Il mio problema preciso è come quello descritto in questa pagina :

E neanche lì hanno trovato soluzione ,credo.

"ya, sometimes, both computers are online at the same time. one is a laptop with its own inside wireless equipment, another pc has this usb plug in wireless thing. so sometimes, only one computer can connect online, another one is super slow, almost zero connection. sometimes, both of the computers have good speed.
it is so random. so i don't know if it is because of the network outside of the home. or it was because of the wireless connection inside the home?"

Anche io col pc desktop ho "usb plug in wireless thing" e nella ps3 ha il "its own inside wireless equipment" wireless di tipo 'G' come la chiavetta che ho.
