WiFi Access in the UC Berkeley Libraries

There are a number of ways to access WiFi networks while using the University of California, Berkeley Libraries. Depending on the user's status, these services can wirelessly connect users to licensed library resources as well as the full range of publicly available internet resources.

Overview of WiFi Options Available at the Library

Patrons using the UC Berkeley Libraries, depending on their status, have a variety of options for accessing Campus WiFi networks. Below is a brief listing:

  • UCB students, faculty and staff use Airbears2. A CalNet ID and Airbears2 key are required to set up a connection. Access to licensed library resources is available via AirBears2.
  • Visiting scholars who are registered with the Visiting Scholars and Postdoc Affairs (VSPA) Program obtain a CalNet ID from a sponsoring department to access Airbears2. Access to licensed library resources is available via Airbears2.
  • Students, researchers and staff from other educational institutions use eduroam WiFi which allows researchers from participating institutions campus Internet connectivity. Access to licensed library resources is available via eduroam.
  • General Public including Cal Alumni use CalVisitor WiFi which is available for visitors to campus. No password required. Access to licensed library resources is not available via CalVisitor.

Moving to AirBears2

Airbears2 provides authentication and confidentiality for data being transmitted wirelessly. The secure automatic connection means that users only login once. The encryption of wireless data traffic improves security.

Airbears2 requires several steps to configure before it can be used.  These steps include creating an Airbears2 key and configuring your computer or device to use Airbears2.

1. Creating a key - Use your CalNet Passphrase to log in to the WiFi Keys website and follow the instructions provided. See additional information on managing your wireless key.

2. Configuring your device or computer -  Once you have created your Airbears2 key, it is necessary to configure your device or computer to use Airbears2. To do this select Airbears2 as your WiFi network, accept the certificate that is offered (this secures the association process), and log in with your CalNet ID using your Airbears2 key as the password. Once you have done this the first time, your device should automatically use Airbears2 whenever you are within an area that it is provided (inside almost all campus buildings). For step-by-step information on how to configure your device for Airbears2 go to How do I Create a WiFi Account for airbears2?.

2. Configure your device or computer - Connect to the eduroam SSID, and provide your CalNet ID as the user name, for example if your CalNet ID is oski, you would enter "" Enter your AirBears2 WiFi Key as the password. Once you have done this, your device should automatically use eduroam whenever you are at an institution that provides it. Visit for more information about this service.

Support for CalVisitor

UC Berkeley provides CalVisitor as a convenience to visitors. No support is offered for devices or users with difficulty accessing the service. Any malicious activities on the network will result in the offending device being permanently banned from the network. Compromised devices (infected with viruses or other malware) will also be permanently banned. Bans are automatically implemented and can not be revoked.

Because CalVisitor is a public network it should not be used for any type of sensitive data. SSL, VPNs and other encryption technologies may be used by client devices to improve confidentiality of data sent via this network.

Issues relating to Switching between AirBear2 and CalVisitor

There is a known issue with Apple devices (iOS, Mac OS) if they try to switch services (i.e., SSIDs) on the University's wireless network. The network remembers you and the service you were on.  For example, if you were on Airbears2 and try to shift to CalVisitor, you may receive an "Unable to Join" message. The workaround is to turn off your device's WiFi service, wait for 10-20 seconds, and then turn it back on and reselect your network preference. For iOS devices, you may also try to disconnect from your current WiFi network by using your device's "Forget this Network" feature (Settings -> Wi-Fi -> name of the wireless network -> Information icon -> Forget this Network).
