Deco M9 plus with powerline / range extenders
I've seen a few threads on this subject but the language / jargon is beyond my knowledge so I wonder if someone can help me with an idiots guide to mixing the Deco M9 plus with powerline adaptors or powerline-based WiFi extenders.
Why do I need this? I have a workshop some 40m from my house (where the router is). Currently, to get a WiFi signal in the workshop I have 4 Deco M9 plus units talking to each other (the primary unit connected to my router and 3 further units to extend the range to the workshop - I need all those extra units because of the topology of my land). This doesn't seem very cost-effective to me!
What I would like is a mesh WiFi in my house plus a powerline-based WiFi extension into the workshop.
Is this possible and, if so, can I have an idiots guide to setting it up (ideally with a recommendation on what extra components I need)?
