Thanks for your help. Success at long last :)

To recap:
1) I used the live cd and followd the instructions on the link given below
(http://ubuntuforums.org/showthread.php?t=419709). Found that the wireless
card was ra0 (not ra1). This worked as per the instructions. Later found
that i also had my ethernet cable plugged in and while the wireless card
was working, it was communicating via eth0!!!

Been away for a few days so could not continue until tonight

2) Redid the live cd trick, this time with the ethernet cable unplugged
and wireless=>ra0. Success.

3) Did fresh install. Repeated using command line as suggested and
wireless=>ra1. Could get signal from AP. Could not ping router. Tried a
few tricks, and only succeeded in getting error messages and lockup.

4) Did fresh install (again). This time entered directly into
/etc/network/interfaces. Used ifup to restart wireless card. Got success
but with error messages. Noted that the main one was lack of DNS. Used
#echo "nameserver x.x.x.x" >> /etc/resolv.conf (have local DNS server)
SUCCESS!!!!

5) Did reboot to check that it came up again after reboot and again success.

So, thanks very much for your help. (Now onto next challenge hehehehe)

Ken
