When experiencing Wi-Fi issues while connected to cusecure or CUPUBLIC, try "forgetting" the wifi connections. 

To do this: 

Open "System Preferences" (gear icon) > Click "Network" > then select cusecure or CUPUBLIC from the list and click the minus “-” icon just below the Wi-Fi list to forget & remove it.

Click on the Wi-Fi icon near the clock at the top of the screen > select cusecure or CUPUBLIC to reconnect.
