Huh, don't know if this is unhappy coincidence or what but I had to reinstall UNR to get everything back up and running, and I no longer seem to have network connections...at all. I've just tried UNR, Moblin and Linpus and neither can connect over wired/wireless network, buggery. Edit: Fixed wireless in Ubuntu at least, seems DHCP isn't working for me at all for some bizarre reason (I'm at work, where I've tried two different routers) but specifying an IP worked a-ok Edit: Scrap that as well, I had two networks fail on me at the same time.
