HELP please rb112 wireless issue

Help! Having problems configuring my rb112 to act as dhcp client over wireless. Mini pci wireless cards are Atheros chip set. I enable interfaces, run scan which
shows the wireless server(s), go to dhcp client and add interface and enable, do print and it shows searching. Neaver actually connects. After a while, if you try the
print command in dhcp-client, the board locks up for 5 minutes or so, then issues a diagnostic message about creating a diagnostic image.

What am I doing wrong??? I even flashed to the latest ver.
