Hmmm...well, I installed Peerguardian 2 on my computer, and I also limited my sisters max upload to 100 kb/s, and did the same on mine...and now whenever she's using BT, it doesn't slow down. HOWEVER, there will be periods in both of our connections where for whatever reason, we won't be able to connect to anything. Tried Google.com, yahoo.com, the AIM client, MSN.com...and can't connect to anything. After rebooting, or just waiting a while, we'll get full connectivity again...this is really odd. She doesn't use any IP blocking software, so I doubt it's that. She uses WinXP service pack 2 and AVG, which are really the only things that differ in our setups...help!
