Thanks for the prompt response. the connection speed has been fluctuating all day so perhaps I need to give it a window to settle down. Although found earlier if I disconnected the M5s that I could hit 270mbps but when connected getting about 30-50mbps. However I am also seeing with the M5s disconnected the speed dropping to 70mbps - so clearly something is amiss. Ticket opened with ISP to monitor but wanted to ensure the M5 would support up to the 350mbps

If you are running your Deco mesh in Router mode, you may wish to check if you need to increase value of QoS parameter to match new Internet speed. There are multiple duscussions on this forum on that topic, also FAQ article 1601 reviewing QoS feature may be of help.
