I am trying to fix an issue with my Realtek NIC not using ASPM.

Apparently it can be fixed by running:
Code:
echo 1 | tee /sys/bus/pci/drivers/r8169/0000\:02\:00.0/link/l1_2_aspm
at least until reboot. Now, whenever I throw this command in the shell I get a "Permission denied".

Has someone else had this issue and any idea how to solve this or an alternative method to fix the realtek driver not going into ASPM?
