Hi! After trying OpenWRT - Kamikaze 7.06 was nice, but 7.07 sucks (don't have the packages I need, etc.) - so I switched to FreeWRT and I like it (esp. the Imagebuilder via Web ;).
So 3 of my 4 APs are Kismet drones (yes I am a _very_ paranoid
person) to monitor the "air" around my AP (Currently running
on an OpenBSD host but I will switch to a AP with FreeWRT -
on an Asus 500g Premium soon. The AP will do the assoctiations
and the important part - IPsec - will still be handled by
the OpenBSD system).
On the Linksys WRT54-GL Kismet don't do channel hopping, although
it reports it. No problem ... known issue for me (OpenWRT has
the same problem) so I do channel hopping by myself in a background
script. So far so good.
But as the subject indicates there is a minor problem.
iwlist says the card will do 14 channels:
[EMAIL PROTECTED]:~# iwlist eth1 channel
eth1 14 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Channel 12 : 2.467 GHz
Channel 13 : 2.472 GHz
Channel 14 : 2.484 GHz
Current Channel
As I live in Europe (Germany) it is perfectly legal to
use frequencies above 2.462 GHz (channel 11).
But if I try to set a channel above 11 it returns with an
error saying:
[EMAIL PROTECTED]:~# iwconfig eth1 channel 12
Error for wireless request "Set Frequency" (8B04) :
SET failed on device eth1 ; Invalid argument.
As far as I know the (US american) FCC regulations the prohibit frequencies
above 2.462 GHz (channel 11) but this is a "european model" and in the
european countries (Germany in this case) the FCC rules do not apply
and it is perfectly legal to use frequencies up to 2.484 GHz.
The original firmware crap allows to use channels up to channel 13.
It seems to me that this is a driver bug. It also happens on OpenWRT Kamikaze
7.06.
(See my ticket on the OpenWRT - https://dev.openwrt.org/ticket/2043)
Is it possible to fix this? I am suspicous about the missing channels.
I can feel the bad guys crawling around my APs on channel 12-14 ;)
So long and thanks for your help,
Andreas.
