Wi-Fi Issues Fall 2021

Eduroam is the primary secure network available throughout campus, in campus residence halls and at University Village. Students must connect to eduroam in order to have a secure connection to the campus network which allows the use of campus resources (e.g. digital library resources). To get started:

  1. Connect to a Wi-Fi source other than eduroam. Step #2 below is easier to complete from a laptop or tablet, rather than your phone.
  2. Use your CalNet ID to log onto the Wi-Fi key website
  3. For those new to campus:
    1. Select "Create New Guest Account."
    2. Enter your User ID into the "Your User ID" field. It must match the ID listed above it.
    3. Leave "Account Activation" option set to "Now," then click "Create."
    4. The next screen will show you an automatically-generated password (aka key). Copy this key and use it as your password when logging into eduroam.
  4. For those returning to campus:
    1. Click on your actual username (not the word "username").
    2. Select "Print" from the new row that appears, which creates an automatically-generated password (aka key). Copy this key and use it as your password when logging into eduroam.
  5. In your Wi-Fi network options, choose "eduroam." Your eduroam ID is your CalNet ID followed by; for example, if your CalNet ID is oski, you should enter "". Your password is the Wi-Fi key you create in the previous step.
  6. Use this username and key to access eduroam on each of your devices while on campus.
  7. For assistance, contact the Student Helpdesk.

In addition, eduroam(link is external) provides network access at over 2,400 participating institutions in the US and thousands more world-wide. When visiting a participating institution, UC Berkeley students who have configured their device to use eduroam can automatically connect to that institution's network.


CalVisitor provides basic network access for visitors to campus who do not have a CalNet ID; it is not recommended for Cal students to rely upon for Wi-Fi. CalVisitor is less secure than eduroam and does not encrypt wireless traffic. Some campus resources may not be accessible while connected with CalVisitor.
