I'm using wl0 in client mode; it gets its address via DHCP, but doesn't seem to pick up a DNS server entry. I'm guessing that this is a config problem, not a problem with the DHCP server...

wl0 ends up being the "wan" interface - I don't have an ethernet cable plugged into the wan port. /etc/config/network has and entry for wan

config 'interface' 'wan'
        option 'proto' 'dhcp'
        option 'ifname' 'eth0.1'

which doesn't mention wl0 ... but it works.

What am I missing?

Thanks.
