Hey gang -
I have a TR1A and TR1AP and got two MSI brand wireless cards, MP54GBT2.
The good: the card installed fine in both machines (one WinXP sp2, other Windows Vista beta) and works great. A cheap (~$40 ea.) way to add -g wireless capability. Easy install thanks to the great instructions here. Just required a couple of small phillips screwdrivers.
The bad: the bluetooth does not work. I ignored the warning that these were for specific MSI computer models, but have not been able to get them up and running with the BlueSoleil application that comes with the cards. There is a specific BT driver, but only for 64-bit WinXP. The rest have to rely on BlueSoleil?
I also got a pair of bluetooth mini antennas on eBay for about $8 each (incl. shipping). Sadly, doesn’t look good for getting it working.
After looking back, Zipzoomfly.com has the same card without the bluetooth for $30.
