Get your endpoint: $ lspci ... 03:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01) ... = 03:00.0 4. Now you neet to edit your enable-aspm # You just need to modify these three values: ROOT_COMPLEX="00:1c.2" ENDPOINT="03:00.0" ASPM_SETTING=2 5. Now executing: vo-one@acerone:~$ sudo bash enable-aspm [sudo] password for vo-one: Root complex: 00:1c.2 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 3 (rev 02) 0x50 : 0x43 --> 0x42 ...
