There are many similar threads talking about unstable connection. We have installed CPE510 at many locations. But last week we faced this issue. Despite all the troubleshooting still it didn't work. We knew it was a small problem that we are missing out. Since there was a mobile tower close the client device, we had a doubt the signal from the high power antennas may be causing an interference, which is very unlikely but as the problem was not getting resolved we were looking at every single parameters. Three days past, called the support and they too asked to repeat the same steps. Only change they asked was to change the region to test mode. So, first try to ping directly between device before up linking the internet. Adjust the power to 10, and change to lower band with 50mbps speed and 20hz. Change each parameter on AP and observe the number of pings. You can create a script in powershell to ping the IP continuously for 5 minutes with log of successful counts and failure. Also have a sound when the ping fails. That way you can know if the ping fails when you are on device setting page. When the number of pings improves. Lock the client with AP with the best signal. Now to fix the drops, ensure to enable IGMP proxy. When you connect the uplink, enable it on router too. Selecting the DFS channels may also works but like we had an issue where locally it works but when connected to WAN if it drops, try this. For us it worked perfectly after struggling for three days.
