Weak WiFi password detected

Does anyone have any ideas about this. I acquired a new router which allows me to use special characters in my wifi password it’s now has 4 uppercase characters, 4 lowercase, 6 digits and 2 special characters. Despite this Norton still insists that my password is weak and it occassionaly decides that my home network is so risky that it needs to turn my VPN on for me. The trouble being that some of the systems that I use in my work for a major UK charity do not like the Norton VPN.

I did spent a fair amount of time chatting to a Norton Support person about what constituted a secure password and they couldn’t give me a definitive answer.

I’m running version 25.3.9983 (build 25.3.9983.923) and I get the following message

My home wifi network is defined as Private.

Does anyone else have this problem and have they manage to fix it? I also have the delightful Windows Network UDP17 message feature cluttering up my machine. I hope these are fixed sooner rather than later as I’ve got lots of better things to be doing instead of spending time on what Norton has done this time to slow my machine down.
