BT Voyaer 205 & Vista Need HELLLP

Hi

I recently got my self a Windows Vista OEM , i installed it and it was fine,

eccept now i cant get onto the internet.

Now on the BT site it says they dont have BT 205 Voyager Drivers for Vista. And iv tired installng the modem but it never installs, everytime the computer starts up the bt instalation comes up saying "reboot to compleate instalation" but it never happens.

Now iv tried using my wireless BT Voyager 1500 to connect via ethernet but it seems dnt have ethernet drivers for the motherboard (i checked in divice manager).

My Motherboard is the ASUS M2N-VM-DH and iv tried there site but the Vista network drivers dont have an instalation file in them.
can anybody help me with this problem.

-------------

Update,

I unistalled the non working drivers and reinstalled them. Now they do come up on device manager but it says "device succesfully installed but unable to run" so it has a yellow explanation mark by the device
