[Q] Wifi not showing anything - Galaxy S II Q&A, Help & Troubleshooting

Hello .
I have and had this problem since cm11 for a long-long time . The wifi just doesn't show any AP when it should . Now I had this problem on cm 11 and the workaround was to switch wifi reign code to china ( or anything ) and instantly AP's would appear again .
Now I am using cm12 by Lysergic Acid and the problem is as far as I know there is no reign change in android lollipop . I was on beta 13 without problem . When beta 14 came I clean flashed it and there was no wifi even in first setup screen . Went back to my backup of beta 13 and wifi worked without problem . I have downloaded the build 04/23 and it is the same problem .
It is not hardware related because my old backups work perfectly . New flash of android 4.1 and cm11 also have no problem except maybe cm11 need wifi reign change once in a while . My info is as follows :
baseband version : i9100XXLPQ
If kernel is installed with a clean flash of cm12 by Lysergic Acid then I have not changed it .
I have been on cwm v6.0.5.1 for as long as I was on cm12 . Not sure what variant of unofficial build it is .
If it is a recovery problem can you point me to one compatible with cm12
I believe baseband is for 3G modem . If it has something to do with wifi plz correct me . I have no problem with my 3G.
I also don't see any 5GHZ wifi . I always assumed i9100 doesn't support it . But I think I am wrong .
Any help would be appreciated .

Sorry if this reply seems stupid, but did you try to turn off wifi, wait 5-10 secs and turn it on again?
I've had similar issues and waiting few seconds before turn it on again made the trick...
Hope it helps

Yes I have tried that . It doesn't work . As I said it happens even during startup wizard . No playing with the key solves the problem .
I have installed Ressurection Remix latest lollipop and It shows wifi correctly . Now that I think of it I installed some roms other than CM and I never had this problem . But I had this problem since cm11 in Cyanogenmod variants ... I'm gonna see if I like RR enough to keep .

[Q] SK17i WIFI STILL NOT WORKING

Hello, I have a rooted xperia mini pro SK17i and I'm stuck to the CyanogenMod ROM 7.2.0 which seems to be the only one to work with my device.
I have written to you in the past to ask: "Why the wifi stops working if I try to install the cm-9.0.0, or 9.1.0-cm, or 10 cm-.........? ?? "
but no one has ever found a solution or the solution just did not work ...
I know from what I see in the forums that mine is a very common problem.
Now, years later, I ask again the same thing: "What should I do to install a more recent rom without losing the wifi?"

wifi is defend by your kernel install.. try use another kernel like cm10 or cm11 and make full wipe n install your rom again.. or switch to another kernel and rom..
When I installed the cm-9.0.0 I used its kernel and I did the same with the 9.1 and the 10 ... did not work ..
But maybe I did not understand. You say, for example, if I install the 9.1 should I try Kernell of 10? Does it make sense?
Please........ :crying:
Does WiFi work on Stock ICS 0.587 firmware ?
I am ashamed but I do not know what it is ...
I'm no expert, I have not yet figured out a lot of things ... I'm still learning ...
I followed a guide to root my device and install the cyanogen rom.
If I look in the device info read:
Kernel: 2.6.32.9-FXP root @ ubuntu # 6
Android version: 2.3.7
This is all I know ...
Before roottare the phone I upgraded the original operating system of the phone and the wifi stopped working.
Precisely for this reason I decided to install the CyanogenMod ROM: to try to recover the wifi.
The cm 7.2.0 did it. The newer versions like 9, 9.1 did not work ....
My question is .... why??? it is obvious that it is not a hardware problem ...Because if it were so it would not work even with cm 7.2.0 ...
I'd like to update my device to the latest stable CyanogenMod rom for my device which is 9.1 ..
But I can not because the wifi stops working ... Heeeeelp!!

i think you ALLWAYS forget to flah the needed kernel. (& allways have this old GB kernel) so only wifi works with this.
you should make sure you following the install EXACTLY.
also cm 9.1 is old like hell. this is also no stable release. at least i wouldnt call it like that.
Look for LX (Legacy xperia) which provides cm10.1 , 10.1 (jb) & 11 (kitkat) this is far more stable. also many bugs fixed there.
cm 9(.1) is abdonned long time
First of all .. Thank you so much for your help.
Ok .. I'll try .. I'm just worried because in thr LegacyXperia site I see a lot of bugs in the Working / not working lists..

ok good luck this time all works incl. wifi (should work 100% if doing all right)
i think the best is to test a rom 1st so you can say how it fits your usage . just a few tips:
-use minimal gapps after flashing rom
-LX 10.1 has a release candidatefrom march this year its a pretty stable daily driver. dont use the 10.2 release theres nothing better..
-maybe also you can test cm11 if want, but keep in mind 19/3 is the last PMEM build which is based on old kernel, will probably deliver the stablest experience. IMO the latest release is also very good but this contains some bug like the ANDROID_OS wakeclock (need power on phone on charger to avoid this) & its still in development (so its more for dev users)
for the buglist:
CM10.1:
- maps flickering its true but fixed in CM11
- wifi gets drops sometimes .. but it work at all
- camera is not good quality/buggy bcuz of driver lacks (also no 720p video)
CM11:
- sometimes wifi a lil bit buggy but its minimal. works like a charm for me
- 720p video is working here
BOTH:
-sometimes bluetooth battery drain after using it (need reboot to fix) i not face this is issue when i send something to friend.... (works normal..)
- NO FM radio, HDMI port will not work (if you have one) & ANT+ (no drivers)
good luck for you
Yesterday I installed the CM11 and ... it works!!!!
The wifi works! :good:and I like the rom.:good::good: ... so ... thanks a lot bejunk!!!! thanks thanks a lot!!!!! You are a great!!

np bro im happy you have now good rom & working wifi
just 1 thing if you use the latest version (02/07) it has a bug that you get android os battery drain. you can solve this by:
-power off phone
-plug in into charger & wait till you see the battery logo
-power on . done
Thanks again! The only problems with this rom are:
- the phone takes a long time to boot. Almost two minutes ... every time ..
- When the device starts up many icons disappear and others are in different positions ... I do not know why ...
Is there a way to fix these problems? Maybe I did something wrong during the installation ...

There's a Q&A section for that ROM. Anyway, long boot time should be fixed in the upcoming release. The simplest way to fix disappearing icons problem is to install another launcher. Hope I've helped.

[Need-Help] Building CM-11.0 for Karbonn Titanium S1 Plus [Phicomm C230WJA]

Hi,
I am learning to build android ROM and trying to build CM-11.0 for Karbonn Titanium S1 Plus (msm8610) a.k.a Phicomm C230WJA. In the last three months after lots of efforts I progressed up to getting working kernel and going past the boot animation.
Now, I am facing the following problems when running the ROM on actual device. Your help would be greatly appreciated.
Note: I am building it from source using CAF kernel, display and media.
1. After flashing, first boot gets past boot animation and only Top status bar appears. No launcher, no icons, no wallpaper nothing only Cyanogenmod's debugging icon, battery icon shows up, rest of the screen remains blank.
2. Second boot (reboot) does not get past boot animation.
3. When screen locks itself, it gets totally white. This also happens when phone is powered off and charger plugged in. I mean screen turn off issue.
4. Lock screen appears as it should be with background image and few icons etc.
Please let me know if you require anything related to above device.
Regards,
SDhi
SOLVED
Thanks.
I resolved all issues by myself.
1. Somehow CM-11.0 forced me to include (not inherit) vendor/cm/config/common_full_phone.mk file to build all CM apps.
2. White screen issue was related to Backlight. Made modification to kernel and problem has been resolved.

Sameer Dhiman

Yes, an alpha version of CM-11.0 but I am not satisfied with the voice coming out specifically from earpiece during call. I can not understand what the person at other end is saying. He/She can hear me loud and clear. It appears there is some bug in CM-11.0 framework with dual sim phone.
To till date I have tried the followings
1. CM-11.0 voice call quality issue with earpiece only. Other things works fine except GPS.
2. CAF-4.4.4 GPS module gives kernel panic and crashes. Stock Proprietary blobs are not compatible.
3. Omnirom-4.4 does not support dual sim. Fastest ROM among the others. Trying to port dual sim support in Omni-4.4 chances of success is 1% or 2%.
4. CM-12.1 incompatible stock RIL Proprietary blobs. Same IMEI assigns to both SIM slots and SIM does not get detected.
5. Omnirom-5.1 same as CM-12.1
6. CM-13.0 build does not even start gives /.txt, /5.txt or /6.txt error and stops. CM-13.0 major bug.
7. Omnirom-6.1 unknown reason gives Kernel Panic and crashes.
Currently, giving a try to CAF-4.4.2. Let's hope for the best. I have already invested lot of time (days, nights, weeks and months) but the outcome is only failures but I have not given up. There is still hope remaining inside me.
Regards,
SDhi

In-Call audio issue has been fixed but I would require some time to polish the ROM before beta release.

If the rom is still being updated, and newer versions will come, then it should be fixed in next updates, and you said it works in stock nogut, then it's definitely a rom issue.
PS: you should QUOTE my post or mention me in your post by adding @MigoMujahid in your post so that i can get some notification that you posted.
Ok.
Sorry but, the Miui's roms are based on Marshmallow, not Nougat...
Its the stock rom official from samsung installed after for waiting a solution for miui . Sorry for the not good explaination ^^"

No i understand you well
I meant if it's working in stock nogut, then it's a MIUI 8 rom issue.
Everything it's ok for me now !
Before, my installation of twrp and miui, was from marshmallow stock samsung. And, with this way, i have so many errors.
But, with twrp installed on the Nougat stock rom, i don't have any problem, calls working, google apps working too !

Wi-Fi drop issue on Marshmallow-based ROMs

As you know in the title of this thread, I, like many people using Marshmallow-based ROMs for G7102, am having some problem with the regularly dropping issue of Wi-Fi. Checking all the info and logs of the Wi-Fi, I notice some very strange behavior
1/ In DHCP mode: Scan constantly even when connected to a network, after few scanning, the phone started to disconnect and begin re-handshake with the network
2/ In Static mode: After changing to the Static mode with an appropriate profile (tested profile on another device), the phone connected to that Wi-Fi then said that there is no connection (even the profile is correct and tested), after that disconnect and re-connect constantly, turn into Wi-loop
All of this happened even when the phone is in onscreen, sleep happened to be a little bit more intense with the DHCP mode problem. Wi-Fi, even in an intense usage, will drop. That's really a nightmare for a normal user, let alone an MOBA gamer and streaming-enthusiast. This happened to me with all Marshmallow for G7102 ROM (XOSP, AOSP, CM) - now I'm using XOSP.
I hope that we could find a solution to this problem or, at least, discuss this problem together.
Btw, I found someone said that Rio Kernel should fix the problem, but I don't see the link to the kernel. Can anyone upload it here for me to test it?

I can't talk for sure that the problem lie on the kernel (cuz I also knew that Rio kernel just run for older Android version, but some of the post's replies talk about it like a cure for the problem)
But I have a theory that the problem related to the IP mechanism, cause based on the inconstant behavior of WiFi (Static and DHCP problem).
Have any idea?

I think the wifi settings in system\etc are not correct.
It happened to me.
Disconnect at every 5-10 min.
And i discover that on the LOS based rom i m not sure about AOSP because i m not using the notification are delayed.
Around 10 min after the message are send if the phone are in deep sleep around 10 min the notification delay a loot.
I found a fix but really dissapoint about custom rom development.
I don like the Miui stock rom but whit thats bugs .
So we need a pure stable aosp rom witch some config change and PA theme engine so i don need to download every week new build and start fixing the bugs after that.
I read in one plus forum the some users have the same problem but after flashing frimware the problem was solve.
So the next question is which frimware package we have to flash to fix the wifi dissconect.
I tried AndroidOne and wifi is stable. I would like to understand where to intervene to solve the problem with other lineage constructions 14.1 and 15. Maybe I have to change the Kernel? do I need to intervene in the Build.prop file?
