To ensure my network infrastructure is not to blaim, I retested with the same machine but with 11.04. As expected, everything worked.
ip route list (on 11.04, after plugged in the wired network): 192.168.0.0/24 dev eth0 proto kernel scope link src 192.168.0.101 metric 1 192.168.0.0/24 dev wlan0 proto kernel scope link src 192.168.0.100 metric 2 169.254.0.0/16 dev wlan0 scope link metric 1000 default via 192.168.0.1 dev eth0 proto static -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/846320 Title: Wired connection does not take preference over wireless (regression 11.10) Status in “network-manager” package in Ubuntu: Incomplete Bug description: When there is an active wireless connection, and the wired connector is connected, network manager is responding by notifying that the wired connection is made and the icon changes from wireless to wired. In ifconfig, a IP-address is bound to ethX. But when trying to do any file operations (or other things), it comes clear that the wired connection is not used, despite the icon and notification. The wired connection can only be activated when the wireless connecttion is forced into disconnect. But then, the wired connection is not becoming active, only after re- connecting the wired connection. Maybe the last problem is related to this bug mentioned. If not, a separate bug should be filed. When pulling the plug from, the wired connection, the wireless connection does not becomes active automatically, like it did prior to 11.10. You have to force the wireless connection to get connected again.
