I am absolutely no expert in this field (have used hostap for less than a
week), but I first determined the ID of my card (which came out as NICID:
id=0x801b) using cmd 'hostap_diag wlan0'.
Then I found my NICID in this table:
and found the letter 'F' in the column of the Secondary Release Code ID. This
is for upgrading the station firmware which is probably what you are after.
Thus, I was supposed to use 'sf010704.hex' (found on
First I did a test run (-v):
prism2_srec -v wlan0 sf010704.hex
All looked good with the test run, so I did a real upgrade (-vf):
prism2_srec -vf wlan0 sf010704.hex
The 'rf010704.hex' (as opposed to 'sf010704.hex') is to be used for
downloading the new firmware in RAM (volatile mem) (this way you don't perform
a permanent firmware upgrade, so simply eject and re-insert your card to get
the old firmware back).
Also, have a look at http://trekweb.com/~jasonb/articles/hostap_20030727.shtml
This document helped me a lot.
