To connect your computer to the public computer ports at the bar in the 2nd floor entry area and in the Engineering Student Commons, your must have configured your computer to use DHCP (Dynamic Host Configuration Protocol). DHCP allows your computer to obtain a temporary IP address when connected to these ports. Using DHCP means that you do not have to register your computer with ECS. A machine with DHCP disabled will almost certainly be unable to access the UI Wireless eduroam network or the setup to get onto eduroam. You might have disabled DHCP to configure Domain Name Service (DNS) servers to connect to another network. To use the UI Wireless setup, enable DHCP so that the setup web site forwards you to the correct page. While using university DNS servers for setup is mandatory, once initial setup is complete, custom DNS servers can be enabled and used without issue.

(from Wikipedia) The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services. With DHCP, computers request IP addresses and networking parameters automatically from a DHCP server, reducing the need for a network administrator or a user to configure these settings manually.
