I will always suggest a ZyXEL VMG1312-B10A . . . but they are no longer manufactured and, thus, are becoming a "premium" second-hand product. Avoid the VMG1312-B10D, the "economy" replacement for the VMG1312-B10A.

Other members will, in due course, make suggestions of other ZyXEL devices for you to consider.

Another nail in the coffin for the VMG1312-B10D is that with the later versions of the firmware you can't use DSLstats!

Don't know if I was doing anything wrong, but the ZyXEL VMG1312-B10A was absolutely no faster than the HG612 it replaced.

I didn't even bother trying the VMG3925-B10B.

Not sure what to do now, may have two ZyXEL's I'd like to sell!

After having a think, I'm going to try the 1312-B10A on my father's line as his is a bit more unstable.

And, what I didn't consider, thinking about it - is actually using one of these on the AAISP line that I know I can tweak the MTU on and at least have full control that way.

Gave it a second go - it actually does add 1-2Mb on my AAISP line.

And this morning has cost me 4Mb of upstream on that line - These modems are no good for me, it seems.

I had worse upstream with the B10A on some lines compared with DLink DSL-320B-Z1 modems.

My experience is similar.  The B10A gives better downstream, but worse upstream.  It does also have a significantly lower bit swap rate than the HG612.

I have just installed a 1312-B10A and it has been a disappointment speed wise.  I have tried several modems routers on my ECI line, and the 1312 is actually the slowest.  I have had much more success with Lantiq chipsets.  Rough speeds have been:

1312 - 61 Mbps
HG612 - 62 Mbps
Draytek 2860n - 63 Mbps
Openreach ECI - 63 Mbps
Home Hub 5a - 64 Mbps
Draytek 2860n with SNR tweaked to 3 db - 74 Mbps.

Although tweaking the SNR does increase my error seconds, it's a price I'm willing to pay.  The Draytek is getting put back in ASAP :)

I would not be disappointed myself since the 1312-B10A is actually within a very small margin (~1.5% slower in your case) of another Broadcom-based modem that you have tested on your line. It could actually be faster or slower than the HG612 depending on line conditions and DSLAM parameters.

I imagine that this is at the target margin of 6 dB (3dB is not possible on ECI)? If the assumption is correct, then you may not benefit from having the 1312-B10A in place except for the potential for improved stability and lower error rates. It should be mentioned that if the 1312-B10A is in fact able to provide connection with less errors then it may allow for the DLM to reduce interleaving overheads leading to an increase in sync speed.

Quite obviously there appears to be a trend here. Lantiq-based modems seem to sync better on your line. Without seeing specific parameters then it is a little unscientific (since there could be varying levels of interleaving, etc.). But if the tweaking of SNR to 3dB with the 2860n shows itself to be stable and gives you the highest speed then I can't blame you for doing it.

Disappointed is perhaps too strong a word, but I was hoping the 1312 would be a decent improvement over the HG612.  Also, in the few days I've had the 1312, there's been no real decrease in in error seconds compared to the others, and I had high hopes for the "filter" the 1312 boasts.  It's no hardship going back to the Draytek though, and now I know not to worry about potentially missing out on performance, and I'm sure I'll get my cash back for the 1312 on ebay, so everyones a winner :)

1312 - 61 Mbps
HG612 - 62 Mbps

That's the first time I've seen anyone report the Zyxel VMG1312-B10A to be slower than the HG612.

You either have an exceptionally good performing HG612, an exceptionally bad performing 1312, or something in between.
Your experience certainly isn't the norm.

Definitely a VMG1312-B10A and not a VMG1312-B10D?

I tried my 1312-B10A on my father's line - he now gets 55000 sync up from 53000.

He's rather happy with that. Proves that not all lines are the same.

Just a shame he's on an ECI cabinet, attainable rose from 60000 to 65000
