wireless on aspire 3630

[Norman Silverstone]

I have installed Ubuntu 9.10 for a friend on his Acer aspire 3630 and,
with the exception of the wireless connection, all appears to be OK.
There is no icon for wireless monitor on the top panel nor is the icon
in the 'add to panel' list. I have not been able to find anything I can
follow on Google so would someone please be kind enough to advise me on
how to get the wireless to work.
