Starting speedtest using auto-selected server for WAN interface. Please wait...

I'll be issuing a new spdMerlin release version sometime in the next few days.

@itibi,

While waiting for the next production release, you could switch from the master to the *develop* branch, which has the fix for the problem you're experiencing:

/jffs/scripts/spdmerlin develop

If you do the switch, let me know if the problem gets resolved in your router.

Once the next production release is available, you can switch back to the *master* branch:

/jffs/scripts/spdmerlin stable

HTH.

Release Notes for spdMerlin v4.4.10 production version now available
[2025-Jun-08]

1) FIXED: New code to remove duplicate parameter key names found in the configuration file. Getting duplicate key values can cause "bad number" or "arithmetic syntax" errors.

[Thanks to @itibi for reporting the problem]​

2) FIXED: New code to display correct numeric values when download or upload data units are in GB or KB.

[Thanks to @Tarek Yag for reporting the problem]​

3) IMPROVED: Added code to create a separate logfile to capture the SQLite3 errors with more verbosity.

Debug logfile default location: /opt/share/tmp/​

4) Miscellaneous code improvements and fine-tuning.

Thank you very much! I'm switching back to stable branch right away!
@Martinski, @ExtremeFiretop, appreciate y'all!

Hello again,

I'm reporting again regarding the numeric values bug I reported a few days ago. Today, while I was having my usual look at the latest automatic Speedtest results it came to my attention that numbers are showing consistently incorrect again!
So, I immediately made a few manual speed tests, but processing the numerics showed random results (alternating between new and old display) with no specific pattern that I could recognize for troubleshooting.

Moreover, for more troubleshooting, I tried switching between built-in and external Speedtest binaries (spdMerlin v4.4.10) to no avail, so I went with a first impression that it's caused by having multiple code paths for processing numeric values and the bug fix isn't applied to all code paths, or it could be some bug with processing Speedtest result's text itself. And I was about to report this first conclusion.

Anyway, I had an idea to try and check if there's any new code in the develop branch, and to my expectation, there was (v4.4.11)! I made more speed tests and the bug vanished completely with both Speedtest binaries (since there's a new external binary with the new version in development).

However, I thought it could be helpful to drop this information here for you guys, @Martinski, @ExtremeFiretop. It might be a bug you're already working on and/or already fixed.
Attached is a screenshot from my Last X Results table, showing automatic test results at the very bottom, then some test results with v4.4.10, then at the very top some test results with v4.4.11.

EDIT #1 : Re-wrote some points for clearance. Added more details.
EDIT #2 : Mentioned members.

Thank you once again for your hard work!

A doubt I always has - what's the difference between the built-in and external binaries? And which should we use, which is the best and why?

I don't have sufficient knowledge of the inner workings of the Speedtest binaries to provide meaningful answers to your questions.

Would it be possible to add tags and releases with the changelog to the AMTM-OSR github repos? Right now the most recent tag for AMTM-OSR/spdMerlin is 4.4.5 from Dec 2022, and there aren't any releases or changelogs at all. Adding releases would be helpful because then I could watch the repos on github and get email notifications with the changes when a new release is pushed.

It's one of my action items for the team, I think I brought that one up about 2 weeks ago. It's currently pending @thelonelycoder and @Martinski to review in our private discussions and provide feedback. It's on the list of many things but will get done eventually, it just got pushed back by other more priority things.

I've always had this question in my mind since the first day I started using spdMerlin.
But, since I started realizing how outdated my RT-AC68U is, and experienced a few bugs that I helped troubleshoot and fix in DomainVPNRouting script, specific to my router's model; that's when I've got the ultimate answer.

The external library right now will always be newer than the built-in library I have on my router, as my router's Merlin firmware has reached it's EOL last year, hence, no more Merlin firmware updates and no more library updates for anything.

However, for the newer router models and firmware versions, the external library could be upgraded ahead of the firmware's built-in library for several scenarios and for several reasons. I'll keep this for your imagination.

Moreover, from a Software Engineer's perspective, it's always good to use the latest stable version of any software and/or libraries
