No - I'm aware of the WiFi issues from before, I've even setup a WiFi network with open access.
Only way I can currently connect to it is by putting it into WiFi configuration mode.
My Sonoffs which had Wifi problems were actually fine as long as I powered them using the 3.3v from the programmer (I.e. From my laptop's USB port).
They gave problems as soon as I ran them from the mains (these were basics).
So perhaps try powering them directly without mains?
