Hi
Just managed to configure AES-CCM encryption between three wifi devices in=
=20
adhoc mode and every thing seems to work fine.=20
I also found out that "ap_scan" must be set to "2" before it works.
Looks like the man page needs a small update:
ap_scan
Access point scanning and selection control; one of 0, 1
(default), or 2. Only setting 1 should be used with the wlan(=
4)
module; the other settings are for use on other operating sys=
=E2=80=90
tems.
mode IEEE 802.11 operation mode; either 0 (infrastructure, default) =
or
1 (IBSS). Note that IBSS (adhoc) mode can only be used with
key_mgmt set to NONE (plaintext and static WEP), or key_mgmt s=
et
to WPA-NONE (fixed group key TKIP/CCMP). In addition, ap_scan
has to be set to 2 for IBSS. WPA-NONE requires proto set to W=
PA,
key_mgmt set to WPA-NONE, pairwise set to NONE, group set to
either CCMP or TKIP (but not both), and psk must also be set.
