You could possibly try getting hold of a copy of the office RC, build 7100. It has a much MUCH larger driver
database & could solve your issue. Up to build 7068 I had to manually install my wireless driver for my laptop, now i get the connection screen before hte desktop has even been set up.
Might be worth a try
P.S by posting here you do at least have access to the net, hopefully some1 might be able to download the RC from Microsoft for you
