So, the problem is that my computer is not not connecting to the wireless network in my home. It will claim to connect, Airport will show full bars, and in the network diagnostics it claims it's working fine, but when I use any program I know of to connect to the internet it says I'm not connected. The wired internet works just fine through the same router. The wireless is working just fine for both of my housemates' standard macbooks, one of which is older than my pro and one of which is newer. I'm using an early-2006 model MacBook Pro, which I have upgraded to Leopard, and have downloaded all the updates. It works fine on my mom's wireless network and also on my college's wireless network. I moved off campus, and we got Comcast cable internet, and are using a D-link DI-524 wireless router, and this is the wireless network it is not working for. I checked various help pages for similar problems with macbook pros, and I attempted to try their solutions, but none of the directions for, say, deleting and re-establishing the wireless network seem to actually do that on my computer, and I have no idea how to attempt it. Any help any of you could give me would be very greatly appreciated. Thanks in advance!
