@lukass2000 I don't know, but I suspect that 4 antennas spread the signal better than with two antennas. There is also more powerful hardware that also helps, EAP660HD should in theory handle over...

@lukass2000 I have EAP660hd and EAP653. both are connected with 1gb lan, EAP653 has 160Mhz bandwidth which can increase the speed at short distances. I do not recommend 160Mhz unless you live far up...

@joemanderson01 I have tested such a module before, I only have 1gb but it connected to the router with 10gb and linked to the ISP with 1gb, now I have replaced it with DAC so I can't test it now....

@Joe689 if you use cloud essential it is a very limited version, it only has wireguard as far as i know. you can install controller on a windows pc or a linux pc and you get all the features.

@SlowPL It is the hub device that determines how many spokes you can have, if you have an ER8411 as a Hub you can have 32 spokes.
