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

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?

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