Hello. Noob here, so please bear with me. I have a WZR-HP-G450H that's been working like a charm as a wireless AP. I've had it set to channel 1 since I got it, but that channel is getting crowded, so I tried changing the channel to 4. When I applied the change, the entire wireless system went down. Not even Android's excellent wifi analyzer app could find a trace of the router at all, even when I was standing right next to it. I power-cycled the router Still no joy. When I switched it back to channel 1, siddenly it was online again.
It seems that the only settings that will work are either channel 1 or AUTO. Setting the channel to anything else brings the whole wireless system down.
Am I doing something wrong? Is this a hardware problem? Appreciate any help here, please. Channel 1 around me is getting clogged, but 3 and 4 are still open and I'd like to use either one,
