Galaxy S9= keep getting message "WiFI Disconnected" while at home

[Android Central Question]

Kept getting message on my Galaxy S7 Edge "WiFi Disconnected" at random times while at home connected to my wireless router provided by cable company. Just upgraded to Galaxy s9+ just today, and I still get this message at random times. Wifes Note 8 never gets this message. So now that I have this issue on 2 different devices but not my wifes devices what the heck is up?

Welcome to Android Central! Try rebooting the router by unplugging its power for about 30 seconds. If that doesn't work, see this guide for more ideas: http://forums.androidcentral.com/am...roubleshooting-wi-fi-connection-problems.html

Do you have any VPN software installed (Cisco VPN is what caused it for me)? This bugged me for years on my S5, until I got so sick of it that I systematically removed apps until the problem ended.
