It's better to use iwconfig before ifconfig. This way, you go on the air
with proper configuration. Otherwise, you start as an access point with
ESSID "test" and then reconfigure the card to be a station.

Is it traffic between other hosts? It would be more interesting to see
the output of iwconfig at this point. It should show if the station is
associated (see "Access Point").

See the output of ifconfig and iwconfig. In particular, see if the
interface is still up and the card is still associated. Maybe dhcpcd
brings the interface down temporarily.
I think the rest should be discussed with your sysadmin if you don't want
to post the output of ifconfig here.
