TRB500 speeds throttling

[kernow]

Hello, I just got myself the TRB500 yesterday and i was instantly quite unhappy with the speeds I am getting compared to my old 4g router, I spent several hours adjusting my setup trying to find a bottleneck which i could not find.

Decided to stay awake through the night to troubleshoot while the networks are quieter before making plans to return it.

I am in low signal 4g area so was not expecting miracles I also was not expecting such a drop off from what I have been used to.

Speeds seem to be capped at 20Mbps down and 0.4Mbps upload.

This is repeatable with 3 SIM cards across 2 different networks. Using my phone/old 4G router in the same location gives me the kind of speeds I usually get.

There are 2 exceptions to this, My Ubiquiti wireless AP (through a TP-LINK POE injector) seems to work okay, but its not a solution. the other is with the speedtester installed on the gateway via the package manager.

any suggestions you have would be appreciated.

Here a quick test from my iPad to show what I’m currently getting through the AP

Which firmware version is your TRB500 running on?

And why is your iPad connected to another VPN when doing a speed test?

i’ve updated to the latest firmware TRB500_R_00.07.08.2

I noticed the vpn connected after i posted, But it does show that the speed is in the gateway I just don’t seem to get it to passthrough to my network switch or directly connected to my PC

[edit] just done another ipad test without the vpn on iPad 10 down 21 up.

What’s modem fw version?

[kernow]

• Internal modem firmware version

RG501QEUAAR12A08M4G_04.200.04.200

Is there an update being offered in Web UI for the modem to version 11?

RG501QEUAAR12A11M4G_04.200.04.200

If so, go for it.
People reporting better speeds with this version.

no it is greyed out… tooltip says modem updates from server are not supported

This is interesting.
Only working with RUTX50’s so can’t say if that’s ‘correct’ or not…

Can you make sure your internet connection is IPv4 only in the settings (vs. default IPv4 IPv6 auto) and post a screenshot of your mobile connection quality data (the page with green yellow red info bars on the bottom).

Sorry that I can’t post explanation-screenshots right now as RMS isn’t working for me

As for the modem firmware, I found this thread:

TRB500 modem update proceedure

This seems to be for version 08 (which you already have) but you could follow this up and ask for the v11 file?
The rest is self-explanatory I guess.

Best i can tell i’m on ipv4 only. I have left support a message to get some help.
I came across a thread earlier saying OTA updates are not available for the TRB500

i did say i was in a low signal area

[kernow]

Okay so more digging about and troubleshooting I can confirm that the problem exists on my PC only (should always test more than one device I guess)

I have switched out cables to ensure it’s not that.
I googled how to use iperf3 and speeds are as expected. (Gigabit)
I have done a Network reset within windows 11.
None of which have improved the problem.

I switched back to the old router and test shows no sign of throttling or issues with cable or ethernet ports on PC

I think I have solved it. posting a reply here for anybody in the future.

My motherboard (MSI MAG B550) included with MSI Dragon Centre software, also bundles CFosSpeed traffic shaping software (which automagicly reinstalls itself on system reboots)

getting rid of MSI software stops this thing reinstalling. more testing to do but i things are looking much better!!
