I have this same issue, how strange. I was looking for an answer to this problem. The only time my internet connection drops is when I am running Limewire .. I have lime wire pro, the latest version. Limewire has always worked great for me until I networked my 2 PCs now everytime it drops the connection, sometimes after a few minutes, sometimes hours. I also have a wireless D-link router, cable modem, and Win XP home edition. I hope there's help!
