LinuxCNC not connecting to 7i96S on 2.9.1

There's no option in the bios for power management. In order to install Linux I had to flash a custom bios by mrchromebox.tech

Have you tried a longer servo thread period?
 

Yes I did the maximum it allows me and still says "resource temporarily unavailable"

While installing Linux cnc it said two missing "non free firmware files" I attached a picture of one of the files it requested. I ignored it and continued and both Ethernet and WiFi connections work being connected to the Internet. Not sure if it's involved with the issues

Sorry here's the photo attached.

EDITED
To quick and glasses now working, so bellow is for wifi, not ethernet, as noted below by OP.
Thank you and sorry for the mixup .

The link is down, so what is returning the ping back?
Not sure if this is valid in later versions of Debian, but try
ifconfig wlp2s0 up

it says "bash: ifconfig: command not found"
