New in RouterOs v7.15.3, especially on mANTbox ax 15s, I have troubles

Hi Everyone,

I have just purchased this station and I have major configuration problems.
I am a beginner and I have trouble with WinBox and RouterOS. No correct documentation (or non-existent) and for the settings (variables, values) there is not much on WinBox, or they are old versions that do not correspond to my v7.15.3.
My network diagram is simple, two routers in series, one switch where are devices.:

  1. ISP Router IP: 192.168.1.1 →
  2. wire connected to ISP Router, my “Tp-Link DecoM5” and its IP is DHCP acquired, DecoM5 is configured to Router Mode for 192.168.168.1/24 with DHCP Server (all devices connected are in this range)->
  3. wire connected a Netgear G S305E switch to my Tp-Link DecoM5
  4. On the Netgear switch I plugged:
  • 2 pieces Deco M5 (Mesh working)
  • the Mikrotik mANTbox ax 15s (192.168.168.247)
  • and devices (TV, AndroidBox, printers, PV inverter, etc. and I reserved IP addresses in DHCP)
    All roaming devices are connected by DecoM4 mesh WiFi (2.4 or 5GHz)

First time, I followed steps 1,2,3,4 of the RouterOS default script:

#| Welcome to RouterOS!
#|    1) Set a strong router password in the System > Users menu
#|    2) Upgrade the software in the System > Packages menu
#|    3) Enable firewall on untrusted networks
#|    4) Set your country name to observe wireless regulations

In WinBox, Quick Set I have only Home AP.
Here, I can’t enter in Local Network the IP Address: 192.168.88.1 or other IP with their Netmask and check DHCP Server and the range, after Apply and OK button mANTbox lose the network, unable to connect to mANTbox. I tried at least 30-40 times, it’s the same.
Every time I must make a hard reset on the mANTbox to try again with, with another values, settings.
If I do not complete the Local Network section, and I close the window (this means that it is my DecoM5 router that distributes the IP addresses for mANTbox clients), I can change settings in Interfaces, WiFi, etc. WiFi 2.4 and 5GHz works but the tx-power is verry poor, 20-40 meters.

If I fiddle with WiFi settings in the Configuration tab, I can increase the tx-power, but either WiFi 2.4 or WiFi 5GHz does not work anymore.
I need a distance of about 250m practically free of any obstacles, no neighbors.

My first question: how to configure the mANTbox in AP mode to working in a separate network from my DecoM5 router, DHCP in 192.168.88.0/24 for example.

Others questions later, for range adjustments (what are variables Chains, Tx Chains, Tx Power, Antenna Gain, etc.)

Thanks for your help

Sure, the documentation is often scarce, and particularly with newish releases changes take some time to be (if ever) documented but did the Mantbox came with 7.15.3?
Or you did upgrade to 7.15.3 first thing because latest is better?
For next time the usual advice is to leave the RoS “as is”, get the stuff working (at least for the main things) and only later upgrade if deemed necessary.

Normally WInbox allows connection both through the device IP (at L3) and through the device MAC (at L2) so even if the device has no IP usually it can be accessed via its MAC, but there may be settings that prevent this.

Anyway, don’t worry :slight_smile: , what you report is pretty much normal, it is very easy (and common enough) to get locked out of a Mikrotik device the first few times, particularly with devices like the Mantbox with only one ethernet port, as an example if the port is characterized as WAN there may be a firewall rule that prevent connection and another one allowing Winbix only to connect only from LAN.

To get some meaningful help you should follow the instructions here:
http://forum.mikrotik.com/t/forum-rules/173010/1
and post your current configuration.

Thanks Jaclaz,

I followed the instruction in the first startup that is in the script !
Yes, I updated from 7.14.2 to 7.15.3

In Winbox v7.15.3, Quickset, I can’t Apply my bellow (or other) values in section “Local network”:

IP Address: 192.168.88.1
Netmask: 255.255.255.0 (24)
DHCP Server: checked
DHCP Range: 192.168.88.16-192.168.88.32

If I Click on Apply, the mANTBox ax disconnect from the LAN and I can’t reconnect.
In Neighbors I see the MAC Address, but the IP address is 0.0.0.0.
In the default script iz metionned:
:log warning “DefConf: Unable to find wireless interface(s)”;
/ip address add address=192.168.88.1/24 interface=ether1 comment=“defconf”;

In the datasheet is specified:
Two chains per band, so I juggle with
Chains 0 (HP) and Chain 1 (VP)
TX Chains 0 and 1
Antenna Gain: 2.4 GHz - 12 dBi, 5 GHz - 15 dBi
Transmission power not specified!
I entered the legal values ​​of the channels of the 2.4 and 5GHz bands.

Currently the MANTBox ax works and I am tinkering with its values ​​above for a Distance: 1km. I need 200m, if it is more it does not matter, no neighbor, to have a coverage of about 200 meters and a horizontal angle of about 15 °.

Yep, I understand what you did, and in theory It should have worked and you should have ended with the device with a basic working setup.
But - for whatever reason - in practice It did not work and you have now an only partially configured device to which you cannot connect/comunicate properly.
The normal way out from such a situation Is to manually correct what has been evidently mis-configured by the Quickset or by whatever else.
In order to do so you should post your configuration so that some members may be able to spot the mistakes/omissions and suggest corrections.

Hello, I have the same problem. Have you resolved it. What was the problem?

Hi,
No, I not resolved the problem.

I left it as it was in “Quick set”, so I didn’t put any values in the “- Local Network” section, but I played with the values in “Interface ” and “Interface ”.
I don’t need any security, routing, etc., just have a range covering about 200 meters over a width of 45-50m, but it’s impossible, I have a range of 55-60m correct, after the signal is very weak, yet the ground is clear.
In addition, I put the mANTBox at 6m high pointing down at a distance of 200m. Nothing to do, I can’t get a good signal, it’s barely 80-85 dBm with the NetSpot application and that at 70-80m. Handsome to try to point, move the azimuth and elevation and and play with values of Chains, Tx Chains, Power TX, Antenna Gain, Distance.
I even tried changing countries, only USA is barely better, I gained about 15m.

Too bad there’s no correct documentation, and the RouterOS Documentation is poor.
With my old ASUS RT-AC66U inside the house, the range was about 40m through the wall, so the mANTBox ax 15s is supposed to be 100 times better, but it is not at all the case.

I will look into other brands and I think I will abandon the mANTBox ax 15s.

Hello, sorry, they are bad news. Could you send me your basic configuration. In adicction, I dont get connect devices to internet (It is present). The local Network is configurated with dhcp. If i dont configure local Network, the devices cannot to connect (waiting for IP). Thank you

Hi,
I configured only these windows.

mANTBox ax 15s works, but the range is max. 50 meters and I want 400 meters.

I use only my smarthone and sometimes my notebook.

I don’t care about security and extras, I only use it to take care of my animals and the garden, sometimes I have to call someone to help me.

And again:

About the DHCP server, if - as it should be - you have a bridge between ether1 and wifi interfaces, and you have a DHCP client on ether1 (which means that a device connected to ether1 is running a DHCP server, BTW on the same subnet) it should NOT be enabled, the “main” DHCP server will provide addresses to devices connected to the wifi interface(s), just like it assigns the 192.168.68.247 to your ether1, having two DHCP servers running, with the same subnet is obviously not good.

About reception/transmission. I would verify the vertical orientation of the device, the horizontal angle is relatively wide, but the vertical one is very, very narrow.

    • I have Internet through the ISP router (1st subnet 192.168.1.1/24), and I have disabled WiFi.
    • The ISP router is connected by Ethernet cable to my 1st WiFi router (Tp-Link Deco M5 as Master in AP Mode) which is in DHCP mode, subnet 192.168.10.1/24 created for Ethernet and WiFi clients. The Deco M5 uses Ethernet Backhaul in Star network (

), so I have a Netgear switch, on which all the home automation and devices are connected in Ethernet, as well as two Deco M5 in Slave for the WiFi.

    • The mANTBox ax 15s is connected to the switch by Ethernet cable, it is on a mast at approx. 6m height and points at 400m ( ), distance that I would like to cover.

With the mANTBox I wanted it to distribute in DHCP in another subnet, but as described above, it is impossible. In QuickSet there is only “Home AP Dual”, but apparently it is in Bridge mode (

). Well, it does not matter, because it works and it is my Deco M5 that distributes the IP addresses for the clients.

My big problem is that the range of mANTBox is very low, 40-50m, no more than an indoor wifi router. I point out that the pointing of the antenna is impeccable, downwards at 400m distance (

). The 2 bands 2.4 and 5GHz work.

My big problem:
I do not know for the settings, how to cover a distance of 400 meters with Wifi, while MicroTik claims to be able to cover much more.

I have had issues with the MANTbox i bought as well. I setup a small very simple network consisting of a MANT and 4 Disclite6ac. One disc connects well and passes internet as soon as i connect a 2nd seems it breaks the bridge. the only solution i found after days was to go to the bridge tab and set the STP to none and everything works. the issue i have now is the network is erratic. speeds go from 150Mbps to 0 and back again. updated to most current firmware, reported it to Mikrotik and no reply. i have recreated this on the bench as well. signal level on all the CPE’s is very good and distance from CPE to Mant is only 2-300 meters.
Has anyone got suggestions on why this is happening.
I am new to Mikrotik but have setup a little of their gear. never ran into this before. To make sure it wasn’t me i asked for help from a more knowledgeable Mikrotik engineer and he was baffled. i tried a manual config and the quick set options and neither worked properly.
This is a big deal if Mikrotik isn’t responding to it
