WPC300N linksys vista drivers not accepted in Vista

Hi,

I have been trying to get a linksys WPC300N wireless notebook adapter working on my Acer 9300 laptop.

The problem is the Vista drivers from the Linksys website do not update in windows vista. Vista says:

"The best driver software for your device is already installed"
"Windows has determined the driver software for your device is up to date"

The windows drivers are from 6/21/2006 version 4.82.28.56

The linksys are from 1/27/2007 version v4.102.15.56

The windows drivers do not work with the wpc300n well at all. The native wireless g (Atheros) picks up a signal at 85% and with this card it picks up the same signal at 15%.

As I need the distance and higher speed of the N router I can't use the internal wireless module and need to use an external card.

I contacted Acer and Linksys about this and each said it was not their problem. I called microsoft but since Vista was bundled they refused to help me unless I pay them $59 to talk about it.

It's apparently a vista issue as it insists on using its own drivers for this card.

Anyone have a suggestion of how to force Vista to update a driver?

Thanks
