Rif.: Nighthawk Rs200 - no WIFI after Reboot - Internet via LAN ok

Same issue here. I'm dealing with RS200 and firmware v1.0.1.60, and every time I reboot the router (by detaching the electrical plug), the WiFi disappears and the only way to make it work again is a factory reset. This behavior is almost systematic, so every time the electricity power grid goes off and on, I know the WiFi won't work anymore. For this reason, for now I switch back to an older router, but this episode is pretty unpleasant, especially considering this router in the high-end family of Netgear routers.

I don't know if this is meaningful, but I had configured the DCHP to work on address range that does not overlap to static IPs, and I haven't altered any option related to WiFi.
