What To Do If Ethernet Port Is Not Working. Check that Ethernet LAN is enabled in BIOS. The LAN LED and WAN LED should both be lit.
I have checked with several cables. When the ethernet cable is connected the amber light flashes once briefly. Where can I find the interface box in an apt.
If there are no lights it could be a hardware failure you could get either a USB network adapter as a replacement or Contact HP to have it either repaired or replaced.
Email to a Friend. Go back to Windows. In the end I opened the Ethernet port RJ45 socket in the wall and a couple of the cables were not punched down correctly - punched in and it is all working. Right click the Ethernet adaptor and click Update Driver Software.
