Hello all,
My Galaxy S2 (international version) is having wifi issues after I installed the stable release of cyanogenmod 9, and after flashing my modem. I'm not sure exactly which of the two caused the problem, if either, as they both happened pretty close in time. I was also under the impression that the modem firmware didn't affect wifi.
What normally happens is that the wifi will work for a few minutes and then stop. Also, despite not downloading any data, it says it's connected and has an excellent signal.
Any thoughts on what might be causing the issue?

Probably it is incompatibilty with the CM9. CM9 stock modem is good enough IMO.

I just tried reinstalling CM9 and I'm still left with the modem I flashed. So apparently CM9 doesn't come with its own stock modem. Also, the problem didn't go away. Might there be a compatibility issue between modem and CSC?

Wifi issues are Kernel related and no modem related.

change your kernel. Your Wi-Fi will work fine afterwards

Hi,
Today I've installed the leaked version of Gingerbread on my Galaxy S but I'm having serious trouble with the modem. It barely ever gets a signal at all.
I've installed the KA7 modem and the signal is always stable.

hello fellow xdas
while back i had gotten my hands dirty with the CM10 project as i just couldn't wait for the official update! i learned quickly that i had serious problems with antenna/reception. i tried carious base bands (as recommended on forums) using GetRil/flash.Odin. this didnt seem to help, even though i would get better reception, my signal was unstable. In the process i tried other roms like JellyBam and had the same issue.
As this is my main phone and i do actually need to call with it, i went back to the stock rom i downloaded. but surprisingly i still have the same issue! GetRil also shows that i have incompatible RIL/baseband. this is what it shows:
RIL: I9100NELP2; I9100XXKI4
Baseband: I9100XXLPQ
FYI: i am located in the Netherlands and use T-mobile network.
so have i installed the wrong ROM or done something wrong in the process... ? does anyone have any experience with this? i much rather have CM10 but only if i can get to call normally once again?
thanks

Use either of the 2 links below to download either the NELP2 modem of the XXKI4 modem, and them flash them onto your phone via Recovery Mode. That should resolved your incompatible RIL issue.

thanks a lot zee54,
can i just go back to my CM10 or JellyBam, install the above mentioned radios and get everything working? or does it depend on the RIL which that ROM is running! I have tried a number of modems when i had CM10, but dont know if i tried those... i did try BVLP7 for sure
Based on this forum right here i need to have the I9100BOLPD ROM as stock for Netherlands T Mobile!

The modem is independent of the ROM, mate. So it wont make much of a difference whether you install the radio on stock firmware or on CM10. You could try using the modems mentioned by zee54 with CM10 and seeing if it helps. Also, give it about a day or so..since the phone tends to take a while to get 'used' to a new modem.

The unstable signal or "RIL Crash" as it it called isn't actually caused by having an incompatible RIL and Baseband (modem). It is a more complicated issue which I don't fully understand myself. But what I do know is that it currently affects all customs roms that are based on CM10 and use the CM Kernel. So switching modems might help recude the frequency of the problem but probably won't irradicate it completely.
You should not experiencing this problem if you go back to stock samsung firmware. If you experience problems you might want to do a full wipe (Data, Cache, Dalvic-cache) before reflashing and fix permissions afterwards.
On a more positive note, I have found that using the Siyah Kernel with your custom rom does seem to eliminate this problem, or at least reduce it occurance to such that I have not noticed it happening.
So personally i would suggest that if you wish to go back to CM10 or JellyBam ROMs, then do so but also install the latest Siyah Kernel for the S2 from here http://www.gokhanmoral.com/
(Here's the XDA Thread for the Siyah Kernel - [KERNEL] SiyahKernel v4.1.5 (v5.0a2))
I am currently running CM10 with the Siyah Kernel v5.0b2 and it is working very nicely
great stuff guys... 2x thanks for both of you!
Zeey54, i just had Siyah v5 Kernal installed, installing the latest JellyBam right now! so lets see what happens. i was suspecting that beside the RIL/baseband there were other factors as i did not see any significant difference between them. but then again i dont trust my judgement on such issues as my knowledge is quite limited.
will send an update with the result after installation in a few min.

installed the BOLP7 modem, overall reception is much better! data connectivity is also better and faster. but i still have some periods which my receptions drops and goes back up, seems like radio/modem crash (if im right). dont know if that is due to the kernel or modem or ...?
the reason i went for BOLP7 modem was because the latest official stock rom from t-mobile Netherlands was I9100BOLPM_I9100TNLLP8_I9100BOLP7, so i thought that would be the best one to try!
will wait a little more to see if this improves as the modem settles.
4th official ROM too much coverage you please make a review ?
need modem
First of all, thank you mate for your hardwork and awesome utility.
I have a Samsung galaxy S2 I9100G , recently flashed jelly bam custom rom. I am based in Saudi Arabia, the reception is not clear and people complain that it is switched off or out of network. I tried calling with another mobile and i got a response that my mobile is switched off, at the same time i checked my S2 mobile , it shows the full signal of the network in status bar.
what should i do? Which modem should i flash. the getRIL shows RIL/baseband is matching (I9100GDDLP5).
cheers

Ok, so ive had a couple of problems with my recently bought Sgs2, ive got all the other problems fixed except this one: when i turn on the camera app, the flash goes on and off once, the same happens when i turn off the camera. Its a very fast flash that occurs.. it doesnt matter what camera app i use, it does it everytime.. the flash does work properly during camera use if needed, and works normally as a torch.
It doesnt bother me much, but would be nice to get fixed..
Any ideas?
If your using a custom jb rom then it's normal. It's a known bug.

Im using SlimICS 4.2+ Siyah 5.0.1

Looks like he said: if its a custom JB rom, the bug occurs. Im using ICS and the same thing happened before i even flashed a custom rom. The phone was running a stock Samsung GB rom then..
"He" has a name
And if u said it happened before flashing roms, Then it must be a hardware issue.

I have the same problem, that the flash will light up shortly when the camera app closed, and when I read the last comments it seems that this is a known issue for quite a while.
How does it come that this is not fixed yet. I'm using custom roms now for a few month now and from the beginning I was wondering about the strange flash behaviour compared to the stock rom.
Is it because there is still no official release from Samsung for JB or why is it so difficult to fix? Are the camera drivers closed source?

have u tried flashing a Stock ICS rom (v4.0.3) and seen for the issue
if not give it a try and see, just to confirm whether its really a hardware issue or a software one
nothing to loose though, if the problem gets resolved for u it would be fine right
do a clean wipe before installing.

I used to get that on my x10i with certain roms.Definitely a software problem.
Same issue here, came about randomly day before yesterday. LED flashes once, quickly, whenever something tries to activate it.
Only ever used stock soft/firmware, and Chainfire's kernel. Cleared all caches, tried factory reset, problem persisted.
Flashed to whatever the latest ICS is for H3G today, problem still persists, I shall try official kernel tomorrow, see if that fixes it -- I don't hold much hope.

Hey guys,
I've been running various JB ROMS for a while, mainly Omega but now on Fox Hound. Ever since I went to a JB ROM my signal strength when using auto or WCDMA only network mode has been really bad. I only get good signal when using GSM only. Problem is data is pretty slow on GSM.
It seems that JB modems could be the problem so I've tried flashing various other JB modems and even some ICS versions, all have had very little effect.
Has anyone else experienced this problem with low signal, I'm tempted to flash back to an ICS rom

Just tried a few files from the thread but still not very good. Think I'll try an ICS ROM.
So my bro got a i9300 S3 (international), its his first android after iphones for years.
Anyway he has tried to install Cyanogenmod and reckons there is no wifi (will show his router but not connect)
Stock works fine but he hates touchwiz.
The steps he has taken are....
updates to 4.3 from Kies
rooted via odin
installed cwm
installed cm10.2 and gapps
He says everything is perfect except wifi, its sees router and saves connection but doesnt connect.
His baseband is i9300buugj3
Now he is really gutted as he loves the stock android look.
Any fixes and steps would be appreciated! (I cant get to him to have a look myself hence the post!)
Perhaps update baseband would fix?? (And if so how would he do that? Via odin? Does CWM being installed affect anything?
Thanks in advance!!

this happens sometimes, i m too using cyanogenmod myself, when i was using stock rom i was able to connect to my college's router, but after flashing cyanogenmod, i was not able to connect to it, nowdays they have replaced with new router, n there is no problem inn connecting to it, even i never had problem to connect to my home's router, this happens with some router.. maybe this time with your's.. try to connect to other router than your's.
I have the exact same problem
my phone sees the router and saves connection but doesnt connect.
I also tried Wifi tether from my other phone and even that doesnt connect, it just saves the network...
this is happening on all CM based 4.2.2 roms...
havent tried 4.3 and AOSP roms...
