Software Update hangs Ethernet

[r.j.s]

I'm running 10.6.2 on a new MBP 5,3 ...

Every time I run Software Update, the Ethernet freezes. I can't connect to anything, not even the router. A restart fixes it, and so does turning my Ethernet settings from DHCP to Off and back, but that is annoying.

Anyone know of a fix?

Ok, so it wasn't just SU, and it started happening on the MB too. I think it was 10.6.2 that caused it.

I seem to have fixed the problem, as my ISP is wired Ethernet, but still requires a login through a web page. By setting up the connection as PPPoE, I seem to have fixed the problem.
