MikroTik

Posted: **Mon Jul 29, 2024 7:48 pm**

Hi everyone!
I'm experiencing random but frequent connection drops (every 5 to 30 minutes) on my new Mikrotik ax3 router. I've enabled "wireless, debug" logs, but I can't see much new information.
Here is an excerpt from the logs:

991	2024-07-29 19:25:58	memory	wireless, info		34:B3:A8:E9:D7:B8@wifi1-5GHz disconnected, connection lost, signal strength -58	
992	2024-07-29 19:25:58	memory	wireless, debug	34:B3:A8:E9:D7:B8@wifi1-5GHz disassociated, connection lost, signal strength -58	
993	2024-07-29 19:29:03	memory	wireless, debug	34:B3:A8:E9:D7:B8@wifi1-5GHz associated, signal strength -51	
994	2024-07-29 19:29:03	memory	wireless, info		34:B3:A8:E9:D7:B8@wifi1-5GHz connected, signal strength -51

The setup is basic and out-of-the-box. I only renamed the Wi-Fi ID (wifi1-5GHz) and SSID, so it's unlikely that I misconfigured something.
What could be the problem? What are some ways to troubleshoot this issue?

Sometimes a chain of disconnects occurs:

so it's unlikely that I misconfigured something.
What could be the problem? What are some ways to troubleshoot this issue?

By default WPA2 and WPA3 are enabled. That gave me a lot of problems.
To troubleshoot (together with you):
What RouterOS version are you running?
Can you share the config?

/export file=anynameyoulike

Remove serial and any other private info

Was this a problem in 7.14.x?
Have you tried disabling the randomized MAC? What kind of device is this? Have you tried increasing the lease-time? 10 minutes may not be enough.

Posted: **Tue Jul 30, 2024 2:29 pm**

.connect-priority=0

is IIRC not part of the default configuration.

channel.frequency=5650-5850

isn't either. So you re not honest as you said

I only renamed the Wi-Fi ID (wifi1-5GHz) and SSID, so it's unlikely that I misconfigured something.

But basically yes, the config is very vanilla.

What kind of device is this "34:B3:A8:E9:D7:B8"? Is it far away? Does the device report a signal strength?

Posted: **Tue Jul 30, 2024 3:02 pm**

I suggest to remove reselect-interval.

Was this a problem in 7.14.x?

I just bought the router several days ago, so it is my first version, it was the latest stable at the moment of installation.

Have you tried disabling the randomized MAC? What kind of device is this? Have you tried increasing the lease-time? 10 minutes may not be enough.

It's a Windows 11 laptop, I didn't configure its MAC configuration. Didn't try increasing the lease-time, I'll check how I can change it and will try.

Code: Select all
.connect-priority=0

Actually yes, I set up the frequency, the default one 5500 doesn't work for me, some devices couldn't find the router. I found out that in my country (Russia) there are two ranges that actually work - 5150-5350 and 5650-5850. I set up the frequency (just one range now) and the devices found the network immediately.
What about the connect-priority - I did change some settings, but I hoped I had set them back. Apparently, some settings differ from vanilla. Sorry if my original messages could be confusing.

What kind of device is this "34:B3:A8:E9:D7:B8"? Is it far away? Does the device report a signal strength?

It's a Windows 11 laptop. It's about 7 meters away from the router. There are no obstacles between the router and the laptop. On the laptop I can see that the signal is "strong". I can find some more accurate numbers if it could help

What chipset does the laptop have?

I suggest to remove reselect-interval.

There is a bug in web GUI that prevents the value from removing (quite a recent bug I suppose, maybe appeared in one of the latest versions). I just removed the value using WinBox. We'll see if it helps

viewtopic.php?t=203076#p1088442

It has an AMD CPU, so not an Intel chipset.
The problem with disconnects happen on other devices too. I don't have WinBox installed on other devices (a laptop and a phone), and most of the time I don't notice that 5-second lag, but I see them disconnect in logs as well

Posted: **Tue Jul 30, 2024 5:01 pm**

Here are many complaints about disconnects in version 7.15.x. There are several issues, some of which have been fixed in 7.16beta (but not all). That's why I asked about version 7.14.x.

Update - it didn't help, I met two "connection lost" messages in a row on my laptop just now

During these disconnects, system logs appear on my Windows 11 laptop. Here are the details of one logged event (maybe this could be useful):

As I can see from the logs, these events (with Event ID 7021) happen when a connection is established.

Once today, I had 11 connection-lost-to-connected events in a row within a minute

I also used a Wi-Fi analyzer to scan the network from my laptop, and I see that there are no other Wi-Fi networks on 5GHz (so no interference at all)

Posted: **Tue Aug 06, 2024 7:26 pm**

I updated to 7.15.3, reset the router to factory settings, and after the reset I did dome configuration:
Using "Quick set" feature I configured 2 Wi-Fi networks with same SSID "DIR", set up the password, didn't set up the country.
After that I configured the frequency of the 5GHz network to 5650-5850, disabled WPA3 PSK, leaving the WPA2 PSK enabled. Enabled debug logs. Set up the "Reselect Interval" to fix that GUI bug.
Still see disconnects and still have no clue what's going on and how to troubleshoot it

Here is the config I have right now:

I'm experiencing the same issue. I also have the MikroTik hAP ax3, but setup as a switch and access point, as i have the RB5009 as the main router. The ax3 is running RouterOS 7.15.3 and wifi-qcom 7.15.3.

This is my config for the ax3:

/interface bridge

Can you try setting encryption to, mbach:

encryption=ccmp,gcmp,ccmp-256,gcmp-256

And use wpa2-psk only.

And enable debug, wifi logging to get some additional information.

Posted: **Thu Aug 08, 2024 7:23 pm**

Was having the same issues - tried all the "fixes" suggested all over the forum and just about any other setting I could think of but nothing solved this.

In the end I did a downgrade to 7.14.3 and all is working again as expected without issues.

Posted: **Thu Aug 08, 2024 7:53 pm**

I've updated both WIFI to the following:

/interface wifi
set [ find default-name=wifi1 ] channel.skip-dfs-channels=10min-cac configuration.country=Denmark .mode=ap .ssid=mbach disabled=no security.authentication-types=wpa2-psk \
    .connect-priority=0 .encryption=ccmp,gcmp,ccmp-256,gcmp-256 .ft=yes .ft-over-ds=yes
set [ find default-name=wifi2 ] channel.skip-dfs-channels=10min-cac configuration.country=Denmark .mode=ap .ssid=mbach disabled=no security.authentication-types=wpa2-psk \
    .connect-priority=0 .encryption=ccmp,gcmp,ccmp-256,gcmp-256 .ft=yes .ft-over-ds=yes
/system logging
add topics=wireless,debug

Also updated logging to include wireless and debug, but it does not seem to have changed anything:

I can concur, had no issues on 7.14.3 but upgraded yesterday and am now seeing disconnects. Any word on any improvements 7.16 might bring?
