  4. The device may take a moment to connect, and will show mercury as the Wi-Fi network it is using. Exit Settings.

Most devices will automatically connect to Mercury when in range once all of the steps are completed, if not simply select mercury from the wifi networks when in range on campus.

NOTE: iOS devices (iPhones and iPads) may automatically connect to other networks in range and do not have an easy way to set the preferred network from the device itself. You can:
  • Remove saved wifi networks you no longer wish to use - see full iPhone/iPad steps on the Reset Apple WiFi page, or briefly: enter Settings - WiFi - tap the network or profile name - select Remove or Forget This Network. Note that the device will store the WiFi network again if you connect to it in the future.
  • Adjust the Preferred Network list on a Mac that uses the same iCloud account to sync with the iPhone or iPad; unfortunately devices or Macs connecting to their CUMC email or other data that may contain ePHI must NOT use iCloud as we do not have the required BAA with Apple.
    See the Tip near the bottom of the Set Up a Mac for Mercury page.
Apple's KB article on How iOS decides which wireless network to auto-join has additional technical details.
