We finally got our Business Fibre broadband connected. I also have a Digital Voice service, although we are still waiting for a number port to be completed. Parts of our building get virtually no signal from the Smart Hub 3. I have some Eero 7 range extenders from another set-up. Does anyone have experience of using these with the SH3? I believe that Digital Voice complicates things a bit, but I don't know the details.
