Internet loss on LAN

[Gyula84]

HI i have an ASUS ROG Strix G18 (2025) and i have a problem with LAN internet connection, on WIFI is working well and i tired an usb LAN device it also worked well. Flush dns did not help, driver reinstall did not help, i dont want to reinstall my windows 11 but i think it will not help. What can i do? Thanks

edited.: new windows install did not solve the problem so is it a hardware fault?

Sounds like broken ASPM implementation Check the settings in power plan
to be sure they're on power saving mode.
Unhide PCIe ASPM Settings
(CMD):
powercfg -attributes SUB_PCIEXPRESS ASPM -ATTRIB_HIDE
powercfg -attributes SUB_PCIEXPRESS LPM -ATTRIB_HIDE

Path: Control Panel → Power Options → Change Plan Settings → Advanced → PCI Express → Link State Power Management → Off

Registry – Unlock ASPM Settings:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\501a4d13-42af-4429-9fd1a8218c268e20\ee12f906-d277-404b-b6da-e5fa1a576df5
DWORD: Attributes = 0

Registry – Force ASPM Off:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pci\Parameters
DWORD: EnableASPM = 0
DWORD: EnableL1 = 0

Force PCIe to Max Performance (CMD):
powercfg -setacvalueindex SCHEME_CURRENT SUB_PCIEXPRESS ASPM 0
powercfg -setdcvalueindex SCHEME_CURRENT SUB_PCIEXPRESS ASPM 0
powercfg -setactive SCHEME_CURRENT

Flush GPU Driver Caches:
NVIDIA:
%ProgramData%\NVIDIA Corporation\Drs
(Delete nvdrsdb0.bin & nvdrsdb1.bin)

AMD:
C:\Users\YourName\AppData\Local\AMD\CN
(Delete gmdb.blb and cache files)

Verify with HWiNFO64:
Current Link State = L0
Link Speed = Gen3/Gen4/Gen5 (no drop into L0s/L1 mid-game)
