Have you tried the recovery method: https://www.draytek.co.uk/support/guides/kb-firmwarerecovery-drayos

Tried the GUI and the TFTP method. 

Being a Mac user I had to breakout the emergency windows machine for the TFTP thing.  A nice reminder why I don't like Windows.

Draytek support asked me for a screenshot earlier today so will see where that takes us.

Just picked up one of these modems - using it in bridge mode it works flawlessly but I can't access its management GUI via its IP on P2 unless I unplug the router going into P1.

Is this normal?

I was hoping to monitor line stats via SNMP through P2 but not sure why when P2 is active P1 can't be pinged and vice versa.

Leonroy, it worked fine for me but I did change the ip of P2 to match the subnet of router.

Great that it works for you. I ended up returning mine as I couldn't get it to work correctly. What kind of connection are you using it for (VDSL or G.Fast)? And do you know what your cabinet type is (Huawei or  ECI)? Curious if it was something specific to my unit

Using G.Fast, believe it's Huawei. Previously was using VDSL - swapped between the ECI and Huawei modems - zero difference that I noticed but I was getting pretty much 76/20. What was the issue you had with yours?

I don't see what the point of port 2 is since plugging into it seems to mess with port 1. I managed to log onto the Draytek eventually using pfSense to create an Outbound NAT route on a second WAN interface IP as per here.

Also managed to enable SNMP using this command via the CLI:

mngt snmp -e 1
mngt snmp -g supersecretread -s supersecretwrite

So now can get some snazzy graphs showing noise levels and negotiated rates.  ;D

Sadly I returned mine too. Support were great but the beta firmware did not solve to constant latency. I could see it on thinkbroadband monitor and PingPlotter showed constant spikes and packet loss.
Tried it with 3 routers too. Voice coms on playstation had a constant blip.
Stuck the old HG612 and it’s back to a smooth line. Hopefully at some point they will improve it but once support ran out of ideas it’s time to call it the day.

After two weeks my connection has gone from a stable 69Mbps on the Vigor 133 down to 52Mbps on the Vigor 166, as far as I can see I'm not getting any errors on the line and uptime on the physical connection is 194hrs.  Stats are below;

Mine wouldn't hold a connection for any more than 10 mins before disconnecting/reconnecting. Seems it didnt like vdsl connections with Huawei cabs, and no G.Fast in my area. HG612 been solid now for 3 weeks. My concern and why I got the draytek is if the modem breaks I have no backup. Perhaps I should try the 133 since I don't need G.Fast...

as far as I can see I'm not getting any errors on the line

The error counters are broken and always show 0 errors.

Your high attainable/high SNRM and low sync is rather odd though. It suggests the modem is capable of syncing much higher and it doesn't look like DLM has banded/capped the sync.

I recommend resyncing the line and seeing if the sync increases. In theory it should.

By resync, do you just mean turn the modem off/on, or do I need to leave it off for 30mins plus to reset?

Either, but its generally safer to do the 30 minutes.

Thanks for the reply, I left it off for 40mins or so, turned it back on and no change in the initial sync I'll recheck in the morning.

Just thought that I'd mention that I've been running my 166 as a modem on a G.Fast line without major problems so far.
However when I turned on Hardware Acceleration (just to see what would happen) the connection became very unstable.
So Draytek have lots of problems to fix, although VDSL customers seem to be having more problems that G.Fast ones.
If anyone gets a link from Draytek to new BETA Firmware it would be nice if they could post it here.

Have you already tested the 423RC1? https://forum.kitz.co.uk/index.php/topic,25203.msg429392.html#msg429392

I tried the Latest release candidate R23RC2 and that was more stable but still no increase in throughput, I put my old 2016 build ECI modem back on and my latency (QoS is off on the router) went from 200-300ms UL on the Draytec to 30ms on the ECI, download is about the same at 38ms Idle at 18ms and on TBB and I get a B down and b Up or a A down and B up on bufferbloat compared with A and F with the Draytec, with spikes up to 314ms and sometimes erroneous downloads of 1GB peaks which would be a miracle.

 The new beta firmware gives some of the stats now but still no errors but does show the cab you are on, I am on a ECI. After a month of this modem I have decided to return the 166 (I have a week) its just not worth the effort to keep playing with it and watch my downloads actually become corrupt due to packet loss I imagine. Also I won't buy a Vigor 130 as I believe its the same chipset as in the last ECI v2 Openreach modems anyway and they run just fine on my cab.

 My ECI modem runs cooler, syncs better and even though I am still interleaved I did gain back 3 Mbps straight away, so hopefully I will get the whole 10Mbps back in about a week or so. The 166 needs alot more work and I don't have the inclination to keep playing with it and messing my line up at this time.

Here is the link if anyone wants to try, I guess newer isn't always better, I think the 166 is a victim of the pandemic and issues with firmware and hardware and maybe Intel owning it now. Moreover it seems to really work for G.fast but not so well for VDSL, and my ECI modem is fine and I have a few spares for now. A lot of money paid for a device that wrecked my line gets very warm and as does the PSU compared with the ECI modem that gives off hardly any heat in comparison and the PSU is cold to the touch, and also less errors it appears and no packet loss. A shame but I dont want to be a beta tester at this price range, even though we all are with new tech really.

Thanks for the link to RC2 beta.
I didn't bother with RC1 as others has already reported that it didn't change anything.
However, I'll give this one a try & see what happens on a G.Fast line.
