Maximum PC

I recently upgraded my DSL connection fairly substantially from what it was before. I went from 1.5 Mb/s down to just slightly under 5 Mb/s down. In doing this though, I get random disconnects all the time. It'll last between 5 minutes to 20 minutes at that connection. Last night it disconnected and reconnected at 4.5 Mb/s down and worked fine the rest of the night for me which consisted of around another five hours or so of gaming and chatting on the line. So it seems the slower speeds are more stable.

Right not, connected at exactly 4,928 bits down, my line attenuation is 48.5... I've read that, that number is in the "good" category, but it's just there. Could that be causing my problems? Calling my ISP is basically a lost cause because they seem to know nothing.

Any idea, or information you guys can offer would be a great help. I had zero problems of disconnects before this upgrade, so my initial guess is that the speed is probably to high for our lines.
