My ATV2 was JB with fw 4.2.1, and upgrading to 4.3.1 was a bloody headache for some reason. Anyway, I successfully upgraded to 4.3.1, without JB. However, when I try to connect to my wireless n network, which it never had a problem connecting to just before updating, I'm getting error -3914, and will not connect. It connects to the wireless G no problem, but I have some rather large videos, and wifi G will not suffice. Does anyone have any idea as to what this error means? I've searched tirelessly, and the only thing that comes close is error 3194 for ipods and iphones, in attempts to downgrade firmware, and its an itunes error. So not even close to my problem. Any thoughts would be greatly appreciated. Thanks!
