Wireless networks in Churchill

Churchill College provides a wireless network covering all of the central areas, including all of the staircases, the Sheppard Flats and all of the College hostels on Storey's Way except for the three Pepperpots (Hawthorne House, Bondi House, Broers House). This coverage is provided by the University Wireless service.

We are in the process of rolling out the wireless coverage across the remaining accommodation on the main site, the Wolfson Flats and the Pepperpots.

Wireless networks (SSIDs) provided

 

eduroam

This network is recommended for frequent use by members of Churchill College, the University of Cambridge and any other university participating in the eduroam scheme. It requires each laptop, phone or tablet to be configured to log in to the network, but this only needs to be done once for each device. Instructions for on how to configure most common operating systems and mobile devices can be found at http://www.ucs.cam.ac.uk/wireless/eduroam/localusers.

eduroam is an international project, supported in universities across the globe. This means that once you set up your computer to access the eduroam network in Cambridge, it will also be able to access the internet in participating universities elsewhere in the UK and abroad. Similarly, members of other participating universities are able to use the eduroam network here in Cambridge; they will need to seek advice from their own university for details of how to connect to eduroam. Further details can be found at https://www.eduroam.org/.

UniOfCam

This network is recommended for occasional use by members of Churchill College and the University of Cambridge. It requires that you log in using Raven each time you connect to the network; thus it is simpler to connect to than eduroam at first, but becomes less so the more often you use it. Further details can be found at http://www.ucs.cam.ac.uk/wireless/browser/howto.

CHURCHILL COLLEGE

This network is recommended for use only by those who are not able to use eduroam or UniOfCam. It is slower than either of those two networks, with more stringent restrictions on the traffic, however it is not necessary to log in to use it, and it is available to everyone.

This is the same wireless network which has been available in the central buildings for many years, so you may find that your computer connects to it automatically if it is available in your room. If so, you should either turn off your computer's wireless while in your room, configure your computer to only connect to wireless manually, or change it to connect to UniOfCam or eduroam instead.

Personal wireless routers

Before the College provided wireless network coverage in residential areas it was necessary to set up your own wireless router to be able to connect devices wirelessly in your room. In areas that are now covered by the College's wireless system, personal routers must not be used, as they can interfere with the signal from our wireless access points and cause problems for yourself or other people in nearby rooms.

In areas not yet covered by the College-provided wireless, wireless routers may be used if they are configured correctly; contact the Computing Support Office for guidance. Incorrectly configured wireless routers will frequently prevent others from accessing the network, or allow people onto the network who should not be able to do so; and thus it may be lead to your room being disconnected until the router is fixed or removed.

Comparison with wired connections

The wireless services in College run in addition to the existing wired network connections; if you are happy with your wired connection, there is no need to move over to wireless. The wired network is more suitable for intensive use than a wireless connection; this will particularly affect those who work with very large data sets, or otherwise transfer large amounts of data across the network. Any users who wish to run servers such as web or SSH servers on their computer must use a wired connection, as incoming connections are not possible when connected via wireless.
