Soft reboot issue when activating hotspot or usb thethering - Xiaomi Poco F1 Questions & Answers

Salut XDA Members,
I am experiencing some weird issues with the latest stock OS 8.1.0OPM1.171019.011, on 128GB (EU) Pocophone F1 which causes the phone to ?soft? restart (I don't need to enter SIM-pin, but Bluetooth disconnects aswell).
The issue happens, when I either connect to a WLAN or try to activate the WiFi Hotspot.
After those triggers I also noticed that activating usb tethering leads to another crash.
After the crash I can enable usb tethering (did not try WiFi yet).
Are some of you guys able to reproduce this?
I am asking here because I wanted to install LOS but now I am not sure if I should proceed... (Bootloader still locked)
Btw: I've submitted the logs to Xiaomi.

[Q] Wireless issue

I've searched the forums for a similar issue with no luck, if anyone knows of a thread with a matching problem please provide a link.
My problem is that whenever I connect to my home network via wifi, I'm able to connect/disconnect a maximum of 3 times before wifi stops working completely. On the forth try, the phone will detect the network, try to connect and instantly disconnect. The only way I've been able to get wifi working correctly again is by rebooting the router, which also restarts the '3 connection' cycle.
I'm using a Netgear DG834G v2 and currently running Wolfbreak's latest version of CM6.1.3 but I've had the same issue with every other rom, including the official SE firmware, which leads me to believe that it is a router issue and not the phone itself.
Any help/suggestions would be greatly appreciated.
In your phone, go to WiFi settings and press options button, then select "advanced", in wifi suspension politics (or something like that) select NEVER, then download and install Blade Wifi Fix from the market (i don't know what exactly does but it will prevent WiFi disconnections and it really works), and you can try using (optional) this app to connect to WiFi, if the problem still persists i would rather think it's a router issue or something ._.
CescVicious, thanks for your help. I tried both of those apps but my wifi continues to disconnect. I'm leaning towards it being a router issue more than the phone and have posted the problem on the Netgear forums.
Thanks again.

X10i restarts while connecting to WiFi hotspot

Hi all,
I have a problem while connecting to WiFi hotspot feature. I have Feravolt v3 JB rom, Ferakernel.
I am able to activate the Wifi hotspot feature in the phone and its broadcasting fine until I try to connect from my laptop's wireless adapter. The SSID is detected in the wireless networks and when i try to connect, it acquires the ip address and as soon as I get the message 'wireless connected', the phone LED color changes and the phone reboots. I tried both pdanet+ and also the hotspot feature in the rom. both times the phone restarts. I did factory reset and tested hotspot feature before installing any other apps. still the same result. I also tried keeping the phone charged while connecting to hotspot. No luck. I am able to do usb tethering, reverse tethering without any problem. I did not overclock. Just using default settings that came with the rom. disabled sleep policy, kept the screen always on......
My only guess is that might be battery problem and if so any idea how to overcome this problem without buying a new battery.
Anyone had similar problem before or its a first?
Appreciate if someone can guide me if I need to enable or disable any feature.

Sony Xperia Z2 Tablet (SGP521) Wifi and Bluetooth problem

Hi all,
About a month or so ago I started to experience issues with with the Wifi and Bluetooth on my tablet.
At this stage I'm unable to switch on the Wifi or the Bluetooth. I'm only able to to use the cellular connection. When you try and enable the wifi connection is shows that it's trying to scan for a network, but it actually never switches the Wifi on. At times it actually pauses for a few seconds after selecting the Wifi option. Then at times it just doesn't do anything when trying to activate the Wifi via the quick pull down menu.
From what I have read it appears to be a hardware problem, but then I also saw comments that it might just be a software issue.
I was rooted at one stage and in my desperation I did a OTA update to the latest 5.1.1 release to see if that will help, but it did not.
When I was rooted I did a factory reset via TWRP, but that also did not work.
My device isn't under warranty anymore so RMA isn't really an option.
However I would like to check with the community if there is anyone else who had this issue and managed to get it fixed.
Is it a hardware or software problem or even a bit of both?
Would one be able to possibly replace the WIFI and Bluetooth radio in the Z2?
I normally use the Z2 for media consumption whilst at home over the wifi connection and would like to see if it can be fixed without costing an arm and a leg.
Your help or suggestion will be appreciated.

USB tethering and Wi-Fi hotspot randomly stop working

I use the USB tethering and Wi-Fi hotspot a lot, and after the latest update (PKL-L01C432B371) they sometimes randomly stop working.
The phone suddenly displays the honor logo, shuts the service, and then returns to "normal".
I think it has only happened to me when the phone has been either plugged to the pc or a charger.
Has anyone had similar problems, or does anyone have any ideas what to do?
Maybe reverting to the last update could work.
@JukkaJaF Yes I have faced a few random reboots like that, but I don't use hotspot or tethering, maybe its a stock kernel issue, try using hotspot or tethering after flashing a custom kernel or a custom ROM.

Data connection not working when connected to wifi

Hi all,
i've got this big problem and i dunno how to solve it.
Stock rom, MIUI 12.0.3, no root, developer options active.
I ran into this annoying bug months ago, while trying to get my car's android auto working with my phone without using usb cable.
I managed to connect my Mi 8 lite with the car via wifi connection; made it enabling Android Auto developer options (otherwise it wolud let me connect only with cable). Unfortunately once connected everything doesn't work, because there is no data: while wifi is on AND connected, my phone doesn't "want" to use my mobile data, even if i force data use by setting "mobile data always on" option in developer options.
I noticed this is not a problem of my car's infotainmnet, infact it happens also if i connect my phone to my wifi network unplugging phone's line cable (and so internet data ) from my router. Also in this case, with phone mobile data always active, my phone will stay connected to my wifi (which has no internet) and won't use my mobile data.
Does anyone have any idea/suggestion or know what i'm doing wrong?
Thx in advance for reading
This topic is discussed here: https://forum.xda-developers.com/t/...iui-while-aa-is-connected-wirelessly.4252187/
But no widely working workaround yet.
