance issues. Upgrade to one of the newer ICSs, or to the just-released JB.

You can download the ROMs at:
http://samsung-updates.com/device/?id=GT-P6800
The XSP (Singapore) Jelly Bean seems to be the most popular right now, it's very low on bloatware (I haven't installed it yet, downloading right now). Of the newest ICSs, the most recent clean ROMs were the SER (Russia) and ZTO (Brazil).
A good guide on how to flash is at:
http://forum.xda-developers.com/showthread.php?t=1469635
(read and understand it all before you start... The process is simple and easy, and the chance of something going wrong is minimal; but in the off case something goes wrong, you should know what to do)

tried today using different router, the Tab works fine, so seems it is the router problem. Will try to upload the last SER version later this week...Thanks

The router is not the problem, trust me. The early ICS firmwares had problems in some wireless networks; that didn't happen on Honeycomb, or on most Cyanogenmod builds, or on newer ICSs. The Wi-fi driver seems to be the problem, it had some incompatibilities with routers that work with every other device; that was fixed later.

Wifi driver problem
Hi to all Tab 7.7 lovers/addicts,
I have the same WIFI connection problem as described above using an official Samsung release Android 4.1.2 (Singapore) on my Tab 7.7 in combination with my new router (a Fritzbox)
With other routers/ AP 's I am able to establish a WIFI connection, but speed is extremely low. - it takes hours to load a simple webpage compared to Android 3.2 versions of the same tab 7.7 -, so this is not a hardware issue; . My conclusion : there is a major WIFI (driver ?) problem after upgrading Android (from original/factory installed Android 3.2 version to ICS and higher).
Is there a safe way to roll back my device to 3.2 ? Is it better to try Android 5?
Possible to use a seperate WIFI driver/bug fix ?
Thanks !

differences in LQ2 and LP5

hi all.. I started on HC...
then to LQ1
then LQ2,
now I see LP5..
Can you say what are the differences?
Should I flash again?
I'm in the USA.
thanks.alot
XALQ1 first released ics for austria... XXLQ2 is an update to it... they fixed something... but dont have any log on what they fix...
ZSLP7 release for HK. did not have face unlock
DDLP5 is indian release version. dont really have any different with LQ2
OK.. thanks alot
I also moved from XXLQ2 to DDLP5.
This was a mistake, no improvements and if anything the wifi problem is even worse under DDLP5.
I wish Samsung would fix the wifi issue, it is a major problem for me.
Lacks copy paste option on many apps...talk qq, firefox. ..., while those were working fine on LQ2 rom

i dont seem to facing any of the problem that you guys have... lucky me...
Just reflashed back to XXLQ2.
Wifi semi-operational again. More not working than working, but what can you do ?
Samsung could do much better if they started fixing their software, not sure if I could recommend these tablets to anyone that I know.
That said, the P6800 hardware is excellent - but I need a fully functional Jelly Bean software release !!!
BTW, is there a limit on the number of these Odin 1.85 flashes that one can do ?

Hmm, not too sure I've never had any problems with WiFi..
I gets the signal, and connects fine, LQ1 LQ2, and DDLP5
But I was with LQ1 previously and when I traveled abroad, mine could not connect to the most of WiFis even when GS2 connected just fine..
(on the way back home at airport, I fleshed to one of the CM9 Jellybean 1.3v and paranodroid, (see the devel forum), but still had the WiFi problem connecting to airport WiFi...
when I got back home, I fleshed to LQ2 and also DDLP5, they all worked fine (but of course only tested with my home WiFi..)
But when I fleshed this time, one thing I did was to really wipe Everything using cwm v6.0.01, (formating /system, /sdcard as well) except the external_sdcard.
My 6800 is hk version, whats yours? try fully wiping everything and flesh to DDLP5 ? I think the DDLP5 feels a bit smoother..
cheers

I ordered my tablet from HK, but not sure that it is HK version, how do you tell ?
I have had wifi problems with LQ1, LQ2 and LP5.
But it seems to be more of an issue when there is more than one router around - so it does not always happen. But it never happened with HC.

I have also faced same problem with Wifi so back to honeycomb it is bit slow but better than annoying wifi dropping issue with ICS.
some say after clearing data and factory reset this problem solves but not happened in my case!

it take alot of nerve to do a factory reset with these babies.. not a lot of safe kernels available.... only 1 really

I use LP5 and luckily for me i have no issue (wifi works fine, performance with antutu benchmark (6194) is good compared with LQ1 AND LQ2 -no overclock). I did factory data reset as well as using this (https://play.google.com/store/apps/details?id=com.manniakk.cscselector&feature=search_result) to enable my kies identify the device. I am using recovery from locerra (http://forum.xda-developers.com/showthread.php?t=1542897). The only boot loop happen when i want to do supercharge v6. Perhaps, i slipped up the procedure. No dare to repeat again.
Using locerra's cwm should be safe for a factory reset as it uses a safe kernel. Note that recovery has its own modified kernel that is used for the various operations. It does not use the rom's running kernel on the 7.7.

Hi Ashwin,
Can I flash a different country's ROM on my tab 7.7 (saudi / middle east) as ICS is officially still not available for the middle east. Are the firmwares available on sammobile & samsung-updates dot com genuine and risk free ? If yes, then how do I flash it on the tablet.
Sorry for the questions, still a newbie

P6200XXLQ2 - new Open Austria base

Changelog bere : small changes , increase battery life and more fluid system.
Are there any bugs present or observed? Is 3G working well even if it's not your region? LQ1 works fine even if it's not my region. Thanks again.
Installed this one with Odin. Just one question the baseband still shows as P6200XXLQ1 even though Kernel is 3.0.15-P6200LQ2 and Build Number is IMM76D.XXLQ2.
Is it normal for Baseband version to still show P6200XXLQ1 or have I made an error somewhere?
I decided to flash the Philippines(SUN)(August) because it's my region and it's newer than the Open Austria firmware(July). I have to say it has better battery life. Performance wise, it got a little better based from the quadrant scores I took. Higher overall scores than LQ1 and system feels a bit more faster. Although one time, System UI forced closed for no apparent reason and it lagged so much before that but it's gone now. I have no idea what caused that.
Does your Baseband Version still show P6200XXLQ1 ?
Problems with 3G
Installed this ROM a few days ago. Everything worked well except 3G. Voice calls and SMS also worked. After a failed automatic configuration of the APN, I set it manually but without success.
So, I downgraded it to the original HC 3.2. and wait the official update for my region (Romania).

Had someone experienced problems with 3G ?
After flashing P6200 XXLQ2 everything works OK but not 3G. The SIM card is recognised, voice calls and SMS can be sent/received. All APN settings are correct.
Can someone give me a suggestion?

download the stock honeycomb and flash MODEM_P6200LVJKL4_REV_04_CL1089917.tar using Odin... should get your 3g back
Works Fine
Everything works absolutely fine.. including 3g..
i dont notice any difference from the previous version in terms of performance or battery life. im talking about real world experience, not benchmark wise.
ENJOY..
It doesnt seem to be a MUST UPGRADE.
Hope it helps..
cheers.

hey pal, after the update, is your tab still unlocked? just curious because it's a carrier tailored version. i want to upgrade my open austria to globe's firmware, too.
oh, and if it doesn't have a carrier (in parentheses) beside the Country/Carrier, that would mean that it's unlocked, yes?
oh, and after this update, if you're int he philippines, will kies work? i bought my unit in HK, so i'm curious if it's because of the austrian rom that i'm getting an error from kies saying that my device does not support upgrading via kies. is it in order for me to upgrade via kies, i need to install the HK version again?
Now, that's a lot of questions. Sorry and thank you so much for the answers!

It is still unlocked. Do note that I'm using the SUN version, I think using Globe's or Smart's firmware will lock it, not sure. I am a SUN user but I tried a Smart Sim and it worked fine.
I did not see a Philippine ICS firmware without a carrier name on sammy.
Kies works here in the Philippines. It says it is the latest firmware.

No. I tested here in my Brazilian model, and no.
WiFi is very unstable.
And, being a WiFi-only tablet, this is a deal breaker.
Damn... no CM9, CM10, official firmware... I just can't upgrade from HoneyComb :crying:
I am didn't have any problem with wifi and this firmware.

The main problem is with hidden SSIDs. It's unstable and sometimes connect, sometimes don't
I had to reconfigure my router to get it working.
In Android 3.2 the problem didn't exist.
Samsung's fault. CM9 and CM10 ports have the same problem because of that.
Strange, on my Tablet was alright

Wifi not working...

Hello!
I decided recently to get a custom rom and since I've before used CM, I chose to use it yet again.
Though, I have problems with the Wifi. It's not working at all, it finds the networks though it just tries to connect and then fails.
I've tried the different kernels and searched through the forums for any solutions for it and I've tried what I've found, though nothing has worked so far..
So is there anyone that has had similar problem that has a solution for it?
I'm currently using,
[ALPHA][ROM][4.1.2] CyanogenMod 10 for Samsung Galaxy SL - Alpha 4 - Farewell Release
[UPDATE_4][9th Feb][KERNEL][CM9/CM10][ICS/JB] ALPHA11 Kernel

Hi,
I also had wifi problems similar to yours until I came across this simple solution.
You may have already tried this, but if not:
In Settings->Wifi->Menu->Advanced, find the option which says "Avoid Poor Connections" and uncheck it. (de-select).
This trick completely solved my wifi problem.
I hope it works for you.
check you phone mac address. if your router is filtering mac turn on. than u will not get connected.

could you explain in more detail how to flash nicsptl update.
which kernel has better battery qwerty or nicsptl update and with what governer ??
I've installed XXKPE and DDFL now and it's all working, almost like normal.
It's just my wireless signal that's a little weaker compared to before.
I have to be quite close to the wireless router to get decent signal otherwise I get almost none at all.
Is there any kernel or something I can do to fix this?

WIFI Weak on LOLLIPOP

Hi
I have a very annoying issue regarding WiFi. After flashing any custom kernel (Ak, furnace...), my wifi speed turns very very slow, it drops from 40 mbs to 2 mbs.
And the only way to fix it is with this app: https://play.google.com/store/apps/details?id=com.brilliapps.wifiandmorefixer&hl=es
As i said this happens after a kernel change. I changed thing on my router, like channel, security protocols, qos but no way, it´s not a router problem.
Also i restored the phone to stock ( including a bootloader relock, etc...)
Anyone else have this issue? How can i fix it permanently?
Thank you

First of all thanks for this great rom. Since the begining of the year, with the new radio my wi-fi reception is very weak, if I'm farer than 4 o 5 metres from the router my wi-fi disconect. I've tried everything, different roms, kernels, clean installs from 44s strock without luck. It works fine with 4.4. My security protocol is WPA2-Personal.
Now I've done a clean install from stock 44s to today release following the instruction, everything is great except wi-fi.

I have the same problem as you. the only solution i found is to use 5GHz band.
On blisspop builds (cm12 based roms also) older than 01/01/2015 i was able to fix that problem by using this tool: https://play.google.com/store/apps/details?id=com.brilliapps.wifiandmorefixer&hl=es
but on the newer builds it does not work. i think it may be some firmware related thing or something cm12 changed.
I have a thread open for it here: http://forum.xda-developers.com/oneplus-one/help/wifi-extremely-slow-kernel-flash-t2978780
And please, could some experienced dev tell us whats going on?
Solved:
The issue seems to be solved for now.
What i did was resetting the phone to color OS stock Rom and then flashed back my actual lollipop ROM.

Anyone else have this issue? How can i fix it permanently?
Thank you

WOW ! INCREDIBLE !! I even went through the Technical Support, they replaced my device and still had the issue. I used this application and it works !! Went from 1-2mbps speedest to my full connection : 28 MBPS ! Using CM12.0S latest official CM ROM as today
