IOS Device (IPhone/iPod/iPad) Owners

If you have an iOS device you may get an error saying “Unable to join the network ‘Williams Guest’”. If you get this message please try these suggestions:

  1. Try selecting the ‘Williams Guest Secure’ SSID, it will bring a login prompt asking for a username & password. Ignore that login and press ‘cancel’. After doing this if you don’t see ‘Williams Guest’ in your list of networks press ‘Settings’ in the top left and open Wi-Fi again and then change your network back to ‘Williams Guest’. For some reason this seems to fix some errors

  2. If your device is connected to another network here, or even one that has a similar name, select that network and choose ‘Forget this network’. Then repeat step 1.

  3. Try rebooting your device and reconnecting again.
