St Edmund's College, Cambridge

St Edmund's College operates a wireless network available to all College members who have a computer with a wireless network card which uses the 802.11b or 802.11g standards (also known as Airport or Wi-Fi). The following information should help you get started using the network.

Current coverage

Full coverage:
The top floor of the new Library Building, the Norfolk Library, the CR and Bar area.

Partial coverage (not guaranteed):
The SCR, Huddleston Room, Okinaga Room and Tutorial Room 1

Connection instructions

  • In the coverage areas you should pick up a network named "St Edmund's Wireless".
  • To use the network you need to configure your network interface to get its IP configuration automatically by DHCP (this is normally the default setting).
  • To get from this local network to the Internet, you need to authenticate. If everything else is set up as outlined above, all you need to do is open up a web browser and connect to any web-site. This request should be intercepted and you should see a screen requesting you to authenticate to the St Edmund's Network. You do this by entering your College login and password. Once these have been accepted you will be directed back to the page you originally requested, and your computer will be able to connect using other network programs (like dedicated e-mail clients).

Things to keep in mind

  • Before you log in with the web browser, you cannot make any connections with any other programs. Only when you have logged in will e-mail clients and similar software work.
  • To keep your session 'alive' you need to accept pop-ups from the authentication server, and keep the window open, even if you are not using the web browser for other things. If you don't, you will have to re-authenticate after 10 minutes. If you are using a pop-up blocker, you need to exclude the server 131.111.223.1 from the block, or turn the blocker off while logging in.
  • The wireless side of the network is insecure. Do not use network programs which use plain-text password where secure alternatives exist (ie. use ssh instead of telnet), turn on SSL in your mail program if it supports it (Outlook, Mail and Thunderbird do), always use secure (https/SSL) versions of web sites when they are available (eg. https://webmail.hermes.cam.ac.uk).
