A TP-LINK CPE210 was installed on the outside of a bar to connect it to a garden where it acts as an AccesPoint (DHCP has been disabled). and another cpe210 as a client. The problem is that for some time to let him exchange data, he has to switch it off and on again after which it works for a few hours and then stops again, do you think the TP-Link is broken?

It is difficult to diagnose this from far away. You could test it in an isolated environment (such as your office/lab) to make sure it's not the environment which causes disconnects for some reason.

Did you properly ground the CPE? If not, changes are that it could have been destroyed by atmospheric discharge during a lightning storm, which in my experience is the topmost reason for defects of CPEs. If grounded, CPEs usually work uninterrupted for years w/o problem.

BTW: there is an own forum for Pharos devices.
