Weird. I have no trouble with DHCP via the wireless interface, I both wired and wireless networks depending on whether I'm at work or at home. I always get my lease renewed without issue using windows. Linux is a different story all together, dhcp has never worked there for me, but I'm ok with that. I'm very happy with the level of communication from Parallels, I'd say they are one of the most responsive software companies I know of. Imagine guys, they could be like the Skype mac team !
