I am having the same issue. I loose ability to access the router settings using the http://192.168.0.1 address, so I am forced to do a hard reset. I then edit the settings using the restored default address to my SSID. The router will function normally, and then I will loose setup access again (from network genie and browser) and know the problem has returned. It might be coincidental, but my VPN connection quits allowing me to connect through it to remote computers at the same time. The VPN connection will connect properly, but I am unable to see any of the servers I normally work on. After a reset, the connections will also begin working normally. Netgear was helpless, and going to the closet to reset the router every time I need to access settings or access a server thru VPN is getting very old.
Is there any chance that an update is being pushed down, or would this not effect the restored capabilities after a reset? An chance a firmware update could help?
