Maximum transmit power

Hi,

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 ?

The hardware in the 1522 does not allow for a change in country code in that sense. And even if it did, you probably wouldn't want to make a habit of breaking regulatory laws :)

You likely have two options - install another AP, or install larger antennas. You could consider installing a AIR-ANT2480V-N, which is 3dBi stronger. See more antennas here:

Just to double-check, do you get a really strong signal at close range? Just want to confirm that the AP is working appropriately on the off-chance that it's not broadcasting at all, and maybe you're just picking up another AP from further away.

Actually there are no working regulatory laws in the town the AP is installed and there is no code of the country in the list. So I thought it wouldn't be a problem to get the maximum power from the AP :)

DLink replaced was working with full transmit power at the same place and there was a stable signal in that particular corner, so it would be good if the problem was resolved with one AP.

AP is working properly, I see AP MAC address in Netstumbler. Is 28 dBm the maximum value?

And is it necessary to install 3 AIR-ANT2480V-N antennas (1 tx, 2rx) or installing AIR-ANT2480V-N as tx and 2 AIR-ANT2450V-N as rx is also possible?

TIA
