How can I use Samsung Galaxy Ace to connect to Internet through PC? I have a Dataone Broadband connection.
No it doesn't. Infact I have never understood why people use USB with their routers. Ethernet is the best.
Linksys WAG120N is Wifi-N which is 104mbps WLAN.
BSNL charges you 1.5k for the Wifi version iirc. It is better to shell out 0.5k more and get a proper router from outside. The BSNL ones have really bad range.
Do this.
