Good spot Hushcoden, but I am currently at 1.4db ds and 79999 sync so probably not worth the reboot as I will lose about 5mbits. Still have downloaded the 16 firmware ready to install.

I got a very slight speed reduction with the .7 release - d/s sync 2858 -> 2847 but I did not leave it switched off for 30 mins which I should perhaps have done and this could just be DLM randomness.

I'll try the jumbo frame firmware with original modem code again and see if it does better than the modified with latest version x1, that I've been on for 3 weeks [there's x3, but it's a fix for Intel CO's with FW version 12.3.8 in G993.2]. I have to do this instead of comparing with previous stats as it was fine for the first week then it got worse, could just be my line.

Edit: So far the error rates in 4 hours with original aka v, are as much as 7 days with x1. Going to go back. There is higher SNR, but too many errors. Also dropped my WAN connection after 4 hours (?).

Edit2: Seems to have sorted itself & is perfectly fine now. I'll leave it for a few days to be conclusive.

Thats valuable information spring, thanks for trying it out.

So are you saying after trying the v version you went back to the x1, or did the v version sort itself out?

Yeah the ZyXEL AAJZ.14 with just jumbo frames, by you [original adsl_phy.bin] is doing alright for this hour.

Before I changed firmware I did "adsl connection --down" & after uploading let it restart into a sync. Maybe due to not waiting [the line fit the mold of x1 after 3 weeks, and took a few hours for v to stabilize. plausible].

Edit: First time this happend, the modem rebooted itself; but the jumbo-frame FW I've used before was of Olipro. I'm going to flash to Olipro's. That is, assuming it's not my configuration file made for jumbo+3925 that I also use on the jumbo-only. I rule out electricity because it didn't come on and off, rather a lengthy reboot. To clarify, I used re-opened DSLStats a lot today so it might be this modem, too, has reboot issues. But I'm doing this to verify. Other than that v is running just fine, need more time & another switch back to x1 to know if it's better or worse. Right now things are better but time is needed to draw relations.

Edit2: Towards the end of the tones v has a better looking SNR graph than x1, but up until mid tones x1 is better. Also, notice the drop with v in multiple spots at tone 800. So, I rather not evaluate which is better. I plan switching to x1 again to confirm.

Edit3: I think I'll leave it on v, for some reason there are fewer errors & unless there is an increase I'll remain on it. Before that v didn't do as good as now [as good as x1 did], and x1 also did better than v in the first week after switching to it, before gradually getting worse. Absolutely no idea why it's like this. But when x1 worked well, like in its first week or two, it did better than the prime of v. I'll use v for another couple of days, and decide if to try x1 again.

Thank you for the detailed info spring.

Those graphs make me sad though, does the ISP in your area have a monopoly? Its criminal that you are capped like that given the attainable.

Seems v has been fixing itself.  :D

Note up until now, I have just a generic dsl cable & generic microfilters, no ferrites, so not the ideal setup but I don't think it matters.

I think I've learned enough to say that because switching modem code can lead to endless adjustments to the line, the more time it's tested, the more is known about it. first day I experienced one disconnection & higher than normal errors in the first 4 hours - then up until second day many SNR graph changes & normal errors, third day started to look exactly how it did in my previous use of it. so i'd say 3 days [of course, if it's performing badly as soon as a sync & on the 2nd day as well, it's not going to improve. if someone has DLM, the first day or 12 hours should be the deadline as according to my experience only the first 4 hours were the "transition period"]. it may require one manual resync if it performed better for the first week then had a decline, for confirmation [should be at least as stable as the previous modem code].

Also note this is on VDSL and not ADSL [can be vastly different].

Edit: Olipro's loads pages much faster, I don't know if it's related to using it, but it does.

Edit2: Drops at tone 800 with v came back, but this likely means x1's big and only problems at the last few tones weren't a coincidence either.

Edit3: I think v had enough time and is indeed doing better than x1 but I'm flashing back to x1 to confirm.

Edit4: Alright so first off, it wasn't Olipro's being faster; Johnson's is just as fast. Second, x1 exhibits its classic graph: https://i.imgur.com/msesn2P.png . I will manually open DSLStats to snapshot every 12 hours to follow up.

HLog/QLN are calculated at sync, and the previous sync was of V not x1

I don't recommend x1 at all (for someone with DLM, if not then sure have fun with probably the same results I'm getting) I'm just doing this for testing xd

Upstream bitloading is the same, missing much, and you can compare it with V, however I'm sure the next time I sync it would be fixed; at least, first time I've noticed x1 to sync with missing bits.

Edit: I think the thing is now, if it can run a month stable [v ran stable "forever"], if it can't I'll flag it as not worth anyone's time xD
It's capable of performing better than V [at least on par] but the problem was the small gain on the good days wasn't worth the devastating days. 50 FEC on DS/US per day is V. x1's best is 30.

Thanks for the reminder j0hn, link was in my spam folder.

So here are 2 builds from the latest AAJZ.16 version for the VMG1312-B10A, the differences to last version are minor so no real need to upgrade if you dont feel like it. Just a version with the jumbo frames patches and another with the old telnetd binary if you enjoy having more than one telnet session open at a time, no updated dsl_phy as it seemed it only benefited me and caused more confusion than good.

Both tested to boot, but not on a line yet.

I have not put in a request yet for the 8924/8324 version, but the 1312 one took a while after the release so it will probably be similar.

Edit: request submitted, will get back as soon as I have the new source
