Network name missing from available networks list

This is really weird. I have a HP All In One computer that has been connected to our home network for several years. We have six devices connected to our network.

Yesterday, one of our HPs lost Internet connection. When I tried to connect it to our Wi-Fi network the name of our network didn't appear as an option. All of other other devices list our home network as an option. 

I tried all the steps recommended for reloading the driver, updating the driver, etc. Nothing worked. 

Could this be a panoramic WiFi issue?
