wireless networks "device not ready"

[stevef]

I found references to disabling support for 802.11ax.
This hack seems to be suggested as a remedy for several symptoms.

Open the iwlfifi configuration file with an editor

Code:

sudo nano /etc/modprobe.d/iwlwifi.conf

Enter your password if asked

Look for this line.

Code:

options iwlwifi disable_11ax=1

If it is not present, use the down arrow to move to the bottom of the file and paste the line in (followed by enter) so it is on its own line.

Press 'Ctrl' and 'X' to exit the editor
Press 'Y' when asked 'Save modified buffer?'.
Press 'Enter' to confirm the file name

Reboot
