wifi reconnects often - Galaxy S II Q&A, Help & Troubleshooting

hi guys
I have an issue with wifi , it keeps disconnecting/connecting from time to time which is pretty annoing especially in a game , not to mention on facebook for example.Currently I am on XWLPY 4.0.4 stock nordic but the problem also appeared on 4.0.4 ORO and the spanish Jelly Bean.A curios detail , I was at some friends for a few days and using their wifi the connection did not drop at all...so I believe that maybe my router is causing this , btw it's a TP-Link WR841N .
I tried several different wireless channels , assigned static ip to my phone but it keeps reconnecting ! And of course"keepwifi on during sleep" is at always.
Any advice would help.

Problem with network connection/data connection

Hello,
I am from romania i got i9100XXKL1 installed on my i9100 and i have problems switching between 2g and 3g and switching data on and off... i loose signal, then get in back but not in a manner that i can make use of it and finally have to restart the phone for it to work. Have any of you got this problem?
Do you have a solution?
Tried with the stock kl1 modem, and with kp8 both same problem.
Seems i have fixed the problem myself with a install of the i9100xxkp8 and a repartition.
If you have any idea to this problem please post it here. It would be gratelly apreciated.
I will update if anything changes.
You are aware i hope that KP8 is a test rom not released by Samsung it has bugs and as its not a released firmware it voids your warranty .
Suggest its the KP8 modem that has improved your problem or the simple factory reset .
jje
Don't know what fixed the problem had the problem also with kl1.... and kl1 is an official release.
I had installed the stock KL1 (fully: rom, kernel, modem) had the problem with that.
and the KP8 wich is a beta fixed it.

[Q] Cannot connect to 2G/H+/3G Internet

I have flashed this firm:-
XWKL1
Firmware info
PDA:XWKL1
PHONE: DDKL1
Date: 13/12/2011
Android 2.3.6
INU (India): http://www.multiupload.com/7K8FL86IEQ
XWKL1 Stock Kernel: http://www.multiupload.com/LSO4P572C9

with speedmod kernel.
(I should have flashed JPKJ2 gb 2.3.5 firmware, but because its outdated, flashed the kl1 2.3.6 instead)
My problem is that i cannot access the 2g or 3g internet. I have the jKay mod which turns the signal icons to green. but they dont. they just come on (grey) but dont connect.
I called the operator many times to install the settings. but still no help.
If anyone in uae, can u confirm theres a gb 2.3.6 for uae?
any advice?
I recently bought a samsung Galaxy Y, and this had 2.3.6 xxkk(?) firmware with arabic support. Can any UAE user confirm that there is a 2.3.6 official update for galaxy s2?

Check your APNs to see if they changed or got wiped out?

Yep, they are still there.
I installed new one by calling the helpline. they told me to restart my phone afterwards. i did, but still cannot connect.
Is it possible that marketenabler app is causing the problem? i know that when you switch sim ids (from local to US etc) u cannot connect 3g.
but even if i try to connect with local sim id it does not connect
Man, just Google for your provider apn details for android. As far as I know 3g etc should work the same on all firmwares unless your phone is not the international version.
I have the i9100t which has a different modem. When I flash any rom I reflash just the modem and all is good again. But first make sure your apn is correct and you have selected it (should have the green dot beside it).

Hi all,
First time poster, long time follower!!
I'm hoping someone can help me here because i have a real headache with my galaxy s2. I live in Rep. of Ireland.
When i got it at Christmas everything was perfect. But two weeks later i suddenly lost my 3g. Phone works fine on 2g (except for the slow speed), but i contacted my carrier 3Ireland and they said everything is fine on their end. My APN is perfect, i've tried toggling airplane mode, entering codes, data package checks. You name it and i've tried it.
When i force my phone to select 3g it looses all signal and i have to restart my phone and quickly go back into settings to choose 2g or i will loose signal again.
This is the following on my phone.
Android version 2.3.5
Baseband version I9100XXKI4
Kernel Version [email protected] #2
Build number GINGERBREAD.XWKI8
I've being reading about modem/radios lately, is that just the baseband? Could that be my problem. I'm a noob at this kinda thing.I just want my 3g to come back.
All help is greatly appreciated. Look forward to hearing from you all.
Thanks.

sxi200 makes an excellent point. Make sure what your model is - GT-I9100, GT-I9100G, GT-I9100T - it WILL make a difference.

Because I've flashed an international firmware, when the phone boots up it shows i9100 and in settings / about phone it also shows i9100.
The only place it shows as an i9100T is on the sticker under the battery. So remove the battery and check just in case.
EDIT: you say you flashed an Indian firmware. Aren't Indian models the i9100G. Maybe you need to flash the international firmware if you indeed have an international model.

Well, i did go back and flash the jpkj2 2.3.5. and still no connection.
will try from an open place again later.
i have an issue with my internet connection too. i got an I9100(international version) and things were perfect till i switched to 4.0.3 and since then, my internet just refuses to connect although i have full signal strength and 3G or H displayed. but there is nothing going through.
it works again after i switch to airplane mode and back. i have no issues with wifi.
i have tried many modems and roms. i am currently using the KI4 rom and it still gives me issues.
please help.
update on situation
Hi guys,
just an update on my situation. Had the phone sent to Samsung twice for a check and bothe times it came back perfect with test sheets showing all was perfect. I decided to have another check done on the phone and it now says that the phone is blocked!! What the hell!. When i checked first weeks ago all was good and now it says it's blocked, but i'm getting 2g signal, surely i should be getting nothing if it's barred.
I have no idea who the origional service provider was of the phone, is there any way of finding out who the origional provider was or is there any way of removing this barring?
Thanks

i9300 signal problem

Hello everyone I have a Samsung i9300 that keep losing signal.
While I have signal I get not registered on network, after I do airplane mode on and off i get signal back.This problem seems more happening when I have wifi activated. It is not software problem cause I did a deep clean and I am on 4.0.4
now but problem still persist?
What could be ? Should I replace wifi antenna, sim reader or what?
Thanks for any help
That is very old firmware .
Suggest update firmware see faqs and guides .
