I couldn't find any reference to a new 2.2.12 firmware on Netgear but some Googling and creative URL hacking definitely finds that it exists for download. Can't wait to get home and give it a shot
This fix is particularly relevant to my interests "Win8/Widi 3.5.41.0, N6235,WiFi 15.5.7 TV screen error message or no screen projection" Given that I've had this issue and have N6235 hardware
