Output of "route" on it:

Destination 192.168.0.0 Gateway * Genmask 255.255.255.0 Flags U Metric
0 Ref 0 Use 0 Iface wlan0

Output of "route -A inet6" is much longer - see
http://paste.debian.net/1001796 - note that this is "as is", I haven't
concealed anything.

I am in control but it's a case of "can it be done and if so how?".

Not tried that yet but I will, a bit later.
