No WiFi problems here that I've noticed. I read somewhere that rebooting the phone while WiFi is on helps it stick and not drop. I've been doing that every time WiFi is turned off and on again and it seems to have helped. =)
I'm asking because people on the 4.2.2 ota have been reporting WiFi dropping problems on stock kernel. If this it the case I have a good idea of what might be causing it.
