Galaxy S2-Having WIFI problem while using it.

Hello,
There is some error while using WIFI in my android phone. It doesn’t show any WIFI network. I have WIFI connection for internet access. But I am unable to find any WIFI network in my phone. I don’t know why it doesn’t show any WIFI network.
Give me solution please.

Hello,
Android phones like HTC,Samsung cannot connect to a adhoc network. if u don't use a router(like swift etc), your android phones wont connect to WiFi.
