Last week, I changed the name of our wireless network. The new name is broadcasting fine. Tried to connect to it from a few different devices, and I get a "Can't connect.." message on the computers, smartphones just try to connect for a few seconds and then nothing. I have tried forgetting the network, then reconnecting, still nothing. Changed the SSID back to what it was, still can't connect. I figured the wireless was shot in the router (Belkin DSL-2750B combo modem/router). Customer service sent me a new one. All was good at setup. Changed the SSID (kicking myself hard now) and same issue!
So I think the hardware is ruled out. I have changed the SSID multiple times in the past and never had this issue. Even after factory reset, I cannot connect to the default SSID now. Have tried standard password entry and WPS methods to connect. Have disabled security entirely with same results.
One strange (to me) thing I notice, is the router is broadcasting a lot of packets over the wireless interface, even though nothing is connected. Not sure if this is normal or not.
I am totally lost on what to try next. Shouldn't every setting change back to default after a factory reset? Anyways, I would be very grateful for any ideas from the community.
