I have comcast high-speed internet. I used to have it (before it was taken away for *cough* *cough* "reasons") and could use peer-to-peer programs (i.e. Kazza Lite, Bearshare, etc.) without a hitch. Now, after I got it back, none of them work. I can get on the Internet fine and all, just can't "log-on"; it just endlessly searches for a connection. I have a Linksys Wireless-G Broadband Router (model# WRT54G). Someone please help me!
