[Madwifi-devel] Tweeking wireless settings

[Dan S. <da...@ad...>]

Hi,

I've googled for answers but turned up nothing, maybe you guys can
help....

I want to set the following options on the madwifi driver and wondered
how it can be done....

a) Force support for Long preamble only (for 802.11b compatability).

b) Set the Beacon period (interval) in ms for AP's and Ad-hoc stations.

c) Set the Beacon timeout for Stations, i.e. the number of beacon
frames which are lost before the Station assumes the AP is out of
range or has lost connectivity somehow.

d) Set the DTIM period (interval), as some VoIP phones only work if
the DTIM period is set to 1.

e) Propagation delay, i.e. extend the Ack-timeout for the PHY to
support long distance links.

f) Set the supported rates map so that transmit rates may be limited
using the supported rates field in the association request/responce
frames.

g) Setting the slot time to long or short, to support legacy 802.11b
stations, and improve throughput on 802.11g only 2.4GHz networks.

h) Transmit power attenuation through software, does this work at
all? or does it need work? I assume it only works on calibrated radio
cards, if at all.

Regards, Dan...
