Network Scan Says Router HNS-WEAK-PASS but...

[Sea Monster]

I'm getting the HNS-WEAK-PASS , which is non-specific with one vague error code.  No other info provided by Avast, ok IP address but I know my router's IP. :-)

My Wi-Fi SSID's are changed and PW's are lonnnng.  Guest Wi-Fi is disabled.  Router PW is also long and unique. UPnP is off, Ping is off.  So...

What else could Avast be probing/seeing?  What am I missing, some ISP backdoor wide open?

Thanks for any enlightment!

...I'm using the free version.  If I upgrade to paid, do I get any better feedback from the application? Better documentation?  Support from Avast?

I would stick with free version, not worth the upgrade.
