I am using a Archer C7 v4. However there is no dropdown for my model, so A7 is used. The firmware is correct. I am unable to toggle the DoS switch. The other DoS settings can be switched though. Also, i have manually set it for wpa2/personal with WPA2-PSK and AES. My Leviton smart switches show the network is unsecured, Is there a way to verify the security is functioning properly?
