Getting the WiFi to be rock solid in our period farmhouse, with thick brick, insulated walls has been a challenge. We installed TP-Link’s M9 Plus mesh network system which is very robust and very reliable, but it struggled to connect the network in the main portion of the house to the northern end.
We tried to bypass the brick walls in the hallway using TP-Link’s AV600 Powerline, and it did work, but I suspect that the previous owners electrical wiring was less than perfect and we would regularly drop connection which wasn’t ideal.
So the latest workaround was to add two TP-Link Deco M5 units in strategic places to get the signal through, and it’s worked like a charm. Not only has it made the mesh network more reliable for surfing and streaming, it’s also given our Netatmo security cameras a better connection to locally save recorded video footage.
