When testing the download speed directly from the modem, it is what I expect 300 mbps

in order to distribute the access i use the A7 and via the Ethernetport on this device I only get 90 mbps

through the wireless network I only get 40 mbps

are there any settings I have missed, or does the A7 "steal" this much speed/capacity?

If so, are there other products out there that steals less?
