Spelling: GHO-Wrap



* Draft ***

This Page outlines the steps we took to configure the new (Yawarra
http://www.yawarra.com.au) provided wrap units for GHO.

For the full details & pic's refer to the GHO-Wrap-Project Case Study
(coming in may after comissioning)

We had a running image of voyage linux 0.3 so we used
this image and copied it to the supplied 512Mb CF Flash cards.

One we set an ip address in the /etc/network/interfaces file

We proceeded with our wireless config.

We decided to use atheros 5212 based wireless cards (Ubiquiti) on our
unit but the cheaper a/b/g Wiston CM9 will work on this config as
well.

Here's our interfaces file (Draft)

GHO-North-wrap-1E:/# more /etc/network/interfaces

**********************start of file****************

* Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
* /usr/share/doc/ifupdown/examples for more information.

And here's out post interface startup file

more /etc/init.d/ath_init

**********************start of file****************

#!/bin/sh
#

* give the interfaces some time to settle

sleep 5

* turn off diversity on the interfaces

sysctl -w dev.wifi0.diversity=0
sysctl -w dev.wifi0.txantenna=1
sysctl -w dev.wifi0.rxantenna=1
sysctl -w dev.wifi1.diversity=0
sysctl -w dev.wifi1.txantenna=1
sysctl -w dev.wifi1.rxantenna=1

* set the distance control

athctrl -i wifi0 -d 25000
athctrl -i wifi1 -d 25000
