Question how to create WLAN Brdige with 2 MikroTik SXTsq 5 ac

Hello everyone,

I have the following situation: House A has an internet connection. House B does not have an internet connection. The two houses are only 500 meters apart, and there is a clear line of sight between them. I bought two MikroTik SXTsq 5 ac devices to set up a wireless bridge.

I am going to mount one on each house and align them with each other. My question now is how to configure them properly.

I started by mounting and configuring the first device at House B, but suddenly it became unreachable. Running ipconfig, I got the following output:

Connection-specific DNS Suffix .  : 
Link-local IPv6 Address           : fe80::1e91:e1a9:9e88:7c64%9 
Autoconfiguration IPv4 Address.   : 169.254.164.89 
Subnet Mask                       : 255.255.0.0 
Default Gateway . . . . . . . . . :

I could see the device was still somehow connected, but trying to access 169.254.164.89 only resulted in a "Connection refused" error. This is pretty frustrating, because now I have to climb back up the ladder and struggle to press the reset button. I guess it’s a much better idea to fully configure everything on a desk first before mounting them!

Anyway, I assume my setup is a very standard point-to-point scenario. Is there a simple step-by-step guide somewhere that shows exactly what needs to be configured on the MikroTik SXTsq 5 ac for House A (with internet) and House B (where the internet should be available)?

Basically, I just want it to run reliably and don't really care about any of the advanced features.

That is an APIPA address, essentially the device is looking for a DHCP server, but cannot find any and tries to make a temporary address.
Whether the device will (or won't) respond depends on configuration.
While it is always a good idea to make at least a basic configuration on the desk[1], not everything is lost, usually (unless you mis-configured something) a device is reachable by Winbox using MAC address.

See (point 3.b):
Why you should use Winbox

[1] Particularly when we are talking of PtP connections of devices mounted on poles or on a roof ...

Indeed.

Never setup these devices, but I think the simpliest method is to use QuickSet:

  • House A: Quickset mode PTP Bridge AP
  • House B: Quickset mode PTP Bridge CPE

see Quickset modes: Quick Set | RouterOS Manual

Hello everyone,

I set up the first device (MikroTik SXTsq 5 ac), which is connected to my internet router. But after I clicked "save", I could no longer find or access the device—neither via its MAC address nor its IP address.

I then really tried to figure out how to reset this device to factory defaults. OK, there is a reset button you are supposed to press and then release, but exactly when to let go is described as vaguely as possible. And apparently, there are different timings for releasing the reset button that trigger different modes.

I would really appreciate it if there was a manual specifically for this exact device, rather than a generic guide for all MikroTik devices combined.

Maybe I'm just being stupid and don't get it. But my usecase is basically the most straightforward, standard scenario, and it really should just work. But once I configured the "House A" device, I couldn't reach it via MAC or IP address anymore. It seems like it's just gone.

There must be at least someone in this forum who has successfully managed such a simple, straightforward setup.

Is there a PDF guide somewhere that actually makes sense? I haven't given up yet. Maybe there is some kind of customer support? I did buy four MikroTik SXTsq 5 ac devices, after all, so I would hope to get some help.

The timing may be different, but the reset procedure Is the same.
There are two bootloaders, one Is triggered when power Is applied after pressing and keeping pressed the reset button, the second when the reset button Is pressed immediately after applying power.
The exact moment when to release the reset button Is when you see a led starting to flash but It Is not very strict, only if you insist for some 5 more seconds the device will shift to caps mode.
