FingBox Internet Speed Test is wildly inaccurate

Busta999 · June 26, 2020

I have 930Mbs down and 130Mbs up which FingBox reports as 102Mbps and 83Mbps respectively.
FingBox did seem more accurate when I had 70/20mbs service but seems to lose the plot as the speed increases.
Any forecast when this will be fixed?

Hi @Busta999 , Fing uses m-labs for speed testing. Can you please check if M-Lab speed test is the same from link below?

Looking to see if its a fing issue or their testing provider...

Busta999 · June 27, 2020

Thanks.
M-Lab speed Test returns the same.
The Ubiquiti Speed Test reports 350Mbs/100Mbs
BT reports 930Mbs/130Mbs.
So not sure why such a large discrepancy.

I can also confirm I see very large discrepancies when using the Fingbox v1 & v2 versus the link you provided. I have 1Gbps synchronous fiber and the Fingbox always tests at around 500Mbps or less. I have tried multiple cables and boxes to with the same result. This really needs fixed as it is not a new problem.

@Rhinoroo , are you saying you see internet speed test differences between m-Labs and what you see when its done via Fingbox?

Rhinoroo · June 30, 2020

@Marc , Yes - I can confirm that and just assumed Fingbox was not capable of testing at speeds above 500Mbps because it never tests higher than that. Unit is directly connected to primary 48port Unifi Switch at Gigabit Full Duplex as reported by both Unifi controller and Fingbox.

That should not be from what I've read (Though I could be wrong). Tagging @Robin and @Ciaran from Fing for comment.

If it can help, I have the same behavior in Germany with my cable connection. With my 400/20 earlier, the speed tests were pretty accurate. Since I've moved to 1000/50, the fingbox wasn't really able to go over 550 Mbits during speed tests. I thought it was ok, since my windows server didn't show pretty much... But my provider has now a test which is testing also the perf to the modem and it shows me most of the time over 1000 available. I installed a Linux on a laptop to check without windows, directly connected to the router... and I'm getting 940/50 with my provider test. Speedtest.net give me also round about 940/50... And MLAB more than 870/50.

I've now plugged my Fingbox v1 directly to the router where my laptop was... Speed test 470/45, but even worse 101ms ping, were all other tests gave me between 10 and 20ms.

Is the Fingbox really able to test gigabit Links ?

Is there a way to "reset" / force upgrade the box ?

Rhinoroo · July 14, 2020

I would love to see someone from Fing weigh in here.. @Robin or @Ciaran?

As previously mentioned on other posts, I will share the information here.
We have been in contact earlier with our Speedtest partners, M-Labs. They confirmed that they have recently rolled out an upgraded of their infrastructure & migration of machines to a new platform. This is being done to improve the overall Speedtest performance going forward. By doing this, initially they have cut of the multi-stream download Speedtest that we rely on for our Speedtests. However, they have greatly improved the single stream download Speedtest (previously the single-stream download could measure up to 250 Mbps, where now it can measure up to 500+ Mbps). With speeds above this, the measured speed reported will be lower than before, due to the single-stream limits.

To note for Fingbox users: this will also affect Fingbox Speedtests. We have released a new firmware version for the Fingbox which will allow single stream download to work again, firmware version 1.14.13 and onwards. If you have not yet received the new release, please power-cycle the Fingbox, this will automatically update the firmware on the Fingbox.

M-Labs are working on re-introducing the mutli speed download speedtest, to include it again in the future. Currently, we have no time-frame on when this will be re-introduced. Unfortunately at this stage, there is no further steps we can take to expedite this process.

Also, I would like you to try some new CAT 6 or 7 cable with your Fingbox and see if that makes a difference. Thanks

Is Fing testing and/or migrating to the new M-Lab NDT7 protocol that could be fixing this speed test issue with Fingbox?

That is the partner we use for speed measurement, so if Fing results are not in line with the ones reported by M-Lab, we definitely have to fix something.
Please run the speed test from Fing desktop as well to compare the test results with Fing app and M-lab website and share the results with us so I can investigate further? Thanks

DoomSwitch · September 1, 2020

I'd like to weigh in here also. My speed tests have always been seriously inaccurate. My actual service speed is 200 MB/s however Fingbox consistently tests around 60MB/s. It has been like this at two different locations over the past 4 years. My current FW version is 1.14.18, however, the same experience.

@DoomSwitch , did you try @Robin ’s link above for Mlabs and if so what was the output? Did it match what Fing reported?

Here is my output (keeping in mind there is some peak usage right now. I have 1GB/1GB fiber service and usually hit 950/950 sustained xfer rates.
FingBox v2 (most inaccurate and biggest issue) - This test has NEVER been accurate.

@Robin can someone weigh in on my reply above?

Still waiting on an official response @Robin

Have you checked with a different ethernet cable if results vary or not? I am trying to replicate the issue but my Fing desktop, Fingbox are showing similar results. I am trying to replicate but I need some more info which I can use to isolate the issue. Does the speed test on Fing app(without Fingbox) show different results which are close to Fing desktop?

Rhinoroo · December 4, 2020

@Robin
I can confirm that I have tried multiple cables (Cat5e, Cat6) directly connected primary switch (confirmed 1gbps negotiated rate) and I am still seeing the same result.
The Fing app (wireless) will not show similar results as hardwired Fingbox so I am not sure that is a valid test. Other tests as indicated above do reflect different results.

XDAndy · December 13, 2020

Just to add to the conversation, got the same issue.

my ISP just upgraded to synchronous 1 Gbps, but fingbox still shows speeds approx 500 Mbps.

If I connect my MacPro to my router using same Fingbox cable, I get results from Madrid (few hundred miles away) close to 1Gbps using SpeedTest

But if I change the server to Lisbon PT, seems Ookla Speedtest has a server with them as well, it drops back to 500 Mbps

So, perhaps the test server is the issue, not the test software?

Thanks @Robin, I appreciate the explanation and am looking forward to a resolution in the future.

Rhinoroo · December 15, 2020

@Chris_MLAB, are you able to provide an update on when multi-stream testing can be made available again?

OU812 · April 20, 2021

Any update on this as I’m getting really strange results?
