== Network Connection == The embedded PC is using a '''Cisco Aironet 1220B''' which was hardware-hacked by Jake to accept power from the ATX power supply of the computer. This consists of 3.3V and 5.0V which, plus ground, come into it with a custom three-terminal connector. A '''Generic Realtek USB 802.11b''' interface, which is sub-excellent, is also available in case the Cisco is not working or if the robot needs to access an 802.11b network. The Cisco Aironet 1220B named wbr2 on the wheelchair associates to a matching Cisco 1220B named wbr1 at 2169 Mission. They use 802.11a to communicate on a dedicated channel. They use the default username and password for that platform. The embedded PC uses its ethernet port '''eth1''' to talk to the Noisebridge network via a connection to wbr2's ethernet port. The embedded PC is configured from '''/etc/networks/interfaces''' Also, Network-Manager which is the gui-compatible 21st century newschool network configuration system is been pushed to the side, possibly for good. The embedded PC is now configured to find the wireless network called '''noisebridge''' and take the internal IP below. === Noisebridge internal IP address === The robot's USB wireless interface has claimed an IP on the internal network of 172.30.0.50 === Access from outside 2169 Mission === Configuration of the firewall is done (thanks Jof), so that connections to the machine can be initiated from the outside world. This is important if people are expected to log in and drive it around from Germany or Singapore. === DNS entry === In the future someone will assign that IP address a '''DNS entry''' like robot.noisebridge.net
