 This probably isn't wi driver problem. For me sound similar to know
 Linux orinoco driver issue. Monitor doesn't work stable with
 firmware>8.x - previous linux drivers  had some workarounds for it.
 With 0.15 driver you can not turn card into monitor mode anymore. I
 have hermes chipset card and after downgrading from 8.72 to 6.06
 firmware monitor mode works with my Jornada 690 (netbsd hpcsh-port).
 From linux driver changelog:
 0.15rc2 - 28 Jul 2004
 * Monitor mode disabled on Agere 8.xx firmware - it's broken.
 Part of linux driver:
