    27 Usually the wireless connection appears on `eth1`. After some searching I discovered Ubuntu bug !#183968, [https://bugs.launchpad.net/ubuntu/+source/udev/+bug/183968 mac80211 "master" interface matches existent persistent network rules]. The issue turns out to be with the udev script that names the interfaces and the reason is the newer wireless drivers present two interfaces, `wmaster` and `wlan`. The existing Gutsy udev rule `/etc/udev/rules.d/70-persistent-net.rules` doesn't discriminate on the `type` attribute and therefore assigns `eth1` to the first interface presented, which is usually `wmaster` and therefore when the `wlan` interface is presented it can't be renamed to `eth1` as well and gets called `wlan0_rename`.
