I have a MBP (2007 model) and i recently setup a home network. The router is a Belkin N Wireless router. My laptop is the main computer in my home. Now my Ipod Touch and my cell phone work just fine with my router; i.e they connect and i can surf the net and stuff, but my laptop will not get on the net once i disconnect the ethernet cable from it. It will connect to the network, but nothing after that. How can i solve this problem??
