What seems to be happening is that the router isn't handling all the connection requests LW is making (incomplete downloads trying to start, hosts trying to connect, uploads being requested, and so on). Browser connections rarely need more than a few connections. You can cut down the connections by cleaning out the incomplete folder.

Too, USB ports on OSX don't seem to handle the many connections required for p2p. I assume you are using the ethernet port with the netgear?

btw, I set my prefs to NOT connect on start-up. Maybe that will help.
