8.04 updated network manager equals no PAL 2.0

Running Ubuntu 9.04 remix  I could not connect to PAL 2.0 useing the
network manager as discribed on the Purdue Linux Group's Airlink
page.  So I down graded with the install disk that came with my Dell
Mini 9 back to 8.04.  I could now connect to PAL 2.0 with the steps
found on P.L.U.G . 's page   Then later that month software update
gave me an updated network manager simular to the look of 9.04's
network manager  and with simular results for PAL 2.0 connecting

symptoms:
PAL2.0 instructions are found and immediatly connected too
i delete instructions as a connection and try connect to PAL2.0
This procedure worked when done and shown to be by an ITAP person in
the ITAP helproom (useing 9,04)  in the basement of Stewart, but could
not be duplicated anywhere else even after I went back and had her
show me again.  hope i discribed my problem well enough.  thanks for
your time.
