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

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?

Hi NancyFusi,

Please contact the WiFi system manufacturer for help.

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 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.
