My ISP contract is for 200mb and if Ive checked with their router and I get the speed. But once Ive installed the DECO E4, I only get up to 70mb, Ive tried only allowing the 5ghz network and the speed doesnt change, Ive been measuring less than 1ft away from the main DECO and still my speed doesnt go up. Ive tried swapping the DECO and still get the same speed. Ive tried a hard reset and still get the same results.

But Ive got steady 70mb around every inch of my house.
