Look in /etc/udev/rules/ and, I think, 70-net.something. The MAC address for the old machine is probably listed there. You want to replace that with the MAC address of this machine's card. The Ubuntu installer can set up wireless networks just fine. I don't know what it will do on a re-install to change an existing config. It may leave the old one in place, thinking that it is the config for a piece of hardware that is temporarily absent during the re-install. Or, it might overwrite the old config with the new and correct one.
