I have a D-Link wireless N router that I've been using for only about a year. It has never dropped a signal or needed to restart for anything but all of a sudden yesterday it started dropping wireless signals but everything connected to it via the Ethernet cable was completely fine (no disconnects). Is it possible to have the wireless transmitting part of the router is defective but the wired parts work fine? I have tried power cycling and resetting the router multiple times already but same problems. Is it time for a new router (and this time a high quality one)?
