Do we have something similar to https://ispdesign.ui.com/ ?

I bought 2 CPE510 and I can't any tool to measure my distance and type of device to use.

Generally speaking, 2 CPEs are using to set point-to-point long distance topology.

There is the specific configuration step that you can refer:
1) The CPE point to point is for a long distance internet transmission, please kindly refer to this video which include the standard process:

2) Here we have the detailed setup instruction.
How to login management page of the CPE: https://www.tp-link.com/support/faq/710/
How to set up the Access Point mode: https://www.tp-link.com/support/faq/730/
How to set up the Client mode: https://www.tp-link.com/support/faq/727/

3) Please note:
a) The LAN IP address of the Access Point should be different with the LAN IP address of the Client. If the Access Point has the LAN IP 192.168.0.254, then we need to set up a different LAN IP for Client, such as 192.168.0.253
b) Do not enable the MAXtream on the Access Point if you have other devices that need to connect to the CPE Wi-Fi.
c).Change the security and set a PSK password for Access Point

4) After you set up the Access Point and Client, if you the Client has no internet, please follow this link to do the troubleshooting.
