Installing XBMC on Acer Aspire Revo 3700 (Part 2)

This tutorial follows on from an earlier tutorial that can be found HERE.
To get Wifi working, follow this procedure:

Once XBMC has been installed, boot in and switch to the terminal by pressing CNTRL ALT F2

Install wpasupplicant by typing:
sudo apt-get install wireless-tools wpasupplicant

Install the driver for the RT3090:
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:markus-tisoft/rt3090
sudo apt-get update
sudo apt-get install rt3090-dkms

Install wicd-curses (This will manage your newtork connections)
sudo apt-get install wicd-curses

Reboot by typing sudo su the reboot now. Once the computer has booted, type wicd-curses

You will notice that during the installation you will get an error: starting network connection manager wicd failed.

Now encrypt your network passkey with the following:
wpa_passphrase your_essid your_ascii_key

* replace the information with your own login details. For instance, my network (or essid) is called homenet, and my wpa passkey is monkey. So I would have typed in the following:

wpa_passphrase homenet monkey

The result should be something similar to the following:

network={
ssid="homenet"
#psk="monkey"
psk=ffe1b80746215def132a6afa2f192c90f5bed672b5793f17362086a7624ebe9d
}

Notice the last line. This is your passkey displayed in a hex value. You will need to write this down.

Now we have the network and key encrypted we can start adding this information to the interfaces configuration file:
sudo pico /etc/network/interfaces

Add the following lines of code, the wpa-psk line should match the result from wpa_passphrase:
auto wlan0
iface wlan0 inet dhcp
wpa-ssid Wireless Home
wpa-ap-scan 1
wpa-proto WPA #RSN
wpa-pairwise TKIP #CCMP
wpa-group TKIP #CCMP
wpa-key-mgmt WPA-PSK
wpa-psk ffe1b80746215def132a6afa2f192c90f5bed672b5793f17362086a7624ebe9d
Hit CNTRL X to save this information.

Now we should restart the networking services:
sudo /etc/init.d/networking restart

By typing ifconfig we can validate that we’re connected to the network.
