I rebooted my router because my internet was getting super slow and the router hadn't been restarted in quite a few months. However it refused to work after the restart, all the proper lights would turn on but it would not broadcast wireless nor would it be detected if connected by Ethernet, so I couldn't even go to its settings page; nothing showed for default gateway
in ipconfig

I tried resetting it again and also reset my modem and checked all the cables. Currently, I'm using a spare router in the exact same way and everything is fine. I don't get how I bricked my router, it is a dlink dgl 4300 and its firmware is updated and I've restarted it before and never had this issue.
