tried to connect Range wi-fi extender to my mac desktop, its not letting to connect why?

Any Anti-Virus software should be deleted from your Mac due to the issues it produces.

But I agree. If you need a stronger Wi-Fi system, a mesh configuration would be a good choice. I personally use the Linksys Velop (3-pack), but you can see what else Apple sells from 3rd parties here: Mesh Wi-Fi Networking - All Accessories - Apple.

I have a Prescitech extender and had to have it temporarily plugged right next to my iMac and router in order to get it linked to my LAN. Once it was setup I could take it to any power outlet in the house, plug in and extend from there.

What does your manual say about setting up? What make and model is it?

I avoid range extenders, due to their unreliability and only a 1/2 duplex connection. If your network is not strong enough to support ALL of your devices in your home then you may be a good candidate for a Mesh network.

Hi NancyFusi,

Please contact the WiFi system manufacturer for help.

Cheers,

Jack
