Instructions on how to set up your computer
- Remember that you must not connect your computer to the College network until you have registered for (and received) an IP address from the Computer Support Office.
- Check to make sure that you have entered all the network information correctly, according to the instructions. If you are having trouble accessing the Internet or e-mail, pay particular attention to the TCP/IP section of the instructions.
- If you can't access the Internet, the problem may be in the way that your web browser (Firefox, Internet Explorer, Chrome etc) is set up, or in the way that you have configured your TCP/IP. First, make sure that the problem is not just with the website you're trying to look at - try several different ones such as www.chu.cam.ac.uk, www.cam.ac.uk or www.google.co.uk. Try going to a command prompt (known as 'Command Prompt', 'bash' and 'shell' in various different operating systems) and typing: ping www.cam.ac.uk
- If this produces a stream of similar-looking success messages, then your TCP/IP configuration is correct, but your web browser may have incorrect proxy settings, or a non-existent home page set.
- If it produces a failure message similar to 'DNS error' or 'Bad IP address' or 'Unable to resolve name' then you should check the entries for 'DNS Server' in your TCP/IP configuration. If it produces a failure message similar to 'Destination host unreachable' then you should check the entries for 'Host name', 'Domain' and 'Default gateway' in your TCP/IP configuration. If you can access external sites such as Google but not sites within Cambridge, then check your 'Subnet Mask' setting.
- If it produces any other failure message then the problem is most likely to be in the network adapter.
- If it produces no response at all (or on Windows systems a series of messages saying 'Request timed out'), you should check that your network cable is plugged in securely at both ends, and if so you should ask the Computer Support Office to check your network socket and cable for you.
- If none of the network features are working, make sure that your network interface card (or NIC) is able to 'see' the network. On desktop or tower case machines, there is usually at least one light on the NIC's metal plate (on the back of the computer beside where you have plugged the network cable in). On a laptop machine, there is usually at least one light either on the edge of the NIC, or on the adapter (which has one end plugged in to the NIC on the computer, and the other end plugged in to the wall socket). One of the lights on the card should probably be flashing irregularly. If not, the card may not be correctly installed, so try uninstalling and removing it, and then re-installing it, possibly in a different slot. (Note that the design of different NICs varies, so a minority of them may not have a flashing light as described above.)
If none of the above suggestions solve the problem, please contact the Computer Support Office for assistance. We should be able to arrange for someone to have a look at the problem for you.
Please do NOT bring your computer itself to the Computer Support Office for diagnosis without first contacting us and making an appointment.
