About Eduroam

If you look at the wireless networks available to you on campus, depending on where you are you may see one called “eduroam”. Eduroam gives you access to the Hampshire network just as if you chose Wallace or Gromit. But the really cool part about Eduroam is that if you travel to many other campuses–including all of the five colleges–you will see Eduroam as an option there; if you connect via Eduroam at Hampshire first, then you will be able to connect to Eduroam at any other campus that supports it.

Connecting to Eduroam for the First Time

The first time you connect to Eduroam you must be on the Hampshire College campus network. You can find full instructions at, but a few salient points:

  • Eduroam does not work on Macintosh computers that are running system 10.6 or earlier.
  • Connecting to Eduroam on Windows 7 takes a little more work than on other systems.
  • When you get to the point of entering your username and password to use Eduroam, you must enter your username and include “”.

Eduroam and Certificates

When you read about setting up Eduroam you will come across the word “certificate.” Certificates are special electronic documents that guarantee your computer is connecting to the service that is who and what it claims to be, and also encrypt your data in transit. Before your computer connects to Eduroam it will first want to check that Hampshire’s Eduroam certificate is valid; this includes that it was generated by a trusted authority, and that the certificate has not expired.

Hampshire’s Eduroam Certificate

Hampshire’s Eduroam certificate is expiring soon, but we have generated a new one that will be valid for 5 years. This certificate will be installed on your computer when you first connect to Eduroam at Hampshire.

If you have previously used Hampshire’s Eduroam service, your computer installed a version of the certificate that is expiring shortly, and you will need to update the certificate on your computer. In many cases this will be simple–the next time you connect to Eduroam you could receive a message telling you that there is a new certificate, and all you have to do is make sure it has the correct serial number and accept it.

On Windows 7 this process is more complicated. You should run the Eduroam setup program at In most cases this will work smoothly, but if you find that your computer will not connect to Eduroam after doing this, please contact the IT Help Desk at 413.559.5418 or
