"SSID" may be risky

I get a notification from Avast Mobile Security that I cannot clear. It says “(my wifi ssid) May be risky.” When I open it, the info says my router has the default password and username, however it doesn’t. The username is a combo of my family’s surnames, and the password is a random 14 character string with 2 capital letters, 5 lowercase letters 6 numbers and 1 special character. No repeating characters and no actual words in the password. I made it with a cipher so there are no actual words or repeating characters in the password. I would like to stop receiving this notice that blocks a third of my lockscreen and cannot be cleared.

I’ve tried running a scan, turning off notifications, resetting my router, disabling wifi for about an hour and trying it all again. As soon as it connects to wifi the warning pops up.

Disable pnp’, change your WiFi password etc.

Please the threads about this.
It has been explained several times before.

Thanks for the slightly vague generic reply. I have done all of that, and read the other posts. Nothing changes the pop-up. I’ve even turned the wifi off and it still pops up when there is no network by that ssid in the area. It’s like it’s cached somewhere and clearing caches only gets rid of it for a few minutes. Some posts said to disable wifi scanning but I can’t find a way to do that.

Hi, have you read through this one?

Thank you for that link.

There is no “potential wifi issues” in the wifi notifications, but there was a switch for “security scan” it says “occasional suggestion to scan your network for security threats” I turned that off and it got rid of the pop-up. It’s been gone for about 20 minutes now so we’ll see if that worked.
