Android Avast Mobile Security WI-FI CHECK false warning

When scan my network using the Android app Avast Mobile Security (WI-FI CHECK) I get a " is dangerous.

“Show issues” for the NETGEAR WI-FI router tell: Router has a week password.

My admin password is more then 8 random letter and numbers, eg
hlkjh7gulkJS

When perform a scan on Avast for PC I get: All is OK.

When I follow the guide for fix the problem in Android app Avast Mobile Security and change the password to more then 8 random letter and numbers in the NETGEAR router and then perform WI-FI CHECK in Android app Avast Mobile Security all is OK.

After 4 times of WI-FI CHECK the WI-FI network is dangerous again. In PC the network is not dangerous.

Use the same algorithm so the numbers of bug can be reduced.
