What if I cannot log on to eduroam?

If you cannot log on to eduroam, then as a temporary solution note that faculty, staff, and students can use the guest wireless network WITHOUT setting up a guest wireless account.

Then just use your campus login ID and Kerberos passphrase as the credentials. To be clear, UCD computing account holders do not need to set up guest wireless accounts to use the guest wireless network (they just use their existing campus computing account credentials).
