Ok guys. I browsed through the forums for this but can only find my issue on custom Roms. My issue is with my wife's phone on the Stock Rom. I rooted her phone the other night and since then her phone has no wifi signal til a reboot then her wifi comes back in nice and strong.
Is this a known root issue? Her phone is on 4.0.1, which I believe is the latest firmware for this phone to date. The only thing I did after rooting was, of course, install apps necessary for root and flashed a security program. Nothing else.
Background:
I was previously rooted and even after disabling root I could not do the OTA (it kept giving me a status error 7). After researching I decided to use ODIN to try and restore to a stock ROM for the upgrade.
I initially tried to use CI605_I605VRLJB_I605VRALJB_CL414933_HWID04_HW_Rev0406_low_ship_user as the firmware, but it caused my device to go into a firmware upgrade error.
I then used I605VRUEMJ9_I605VZWEMJ9_I605VRUEMJ9_HOME which got me back to stock 4.2, I OTA'd to 4.3, and using a previously downloaded OTA copy of 4.4.2 I booted into recovery mode and manually installed the OTA.
The Problem:
Since going to 4.4.2 (and I noticed it in 4.3) the Google Play store seems to load EXTREMELY slowly. I have Frontier FiOS and speed testing the connection shows a minimum of 25/11.36 Mbps for my connection. 4G does not appear to work so well either.
Could I have messed something up? I do not know why my stuff is working so slowly...
Device: Galaxy S3
ROM: Slimkat
ROM version: Slim-4.4.4.build.6-OFFICIAL-5242
Build: slim_d2lte-userdebug 4.4.4 KTU84P 5242 test-keys
Kernel: 3.4.95-cyanogenmod-gd56ed95
I purchased my S3 in April of last year (4.1 Jellybean), and at the time the wifi worked perfectly. After the first (or second?) OTA that was pushed to my device, my wifi started acting up. It would cut out and I would have to cycle the wifi off and back on in hopes it would work again. I have been patient hoping they would push an OTA that would finally fix it. A year or so and a few OTA (I don't recall how many, or which versions) later and it still doesn't work properly, so I decided to finally try a custom rom to see if it would solve the issue. The last stock version of android I was using was the 4.4.2 OTA.
I rooted my device using towelroot, flashed CWM Recovery (CWM_6.0.4.7_Non-Touch_GT-I9300) using ODIN 3.04, then proceeded to flash the Slimkat rom listed above using CWM recovery. The wifi seems to be better, but it still cuts out and is unresponsive even though it says I have full wifi signal. A wifi cycle seems to fix it temporarily, but I'd like to solve this issue.
So as far as I can tell the last working modem I had was stock 4.1 or so. So I guess my question is, can I flash previous modems to try to get a working one with this rom? I have tried using WIFI Fixer from play store, and even with full signal on WIFI I get signal poor, signal hop scan messages spammed. Any and all help would be greatly appreciated!
I'll try keep this short; I flashed Marshmallow and had awful WiFi, so i downgraded to 5.0 and the wifi issue stayed. After flashing different 5.0 firmwares and messing about i managed to fix it.
I noticed my carrier re-released MM, so i assumed the WiFi bug was fixed, and of course; I was wrong.
Present time: I flashed back to 5.0 again and now the WiFi issues have stayed, Ive been spending the whole of today messing about with different firmwares trying to find one with WiFi that doesnt suck. Wifi appeared to get better one time however there were performance issues (for some reason)
Any idea how I can return to stock 5.0 with Wifi working? I've tried just flashing Modem and I've probably flashed about 6 times since i was last on MM.
EDIT: IF YOU KNOW HOW TO FIX MM WIFI THAT WOULD BE EVEN BETTER
I have not had any network related issues on my Redmi Note 3 (SD) from day one, that was until I flashed Official CM13 a few days back and people have started complaining about not being able to hear me properly. Even the signal strength was weak and often fluctuated. I moved back to the latest Global Beta (flashed fastboot rom using MiFlash) because of this but the same problem persists.
Looking for some help.
