The ASUS Z790-H 2.5 Gb LAN is not functioning or displaying correctly.
I experienced issues with my motherboard after installing a CPU for a contact frame. Despite initial satisfaction, the Intel LAN device disappeared from Device Manager after five months. No visible damage was found, and attempts to fix it—checking pressure, resetting BIOS, updating firmware, or using netsh winsock reset—proved ineffective. The BIOS settings still show the LAN adapter enabled, but network configuration tools failed with an error about missing device. I considered hardware faults since it worked previously. I also looked into a CMOS battery replacement, thinking it might resolve the problem, though I’m unsure if that’s the correct approach.
The energy-saving feature in Windows was restored after a fresh installation.
