I'm on 1.23NA right now and it still drops sometimes.
I also have another problem with the router. I do ping test while I have no games loaded up and the ping has almost no jitter. After leaving the wireless on/connected for a long time, when I start up a game such as SC2 or WOW, the wireless jitter gets really bad. I would get like very low pings then all of a sudden a big spike on like every few pings.
I'm thinking about going down to 1.15
