If I use the wifi I get a download speed above the 80Mb/s as I'm standing next to the repeater. When I switch to the wifi of the repeater I only get 10Mb/s. How is it possible that I lose almost 70Mb/s just by switching?
I'm not sure what could be causing the bad down link, however I have a few questions which should help find the issue.
On your EX2700 is both of the LED's (Router Link & Device Link) Solid Green?
Within the admin page, have you set a channel or is it on auto? As if you have set a channel, it could cause interference with another channels used by a different AP.
