The drivers are messed up. For example I can see and connect to any WiFi router BUT my own Linksys G (WRT54GS). Yet, my laptop using a Linksys WiFi G card can connect to it fine. Interestly, the Ferrari can see a very good signal to my Linksys, but will NOT connect even if I leave it wide-open. I even called Linksys about it asking about compatibilities issues. But they say the broadcom WiFi chipset shouldn't cause an issue at all.
Here is where it gets strange. The moment I run DXDIAG, I notice that it will connect to my Linksys. But the connection is VERY VERY slow, think 9600 baud connection slow. Yet again, the drivers report a perfect signal from my Linksys (it had better as I'm 5 feet away from it). So I rebooted my laptop....same issue. It will NOT connect to my Linksys untill I run DXDIAG.
Ok, so now it's safe to asume that it's a driver issue and not a hardware compatibility issue (so I would think). I even turned off PNP network support on Linksys thinking they drivers on my Ferrari might be acking up with PNP and DirectXs Direct Play networking stuff (because it connects right when I run DXDIAG).
Too bad Broadcom doesnt have generic drivers available for the WiFi stuff like they do for the networking chipsets.
