no wifi after suspend

[ori0n]

Every time I suspend my laptop, on resuming I am unable to connect, there are no available networks and I need to reboot.

I tried this, this and this, but no one worked.

I hope this info are enough, otherwise please ask me more.

I would see if

Code: Select all

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf && systemctl restart network-manager.service

Helps any

[ori0n]

Nope
But thank you for the answer.

[JeremyB]

Do you have any idea why wifi isn't working after suspend? Check rfkill list; dmesg | egrep -i 'ath|wlp60s0 after coming out of suspend

[ori0n]

I run your command:
Before suspend:

vimdiff after before:

I see the output is different, but can't interpret these results.

After suspend is the wifi driver even loaded?

Code: Select all

lsmod | grep ath
