Cindy is having issues with her phone. She keeps getting connections to old networks, which causes her internet access to drop out. Leo says you can forget those old network connections from time to time. Click on the "i" button to the right of the network and select the forget option. That should remove those from your "my networks" section and prevent the phone from connecting to them. Here's an Apple tech note about it. Since Cindy is dealing with a divorce, it may be a good idea just to reset the phone completely. Wipe it and start over. Or at least delete the certificates.
