You only need to fill in this form if you are applying to use the wired (Ethernet) connection. You do not need to use this form to use Wi-Fi.
The Wi-Fi connection is provided by Cambridge Universitiy's eduroam service. To use this you need to follow these instructions, which involves getting a token and for some users installing a small tool. Make sure you get these before you come to Cambridge if you can, as you will get online straight away.
Use the IT ticket system and select Wired Network Application from the help topics: http://itsupport.caths.cam.ac.uk/
To complete the request we will need your MAC address
MAC is short for Media Access Control.
The MAC address is the hardware address of your network card. Your computer might have it written on the back or underneath. It will consist of 12 characters, including numbers in the range 0-9 and usually some letters in the range A-F. It may have a dash or a colon between each pair of characters. An example would look like one of these:
0015E7F532DB
00-15-E7-F5-32-DB
00:15:E7:F5:32:DB
It may be called the MAC address, Ethernet ID or Physical Address. Note that we need the MAC address for the network card, not the one for the wireless connection. This has its own MAC address, so if we get sent that one by mistake the connection won't work.
1) Go to the Control Panel. To do this:
Windows 10/11: Click on the Start button, bottom left of the screen. In the search box type in 'Control Panel' and click on on the Control Panel.
2) Find your adapter. To do this:
Windows 10/11: Click on 'Network and Internet', then 'Network and Sharing Center', then 'Change Adapter Settings'
3) Find the MAC address:
Windows 10/11: Right click on the icon called 'Local Area Connection' or something similar (NOT the wireless icon, which has a different MAC address) and double click this icon. On the box that open click "Status" and look for MAC or Physical Address
Alternatively use these methods:
Click on the Start button, choose 'Run...' and type
cmd
In the window that comes up, type
getmac
and press return. The MAC address will appear, under the 'Physical Address' header.
If there is more than one you can get more details by typing
ipconfig /all
and pressing return. The correct one will be called 'Ethernet adaptor Local Area
Connection' (or something similar) and will be called the Physical Address.
If you get the message 'Media State........ Media Disconnected', try running the
above commands again with an Ethernet cable plugged in if possible.
On an Apple Mac/Macbook
From the dock choose System Preferences. Click Network and then choose Ethernet (or the adapter if you're using one - the adapter must be plugged in to your computer to show up properly). Click 'Advanced', then 'Hardware' and you'll see the MAC address.
If you run into problems feel free to contact the IT Office and we will be happy to help.
