Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

Do the same with the following four commands:

Code: Select all

rfkill list all

Code: Select all

iwconfig

Code: Select all

lsusb

Code: Select all

lspci

Two things:

1. Try to undo the soft block like this:

Code: Select all

rfkill unblock all

2. Disable power management for your wifi:

Good to hear!

The wifi power management issue is probably unrelated, but turning it off improves wifi quality in most cases. So I advise to do that anyway. I always turn it off on my machines as a matter of course....
