Just today one of the ethernet ports on my motherboard stopped working. The other one still works but the blinking lights indicate 100Mbps mode even though speedtest . net shows 900+ Mbps.
I’m open to the idea of installing new drivers and BIOS… but it was working fine up until today so I would like to explore other troubleshooting options before that.
The port that is not working is the Intel I219V.
I don’t get on forums often, so if I left out some important information please let me know and I’ll be happy to provide it
Reinstall the driver. Maybe Windows broke them. There is a possibility of a port breaking on a hardware level over time, but given that both ports not working correctly I would guess the driver installation is broken.
Welcome to the forums!
Try and boot a Linux USB and see if the ethernet actually works and not a hardware issue.
Actually only the Intel I219V port is not working. The other one is still working.
Good recommendation, I’ll give it a shot
