AP Bridge Mode (SXT Lite5) License

RouterOS General
1

Hi,
Hope you all are doing well. Recently I have purchased 2 SXT Lite5 device to connect two lan network at the distance of 1km-2km.

I tried to select AP Bridge mode but its saying:
“Could not change interface - license does not allow ap mode 6”

Here is the device information:

/system license print
       software-id: KHGM-GZSJ
       nlevel: 3

I believe that this license will not going to support “ap bridge” mode. Is there any other way (station or bridge mode or etc) to use these devices to connect 2 networks at the said distance?

Thanks

If only one client device is enough for you, use “bridge” mode.

Thanks mate.

You mean I can use one device as bridge? What mode should I set to the another device? Station WDS? Can I be able to connect 2 networks by this method?

Thanks

I’d say “station” or “station-bridge”, see here what you need.

Thanks again

So what i need is this:
Clients (192.168.1.x) —> Bridge ← - - - - - - → Station Bridge <— Clients (192.168.1.x). I think this one.
OR
Clients (192.168.1.x) —> Station Bridge ← - - - - - - → Station <— Clients (192.168.1.x).

Is this scenario is ok? 192.168.88.1 , 192.168.88.2 are set on the devices or can be on the same subnet as clients are.

Thanks

First one. And remember, this is just configuration of the link itself. If you want to have one big network as it seems, you need to remove default configs and bridge wlan and ethernet interfaces together. And yes, you probably want to use same 192.168.1.x addresses for SXTs, unless you have different network for management.

Thank you

I configured 1st scenario and its seems to be working. I can now connect (or ping) to the clients (192.168.1.1), the Mikrotic devices IP’s are 192.168.88.1 (Bridge) and other is 192.168.88.2 (Station Bridge).

I hope that it will cover the distance of around 2-4KM.

Is there a way to check how much distance it will going to work?

If this scenario is working then why AP Bridge mode is needed?

Thanks for the support sob.

If it’s going to work or not, MikroTik has a calculator somewhere, which allows you to compute theoretical signal levels and I think speed too. But until you actually try in real world, you can’t be sure.

Difference between “ap-bridge” and “bridge” is that the latter is limited to only one client.

I have implemented the station bridge and bridge mode. The CCQ is 90%±, the distance is around 500 meters. But I haven’t chosen any protocol yet, maybe I’ll set 802.11.

Thank you

Here’s a very clear link test with valuable configuration for a pair of SXT on a 1km link.

Thanks for the link.
