After replacing D-Link outdoor AP with LAP1522AG (3 AIR-ANT2450V-N type antennas)there is no stable wireless connection at the corner of the house opposite to AP because of the weak signal. AP is connected to 220 V AC.
Current Tx Power Level - 1, 28 dBm.
Is there a way of increasing transmit power? Maybe changing country code whose maximum dBm is more than 28 ?
