The surge disrupted the Ethernet connection.
The surge disrupted the Ethernet connection.
I’m looking for some advice before moving forward. A recent power surge destroyed my modem, and I received a new one but noticed my Ethernet isn’t working—no display in Device Manager or network connections. The BIOS confirms it’s enabled, yet turning off the power supply didn’t make a difference. I’m guessing it’s damaged, but an article suggested removing the battery from the motherboard for a few hours to see if that helps. Any suggestions?
It will reinitialize the BIOS. However, since you didn’t adjust the BIOS settings after the surge, it’s unlikely to help much. It seems the surge likely damaged your Ethernet connection. If the rest of the motherboard is functioning fine, purchasing a PCIe network card with an Ethernet port would be a practical solution. Probably won’t cost much.
Ethernet seems to be failing, likely due to a lightning strike. WiFi functioned normally, but the main router ports stopped working and the secondary AP was destroyed.
I haven't been using the Ethernet bypass in my UPS yet, but now I'm considering doing so.
