I'd strongly second that Link Aggregation should be a considered feature on the 1750... there's no hardware reason not to  . 

What do you expect from link aggregation on an EAP245?

A single 1000-BASE T interface gives you 1 Gbps full-duplex (i.e. 1 Gbps in both directions = 2 Gbps total) which covers maximum data throughput an AC1750 wireless device can achieve in half-duplex mode.

@R1D2 The AC1750 advertises 1300 mbps throughput... I want 1300 mbps.  https://www.tp-link.com/us/business-networking/ceiling-mount-access-point/eap245/

You won't get that data throughput, no change. 1,300 Mbps is wireless speed, which has an overhead of ~30% (802.11n/ac) to ~50% (802.11a), so max. data throughput is theoretically 910 Mbps in ac mode @160 MHz channel width 2x2 MIMO (MCS 7) for 1,300 Mbps wireless speed or @80 MHz channel width in 3x3 MIMO (MCS 9). Since TCP/IP communication is bidirectional, the EAP must send and receive packets alternately, not simultaneously (b/c it's a half-duplex medium).

910 to 940 Mbps is what you get at maximum on a wired 1000-BASE T interface anyway, since TCP/IP also has an overhead of ~10%, but here you get it in two directions simultaneously, thus it's actually 1,820 Mbps.

Of course, even higher wireless speeds of a device compared to its wired speed is very useful, since it reduces the amount of AirTime the device need to achieve. Remember that WiFi is a shared medium, thus there is only one sender (SISO mode) or two senders (in 2x2 MU-MIMO mode) or three senders (in 3x3 MU-MIMO mode) at any given time, which can acquire the channel for sending/receiving. Thus, higher wireless speeds help to avoid congestion of the WiFi channel.

Just for more information, I have the AC1900.. your points of interest would apply to that one, too, effectively (same advertised throughput ratings, by the way), but, TP-Link had no problem including LAG in the software on that one.  Works great..  

Yes, that's EAP330, which exceeds 1000-BASE T data speeds, so LAG makes sense for this device, agreed.
