Tried to find the right forum, even found folks who were redirected to other product forums based on their NetGear product, hope I found the right one.
R6300 user (love it). Upgraded from Win7 to Windows 8. Everything great...except NetGear Genie displays red/disconnected and indicates internet disconnectd on the UI. Sure am connected though, both wirelessly via R6300 to surf and type this as well as wired for blu-ray.
Don't use the desktop genie. You don't uninstall it but either disable or set to manual in services and go into msconfig and stop it from starting up. I don't like the desktop genie IMO its a crappy program that justs adds eye candy and popups and thats it. I used the desktop geniew and it kept dropping my wireless just didn't seem to perform properly. Use http://192.168.1.1/start.htm to access your router and not bother at all with using the desktop genie and I've haven't had any problems with my wireless since.
Searching QoS and Address Reservation in "Search This Forum" is a asset of the R6300 if you got a bunch of Iphone/Ipad, game consoles and other comps hooked into the router.
