thanks, here's some more info
Thanks for the quick reply Ken!
I pinged apple.com and msn.com as you suggested and the request timed out on both sites.
I also did an ipconfig /all but I'm not quite sure what to look for. I did notice that the primary DSN suffix is blank, as is Connection-specific DNS Suffixes for Wirelelss LAN adapter Wireless Network Connection.
So maybe it's a combination of Comcast and me.
Is there something specific I should look for in the ipconfig /all that could give you more information?
