I tried both on a stanard desktop PC, with 2 NICs, and a laptop with wifi+wired NIC.
Both times, the installer seems to break the internet connection somehow.
If this was fixed, I think my install would be flawless. I actually finished the desktop-install by doing ifup/ifdown on eth1, during the install. It then actually succeeds in continuing, even though a few packages in the middle failed downloading. I guess they got picked up in another later run.
