Hi,

I am getting an warning from iMac and iPhones " weak security " connection message. 

When I read Mac Support , I thought it was related old modem and WPA connections. 

I changed modem with a new one WIFI 6 model and wifi network using AES and WPA2/WPA3 more high security in modem wifi network. No problem.

But when we connected again my RE450 model range extender.. All devices warning again same "weak security connection " message , if I use extender network.

Could you someone inform me that , How can I a secure connection via range extender device ?

Thanks in advance

Regards
