"You may wonder whether Hackers need expensive computer equipment and a

Hi,

I am trying to set up a 802.11a  network with 6 nodes. Is it ok if I
disable broadcast of beacon that takes place every 100ms. I dont need
BSSID or ESSID. I can preset it. Are there any other repercussions
beacuse of these changes ?

Thanks
Prasad Hegde

FYI

Trunk version r2598 is the last version that works for me with
Fedora's 2.6.22.1-33.fc7 kernel.

r2611 issues the following errors during compilation:
/root/Desktop/madwifi/r2611/net80211/ieee80211_linux.c: In function

r2619 and r2620 compile, but crash the kernel upon module insertion.


If you'd like me to do any followup on this email, please let me know.

Hi,

I am working with Mad-wifi and am new to the mailing list.. I had some doubts
and would be highly obliged if anyone could help me out..

I am trying to incorporate channel selection in the driver code as a part of my
experiment.. I want the driver to select the channel with minimum interference
in Ad-Hoc wireless mode.

1. Can anyone please tell me if there is any parameter which the driver already
uses to sense whether the channel is busy ?

2. If I want to use any one parameter to measure interference and then select
the channel based on this parameter, to which all files must the changes be
made? That is, what all files are run when the ad-hoc is set up and channel
selection is made?

Please help asap.. Thanks a lot !

Cool, thanks!

So we will need to build a "lookup table" that allows chipset
identification based on the various revisions we can get from the
hardware. Is that correct?

Bye, Mike

The driver requested an IRQ but didn't get it.

OK, I understand it's a non-transparent bridge.

I don't see any evidence that the problem is in MadWifi.  In fact, I
tested MadWifi with a non-transparent bridge (RB14), and it worked fine.

If the driver cannot get an irq, it's correct for the driver to refuse
to support the device.  The interrupts are managed by the kernel outside
MadWifi.
