Currently paying for Infinity 2 but struggling to get above 50Mbps on anything, Replaced the HH5 with a Arver VR900 last week as it kept dropping the wireless on us.
think anything can be done to increase the speed or it might just be worth dropping down to inifnity 1 ?

if your noise margin drops to nearer normal 6db then your conenction speed will increase nearer your attainable speed. this should happen automatically but will take a few weeks of 24/7 stable conenction
