The University offers two wireless options to the community while on campus: Eduroam and the uchicago-guest wireless network. Details on how to connect your device to those wireless networks are presented in this knowledge article Wireless Network Access at the University of Chicago. Select a question below to find more.
If you're unable to connect to Eduroam, there are a few steps you can try on your own to diagnose and fix the issue. View Wi-Fi troubleshooting tips for Mac or Windows 10. Contact IT Services if you still can't connect to the network. In addition, although our Wi-Fi networks are quite robust, wireless availability can occasionally be intermittent in some locations on campus. Please report these types of issues by completing the Provide Wireless Network Feedback form.
The Eduroam network is secure because your data is encrypted between your device (computer, smartphone, iPad, etc.) and the wireless access point. The encryption keeps hackers from reading your data. For example, they can't see where you are visiting on the internet or capture your banking information while banking online.
Some operating systems and devices do not immediately refresh the connection, meaning there can be a delay of approximately 10–15 seconds for the connection to resume after the device has fully awakened. In some cases, you can speed this along by simply toggling your wireless connection off and then on again. Certain versions of macOS seem to exhibit this behavior more often than others.
On the eduroam wireless network, your computer or device is assigned a private IP address in the form 10.x.x.x for the purposes of on-campus connectivity. When you connect to off-campus sites, your private 10.x.x.x address is translated to a shared 128.135.x.x address, which permits communication outward to the Internet at large.
If you find you cannot access an on-campus service or resource while connected to Eduroam, either the address translation is not occurring, or a local firewall is blocking the connection. Contact the owner of the service or resource in question to address this oversight.
No. Off-campus devices will not be able to initiate connections to a private University 10.x.x.x IP address.
If your device is lost or stolen, your device will continue to present your CNetID and password information, even if someone else is using the device. If a logged-in device is lost or stolen, the best practice is to change your CNetID password at MyAccount. Devices will not immediately be removed from the network, but they will remain connected until the next time the client authenticates. If there is a need to immediately remove a particular device from the network after changing the password, contact IT Security at 773.702.2378 (2-CERT) or security@uchicago.edu.
As specified in the UChicago IP Address Allocation article, any 10.x.x.x address should be recognized as belonging to the University, just like any 128.135.x.x address. The University has used 10.135.x.x addresses for several years, but the wireless initiative will include the 10.150.x.x and 10.151.x.x ranges as well. If you are responsible for University resources with access restricted by IP address, please verify that the appropriate IP ranges are allowed. Some common activities that are restricted by IP include remote desktop, file sharing, and secured websites.
