Bumped this to ask a question. I am still with Talk Talk and got a free upgrade to their Full Fibre 900 package. I have the EERO Pro 6 mesh set up but am getting no noticeable increase in measured speed at the firecube or firestick.
Contcted Talk Talk who advised me the EERO is receiving 980mbs down and 109mb up. They suggested relocating the main EERO to a more suitable position in the room.
Bought a longer Ethernet cable to allow me to try it in several different positions and heights but still not getting any changes.
Is it a limitation of the EERO and if so, would getting a commercial OTS Router be a better way forward?
