My MAC address is entered into the DHCP and I still can’t connect. What gives?

On June 15th, 2021, UITS implemented the 802.1x authentication protocol. This requires all computers to be registered to an individual's NETID for it to be allowed on the network. If you are receiving an IP address similar to “10.252.x.x”, you have not authenticated and must do so. Instructions for authenticating can be found here for Windows, Mac, and Linux operating systems. Please submit a ticket to should you experience any issues getting online.

Please note: this does not bypass Steward Observatory’s DHCP server. All MAC addresses must still be registered with CSG. See item below.
