I have a Netgear Nighthawk ac1750 over there plugged into the POE adapter and over wireless I cant get above 40 download.

If set up correctly, CPE510 links can achieve 80 to 90 Mbps full-duplex – that means 160 to 180 Mbps data throughput on the half-duplex WiFi side – over a distance of 560 (and probably more) meters. See https://community.tp-link.com/en/business/stories/detail/1.

Recommendation: turn off MAXtream TDMA, it has not much advantage if using just 2 CPEs. Set WiFi mode to 802.11n-only , 20/40 MHz channel bandwidth (default), WMM/QoS enabled (default), distance to Auto (or the actual distance) and align the antennas properly. Last point is most critical. Make also sure the devices are grounded according to the installation guide.

Also keep in mind that using WiFi at the remote side can slow down things, especially if using the 2.4 GHz frequency band. But this is another problem not caused by the CPE510.
