To summarise, wlan0 got up and going with the new card no problems, ping worked fine but the webdt wouldn't start loading the orbiter stuff. Couldn't get the Tablet CFG to run manually.
Tried installation on another webdt with the Cisco card and no security, installed fine and orbiter came up.
Changed security to WPA2
Reinstalled again on original webdt, made the interface file changes with DHCP and WPA password, and it all started loading and now orbiter is on there!
Will now try it on the second webdt to get it running on WPA2 but I have no idea what I did.
I thought it may have had to do with the persistent net rules or the cisco card was coming up as eth0 but........
Thanks a lot for the help.
