I tried to hock up my wi-fi network and have a problem:
my wifi is set to wpa2 and here are some symbols like %@/...
Input on TV network setup screen is limited to letters and digits only and i can`t connect my router. So i changed my wifi password, got TV connected, but i`m not happy with this solution - my network is less secure now...

I haven`t found any file on rw areas where the key is stored so i guess it should be somewhere else...(EEPROM?) I would enter my passw manually if i knew the place (and method).
