Reset PRAM/ NVRAM

User's configuration data is stored in the PRAM/NVRAM when they use macOS — this includes wireless configuration information, which may cause issues when connecting to the Jayhawk network. Per Apple documentation:

NVRAM (nonvolatile random-access memory) is a small amount of memory that your Mac uses to store certain settings and access them quickly. PRAM (Parameter RAM) stores similar information, and the steps for resetting NVRAM and PRAM are the same.

If you're unable to sign into the Jayhawk network, have confirmed that your online ID and password are working for other services, and restarting the computer does not resolve the issue, KU IT recommends resetting your PRAM as the next troubleshooting step. You may need to set up other networks and system preferences as well after a PRAM reset, but your files will not be impacted by this process.

Shut down the computer. For this process, choosing "Restart" will not work.
Press the power button on your Mac to turn it on; you'll want to proceed to Step 4 immediately.
Hold down Cmd + Option + P + R on the Mac keyboard.
Wait and continue to hold down the keys while macOS boots; the computer may appear to restart. Apple recommends holding the buttons down for 20 seconds, but if your Mac plays a sound at start-up, you can release these keys after it plays the start-up sound a second time.

Once you release the keys, macOS should continue with starting up. Once you're able to log in, try connecting to the Jayhawk network again.
