Hi,
I have Mikrotik Omnitik POE 5 ac,
the documentation says it supports 31 dBm,
I’m setting the Tx power to 31 dBm, but the maximum power I get is 22 dBm.
Please advise, how to unlock the full power?
.
The screenshots are below:



This will most likely be illegal in your country and you could get into trouble. The actual output power is limited by the “Country” you have set in wireless settings.
Re: … the documentation says it supports 31 dBm …
Read the wireless specifications on the Mikrotik OmniTIK 5 ac
The documentation indicates that at a 6MBit/s transmit rate it supports a transmit power of 31 dBm.
It does not say that it has a transmit power of 31 dBm at all transmit speeds.
6MBit/s transmit-dBm: 31 Receive-Sensitivity: -96
54MBit/s transmit-dBm: 27 Receive-Sensitivity: -81
MCS0 transmit-dBm: 30 Receive-Sensitivity: -96
MCS7 transmit-dBm: 27 Receive-Sensitivity: -77
MCS9 transmit-dBm: 22 Receive-Sensitivity: -72
So yes , the documentation is correct if you read the specifications.
Note:
- Most wireless devices will initially connect at the slowest connection rate.
- After a connection is established , the microwave devices will periodically automatically try to upshift to a faster connection rate ( which has a weaker tx power and a less receive sensitivity.
- If the new upshift to a faster rate is stable , it will again upshift to a faster rate ( again weaker tx & rx – but faster ).
- If the new upshift to a faster rate is not stable , it will down-shift to a slower connection ( more tx & rx , more stable – but slower ).
This is how almost all microwave devices work. The connection will upshift and downshift depending on the signal quality.

6MBit/s transmit-dBm: 31 or 54MBit/s transmit-dBm: 27 - is exactly what I need, but it only provides me 22 dBm max, which is not enough. The AP is in the rural area, no one around could be affected. I did this before with another vendor, and it works for years, no issues with the law.
@TomjNorthIdaho, In the Interface List section I can see the following:
managed by CAPsMAN
channel 8525/20/ac(22dBm), SSID CKP, local forwarding.
even though I configured it for 31 dBm.
it works, but only for like 15-20 meters, and this is an outdoors device, I need it to cover 40-50 meters outdoors, which I think is possible, if I could unlock the dBms to the full power.
It is annoying to figure out how to increase the power output. Haven’t been able to do that on my L009UiGS-2HaxD-IN yet.
The specs (https://mikrotik.com/product/l009uigs_2haxd_in) and country’s restriction says it can go up to 30dBm, but the most it shows at the moment is just 2/3 of that, 21 dBm if to be precise:

Tried to play with

and

but to no avail.
What happens if you set “channel.band=2ghz-n” and channel.width=“20mhz” ? And only one of these (leaving the other as you currently have it)?
Already have for the former and did try for the latter, but to no avail. It almost looks like the RouterOS ignores the channel band and/or width settings and does its own stuff.
Currently configured as follows:
/interface wifi configuration
add ...
add antenna-gain=0 channel.band=2ghz-n .skip-dfs-channels=10min-cac .width=20/40mhz-eC country=Canada datapath=datapath-vlan300 disabled=no mode=ap name=cfg-wifi300 \

set [ find default-name=wifi1 ] configuration=cfg-wifi100 configuration.mode=ap .tx-power=30 disabled=no security.connect-priority=0
The output for the master wifi1 is above, and for the second wifi - wifi300 - is below:
> /interface/wifi/monitor v-wifi300

Wifi Explorer confirms that as well, see the attached screenshot:
- the last line, selected with blue cursor, is
wifi300; - the second, highlighted with yellow -
wifi100, which a laptop is connected to.

Environment:
- (for simplicity) 10x10m, or 100m2 (1000 sq ft) per floor, square house;
- standard Canadian framing, i.e. plywood & drywall;
- the router is in a basement, measurements are on the second floor;
- ISP’s modem (Actiontec T3200M) with embedded wifi and internal antennas covers the whole area just fine (but doesn’t support VLANs unfortunately).
The settings I mentioned can be set in two locations: directly on wifi interface or in channel profile … so check both places.
the wifi interface config is above.
As for the channel profile(s), they aren’t assigned, why should it matter?
But here is that config:
/interface wifi channel
add disabled=no frequency=2472,2432,2417 name=ch-2ghz width=20mhz
add disabled=no frequency=2472 name=2ghz-ch11 width=20mhz
You have channel.width and channel.band set in wifi configuration profiles …
BTW, settings, which affect physical radio interface (frequency, band, width, Tx power, etc.) are only applied on master interface … setting them on slave interfaces doesn’t make any difference (and can be thus misleading).
yeh, I suspected that. Thanks a lot for confirming!
