MN-720 disables built-in wired networking - how to fix

This can't be that uncommon a problem, but I can't find
anything that addresses it.

You should be able to have the MN-720 wireless adapter co-
exist with a built-in wired network card, shouldn't you,
so you can be sometimes wired and sometimes wireless?

I just installed the MN-720 wireless G adapter on my Win2K
laptop, which already had a built-in Ethernet port. Prior
to installing the MN-720, the laptop was connected to my
wired LAN, all was fine.

After installing the MN-720, the wireless works fine (it
found my wireless router, I connected to it, I'm rocking
at 54 Mbps), but now my wired LAN connection is broken.
While not strictly a problem with the MN-720 per se,
installing it definitely caused this.

Can I get them to co-exist? How do I re-enable the wired
LAN? When I'm using it, do I have to do anything special
to switch between them (like pulling the wireless card
when I want a wired connection)?

Thanks,
dave
