Many thanks Mr Weaver I need to have a good read. Alas I also have an Asus router with standard firmware which is hardcoded to 1492 also and as far as I am aware no merlin fork for the DSL-N55U, there was but it is no longer being developed.

I use it all the time for i) the MTU 1508 feature, ii) for the “stats graphing”, and iii)“easy stats” over http (as I’ve named it) interface, as I’m using an iPad and so cannot run dslstats, and the stupid libraries I’m using on the iPad are limited in their support of lower level protocol functions and everything involving comms has to be http or nothing, so the ‘easy stats’ over http feature is a blessing for me. And Mr Johnson kindly wrote all these latter http based services specifically for me, after I had mentioned the limitations of the iPad.  ;D

It certainly works with Zen on TT Business backhaul.

Am I the only one having problems with both the web server, nothing showing in the stats, and the MTU size - can't ping with a packet size larger than 1464...

I'm also with Zen and I'm using Johnson's firmware 17jumbo-tel-stats-cmd. I did post a couple of screenshots here

It only works when used in bridge mode.

The router needs to support it and for it to be enabled.

Indeed the VMG1312-B10A is in bridge mode attached to a NG R7800 where both MTU and MRU are set to 1500 for PPPoE interface (see pic), what else ?

Besides, the web server stats are not showing...

webserver is broken for me also.  Seems buggy.  But I collect stats via dslstats anyway so didnt bother mentioning it.

If you could share the zip file of all gathered stats that the webserver will give you by clicking the "Save" button I could try and figure out what the issue is.

The stats server is by design very simple, you can view its source here:
https://github.com/johnson442/custom-zyxel-firmware/blob/master/stats-staging/mongoose/stats-server.c

If anything is wrong its in the javascript that parses the offered xdslctl outputs.

seems intact, I will also attach screenshot of what I see on the UI.

However it does seem to be partially working now, if I click the individual sections, SNRM, FEC, CRC all work, data works save button works, rest dont seem to work.

I had to upload zip to google drive as was too big to attach, and cannot attach a 7zip file.

If you wish it I can supply the errors from developer tools.

So initial issue seems to be with finding the vendor to apply the right split of down/up tones:

Mine is:
Code: [Select]
xdslctl: ADSL driver and PHY status
Status: Showtime
Last Retrain Reason: 1
Last initialization procedure status: 0
Max: Upstream rate = 1205 Kbps, Downstream rate = 27712 Kbps
Bearer: 0, Upstream rate = 1205 Kbps, Downstream rate = 26436 Kbps
Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps
ChipSet Vendor Id: BDCM:0xa48c
ChipSet VersionNumber: 0xa48c
ChipSet SerialNumber:

Yours:

Code: [Select]
xdslctl: ADSL driver and PHY status
Status: Showtime
Last Retrain Reason: 0
Last initialization procedure status: 0
Max: Upstream rate = 29233 Kbps, Downstream rate = 79647 Kbps
Bearer: 0, Upstream rate = 20000 Kbps, Downstream rate = 79637 Kbps

ChipSet Vendor Id: IFTN:0xb206
ChipSet VersionNumber: 0xb206
ChipSet SerialNumber: 5501843597

As I said, probably a new line that my gross javascript doesn't cope with well.

Thanks for the debug info, will look more and make a fixed version.

I apologise for putting it out with such glaring errors, but its been hard to find people to test, and having tiny errors in the JS that need a full flash suck. I have been half working on a more unified firmware, with parts stored in the /data partition that could be updated by uploading a file, without a full flash of the firmware. Got as far as accepting large uploads via the mongoose server, checking a signature and using the /etc/password file for verification. But its hard to get excited about when its such a niche device and audience.

@Johnson - My friend, I have to flash a mountain of new modems - I have just lost four from two lighting strikes in a month and I have at least eight VMG1312 B10As that need flashing - so if you wish I would be a happy tester. Would that be of help to you, if I use the latest build to flash these?

Is there a way if guarding against format variation ? Maybe by using a regex if some sort? Perhaps transform all multiple new lines into one single \n in one regex substitution beforehand ?

So with a few lines added to skip over the empty lines, best I can test this should fix the issues on your and hushcodens lines:

Edit: 8x24 ones tested to boot and uploaded

interesting, on the old version I get:

I assumed the Serial Number mess was just gobbledy gook, but now I'm not so sure?  :-\
