If after you suspend an alienware machine, the network is down, try this:

If this works:

echo 1 > sudo tee /sys/bus/pci/rescan
sleep 10s
sudo systemctl NetworkManager restart

create a script for it patch_alienware_no_networking_after_suspend.sh

echo 1 > /sys/bus/pci/rescan
sleep 10s
systemctl NetworkManager restart

Then you need to add that to the resume trigger

Create /lib/systemd/system/alienware-resume.service with these contents

[Unit]
Description=Rescan pci bus to recover network cards after resume
After=suspend.target
After=hibernate.target
After=hybrid-sleep.target

[Service]
ExecStart=/PATH_TO_MY_SCRIPT/patch_alienware_no_networking_after_suspend.sh

[Install]
WantedBy=suspend.target
WantedBy=hibernate.target
WantedBy=hybrid-sleep.target

now install the service:

sudo cp /home/jonny/Projects/patch/bin/patch_alienware_no_networking_after_suspend.service  /lib/systemd/system/alienware-resume.service 
sudo ln -s /lib/systemd/system/alienware-resume.service /etc/systemd/system/suspend.target.wants/
sudo ln -s /lib/systemd/system/alienware-resume.service /etc/systemd/system/hibernate.target.wants/
sudo ln -s /lib/systemd/system/alienware-resume.service /etc/systemd/system/hybrid-sleep.target.wants/

and enable the service

sudo systemctl enable alienware-resume
