sorry to report that my previous message was hoax. the ip address is still not assigned during startup. I have to manually deactivate and reactivate the interface in kde system-settings. a simple "sudo ifconfig eth0 down" and "sudo ifconfig eth0 up" is not enough.
I tried it with wpa and without. Any logfiles I can provide? -- no ip address after boot https://launchpad.net/bugs/62156 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
