WiFi and Bluetooth not working - Networking

My phone is a Cubot One running MIUI 4.8.29 custom ROM v6. One day, my WiFi spontaneously ceased to work. I thought it was a temporary glitch, so I rebooted. It worked again. Then, it spontaneously ceased to work AGAIN. since then, it had just been off and when I try to turn it on, it just greys out for a few seconds and switches off again. The same thing happens to my Bluetooth. However, twice, randomly, about 4 months ago and 6 months ago, it notifies me of possible WiFi networks. It stays like this for a couple of hours, then returns to the aforementioned state. I have tried a full reset several times with the stock ROM and others to no avail. I've been using mobile data since then. I don't know how this has happened and I am wondering if the altered build properties of the custom ROM have anything to do with it. The WiFi-pertinent ones are attached. Please help - not having Bluetooth or WiFi prevents me from selling the phone. Thanks all!

Two problems: wifi won't automatically connect and "android is upgrading"

I've got a rooted S5. A few weeks ago, I tried to flash cyanogenmod, and screwed things up pretty royally. I eventually flashed to a roughly stock rom, so I'm running 4.4.4. For ease, here are two screenshots.

Anyway, I managed to salvage my phone and everything is basically working, except for two things:
1. My phone no longer automatically connects to the wifi at my house or at my in laws. It does at work, for some reason. My wifi password is ten random numbers and I've got them memorized. I've got unlimited data with sprint, but not unlimited patience.
2. Whenever I restart, I get the damn Android is upgrading thing, and it's always two apps that need optimization. Again, it doesn't really matter, but it's one of those little annoyances that are driving me nuts.
I've got philz. I'm running xposed framework.
Help?

Wi-Fi stopped working on rooted Galaxy S7

I own a Verizon Samsung Galaxy S7 (G930V), rooted according to psouza4's root guide and fine-tuning guide , with Coolify. Everything was working great, until two nights ago. That night, Wi-Fi randomly stopped working on the device. Upon inspection, I found it had not only disconnected from my network, but had also turned off its Wi-Fi signal.
I tried turning it back on, both through the notification tray and the android settings app, which says it is turning Wi-Fi on for a few minutes, looking like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
before giving up and returning to this:
I've already tried reboot, wiping the cache partition, toggling airplane mode, cellular data and bluetooth, all to no avail. I am unsure what is causing this problem and whether it is hardware or software related. I only have a finite amount of cellular data and much prefer to be using Wi-Fi. I am hesitant to resort to a stock reset of my phone, losing all my apps, data, and hours of customization, though I will if I think I have to. Any advice will be much appreciated!

Wifi not working suggestions needed

Hello guys, I was using Google edition ROM for 1-2 months in my LGG2 D802
A week ago suddenly the wifi stopped working. It keeps showing turning on wifi and nothing happens.
I flashed other ROMs at the settings wizard the wifi started but turned itself off after few minutes.
So I visited LG care nearby, they flashed ROM in it to check if it starts working and it didn't.
They suggested to replace the board which will cost 5k INR
Should I go for it?
*bump*
FINALLY WiFi TURNED ON!
FINALLY!

What I did?
- Flashed stock ROM
- kept wifi turned off
- turned off automatic date update
- then turned on wifi
So, basically its the automatic date update which is killing the wifi everytime. don't know why..
Please inform to people to try this method facing this issue.
Thank god didn't sell it for 5000Rs :laugh:

Dead ram

Hello, I have a problem with my android car unit that it's driving me crazy. I bought this unit 6 months ago (aliexpress . com/item/Two-Din-Android-7-1-1-7-Inch-Car-DVD-Player-For-Mercedes-Benz-W209-W203/32554899913.html(I'm not able to put links)) and it work well until a some weeks ago. It started to slow down and to restart randomly. I decided to investigate to see what could be happening and I saw that now I only have 1GB of ram instead of two. I don't know if any of you had this problem before or has any idea how to solve it.
I would like to try anything before sending it back to China
Regards
UPDATE
So, today going back from work I noticed that the radio started up faster than I used to this last week, and when I went to settings -> ram I see that I got my 2GB back! Sadly after a while the radio crashed, all the buttons stopped working, the screen was white but the music that continue as if nothing happened. After I force the reboot I see that I still have my 2GB. I think defenitivly it's a problem related to the RAM or MCU.
I taked a couple of pictures of the version that I have, here they are:

Android Auto issues

I've had nothing but issues with Android auto on my 2019 VW Tiguan and now it just flat out refuses to work.
Only had the car for about a month and AA worked with spotty results for that entire time. It would randomly disconnect on the head unit and I'd have to reconnect it. The other day I decided to do some troubleshooting, reinstalled and now it doesn't work at all.
Tried new cables, different USB ports and even tried my wife's S10. Both now give me the same result. I tried it again today, it turns AA on my phone but when I click the apps screen on the radio it tries to pass it to the radio, gives me a data permission popup on my screen but then gives me a read error on the radio. It keeps looping and trying to reconnect. I actually tried doing it on some rental cars I was driving a few weeks ago, wouldn't work either on those at all. I've attached the screenshot of the popup that comes up and also what my radio displays. It also displays that for my wife and her phone is bone stock and no customizations.
Any tricks to get this dumb thing to work?
