If you are experiencing problems with your network connection, you should take the following steps to attempt to resolve your problem. 

Check your network cable

To use the Halls Network you will need a standard Ethernet cable. This cable is a ‘RJ45 Cat5 Ethernet Cable’. The plugs are is 10 x 20 x 6mm and has eight metallic contacts (see photo) and can be any length. You must make sure you NOT using a crossover cable or a modem cable – if the cable does not have 8 metallic contacts or the ends are different (including the colour order inside the plug) then you have the wrong cable.

Ethernet cables are available from the union shop or PC World on Tottenham Court Road (http://www.pcworld.co.uk/gbuk/belkin-ethernet-cable-2m-00772729-pdt.html)

MAC address violation

Your port may have been shut down due to a security violation. When you activate your connection your user ID and unique physical address of your PC are registered to the network port you are connected to. If you attempt to connect your PC to another port or another PC or network device is connected to your port, a security violation occurs; this is because the user agreement states that only one device can be registered per port. A violation results in a port shutdown. After 10 - 15 minutes the port will re-activate back into the registration stage where you will have to enter your details again to restore your connection.

Supported Operating Systems

Fully Supported and recommended:

Windows XP/Vista/7
Mac OS X 10.4, 10.5, 10.6

Very limited support:

Linux
Windows 9x/Me
Mac OS X 10.3 and lower
Game Consoles

Have you changed your hardware?

If you have changed your machine and/or Ethernet card you must re-register the connection as it will not work. This is because every computer connected to the network has a unique number associated with the network interface card called the MacAddress which you bind to the data socket when you register your connection. Please follow the steps on the changing your connection details page.
