Default Vigor 2860 firmware versions

I have a Vigor V2860 which I use on a VDSL service.

The currently recommended firmware is v2860_3894_BT, but this drops the
line about 3 times per day, at random. The FTTC cabinet is almost
exactly a kilometre away, and the router reports download speed at
28Mbits/sec, 3dB SNR margin, and 27dB attenuation; which is consistent
with the kilometer distance. The SNR margin varies between 4dB and 0dB,
and when it is near 0dB the connection is likely to drop. When it
re-syncs it achieves 3dB and virtually the same downstream speed as
previously.

By contrast a Technicolor TG588v v2 router supplied by my ISP keeps the
line up much better - the longest I tested it for was 7 days during
which it stayed up for the whole week with no breaks.

Draytek offer several different firmware options, as follows:

v2860_3894_vector1 567517 562301 . Vector
v2860_3894_vector2 574307 571801 G.INP Vector
v2860_3894_vector4 579F17 573F01 G.INP Vector
v2860_3894_nonvector 548006 544401 . .

.... but I have not been able to find any document that explains the
differences between these versions, and therefore which I should use on
this rather long line. As noted above, some options provide both
vectoring and G.INP, but there's no other information.

Can anybody here help, please?

TIA

I'm using 3.8.4.3, which is late 2016 I think.

I am on a 1.2km line, and do not get drops.

You can adjust the Vigor SNR delta to reduce your maximum speed and achieve
more stability, or vice versa. Has to be done from a command line prompt, if
you get it wrong change it back.

Thanks Angus. I've tried to find the telnet manual for the V2860,
without success. The Draytek site only has older manuals which suggest
adsl codinggain (for 2800 series)) but nothing newer. Can you suggest a
link please?

I tried "vdsl snr ?" and this appears to be a valid command. I'm
currently testing the v2860_3894_vector1 firmware and this has kept the
line up for 48 hours compared with the 2 to 10 hour range seen with the
v2860_3894_BT firmware, so I will not try anything else yet for another
few days.

Curiously with the vector1 firmware download speed is marginally higher
at 28,844 rather than 28,311 kbits/sec and the SNR value is 3dB rising
overnight to 5dB compared with 3dB dropping to 0dB (usually followed by
a re-sync) for the v2860_3894_BT firmware. Hence my request for a
detailed description of the different firmware versions.

Thanks again.

That's the same as in v2860_3894_BT, which was very unreliable for me.
Currently testing v2860_3894_vector1 567517 562301 which for two days
has been 100% reliable, so far!

It just goes to show that everyone has different issues! I guess it
depends on what the line actually does.

When built, this house was the only one in teh road, so all the services
come from a long way away. Both immediate neighbours have higher sync
speeds because they are only about 0.3km from their cab, and we are 1.2km.

I thought routers were supposed to do this dynamically. BT ones do [rather slowly] in response to weather effects on one's physical connection.

Some allow you to offset the target margin and lie to the kit in the
cabinet, to favour speed or reliability, I've used it on Cisco 877 routers.

As you've probably already discovered, but for the benefit of others,
the home page for that model is:
https://www.draytek.co.uk/products/business/vigor-2860

The currently recommended firmware is v2860_3894_BT, but this drops the
line about 3 times per day, at random.* The* FTTC cabinet is almost
exactly a kilometre away, and the router reports download speed at
28Mbits/sec, 3dB SNR margin, and 27dB attenuation; which is consistent
with the kilometer distance.* The SNR margin varies between 4dB and 0dB,
and when it is near 0dB the connection is likely to drop.* When it
re-syncs it achieves 3dB and virtually the same downstream speed as
previously.

By contrast a Technicolor TG588v v2 router supplied by my ISP keeps the
line up much better - the longest I tested it for was 7 days during
which it stayed up for the whole week with no breaks.

Draytek offer several different firmware options, as follows:

v2860_3894_vector1*** 567517 562301*** .*** Vector
v2860_3894_vector2*** 574307 571801*** G.INP*** Vector
v2860_3894_vector4*** 579F17 573F01*** G.INP*** Vector
v2860_3894_nonvector* 548006 544401*** .*** .


As you appear to have discovered, the downloads page for that model is*:
https://www.draytek.co.uk/support/downloads/vigor-2860

* As an aside, since telnet commands have been discussed downthread,
note also on that page the User Guide download (PDF), which has an
appendix of telnet commands from p561 (printed) p575 (PDF reader) onwards.

Returning to firmware, if you click on the Release Notes on that page
and download and read the resulting PDF, p2:

"Modem Codes

There are six firmware variants available for download.
Download Filename Firmware Filename Modem Code G.INP Vector
VDSL ADSL
v2860_3894_vector1.zip v2860_3894_567517.all 567517 562301 Y
v2860_3894_vector2.zip v2860_3894_574307.all 574307 571801 Y Y
v2860_3894_vector4.zip v2860_3894_579F17.all 579F17 573F01 Y Y
v2860_3894_nonvector.zip v2860_3894_548006.all 548006 544401
v2860_3894_BT.zip v2860_3894BT_576D17.all 576D17 572801 Y Y

We recommend using firmware "v2860_3894BT_576D17.all" unless you have
specific line issues.

G.INP: G.998.4 TX and RX retransmission support
Vector: G.993.5 Vectoring support. If your line does not support
vectoring then the modem code will operate without."

So I agree that there's nothing there about the others, but they do seem
reasonably confident that you should be using the BT version, which
makes sense, given that we're in the UK.

However, if you'd like to explore the others further, or perhaps more
usefully receive help specifically targetted at your problem, then I'd
suggest raising a support call, and tell them what you've told us:
https://www.draytek.co.uk/support/techquery

I've had reasons to do this twice now, and both times have had helpful
responses.

As another aside, my DrayTek Vigor 2830 regularly used to drop
connections via 4G Huawei E3372s USB stick, and the only sure way to
reconnect was to power down the router (rebooting didn't usually work).
Then, as previously documented here, its WiFi died, so I hacked a BT
Home Hub 5a router and plugged the Huawei into that. It seemed to work
fine for a while like that, but now the HH5a too is dropping the
connection, and requiring rebooting or power cycling to get it back!
Infuriating, but that's another story, and perhaps another thread.
