Beavernet Wireless Network

The original Caltech wireless network (Beavernet, Guest, and Registered) was first implemented more than a decade ago and is still in use today while we transition to newer wireless networks (Caltech Secure and Caltech Visitor).

For details on the wireless refresh project, including a rollout schedule, please click here. Buildings that have been converted to the new wireless network are noted on the rollout schedule, as well as through building signage. 

Beavernet Features

  • Encrypted network
  • Available only to Caltech faculty, staff, and students
  • Up to 18 times faster than Caltech Guest wireless
  • Connect to Beavernet by entering your access.caltech credentials


Anyone with access.Caltech credentials can connect to Beavernet. This includes Caltech faculty, post-docs, graduate and undergraduate students, staff, retirees, and visitors who have completed paperwork with Human Resources. 

How to Connect

For information on configuring your wireless device to connect to Beavernet, see the links under “Beavernet Wireless Documentation” in the right-hand menu on this page.

The Caltech wireless networks deployed by IMSS support many advanced features, including secured authentication and advanced encryption of wireless traffic. The wireless connection protocol supported is IEEE 802.11b/g. In addition, campus guests will be able to connect without prior registration, which can enhance conference attendance on campus.

Which network is right for me?

In order to take full advantage of the original wireless networks, users are urged to update the device driver for their wireless network card, as well as the underlying operating system (e.g., Windows, Mac OS X, Linux, etc...). Please see the following page for a list of required and recommended hardware and software to connect to the new Caltech wireless networks, in particular for the encrypted wireless network "Caltech BeaverNet".

The original wireless network allows a user to connect to any one of the three new wireless networks (SSID) at any single time. The following table summarizes the features associated with each SSID.

SSID Authentication
Wireless Traffic
Wireless Speed
(per user)
Network Protocol
Caltech Guest No No Up to 11 Mb/s Only HTTP, HTTPS, SSH and VPN* are currently allowed
Caltech Registered MAC address registration No Up to 21 Mb/s No IP protocol restriction
Caltech BeaverNet IMSS (access.caltech) account Yes, using AES Up to 40 Mb/s No IP protocol restriction

*In order to create a VPN tunnel over the wireless network, the VPN client must be set to use IPSec over UDP or TCP, NAT-T, OpenVPN, PPTP or L2TP. Native IPSec VPN tunnels are not supported.

In buildings with the original wireless network, IMSS recommends connecting to Caltech BeaverNet over Guest and Registered.

  • If you have a relatively current computer that supports or can be upgraded (as described above) to support 802.1X WPA2 Enterprise authentication, selecting Caltech BeaverNet will provide the best features, performance, and security.
  • If you have an older computer or iPhone that does not support 802.1X WPA2 Enterprise authentication, select Caltech Registered. Be sure to register your MAC address with us.
  • If you have a device that does not support authentication or does not have a user interface to enter authentication credentials, select Caltech Registered.
