Note :if i put csco21.sys in systems32/driver my laptop got freezing right way.

Do you have other wireless NIC installed (other than the 350)? Can you install driver alone?

[KhangVie1]

I really don't know what happend . it's working really good before i format and reinstall windows . I have 2 cards . the old card 350 still working good. The new card A/B/G can't install driver either way it still freezing at file ..csco21.sys. I have to turn off the power of comp. then turn on again. If I put the new wireless card on it freeze right away.

If you install the Aironet Desktop Utility (ADU), ADU may compete Windows resources with other services/application. I suggest you to install the driver only. If that's still fail, do you install the same CB21AG card on other laptop?

[KhangVie1]

i tried both ADU and Driver Only it is still fail. But i didn't try with other laptop . I will try with other laptop then i will let you know . thanks

[KhangVie1]

Yes, It works for other laptop . But not my laptop . :)

You need to open a TAC Service Request. We need to get Development Engineer involved.
