GL-SFt1200 repeater mode doesn't work

Sergius · 2022-12-23T06:27:08.086Z

It seems that the problem is only in the 2.4 GHz band. In 5GHz repeater mode, the router works great!

alzhao · 2022-12-23T10:54:21.353Z

2.4G is more prone to interference. Let’s keep using 5G.

“I reside in Tiga and am currently the only resident. Your device is not functioning in 2.4 repeater mode.”
“The parenting device indicates that it is experiencing significant data loss, but the signal strength is strong at -59.”

It looks like the problem only occurs with MikroTik routers. I have tried different models but the result is the same - in 2.4 GHz it does not work as “Repeater”. SFT1200 constantly loses connection with AP with message"significant data loss."

Sergius:

It looks like the problem only occurs with MikroTik routers.

So you mean when connecting to Mikrotik router as repeater, right? Do you have the model of Mikrotik router?

Sergius · 2022-12-26T11:07:51.267Z

Yes, when I connect to MikroTik AP in 2.4 repeater mode, it doesn’t work properly. Loses connection constantly. But in repeater 5GHz mode works fine! Tried different models of MikroTik devices. For example, MikroTik hap ac2 and MikroTik hap lite give the same result. Looks like problems in 2.4GHz-N-Band

Sergius · 2022-12-26T11:12:38.442Z

When I start checking the connection speed with the speedtest, at the begining everything goes well, then all of a sudden it loses the connection and the test fails.

wcs2228 · 2022-12-26T19:53:17.427Z

Can you do a test connecting 2.4GHz WWAN to MicroTik and 5GHz WLAN to client device? I get disconnects with 2.4GHz on both WWAN and WLAN.

I do not work for and I do not have formal association with GL.iNet.

It does not work! Constantly loses connection with AP MikroTik

GL-SFT1200 Noise level of 0 dBm does not look right. It should be -80 to -110 dBm.

Sergius · 2022-12-30T12:31:45.118Z

GL-SFT1200 Noise level of 0 dBm does not look right. It should be -80 to -110 dBm.

It appears to be a software bug that does not show the actual noise level.

Sergius · 2022-12-30T12:38:26.206Z

At first I thought everything was ok in 5GHz, but now I see the same problems in 5GHz repeater mode. In this mode, GL-SFT1200 simply does not work. And I do not see any help from Technical support. This router is really raw.

alzhao · 2022-12-30T16:19:08.569Z

We will get a Mikrotik AP and test.

Sergius:

Error, msdu index reach maximum limit, 31

Looks like problem is here. MSDU - agreation method for service data. This method performed in hardware.

alzhao · 2022-12-31T02:20:43.332Z

@dxf can you have a check of this log?

Sergius · 2022-12-31T12:20:45.368Z

What are you asking for? I can’t realize!

dxf · 2023-01-05T07:43:28.528Z

Pls try changing the wireless AMSDU Limit in MikroTik to 2048.

and then, setting the dhcp server lease time to 12 hours.

see if there is any improvement

Sergius · 2023-01-05T13:28:14.925Z

Thanks for your help. Now it works great. But in fact, this needs to be done on the Gl.Net side. Sometimes it can be difficult to ask someone to change their hotspot settings.
