Seems there is a fix for a wifi security bug for iphones. The issue is that when on wifi someone could take over your phone. If you haven't received the update, check for it.

This is what happened to my husband's company phone (iPhone 6s) on Friday. He was working from home and connected to our home network which is behind a firewall. He was not using the phone. When he looked at it, almost all the apps had disappeared except for the default apps you can't delete and a few company installed apps.

Later that evening, we went to stream something on the Tivo and were presented with a screen that we were not connected to the internet. Every other device in the home worked fine. We had streamed on the Tivo on Thurs. night without issue.

We restarted the Tivo and it connected just fine.

Nothing appears to be out of order.

Could this iOS bug have allowed someone to access his phone and somehow also hit our Tivo? The router & extender are less than a year old with a pretty strong password.
