Upgraded Beryl AX (GL-MT3000) to 4.6.4 (2024-09-04) — Low Upload Speed When Using Repeater Mode

Technical Support for Routers

Recently, after the release of firmware version 4.6.4 (2024-09-04), I upgraded my Beryl AX (GL-MT3000). Previously, I was on version 4.6.2 (2024-06-28) without any issues.

Here are the details of my setup, symptoms, troubleshooting, and configuration:

  • I’m using the repeater feature, repeating a 2.4 GHz Access Point on Channel 1.
  • My wireless configuration has both 5 GHz and 2.4 GHz enabled for Private and Guest networks.
  • Each network has different SSIDs:
    • 5 GHz - Private (SSID1)
    • 5 GHz - Guest (SSID2)
    • 2.4 GHz - Private (SSID3)
    • 2.4 GHz - Guest (SSID4)
  • I am using additional features like VPN (excluding the Guest VLAN), DNS over TLS (DoT), GoodCloud, and DDNS.
  • For troubleshooting, I:
    • Disabled all additional features.
    • Rebooted the device multiple times.
    • Configured the 5 GHz band for wireless connections and kept the 2.4 GHz for the repeater.
    • Reset the router to factory settings.
      None of these resolved the issue.
  • The slowness is only temporarily fixed when I disconnect and reconnect to the 2.4 GHz Access Point acting as the backhaul. However, the issue reappears within minutes.
  • Finally, I reverted to firmware version 4.6.2 (2024-06-28), and everything is working fine now.

I’m unable to test upload speeds with a wired WAN connection since I don’t have one available.

May I know how many speeds when it reconnects repeat to the 2.4 GHz and how many when it a few minutes later?

May I know what the 2.4GHz configuration of the primary router?

I brand-new install the v4.6.4 firmware in the MT3000, seems it is ok and tested over 20 mins.

May I know how many speeds when it reconnects repeat to the 2.4 GHz and how many when it a few minutes later?

  • more than 50Mbps Upload and more than 50Mbps Download after reconnecting. And a few minutes (maybe half an hour or less) it will go down to <0.70Mbps Upload and download will remain the same at about >50Mbps (the speed is asymmetric, sorry did not mentioned that on the original post)

May I know what the 2.4GHz configuration of the primary router?

  • its managed by our building admin basically its an open 2.4GHz access point with a landing page/portal. I also did a AP scan and its in Channel 1, 20Mhz Bandwidth

I see, I have tried to reproduce this here but not happen, the repeater works well.

Could you please try to disable some features only leave the repeater, to see if it works?

Yes i also did this as a troubleshooting step, i disabled ALL feature and only use the repeater option.

I also did a factory reset but still not resolved.

What resolved it is i downgraded to the previous version and now it’s working well.

Also, i did notice that one of the changes in the latest version is the updated wifi driver. Im not sure if this is the cause of it.

Can you try this firmware?
thank you

I have the same issue. Just installed and download is about my broadband max (70mbps) but upload is 0.5mbps when should be 18-20 meg.

I updated as brand new and onto that same firmware...I will try that linked firmware too and see ...wish me luck

Hmm I thought the 4.7.0 version linked above had fixed it. I tried some speedtests and 4 or 5 times it was fine. Closed everything down and then did one last test...everything back to 0.5mbps upload again. Tried disabling 2.4g in case that and still same or lower on 5g wireless.

Whatever worked seems to have reversed ? I cant use this now for tomorrow unless I can find an older firmware it will let me upload...great !!!

UPDATE: I found the older firmwares here

So far reverting to 4.6.2 seems ok again but will keep testing. NOTE: Installing this after the 4.7.0 one above from Support will wipe your settings!

Hi, does the op24-v4.6.6 of MT3000 Wi-Fi speed improve? If the speed does not improve, please share the syslog to us and let me know what firmware version uses.

I went back to v4.6.2 and that has retained the full upload speed during the weekends event I was running and whilst tested this week at home piggy backing my own unifi wifi.

So yes there seems to be an issue with upload speed on repeated wifi network after that release somewhere.

I did still find an issue I've had two years running a public event that there seems to be consistent dropouts from the router (repeater connected to event wifi) which reconnect say a minute later. This is very odd and now across two different locations/wifi networks and several different pc, laptop and mac devices ?!

Reading around the web there is talk of it being connection issues with the repeated wifi you are connected to but I cant reproduce this at all on my unifi home wifi? Only difference I have is a printer ethernet connected to share from back of router in these events...maybe I will test that.

The logs doesnt show back to weekend unless someone can show me where to grab elsewhere ?

Extended log record and extend it as long as it can:

uci set system.@system[0].buffersize=204800 
uci set system.@system[0].log_size=600   
uci commit

Probably related to the primary router wifi, but need to confirm by the syslog.
