I have a similar issue with the wi-fi. I've tried quite a few ROMs and it just won't start - 'unable to start wi-fi'. I keep reading about having to turn on the USB host option and then turn on the wireless, but that doesn't work either.Again, blue charge light, top USB and silver plastic shell.I have a ROM from tabletstoreuk.com that is pretty quick and everything else is working well, and at least the wi-fi option failure doesn't bring the system to a grinding halt.I'll be taking it back for replacement in a week or so unless anyone can recommend a fix.
