@Sunshine I see what you mean.

They are paired via OneMesh. I could change the Auth method to check but I'm surprised there is no error message before that if the Paired device doesn't support that authentitation method. That would mean there is a really poor design; or they need to update the FW from the TL-WPA7517 to include that authentication method. There isn't even a beta FW at least to resolve that problem.

If I change the Auth method that means I'll have to log in again in the 20 devices I have at home. What I want is a viable response from someone working in TPLink stating this either works or not. I changed to a more secure authentication method as it's suggested to do so nowadays being there multiple ways to crack WPA2/etc

To take the point across: I could take the authentication off as well; but that won't cut it for me.

Thanks anyway for your kind response :)
