Wireless Troubleshooting

Check the spelling of the network name. CaltechAirpass is not offered on 2.4 GHz, so some older phones will not see it. Use Caltech Visitor instead.

For Caltech Secure and eduroam, test your access.caltech username and password by signing in at access.caltech.edu. If that fails, your username or password is wrong, and you can reset it there. On eduroam, enter your username followed by @caltech.edu. For Caltech-IoT, check the password's expiration date, then open a ticket if it has passed. For Caltech Visitor, your account lasts 24 hours, so register again.

On Caltech Secure and eduroam, check that the server name is cp1.caltech.edu, then accept. If the name is different, do not continue and contact the Help Desk. You may see this prompt again from time to time.

Open a web browser and go to caltech.edu. If it still doesn't appear, forget the network and join again.

Test the same site on another network, because the problem may be at the destination. Custom DNS servers and some VPN types do not work on Caltech Visitor and CaltechAirpass. See the "What works" table on each page. Try turning off any custom DNS or private DNS setting on your device.

Move closer to an access point. CaltechAirpass is rate-limited, so is slower than Caltech Secure by design. Note whether the problem happens in one place or while you move between buildings, and put that in your ticket.

If you don't know who runs it, open a ticket and ask us for the administrator's contact information.

If a device that worked normally stops working everywhere on Caltech wireless, it may have been blocked for security reasons. Open a ticket and say so.

Connect it to Caltech-IoT.
