Today I've noticed that my iPhone 3GS will connect to my home wi-fi but only uses my 3G connection. In my wi-fi settings it says that I am connected to my network with a strong connection, however my network connection icon at the top says "3G" rather than the wifi icon, a speed test app shows that my connection is a lot slower then it should be with a wifi connection, and my apple remote app tells me I can't use it because I need to be connected to a wifi connection (which is just a log way of saying I know I'm definately not connected, an yet my wifi settings say I am). Is this a problem with my iPhone or router? I've tried resetting my network settings and restoring my iPhone with no luck...
