I think I've probably got bittorrent covered now ... If you turn off UPnP, then most P2P software is not going to work - they need the incoming port forwarded to their PC. Because it is a new connection, the router will not forward it unless there is a rule telling it to. UPnP lets them set up the rule without having to log into the router. Without this, they will be able to download, but not upload. This has a side effect of drastically slowing their download speed. > > I've had two episodes of the router becoming inoperative in the last 48 > hours!

I have run into this more then once - the first symptom is that wireless shots down, or at least stops accepting new connections. I also find that the router tends to run cooler if you use the vertical feet (brackets) to stand it on end instead of sitting flat. You can tell it is getting too warm by feeling the bottom of the router. The end by port 4 tends to be the hottest.
