As a follow-up to that...
My roommate apparently found information on Ubuntu website somewhere (launchpad maybe?) that explained that the wireless driver(s) included with 9.10 were broken, and/or DHCP doesn't work properly with them, and the solution offered was to revert back to the wireless driver(s) or wireless components from 9.04.
I can't verify this personally, but that's what she said.
If 9.10 is now installed on the sons computer, I'm not sure there's a guaranteed, reliable way to "revert" the whole thing back to 9.04. You may need to do what my roommate did and reinstall 9.04 from CD.
Or, if you want to try to FIX 9.10, try folllowing jschiwal's suggestion and provide us some info about the wireless device(s) you're using, and someone will try to help you figure out how to get it working.
