Dead network after suspend quick fix

If you are experiencing a dead network after suspending your laptop, you can try the following:

Reloading kernel module

WIRELESS_CARD=$(ip link | grep wlp | cut -d: -f2 | tr -d ' ')
SSID=$(iwctl station $WIRELESS_CARD show | grep SSID | cut -d: -f2 | tr -d ' ')
sudo modprobe -r iwlmvm iwlwifi 
sudo modprobe iwlmvm iwlwifi
sudo systemctl restart NetworkManager
iwctl station $WIRELESS_CARD connect $SSID

This will reload the kernel modules for the Intel wireless card.

Restarting the network interface

sudo ip link set wlp61s0 down
sudo ip link set wlp61s0 up

Often the DNS resolver is not working after a suspend
