Failing to form Link

Failing to form a PTP link with force 200. For some reason the TX power is stuck on 7 and this it could be the one causing the issue.i have tried increasing even for the SM side but no change. The airlink is just 7.5Km and the units are running firmware version 4.5. The country on the AP side is set to Other.

Any help rendered will be appreciated.

TDD or ePTP mode?
Could you please attach Monitor->Wireless Screenshot from the SM?

Thank you.
