I am new to Linux. Immediately encountered the problem of very weak wifi signal, that i haven't on windows.
I've already seen the solutions for HP laptops, and none of them worked for me. Tried to change kernel as well (I heard that 5.15 version is kinda buggy in this context), but still nothing.
I got following output for lshw -C network command:

I thought that updating WiFi driver would help, but saddly there's no version I can update for.
I would be incredibly grateful if someone could help
UPD 1.
Result of the terminal command: nmcli device wifi list is following. Where Androidha is my phone on which I turned on the hotspot and I literally placed my phone on the laptop, and it's still, not even close to "strong signal", the phone itself is connected to one of these other WiFi. Two other routers are in adjacent room.
