Dear @Bazreplay,

Just recently put up another ap mode cpe510 to redirect internet to another building from existing cpe 510 witch is working perfectly .but after 2 days the client on the new one drops out I have to unplug and plug in again then it's fine again for another 2 days any idea what would course this.

It is suggested to check the firmware and power supply, make sure they are running with the latest firmware, and not suffering from power shortage. If possible, try accessing the Pharos page when it drops out, check if it is accessible via LAN connection before you restart it.
