I have the same problem. eth0 works fine with DHCP, wlan0 (RT5390) does
not work. If I put static IP information and do not use DHCP wlan0 works
just fine, so it does not seem to be a driver problem. I also tried the
proprietary drivers, but that did not change anything. If you need
further information about my machine please contact me.
lshw with the current manual IPv4 settings on wlan0:
