WiFi Security compromised

For the past few weeks Norton Mobile has given me a wi-fi security compromised network error message which I know is wrong.  I've also gotten the KRACK error message, but it doesn't tell me what to do.  I uninstalled and then reinstalled Norton Mobile, but it didn't solve the problem.  Both Verizon security as well as another app I tried is telling me my wi-fi is fine. Is this a false error from Norton?  What else can I do to resolve this?

For the wifi security compromised message, what does it tell you when you tap for more information? Do you happen to be using wifi extenders in your network? Here is another thread with users reporting the same kind of message.   https://community.norton.com/en/forums/network-compromised-0

For the Krack message, when you tap on Fix Now, it instructs you that you need a firmware update from your device's manufacturer. The Krack vulnerability affects almost every wifi enabled device in the world. Here is some information on this vulnerability.   https://www.krackattacks.com/
