I was told to try attaching (by soldering) an external aerial from an old router to improve WiFi. I very much doubt there'll be any more mods and certainly no more firmware - not enough memory and too low spec' otherwise. I've given up with mine and tossed it into the back of a drawer for now, replaced it with a full on media streaming device and use my tablet for Internet. MUCH better, no lag, no freezing, no dropouts. End of my involvement with the CX-01.
