@Alexandre. I don't have any preference as to equipment (& frankly know nothing about it) but there seems to be no need for the mesh as my home is not big. I started with that from Costco's website...

@Alexandre. Thanks, but I don't have access to the router so Ethernet connection is out of the question. Is there anything else which I can use wirelessly?

I'm using the signal from the community's internet. How can I use the TP-Link Deco M9 Plus Tri-Band Wi-Fi System to extend the signal as I don't have access to that router? Thanks
