I recently built my own pc. I got a linksys wireless adapter (WMP54G) which I got the correct driver for so my system recognizes it. Then, I tried to connect to the wireless network my family has set up in my home. The other 2 pcs (and 1 mac) on the network all connected to the internet just fine once they got onto the internet, but mine seems to have a problem. I took a screenshot of the issue: http://i110.photobucket.com/albums/n117/gebbethlord/screenshot.jpg
If anyone can look at that and recognize the problem, that'd be great. Ill try to answer any questions if you have them.
Thanks.

Edit: How would I get to where it shows all allowed IP addresses on my router?
