I have a Netgear N450 combination modem/router. It worked great in my old apartment, but I moved somewhat recently, and it's become unreliable. I have to plug/unplug it daily as it drops internet on all my devices (phone, computer, Roku, etc) regularly. The issue is the router; ethernet works fine. I'm not sure how to diagnose the problem, or whether I just need a new router. Any advice would be appreciated!
