I recently bought a new Linksys E3200 router, and after much trouble, got it working, but I can only connect to it via Static wireless settings in my Connections Manager. I want it to be DHCP (Automatic), but then it automatically disconnects.
Also, I edited my /etc/network/interfaces to include:
auto lo iface lo inet loopback iface eth0 inet dynamic
Which causes me to receive the warning "Now booting without network configuration".
