Earlier today the router got unplugged and plugged back in, and stopped working for a bit, but we fixed it and the wifi works again. However, my PC is connected to the router via ethernet (through a power-line adapter) and i haven't been able to get the PC's internet working again. I've tried flushing the DNS, using default IP settings for the connection, restarting the router, modem, and PC, using the network reset button, using the network adapter troubleshooter, updating my drivers, switching ethernet cables, using a different ethernet port on the router, and connecting the ethernet to the modem instead. I may have missed a few things i tried, but this should be most of them. Some of the errors I've gotten from the troubleshooter have been
"DNS server isn't responding", "The default gateway isn't available", and "the connection between your access point, router, or cable modem and the internet is broken" but the troubleshooter has also shown those issues as resolved sometimes, so I'm not sure if they're actually problems. I'm really just stumped and would like to get it working again at some point, so I'd appreciate some help.
