Why do some routers take forever to access the configuration?

I have experienced with Netgear routers, so far all with built-in wireless access point. Most of the time they wouldn’t let me in. It keeps saying waiting for response. With some of them it would help if I reset the router. It seems that the router would respond if it is not long after reset.

The router in my office used to have such problem, now the problem never happens again. I wonder if it is because I often access the configuration.

I would love to hear comments.
