Hi there. I wish I had some of the issues many here have!  I am in a rural location connected to a turbo hub so accessing the internet via the LTE network. My turbo hub has built in wifi capability but I have kept it turned off. My deco hardware says I am getting about 11 Mbps download and 5 upload which is actually usable for me. However, when I do a speedtest from my Phone X, I only get 1.3 down and 0.15 up!  I tried turning on wifi on  my turbo hub and get close to the speeds my deco router tells me from its built in speed test. I get around 9 down and 4 up if I test my iPhone directly on the LTE network. I have rebooted everything several times and have tried connecting to different ports on my turbo hub to connect my Deco. No luck. I have two decos to create a home network and they are different floors of a two story home separated by about 50' and one floor. Really need to make this work as I rely on this mesh network to work from home!
