I 'm serving Internet access to many users. Often I have 30 to 50 clients on the same access point. It looks like the airtime is my bottle neck. By cable connection, I see the full connection speed of 50 Mbps. By Wi-Fi with a single client connected, I can download with about 25 Mbps. But together with all clients, I see speeds of below 1 Mbps and the cable uplink is occupied with about 5 Mbps only. I assume that some few clients with very slow modulation rates are occupying the airtime and thus clients with faster connections are throttled down unequally much.
I know that putting more access points on different non overlapping channels will help. But on top of that, I like to have the airtime fairness feature on the access point. Is the latest LEDE Version supporting this well enough to use it? Which hardware would you suggest for this (Outdoor use preferred)?
