Wireless Chipset ZD1211?

This guide is written for the SlugOS 5.3 release, if a newer release is out please update this to match changes.

### Install modules and stuff to make zd1211 dongle work on SlugOS.

# The ugly stuff with /tmp/r in the /etc/network/interfaces file
# can be uncommented to prevent the dhcp of the wireless iface
# from overwriting the DNS resolver - useful if the wired and wireless
# networks are on different subnets or on different sides of a firewall,
# as they are in my case.

echo "Please reboot, then you can type \"ifup wlan0\" to bring up the new network..."

Copy that script over to your slug and run the script, this will take care of setting up the device.

WEP

This needs to be completed by someone who has used WEP :)

WPA

These next steps will allow you to connect to a WPA encrypted network.

nano /etc/wpa_supplicant.conf

Note: I use nano as my text editor just replace yours with your favorite.

Fill the above config file with:

network={

    ssid="(YOUR_NETWORK_NAME)"

    scan_ssid=1

    key_mgmt=WPA-PSK

    psk="(YOUR_PASSCODE)"
}

Replacing the ssid and psk with the right infomation.

Final Steps

Reboot the slug and as the script earlier run:

ifup wlan0

Your slug should now connect to the network, if you want the wireless to auto connect at boot just uncomment the line in /etc/network/interfaces which has auto wlan0 dhcp in.
