[Madwifi-devel] Trouble manually swapping AP's

[Joshua P. <jp...@ki...>]

Hello,

I have a computer with a Wistron CM9 mini-pci wifi card in it, and I'm
trying to manually force the computer to associate to a specific Access
point. After I run my script (pasted below), if I repeatedly run
"iwconfig ath0", it seems that the card has gone into a scanning mode
where it takes a while to settle on the channel I've selected for it.
Specifically, I see that the mode alternates between IEEE 802.11g, IEEE
802.11a, and IEEE 802.11Ta, with appropriate frequency changes. Even
when the mode says g, the frequency is usually not the one I want.

Am I doing something wrong, or is this the natural behavior of the card?
Is there any sure fire way to manually force a card to quickly switch to
a new AP with the same SSID?

Thanks,

Josh

Here is my script:

#!/bin/sh

echo switching to AP ${1} on channel ${2}

ifconfig ath0 down
ifconfig wifi0 down
iwconfig ath0 essid kiva
iwconfig ath0 key ccbbaa99887766554433221100
iwconfig ath0 ap 00:A0:F8:E5:CA:${1}
iwconfig ath0 channel ${2}
ifconfig wifi0 up
ifconfig ath0 up
iwconfig ath0
