iwi or ndis for Intel Pro/wireless 2200BG

[Bakul Shah]

Which driver is recommended for Intel Pro/wireless 2200BG,
iwi or ndis?  I am using iwi and while not entirely stable it
used to work reasonably well including suspend/resume.  Now
it silently reboots the machine when I try to restart it
(when connectivity with the AP is lost).  I am running fairly
recent -current.  Thanks for any recommendation
