mANTbox ax 15s increase radio power

RouterOS Wireless Networking
1

Hello guys,

I have a mANTbox ax 15s installed with default parameters at a friend of mine. The country is set to Netherlands and left the other fields blank.

The problem is that my friend is complaining about low reception at approximately 50meters from the access point.

I saw that tx-power is set to 7 for 2.4Ghz and 15 for 5Ghz.

According to ETSI rules the maximum on the 5540 frequency is 27dbm.

Is it possible to increase the tx-power a little bit without creating more problems?

Antenna gain dBi for 2.4 GHz 12
…
Antenna gain dBi for 5 GHz 15

So, not really.

But low reception at 50 meters is definitely not normal, the mantbox Ax 15 s is (should be) capable of km links.

A couple of (good?) questions are:

  1. what does your friend mean by “low” reception?
  2. and what are the device(s) on the other side of the Wi-Fi link?

Indeed, but probably I am doing something wrong.

My friend is using an Android phone. He wasn’t able to see the WIFI network from that point. The Antenna is at 3 meters high under a vertical angle of 10 degrees below.

I left the tx-power and antenna-gain unset, because according to the documentation it should be sending max allowed.

Do you know where I can find out what the values antenna-gain and min_antenna_gain(is blank in CAPSMAN) are currently set to, so I can verify it is set correctly?

It’s correct when following the standards. Max allowed power in your country minus the antenna gain (around 12 db on 2.4G and 15 db on 5G).

No idea, but are you using CAP/CAPSMAN for a single access point?

3 access points in total.

  • 2 mANTbox ax 15s AP’s
  • 1 indoor AX AP.

on 2.4 GHz they have the channels 1,6 and 11.
on 5 GHz they have the frequencies 5180, 5500 and 5540.

I see :slight_smile: , you are right on the convenience border between using or not using capsman:

Nice SSID in that post. NoPain-NoGain :smiley:

It looks like he is using Capsman v1 which will not work on AX access points right?

My friends setup is working fine, but need some tweaking. I just want to verify the antenna_gain and min_antenna_gain is set correctly, but don’t know where to find it. Also /interface wifi print detail won’t show me.

Hi,
I have the same problem, radio power of mANTBox ax 15s est very poor, in comparison to what Mikrotik claims.

My old year 2016 indoor WiFi router Asus RT AC66U with 3 small antennas, from inside, transmits outdoor almost as far as the mANTBox ax 15s. See the tree http://forum.mikrotik.com/t/new-in-routeros-v7-15-3-especially-on-mantbox-ax-15s-i-have-troubles/177708/1

I wonder, if there are users who have purchased this product and can use it at distances of 100, 200,… 500m?

I echo these statements. Deployed mANTBox 15 ax to replace an existing “AC” Wifi5 Access point that took a lightning hit. The mANTBOx 15 AX is poor replacement.

Appears antenna-gain related issue with RouterOS

hello I have the same problem. Did you solve the problem?

Same issue here, 3 mantbox ax on a mast. Around the mast there is no ssid seen on devices. Only at longer distance (like 100m) you can see the ssid.
The mantboxes are managed by capsman. Annoying too is that you can’t even use channels without DFS, like 5180, it’s not accepted.
Compared to the old mantboxes, it’s a major disapointment…
Did anyone get it to work for like in a field on a campsite, or a citysquare. In other words, not only used with long distance routeros client devices?

Still issues here as well. Open ticket with MIkroTik. I have a SUP and they finally responded with some bullshit reply. There is an issue and they refuse to take it seriously.
