Networking, Wireless, Forgetting a Network

How to remove a wireless network that is currently configured on your device.


Most devices "remember" wireless networks they have previously joined, and will automatically connect to the first one they see.

If your device is configured for IllinoisNet, but also still remembers other University wireless networks (such as IllinoisNet_Guest), it may automatically connect to the wrong one and negatively impact your experience.  To remedy this, tell your device to "forget" unwanted networks using the instructions on this page.


To forget an unwanted wireless network (e.g. IllinoisNet_Guest) on an Android device:

  1. Open Settings and select Wi-Fi.  This displays a list of all available wireless networks.

  2. Long-press the unwanted network, and choose "Forget network".

  3. Verify that the forgotten network no longer displays "Connected" or "Saved".

  4. Optional: while you're here, you may wish to also consider
    • un-checking "Remember networks this computer has joined".
      This makes it more difficult to accidentally put IllinoisNet_Guest back on the list, but it also means you'll need to come back to this screen and manually click the plus sign when you want to add a new preferred network (such as a home wireless network).
    • selecting the 802.1X tab to see if any profiles are currently installed.
      If so, and if you need to remove one, see the additional instructions further down (note that this is not necessary just to forget IllinoisNet_Guest)

  5. Click OK.
  6. Click Apply.

  7. At this point your device might still be connected to the unwanted network.  If so, Turn Wi-Fi Off and then Turn Wi-Fi On again, and it should automatically reconnect to a Preferred Network (e.g. IllinoisNet) if available.

If you also need to delete a previously installed profile (i.e. because something went wrong and you want to start over from the very beginning of the setup process):

  1. Open System Preferences and select Profiles (note: Profiles may not appear if you don't have any profiles installed).

  2. Select the unwanted profile, and click the minus sign.

  3. Click Remove.
