Comment 6 for bug 1231778

networking in lubuntu 13.10 doesn't work for me either. No ip address with wifi and with eth0 (usb to ethernet, see dmesg1.txt). lubuntu 13.04 works perfectly (same router, same ssid etc.)

I haven't tried gsm, though.

I disable ipv6 temporarily ( sudo /sbin/ip addr del <ipv6address>/<prefixlength> dev ethX ) but it had no effect on the bug.
