Episode 1205 (1:20:30)

Eric from Hollywood, CA
Netis Wireless USB Adapter

Eric has free Wi-Fi in his neighborhood, but his signal is pretty weak. Sadly, he doesn't have access to the router. How can he use an extender to pass the signal along? Leo says that he'd ideally want to boost both transmission and reception, but without access to the router, he can't do that.

Eric can use a better antenna to pick up the signal and improve the reception. If he can't improve his laptop's Wi-Fi antenna, he can get a USB Wi-Fi adapter to replace it. Leo recommends for tips and hints on how to improve his reception. The USB dongle may be enough to improve the signal.
