[Q] No WiFi after flash. - AT&T Samsung Galaxy S II SGH-I777

Been looking for a solution for the past 12 hours and have not found any.
Bought a stock i777 with 2.3.4, flashed with SGH-I777_ClockworkMod-Recovery_5.0.2.3 and a stock 2.3.5 AT&T ROM. After ANY kernel is flashed, I seem to lose WiFi capability. I have 5 wireless points near my house and it just gets stuck on "Scanning" and then the WiFi turns off. No points are even listed!
Currently running CW 5.0.2.3 kernel, 2.3.5 AT&T stock ROM, UCKJ1 baseband, kernel 2.6.35.7.
TL-DR - Flashed and lost wifi ability.

Which 2.3.5 ATT stock rom is this that you're referring to? Have a link to where you got it from?

I believe I got it from here: androidadvices.com/update-samsung-galaxy-s2-i777-gingerbread-235-firmware/

Did it work initially when you went to 2.3.5? You said you've tried some different kernels, at what point did you notice the wifi broke?

I even reflashed using kernel + non-rooted system package located in this thread: http://forum.xda-developers.com/showthread.php?t=1286432
Still no WiFi showing. Just says "scanning" then the wifi shuts off.

Update: Flashed Entropy512's stock package + nonrooted with no luck. No wifi. Flashed zetamax kernel after. Still no wifi.
Showed at that time: version 2.3.4, 1777UCKH7 baseband, 2.6.35.7_ZedomaxStockKernel.
Flashed again with a I777UCKJ1 2.3.5 ODIN package that I know will fix the WiFi. It shows version 2.3.5, 1777UCKJ1 baseband, 2.6.35.7 kernel.
Seems like if I flash ANYTHING else besides this the wifi stops working on me.

Solved problems for myself.
Completely unrooted, reflashed ATTGalaxyS2Unroot_SGH-i777.tar. This brought me back to the original AT&T firmware that came with the phone. I then flashed SGH-I777_ClockworkMod-Recovery_5.0.2.3.tar and subsequently used SuperOneClick 2.2 to root.
WiFi seems to be working fine now. I am now running a stock 2.3.4 ROM, UCKJ1, kernel 2.6.35.7...Clockworks version.
If anyone else is having the same issue this should help.

Thanks for the updates. Sounds like a frustrating battle. Glad all is well.

Hrrrrm Having the same issues and the only way I could manage wifi to get back on was going to 2.3.5 which had it's own set of issues. I tried following your steps but one thing I noticed you said you were running UCKJ1 but isn't that 2.3.5? When I flash the exact same files I am still stuck without working wifi
Still noobing it up here - hopefully I can either stumble upon a fix like you did or spot someone else's that matches my issues...

Avoid that androidadvices.com **** - Half the time they link to firmware that isn't even for the device it claims it is, carrying a high risk of a hardbrick.

I only experienced this when I was trying to upgrade kernels using the SHOstock ROM. I get no wifi with siyah and can't send MMS with Entropy's kernel. That's the only time I've had those issues. Maybe you had a bad download? Glad you got it fixed though.
Just to clarify, those kernels work great with most other ROMS I've tried them on.

Had the same problem
I had this problem (with wifi, not mms) after rooting from 2.3.6. I eventually flashed Zedomax's kernel using mobile odin and wifi functionality was restored.
I still haven't moved on from there, but probably will sometime this week.

Weird, I cannot think of anything that would cause MMS to fail - what sort of errors?

It's happened to me several times after I flash a kernel. when I attempt to send an mms it just hangs and says sending but it never goes out. Could it be a conflict as I have Chomp set as my primary messaging app? Although if that were the case it should be able to send from one or the other but it doesn't. Can't remember for sure but I believe that I may have flashed the kernel cleaning script beforehand in each instance. The only way I've been able to fix it is to reinstall everything starting with the ROM. I'm sure it's user error.
As info, steps I took to try to fix before I restored:
1) reflash kernel
2) flash radio again
3) tried all 5 radios released (not a radio problem I'm guessing)
4) wipe dalvik and reflash kernel
5) run kernel cleaning script and reflash kernel
No dice, it was bizarre. Is this even the sort of event that you could get an error log from? There was no FC or any error message, you know? If it happens again what can I provide you that would help...can I do a logcat or whatever? ;-)
By the way,I could receive mms, just not send.

Could someone post step by step instructions on how to unroot so that I can restore my wifi?
For example, if in fact doing the factory data reset as described in the post above me is the correct course of action... is there a way to do a backup before so that I do not lose all my apps and stuff?

[HELP] Wifi/Bluetooth not working

Details of my problem are here: http://code.google.com/p/atrix-dev-team/issues/detail?id=115&can=1&start=100
Samcripp asked me to open an issue, but it was later closed as its not related to CM7.
Basically after updating to 0.19 Faux kernel and OCing, my bluetooth does not work (does not turn on) and my wifi says "error" and reboots if I try to turn it on. Logcats are attached in the link above.
Before this, I also tried the 1.35 Radio but I'm pretty sure it worked after flashing back to 1.77.30P.
I've tried everything from erasing via fastboot and clean installing stock 2.3.4, alien and CM7 -still nada. Tried restoring pds partition, nada. Tried different radios, nada. Only thing I didn't try was to SBF to stock. Can someone point me in the right direction to a SAFE SBF that I can used on an unlocked ATT Atrix?
Here is the dmesg: http://db.tt/92GSbZ4
Says something about buffer overflow, vdd.
Any help?

I got it to work momentarily but then phone froze and went back to error. I had followed these instructions: http://forum.xda-developers.com/showthread.php?t=1077329 and then did a dalvik cache wipe.
What could this be? Hardware?
Think its definitley a hardware issue. I can get the bluetooth/wifi to work by taking out the battery and tapping on the back of the phone..but then it dies later.
Next question: Any way to get "Unlocked" from showing on the bootscreen?
Had a similar issue
I once had a similar issue with my wifi after installing the same kernel. Consider restoring the stock kernel before you consider your phone broken. When you change kernels, since the kernel is central often, hardware is messed upOA component,
Have tried stock kernel, 1.83 kernel, faux kernel and kholk's kernel..all the same. Wiped cache/dalvik cache after all.
Getting replacement device from ATT. Just trying to figure out if I should send back with "Unlocked" text or not.
Theres got to be a solution, somewhere ... I can't get it replaced.
Someone...
was there a solution to this i am having the exact same problem
ive been running jokersax cm9 shortly after flashing 0.33 i noticed i no longer was hooked up to wifi. After looking into it i noticed bluetooth is also a no go.
it never gets past "turning wifi on" i have since done a complete format/factory reset, flash .33 and .4, went back to Cm7 still no change i have also flashed multiple kernels.
Last try was flashing radio N_01.77.37p still no luck
Having the same problem. Wonder if we can buy just the system board of this phone
Sent from ATRIX (CM7) using the XDA Premium App
Yes, Wifi/Bluetooth is a hardware issue! My phone just died of this same fate. If you want to take advantage of your warranty, then flash the 2.3.6 SBF after wiping all user data. BE CAUTIOUS. And can we make a big sticky for this problem? There are literally dozens of threads about this

[Q] wifi fail with any rom except stock

I've done some searching but haven't been able to find a solution to this issue.
Basically, the wifi on my phone just 'dies' after a minute or so with any rom or kernel that I flash other than stock. It even dies after flashing CWM or DD/Siyah kernel onto stock rom.
Any ideas on why??? My Captivate was like a tank and stood up to all sorts of flashing abuse and bad flashes. It seems this sgs2 is similar...with the exception of the wifi. On all roms but stock it seems that if I disable the wifi, then re-enable it then it will work for a minute...then die again. very frustrating.
please give me some clues
Thanks,
What router do you have? And what rom's have you tried?
Have you tried using other modems for our phone? Just wondering if maybe your router only likes the stock modem and when you're flashing other roms, it might be changing you to a modem your router disagrees with. It's just a suggestion, trying to think outside the box. There are two sets of modem builds, just make sure you get the right ones for the right roms. Also try flashing the stock KH7 modem back over the custom rom. I'm no developer so WTF do i know. Just trying to help a brother out. Good luck.
I've tried with both an Asus RTN12 as well as an older Airlink 101. Both B/G/N routers which I've tried the stock firmware as well as dd-wrt. They are setup using channel 1, WPAPSK/AES. Behavior is the same whether the router is set to 20Mhz or 40Mhz. Both routers are based off an RaLink chipset. I don't have a router based on Broadcom (yet).
As for Roms....
UnNamed
ICScrewD
ICS'd out
Coz
Serendipity
By modem I assume that's listed as 'baseband' in the about section of the settings. Stock shows KH7. I've flashed the stock kk6 rom and just checked and it remains kh7 (flashed with Odin).
I did an OTA update to kk6 but neglected to check the modem that was installed with it.
Regardless, the wifi worked as designed under both older and newer stock roms.
I'll flash a rom this weekend and then flash modems to see if I can narrow it down. I'm in the process of moving so the next day or two are sort of out of the question
I personally like WPA2 better (especially with dd-wrt), but to each their own. What do you have your wifi-sleep policy set to? (settings>Wireless->Wifi settings>Press menu button->advanced.)

If your phone is a Samsung i777 AT&T model and you want to get
your wifi working properly then simply download UnNamed v2.2.1
custom rom which is the very best custom rom currently available
for our phones. The UnNamed rom also has superior battery life.
The UnNamed v2.2.1 Custom Rom is not only the most stable and reliable
custom rom but it's also the most aesthetically pleasing rom which is currently
available for our phones. (i777 AT&T)
Since you have tried so many things already be sure that before flashing
another rom that you go into settings>privacy and select "factory data reset".
Then be 100% sure that you have done a "wipe data/factory" reset using
CWM Recovery before flashing another custom rom.
After you flash the UnNamed rom you will no longer have any wifi problems at all.
Be sure that after flashing the rom you make a nandroid backup of the rom
before you install any apps and or before for who knows what god forsaken reason
you should want to change or flash a different kernel rather than leaving it alone
and use the excellent kernel which the rom comes with.
Good Luck!
You sound like an advertisement for UnNamed
Seriously though...I have tried UnNamed from 2.1.1 to 2.2.1
ICScrewD from 1.4 to 1.6.1, etc.
Wifi completely breaks if I flash the CWM or any kernel over the stock. I've flashed so many roms, kernels, and modems over the past 2 weeks I couldn't even begin to count how many.
Just out of curiosity, have you tried connecting to wifi on a different router, like at work or a friends house...? Have you tried resetting your routers? With all that you've tried, it's just strange that you still can't get a connection.

I intentionally left the baseband separate from my UCKK6+root package because people often want to run a different modem than system.
Flashing a new baseband will do nothing for wifi - everyone who tells you that is too accustomed to HTC phones where Qualcomm AMSS runs EVERYTHING.
It's strange if anything but stock fails for you... UCKK6 wouldn't surprise me because it has all sorts of weird BCM4330 (wifi/bluetooth) problems, but I haven't heard of wifi regressions with my kernel when flashed on UCKH7.

Yeah... It's a little annoying. Yeah, Unnamed is an excellent firmware, but "best" is a matter of taste. It's funny that he's pimping a firmware when the firmware dev almost blocked him for that damn penis-gecko.

Logging into a router at work wont do any good since i work from home. the neareat open wifi network is out of range. I did log in to chic fil a once but unfortunately i dont remember the reaults....my mind was focused on lunch.
I have also reset both routers i have here. tried different firmwares foe the routers as well but got the same result...but both of my routers are based on ralink chipsets. two different ralink chipsets at that, but still made by ralink.

I forgot to mention, before you flash the UnNamed v2.2.1 custom rom
be SURE to flash the ODIN based CWM Recovery kernel, not the
CWM flashable kernel to start with.
(because who knows whiich kernel you have now since you have flashed so many)
Below is the ODIN flash CWM Recovery kernel which you should have
flashed in the first place when coming from the stock to custom rom.

Try resetting the security type in the wireless modem/ router to a personal wireless security and try it out. I had some issues with Wifi but after the resetting of the router, the wifi has been working fine.
In the advanced wifi settings, enable up to channel 14, and set your router to channel 11+40mhz (150mbps) and see if that works. Channel 1 might have too much interference for this phone or something... not sure.
Correct me if I'm wrong but aren't channels beyond 11 for out of US region?
Sent from my SAMSUNG-SGH-I777
From Wikipedia "In the USA, 802.11 operation in the channels 12 and 13 is actually allowed under low powered conditions. "
And its not like the FCC drives around looking for routers broadcasting in those channels, our routers are too weak to broadcast that far. But you're just enabling up to channel 14, doesn't mean that you're going to use it.
WiFi Fail MAC address Bluetooth address Unavailable
I am basically at the same point..WiFi Fail..It will scan and then turn back off. Started off with a stock phone..Followed the customizations steps..No problems reading the Flash Counter..Ran step 2c..It worked Great..passed..had UCKH7 but had no WiFi..Did the wipe data/factory reset as mentioned in other threads and WiFi returned..Then I did the OTA update to UCKK6 and WiFi was still working. So I downloaded Mobile Odin Pro from the market so I could complete step 3a. I had already extracted the zImage from Entropy's 1208 DD and placed it on my sd card. Ran MO on the phone selected the zImage and it ran flawlessly. I am still rooted and have CWM 5.0.2.7..but the WiFi shuts off again shortly after turning it on..So I tried the wipe data/factory reset again but it did not help this time. As far as I can tell everything else works great on the phone, calls, texts and so on...But after looking at some of the about phone settings..I noticed that both the MAC address and Bluetooth Address lines show unavailable...and I think that is why the WiFi shuts back down shortly after turning it on..Now I was going to move onto step 4 and flash UnNamed ROM for practice and then go back to stock using the guide..but I was wondering if I missed something important that caused the WiFi issue
What are the first 6 characters of your mac address? (on stock) At this point... I'm thinking they might have changed the wifi chip or something...

Currently under... Settings..About Phone..Status..Wi-Fi MAC address & Bluetooth address show "Unavailable"
But since I have an access list enabled on my router...I would say my MAC address started with 04:46:65 I'll be able to verify that when I get it back.
I'm going to try another wipe and a different Entrophy Kernel and see what happens. I know I can get WiFi back by going through the steps again and I enjoy all the tinkering..so I just wanted share some of the stuff I was seeing.

...If you bootloop or things behave wacky, enter 3e recovery (stock kernel means stock recovery) and do a Wipe Data/Factory Reset. If you are reverting from UCKK6 back to UCKH7 you MUST perform this step or wifi will not work.
I Did not go from UCKK6 to UCKH7... i don't think?? So any help on what i need to do would be awesome!
AT&T is the carrier.
Also without having to 100% wipe and re-install.
You need to find the "Return to stock" thread and go from there.
Zedo's kernel is ancient, it will not provide wifi with UCKK6 system images.
Only my kernel, the UCKK6 stock kernel, and (maybe, not sure) SiyahKernel will provide wifi with UCKK6.
Kernels are <8 MB. 300MB = full kernel and system image restore.
My guess is you flashed a UCKH7 stock kernel.
Found a return to stock thread and it mentions a RUU_Ace_Cingular_US_1.80.502.3_Radio_12.39.60.19_2 6.06.04.06_M_release_166557_signed.exe as well as a pd98img.zip which are also both 290MB...

There are a LOT of thread on this and i have been reading thru as many as i can...

Wifi Not working
Sorry guys, iam needidng your help.
My Galaxy S2 SGH-I777 suddenly the wifi stop working as well.
When i push button to put on. The Wifi show me this messege “Stating on…”
But never finish to starting.
and if I let a few minute alone, it put off automatically.

Sounds like it could be hardware failure. To test that, flash back to straight stock followed by a wipe data/factory reset from 3e recovery. If the problem persists, then it is either a problem with your phone hardware, or a problem with the available wifi router signal. You can test the latter by trying to connect on different routers.

Thanks for your response.
I dont want to belive that my hardware is broken.
But i flashed again my SGH-I777, and the problem persists.
My wifi just says "Turning on" when I push button, and it never boosts again.
I changed the kernel and the rom. I restored to old factory settings, and nothing works.
I would like to get back my wifi.
i appreciate your opinions about this issue.
WIFI suddenly stopped
My WIFI also suddenly stopped working
on 7-1-13 I installed aokp_i777_ota-eng-task650_6.24.2013 worked for a month
Yesterday the WIFI stopped connecting. Got a constant "Turning on Wi-Fi" message but nothing else
I installed aokp_JB_i777-ota-eng.task650-ktoonsez-11.20.2012 which I had been running for the last 6 months
Same problem
I did a full wipe. Wiped cache, data, dalvik. Did a fresh install, then wiped cache, dalvik and fix permissions.
Same
a i9100 thread linked a video of a leaking battery inside that disabled wifi
took phone apart, no obvious signs of hardware failure (have pics)
used odin3 v1.85 with ATTGalaxyS2Unroot_SGH-i777.tar to unroot
wifi will turn on scan for a minute then turn off -- will not find any AP
router working fine with my other i777
anything i missed?
My wifi is working fine

hey brother, first of all, your wifi is not damage fisically. But you are in the same situation that i was.
my SGH-I777 is working very well after too much work with it.
i gave my cellphone to my little brother, and two days later he told that the wifi was working fine.
i made this face O_O i couldnt believe what he was saying.
right now i dont know, how he resolved the problem, the only things that he did was change the OS i guess.
i will call him tomorrow to ask about the solutions, but man, dont worry too much coz you just like my brother, will resolve the problem
It is not hardware...
found another thread that suggests FXR WiFi fixer app from play store.
Ran it on the the AOKP JB 4.1.2 from 11.20.20102
seemed to solve issue -- connected to wifi but lost connection after ~30 min
same issue -- constant "Turning WiFi on" message.
ran FXR again -- connects temporarily then loses connectivity
same thing every time i run FXR
should i use a different ROM?
which one?
any help is GREATLY appreciated
Thanks
mike

You could ask in the AOKP thread if there are others experiencing wifi issues with that rom. If not, a fresh install of the rom may solve the issue. It definitely sounds like a firmware issue, but when there is any question whether the issue is firmware or hardware, the test is to flash back to stock and see how it works. As far as which firmware to use, there are a number of different firmware that are completely stable. You should read through the developer threads, and then try them out to see how you like them.

[Q] Calling problems on my SGS2

Hi Guys,
I've run into a bit of a problem and cannot find my way around it, my phone can be used for everything except making a damn phone call i.e. I can make calls, folks can see me calling and receive it but I hear a blank on my end and so does the receiver, no dialogue. I tried everything listed on other topics but cant seem to get phone calls working again....so please help....
I know exactly when this started happening so here's the details
I was running the Foxhound 3.0 ROM listed in the following thread and it was running perfect
http://forum.xda-developers.com/showthread.php?t=1486199
then I found a new ICS theme posted on the following thread
http://forum.xda-developers.com/showthread.php?t=1334922
and tried flashing that according to every step mentioned and although the ROM was running ok, I couldnt access system settings because my only option available was NOVA settings, my back button, phone calls & wifi wasnt working.
I looked into some of threads posted on the forum listed below and tried out every step to fix the problem but to no avail.

List of methods attempted
1. Restore mirror from my stock rooted ROM - fixed wifi but no phone calls
2. Restore mirror from ICSrewd ROM - same result
3. Used ODIN to go back to Unrooted Stock - still no phone calls
Kernel + non-rooted UCKH7 system package
4. Used ODIN to flash a different Kernel with root - same result
Kernel + cache + rooted UCKK6 system package
5. Full wipe and reflashed ICSrewd - same result.
Now i have so much info cluttered in head that I'm experiencing what people call 'writer's block' or what I would call 'Brain Dissolution' :-(
Can anyone please suggest a solution for this? My current phone deets are as follows
- At&t Samsung Galaxy SGH i777

- Siyah v2.6.7
- Build ICSrewd v2.0.1 KL1

You got an i9100 modem on your device from something you flashed (probably the theme package from the i9100 forums - but I didn't d/l it to look) as evidenced by your baseband reporting i9100XXLPH.
Though I think some of the packages you have tried flashing to fix it have modems, I would go to the appropriate modems thread (I think they are linked from the sticky in general) and grab whichever i777 modem you were running before and flash that...

Ok, so here's my question, when I flash the Stock ROM, doesnt it already come with the stock modem too? or do I still have to dl and flash the stock modem separately?

ICScrewD should have given you the UCKH7 modem. Not sure why it didn't overwrite your i9100 modem. As I haven't been in this situation to have to get out of it, there may be more to it. My first step would be trying to flash just the correct modem package over what you currently have...other than that, others have been in this situation - search is your friend.

Ok I was still on ICSrewd when I tried flashing UCKH7 but it didnt overwrite the i9100 modem even after multiple flashes. I tried doing it thru ODIN and it still failed. So I went back to the Stock ROM and re-tried it and guess what....success!! ......which is weird, I'm not sure if it is an issue with ICSrewd new version 2.0.1...anyhow...now I'm experiencing ridiculous battery drain, so should I try various modem combinations to see which one works?

After all that flashing, you'll probably see heavy battery drain for a few days. I usually have to go 3 battery cycles full to empty (which is 3 days for me) before I see stable battery behavior after flashing new roms.

I should've read this earlier
What I did instead was flash the turkbey ROM and went thru 2 cycles with it already so now I'm seeing some level of stability i.e. 19 hrs of battery time approx with about 5 hrs of Screen On time, which is pretty decent I guess.
Thanks for advice mate.

[Q] Samsung Galaxy S2 stuck on 'turning WI-FI on'

Hi Team,
I have a GT-19100T which had the carriers firmware (Vodafail AU) 4.1.3 (rooted) running with no problems until recently (2 wks ago), prior to the fault I have had this phone for years no glitches great phone for its age.
I had let the battery drain, upon re-energizing the phone and attempting to turn on the wireless i noticed it just reported "Turning WI-FI on" and the toggle switch was greyed out. this would last all day. switching the phone off and on would not stop the process of the phone attempting to turn wi-fi on.
I immediately went searching forums and people suggested hardware fault or perform factory wipe through CWM.
Troubleshooting I have performed so far is:
- factory wipe and cache cleanup (not resolved)
- flashed to CM 10.1.3 (not resolved) (multiple times)
++++
OS: 4.2.2
Baseband: 1900TDULP4
kernal version: 3.0.64-cm-g9c2e2bc
++++
I have found from research that the Bluetooth and wi-fi are the same module (I maybe wrong) and Bluetooth is working fine.
So this leads me to suspect a software/firmware fault.
I'm currently downloading I9100TDVLSM_I9100TVAULSF_VAU.zip from (sam mobile) the latest release for this phone from the carrier to see if firmware will resolve the problem.
In the mean time any suggestion, advice, help or solutions would be greatly appreciated.
Maybe if someone knows of a file i can flash specifically for wi-fi module that I could try.
Thanks in advance

I have same problem few weeks ago when my galaxy on Stock Rom 4.1.2.
Later, I try to reflash again through Odin, then install CWM and I flash CM 10.2 4.3 through CWM and it solved.
I think you should try to flash Newer Rom version, example CM10.2 or SlimKat.
Good luck

Thanks mate for your reply,
I installed cm 11, this did not resolve it.
need the file for the radio/modem, i'm hoping this will fix it but not sure exactly what I am looking for.
**Update***
Just finished installing I9100TDVLSM_I9100TVAULSF_VAU (latest release from Sam Mobile) 4.1.2
Still wi-fi not working.
will try and install cm 10.2 on your recommendation huytrandinh
Okay latest nightly of CM is installed cm-10.2-20131216-NIGHTLY-i9100.
Still has not resolved the wi-fi issue.
anyone have a potential solution?

Try to flash a modem using odin,
Sent from my GT-I9100 using xda app-developers app
Modem won't solve the issue as WiFi/BT drivers are in the kernel on the S2. OP was on the right track, but for whatever reason a clean install of stock didn't fix the problem.
Maybe try the 3 part firmware in Hopper8's Odin Troubleshooting thread, then a clean install of the Voda stock rom after that ?
There's 'WiFi fixes' (which are actually the LTE modem) for the I9505 as it actually has two separate modems, and the LTE modem also controls WiFi (which isn't the case with the S2 as per my comment above).

Thanks Mistahbungle,
I checked out that thread http://forum.xda-developers.com/showthread.php?t=2345831
Nothing i could really use.
But I did try a few other kernels:
Siyah-s2-v5.0.1
Unfortunately as soon as flashing with other kernels the screen would go black after the initial boot logo.
Only way to resolve it not booting into the OS was to roll back to:
1. GT-I9100_JB_ClockworkMod-Recovery_6.0.2.9 (flashed with odin)
2. flash CWM-SuperSU-v0.97 with CWMRecovery
3. install cm-10.2-20131216-NIGHTLY-i9100
4. then your general cleaup through cwmrecovery
I'm not sure if I'm doing something wrong when trying to apply another kernel.
anyone able to offer assistance please with right kernel?
cheers

Just found a post in that thread - http://forum.xda-developers.com/showthread.php?t=2345831&page=6
Will try the 3 part rom XXLSJ for GT-I9100.
Fingers crossed
Yeah, that's what I suggested in my PP. Sorry, seems the 3 part was on HotFile & Hopper didn't have his own copy up somewhere.
The rationale was - there's possibly something from a previous installation causing your issues, and flashing the 3 part would wipe your phone. I realise you've done this manually, but at this stage you're fast running out of ideas before you declare it a possible hardware issue, and it was worth a shot.
So...What I'd try is - while you have a rooted phone, go into CWRecovery and format everything/ (not EFS though obviously, or your external card if you have one), then try re-flashing whatever stock firmware you have with Odin in download mode.
Edit - Also, maybe do a Google search for that 3 part firmware (details are still on Samfirmware, just that the files are gone), you never know, you might find it somewhere.

Okay just finished testing the rom by installing it via odin (3 part)
still has not yielded any favorable results .
Little disapointed as this was a great backup phone and served for the past 12 months as a mp3 player
Guess as they say; It is all planned obsolescent which is fracked ...
Thanks for the suggestion/help anyway.
I know this is an old thread but my gs2 had this problem and I was able to fix it. Using es file explorer made my way to /data/misc/wifi pulled up the properties to wpa_supplicant.conf and changed group to wifi...then wifi finished initializing...hope this helps somebody
Sent from my SM-T310 using XDA Premium 4 mobile app
for consideration.
I have this phone. the GT-i9100. Had this issue also. I took it apart. The little onboard battery had blown and corrosion got all over all it.
and guess where WiFi hard is. Right Next door. I cleaned it up real good. Put it back together and WiFi came back to life.
So give it some thought guys.
