Wi-Fi drop issue on Marshmallow-based ROMs - Galaxy Grand 2 General

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?

Your ROM Name & Version ?

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?

Wifi tether on Sony based custom rom for Xperia 2011

Hello
I'm trying to use wifi tether on my SE Xperia Neo V with Suave kernel and Ultimate HD 3.0.2.
Once setup is done and hotspot activated, I can connect my laptop and tablet to the wifi but there's no internet connection.
I've tried various combination of kernel and custom ROM (all based on sony's ROM) but ended up with the same result.
However, it did work with Cyanogenmod back when I was using it.
So, I'm guessing it might be because of sony's ROM, could anyone confirm that ?
Is there a fix ?
Does anyone managed to make it work ? with what kernel and what ROM ?
Any help would be appreciated.
thx
Also, it works on Cyanogenmod Nightly 10...

strange.. with stock Rom could you tether?

Yes, as far as I remember. But I then changed for cyanogenmod, then to another provider that didn't support tethering.
I just noticed that now that I changed for another provider...
anyone ?!

Yes, you'll get your 10 posts...
OK, I've tested many ROMs and none of the Sony .587 based ROM worked (the roms are working but not the tethering). Not with wifi nor bluetooth.
I've tried many things and only cyanogenmod works on that departement.
It has to be system related because all the apps I've tried (barnacle and such) didn't work either and some even caused the phone to reboot.
Also barnacle says WIFI: could not set ad-hoc mode of wlan0: Device ore resource busy
anyone ?
OK, I've found a solution.
After many tests and research, it seems to be specific to SFR french carrier and android 4.X (no wonder it was working for nearly everybody but me...).
The thread with the answer is http://forum.xda-developers.com/showthread.php?t=1544063
Now, it needs to be done once the hotspot is activated and it will keep working as long as you don't reboot your device.
Would there be a way to "integrate" that in the ROM to make it automatique somehow ?
Anyone ?
Ok, anyone knows how to make the iptables parameters permanent in android ?

[Q] Wifi not showing anything

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 .

[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

Suthar,
It is still work in progress. I am working hard to make stable kernel. This is an essential foundation part.

Have you made it ?

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
Thanks a lot for that. I would like to try that one. Have you posted that on the forum ?

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

Phone shutting down at 40%

Hi,
As the title stated, I have Redmi Note 3 SD with LineageOS installed. My phone suddenly dies at 40% when I put it on standby. Sometimes when I open camera app, it dies at 50%. I've tried many ROM including ViperOS, RR, but I haven't tried with MIUI yet mainly because I don't really like MIUI.
Have any of you guys get same experience as mine? What you guys do about it?
I'm planning to replace the battery because I thought it was the battery problem. But if you guys have any suggestions that would be great!
Thanks!
Update the IOS problem will be solved with new 11.2.1 version.
Just kidding
I would replace the Battery to fix issues like this if you the only one related to a specific Rom.
If you search trough the los thread you will see that some people had the same issue. I am not sure how they fixed it but i think some of the custom kernels had a patch to deal with this issue. I cant remember which one ( agni or radon) so you should search trough and/or ask those kernel developers.
This problem solved by changing kernel to francokernel. Thanks!
