I find I get very a poor wifi signal in my living room with the Samsung Galaxy S2 (and not great with other devices either), so I have the wifi repeater Asus RT-N13U. http://www.asus.com/Networks/Wireless_Routers/RTN13U/ 

Using Wifi Analyzer, I can pick up both my wireless router and the repeater. As expected, depending where I am, the signal strength between the two varies.

However I can stand right next to the repeater, and see it at full signal with Wifi Analyzer, but the wi-fi icon on the Galaxy S2 is at 0 bars. When I tried to connect to the net, it ended up using 3G.

The repeater uses the same name, channel, security etc, because it just repeats. But I wonder why the phone only uses the main wireless router.

Any thoughts?

Thanks!
