MITnet: Wireless (WiFi) Network Infrastructure Upgrade
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Mar 23, 11:00 EDT
Scheduled - IS&T will be upgrading portions of the wireless network infrastructure. Wireless access points throughout campus are expected to incur a brief reboot resulting in a temporary (10-15 minute) loss of wireless connectivity for individual buildings during that time. The wireless network as a whole is expected to remain available to users. This maintenance will affect the following SSID ("MIT SECURE", "MIT", "MIT GUEST")

As part of the MITnet Next Generation Project, the following wireless network IP address ranges will also be changed.

MIT SECURE
Current IP Range = 18.40.0.0/16
New IP Range = 18.20.0.0/16

MIT
Current IP Range = 18.30.0.0/16
New IP Range = 18.21.0.0/16
