Thanks Dean.You have only one rule for firewall filter . Make a new one to separate 192.168.99.10/24 not 192.168.90.0/24 as you do now.. Look that ip adress on ether1-gateway is 192.168.99.0. Also when set dhcp client set the lease time to be 00:10:00 not 3d 00:00:00
It is mistake. hAP lite (both versions) have LEVEL4
But the problem is that there is no LOS at Point B.I would do 2 ptp links with SXT. You can do Omnitik with sxt but ptmp gives additional latency.
SXT is cheap.
