I have noticed the new Vigor 166 appears to be on sale in the UK. It is only the Gen1 (so up to 330Mbps) but presumably is a lot better on the inside than the 130.

Is it Openreach approved?

I have not read anything definitive but it is being advertised as such https://draytek.co.uk/products/business/vigor-166#overview. I read the delay on it going on general sale was because it lacked the Openreach approval, but as it is now on sale I guess that means it is?

I believe a specific UK part was rolled out in December - V166-K - difference seems to be the preloaded firmware which is preset to work with Openreach G.Fast settings.

Nice, I'd probably pick one up if I weren't moving to a VM area.

It's incredible how Draytek have survived for so long as a company without employing a product designer

Well. I have tried it on mine. No change yet.

I can only get 1/2 sync upload. Can anyone help me debug? I apply the 101 tag within the VDSL settings, (rather than on my Velop mesh router) - I think I am using the same settings as https://imgur.com/gallery/Xykm7Cf

Is there any way to edit the Cur SNR Margin to 3 DB?

Firmware isn't great on the Vigor 166, a bit buggy to say the least

Alan Small · 26 Feb 2021 at 13:11

Yep, it's a mess at the moment.
Lots of reports of low sync speeds, particularly on VDSL lines.
The stats readouts are mostly dead (reading 0) making it hard to figure out problems.
Many of the CLI commands don't work (including SNR to tweak the target noise figure, it crashes the unit)
A new version, recently released in the EU & identified as GEN2, also suffers from the same problems (same firmware 4.1.1)

I can no longer lower my snr margin with my Draytek 130. I’m on plusnet. It used to work. Anyone know why it now doesn’t?

Why not, do you get an error message?

Works fine for me on plusnet

no idea what said:

It says it’s updated successfully and reboots but it stays the same. It’s currently at 5db but I had it down to 2db before.

It's only a target and not a hard setting AFAIK, it'll take a while to settle down too.

It would apply instantly before.

Thank you @ChrisD. had the modem set up yesterday and applied vdsl snr -30 and it has been stable with no increasing error counts but yesterday's actual rate was at 64Mbps but has now dropped to 56Mbps, do you know if it will increase in time?
