Wireless problem

Okay...so I have a major problem with either my wireless card or my router (much less likely). I have Vista 32 bit home premium, and an intel wifi 4965agn. When I connect to my network, sometimes it says "unidentified network" after it identifies my home network. When it gives me this message (it is technically connected), I cannot access the internet OR my router. This only happens at home. When I goto school, I can immediately connect to the school's wireless network. I can't find anything on google about this. Any help? <3

From the sounds of it you have not set a network location for your home network yet.

Start -> Network

ensure that the network has a zone. (public or home)
