Damn that keeps happening to me when I attach something. Iíll try again and actually check the size.

See attached, attempt II

That looks better, yes? How does one manage to get zero bytes?

Maybe the attachment gets deleted in my system (somehow, god knows how that might be?) before I hit [post], and it is only then that the file content gets uploaded to the kitz web server? I was assuming the file content gets uploaded early, uploaded when I choose the attachment.



I had to go back to the older version (autumn 2018) because otherwise I couldnít see the SNRM vs time graph. I call the new version, uploaded mid feb 2020-20-16, weaver-v06.

Yes, much better. To the second query: I'm not sure.

Ah, that may be the reason. If one specifies a file to attach to a reply, it is not committed until the reply is posted. So if the file is moved, zapped or lost in a passing black-hole before the reply is posted then the attachment will be of size zero bytes. The name is known but the content is null.

Agreed. I really donít know how the file might get zapped at my end before it has a chance to be uploaded. Thatís a question about how Safari etc works in iOS. Either that or a question about what on earth Weaver is doing. This zero bytes thing has happened half a dozen times with me. Of course itís my fault because I should check the size by reviewing the post after it has been posted.

No worries. One of us will eventually notice. But now you have two separate attachments of the same file . . . Perhaps I should delete one of them?

<Later> The attachment to the earlier post has now been removed.

And having that data, I could not resist the urge to generate the usual plots.

Good point. Perhaps delete my later post? I suddenly realised that since I could go back and edit the original post, I could perhaps change the attachment, so I did so, went back and attached it again and checked it afterwards.



I rebooted the server on the modem but I was still stuck in 1970 on the SNRM vs time graph and a reboot didnít fix the problem. I donít know where the state info is stored otherwise I could delete the state info and restart the server.

So it seems once the state is bad then youíre stuck with it, given my level of ignorance; I canít see that even reflashing it will reset the state to restore sanity?

Bug aside, itís a superb piece of software. Greatly impressed- thank you for all your work.



Off topic: half iOS question ; whatís the easiest way of me uploading one of my graphs as spring did there? I can of course do lots of screenshots and crop them, as I usually do. I would have to give all the bitmaps to my wife to make use of her expertise if I wanted a collage of them, tiled, as spring did back there.

I've done the simplest and detached the attachment to the initial post, on your behalf.

@spring - whatís the cause of the tone 154 [?] (150 < x < 160 somewhere anyway) QLN spike ? And the other two minor spikes?

I have identified candidate radio stations and have come up with dubious shaky candidate ideas for certain other types of activity for other spikes in my graphs.

QLN idk, but for SNR it's both interference and modem code tendency to do that. idk what else to say because i don't know how to solve such a thing. what version do you run? x6/V ?

lately i had interference too. no idea why but it's almost gone now.

I have several modems so Iím running both versions at the moment. X6 seems to be good.

yes x6 must be good. the exception would be if V turned to somehow be better which idk yet. or if x6 has some exceptions like x1 had. x1 ran better on some days but had days that were sometimes two or three-fold Forward Error corrections. i associate that with timeouts and stuff like that. it implies less stability in general.

only testing can know and it's still a personal result. i didn't really have a problem with x1 it's just that it performed slightly worse overall. [for non-vectoring lines like mine, that is]. i don't like x1 at all...

my dad also uses the internet so ill ask him and also see how games perform. i don't have anything new to add as i already know more or less how the SNR graphs will look and what error counts i would get. it's just that i didn't test to see what error counts V has during this time of external interferences. if only they were completely gone.

edit: x1 also had better bitswap, but sometimes sync'd with some bad bitswap and got stuck like that. that's why i need to re-sync x6 after 2 weeks and run it for another week. i think bitswap doesn't have a deeper meaning like SNR graphs. it's just what it is, unlike SNR graphs that can actually indicate whether or not there's something wrong with the modem code.

edit2: truth is, only long term experience of usage really counts in the end. not the error counts, SNR or bitswap graphs since those are ultimately meaningless. any modem code will always have ups, downs, and variations between different people.

edit3: i won't use dslstats again because it force restarts my 1312-b10a after a while, but johnson's stat graphs look a bit different than dslstats' graphs. that's why i can't just say "V's graphs looked better" even though i have old graphs.

edit4: any idea why dslstats did that to my device? the crash appeared to be random. did it ever crash your device? i prefer how dslstats graphs looked. more detailed and accurate than stats-server.

edit5: i'll use DSLStats before i restart the device since it has better graphs. that way i won't risk a crash. i also speed tested x6 and i can't imagine it working better. well i'm talking/thinking too much too soon

edit6: ISP is capped at 60mbit downstream. [i'll eventually call to update the package to 100mbit for free, maybe even next week. my line has 95mbit almost all the time. generic microfilters, no ferrites, generic 2(?) meter DSL cable. i used to have a better line with 110mbit but it was stolen... ISP gives 3mbit upstream for everyone]. if i connected the modem to the master socket i'd have no errors and 100mbit. but how can i pass cat6 through the walls of the house? stuck with using powerline adapters. i know, they emit unhealthy electromagnetic radiation.

external interferences are back, line lost sync at 4:00 AM and SNRM graph showed a dip in upstream.
guess i won't be able to run it for 1-2 weeks so i'll just switch back to V to compare.

edit3: first spikes in SNR for V: https://imgur.com/a/24F3NB1
doesn't look good at all. x6 must be better.. i think. maybe V stabilizes to be on par. we'll see.

edit4: no more spikes but the last tones still logically point downward. not linearly though. i think at this point it's safe to say only usage like browsing, gaming etc has any value. total SNR is ~9db for both. error stats still matter though.

edit5: error rates looking pretty good.

i'll post about the final results when i have them. i think enough information was posted by now.

edit6: it seems i do have DLM but it never reacts to any resyncs. only error counts and apparently the last 10 days had enough errors to limit my sync to 80. guess i do have some really smart DLM.

Re: ZyXEL Modems - eg VMG1312-B10A - Custom Firmware MTU 1508 Maintenance

So I'm not sure exactly why this is, or whether it is my imagination - but when using a VMG1312-B10A with the custom X6 firmware (I have vectoring on my line), the Internet feels less responsive. I've set the MTU at 1500 on my OpenWrt TP-LINK Archer C7 but still things just feel more sluggish.

I've plugged my Huawei HG612 back in and things are feeling normal again, what could be going on here?

X6 can glitch out sometimes. like X1 had the same tendency. that's why i decided to test it. i don't have DLM unless errors are so high they repeatedly [10+ times] drop the sync. i can test whatever i want with no consequences.

V is more stable. no doubt about it. i'm even seeing it in error counts. like i said:

i think resilient is the word to describe x6. i've been using the internet, gaming, and my dad as well. no complaints from him or me. downloads are stable. the best way to describe x6 is smoothness. for V it's more like "old fashioned cautions" that get through the hardest times. that's why x6 might not work for everyone. especially since (theoretically) it's a bit incompatible with dsl driver d26a. in practice i haven't seen that "incompatibility" manifest yet. [except maybe in SNR graph spikes... dunno yet]. it also bitswaps much better than x1 and even V. x6 is less conservatory than V. if that makes sense. so it's both more prone to errors but also better results. whether that potential is worth it i dunno yet.
it's not for everyone. X1 had the same problem. not for everyone.

maybe not even for me. i don't have the results yet.. all i know is i don't have vectoring so... might be useless for me to use X6.


edit: i misread you saying that you have vectoring as "non-vectoring". sorry. it then must be the incompatibility with dsl driver d26a.

i guess that one guy who said: "don't swap new modem code with old dsl driver" was right. actually, he said something similar to that.. not exactly that. but still.


i guess we do have results? don't try this at home.

lmao..

the Internet feels less responsive.
i've experienced that too. i thought it was my ISP... hah. guess it's not actually x6, it's the incompatibility with d26a.
maybe zyxel do other stuff before they just "change adsl-phy.bin". i don't know. i just know that,.. yes, the testing must be futile because it must be so simple.. so simple that the original modem code must be left in place for stability.




edit: if you compare X6:

to V


i think V does better in upload for example.
maybe that initial stutter with X6? idk. could be the ISP as i haven't tested it without the ISP. [i can do that though]
i'll switch to x6 in 2 weeks and see again if i have stutter etc because then i'll be sure it's not the ISP/line etc.

edit: don't mind the V having just 3.0 upload because my line has 5.0 upload. it's just the ISP ending up with 3.0. the graph is the only difference between the two.
