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

* give the interfaces some time to settle
sleep 5
* turn off diversity on the interfaces
