Nothing wrong with your FTTP connection - its 100% your kit (router)

Anyhow. see how the FW update /factory reset goes.

So there is progress. The results after the reset and firmware reload can be seen from 7pm last night. This morning I remembered I had an EdgerouterX in a drawer that I had tried to use but was too complicated for a simpleton like me. Firing it up and connecting the BT line gave me the following results, with the ERX results starting at 11.30am.

So yes, 100% it's the Draytek, but the question is why and what am I doing to make it perform so badly IF they arent throttling ICMP. As I think I said, you can use the QoS functionality to set ICMP to Class1, which I tried with no difference. I have also excluded it from being a cable issue given the results on my laptop and the ERX.

I will ask again on the Draytek forum and post anything interesting here.

I see no evidence that the Draytek is "performing badly".

What you see is that when the line is idle, 1 in 100 ping responses is being delayed by ~200ms. This is quite possibly because the router has gone into some power-saving mode due to lack of anything interesting to do.

Unless you have evidence that it's actually impacting your use of the Internet, then just ignore it.

Permit me to rephrase. I am interested in understand why the Draytek is reporting latency in the way it is.

What does bother me is that I am only getting ca. 300Mb/s even when connected directly to the router or even directly to my laptop via PPPOE, but that's off topic and something I can work on with BT with the HH connected.

That generally tends to point to an issue with the laptop - either the NIC/adapter is not up to snuff or there is something in the OS/AV/software stack that's holding things back. 500 Mbps should be easily achievable up and down (I know you have an asymmetric service) on a relatively modern machine.

Fair enough: that's probably one to take up with Draytek support, given that you now have plenty of evidence to support your observations.

Indeed; however that could limitations of your end client device under the load of a browser-based speedtest. Trying a different client device, and/or booting your device from an Ubuntu Live USB stick, will help to rule that in our out.

This is relatively recent, I have had reliable 500+ when directly connected to this machine in the not too distant past.

Sounds slightly odd. Typically you shouldn’t see that sort of variation in headline speed on a capable setup.

If it’s a windows box, some third party and VPN software can fudge up the networking stack and cause these sorts of issues.

What's your Firewall Syslog showing?

I've had a quick look to see if anyone else has monitoring, who has a Draytek, however I can't find anything.
I'm trying to see if this is expected behaviour or if something else is going on.

"What's your Firewall Syslog showing?"

There's nothing in the syslog originating from the firewall per the "Firewall" filter.
