Upgraded my home fibre to Max/500 because why not, right. I have no use for Gigabit speeds, but it's so dam cheap. Only problem is my speedtests have been a little bit rubbish:

ISP is Devoli (who we use for wholesale at work), so testing to Devoli Auckland server (but other servers, like Spark's, yield similar results).

Connection is on VLAN10 using PPPoE.

All tests done on the Windows 10 app, gigabit connection etc.

Upload seems fine, but that download just won't go up! My immediate thought was the router couldn't hack it, but during this test the CPU doesn't get close to topping out, sitting at around 30%.

So with our wholesale account, we get some access to the Chorus testing tools:

So I thought I would ask on here, before I go to support and ask the same question, what's the deal there? Does "transmission errors" according to this tool equate to packet loss? I would of thought if there was packet loss happening it would impact lots of other things, but all "normal" stuff works fine - just can't hit that sweet 900Mbps on speedtest!!

The RB750 is doing the VLAN in software on the CPU, and PPPoE is pretty intensive - I suspect the combination is that the router is getting slapped when you're testing. Are you able to login and watch the CPU load when you run a test? I suspect it'll be getting pegged.
If you can eliminate the VLAN, that'd certainly help things, and if you can do IPoE, even better.

Anything I say is the ramblings of an ill informed, opinionated so-and-so, and not representative of any of my past, present or future employers, and is also probably best disregarded.

Could be a speedtest/browser issue, have you tried another download source like an Ubuntu iso torrent or steam download?

As above, CPU doesn't get above 30%.

Surprising - are you running your speedtests through the native app or web browser? Could make a difference. The ONT stuff from Devoli is pretty abstracted from useful information - I'm sure they have documentation that can advise you what "reduced" actually means, so it might pay to touch base with them.

I did wonder if we were getting the dumbed down version of the ONT information. "Reduced" seemed a fairly arbitrary way to describe something.

All tests are on the windows 10 native app - no difference in a web browser FWIW.

Yea might just flick it through to Devoli and see what they say. Don't really care that much to be honest, just thought it would be fun.

Do you have another router you can try anyway?

Amazing router - i've installed a few of these and they are rock sold.

Have you got a 10g handover? I remember when I was swapped over to 2d gig plan and couldn't get above 300mbps download until the local handover was upgraded

Yea I have a 3011 on it's way down from Snappernet as I wanted to rack mount the router anyway (#vanity) so will see what difference that makes.

Is it still worth doing the old PPPoE dialler directly on the PC? Thought I would give that a shot in the weekend.

Only if you're gonna spin up Linux to do it, the Windows one is pretty naff.
The 3011 should perform significantly better than the 750gr3, might make a difference.

Can you do another refresh on the ONT status? Where in NZ are you as I know we were having issues with a few ONT's flapping about and giving the same results in auckland.

That picture you posted on the ONT is saying a lot just by looking at it! You should see something like this.

I have had that exact same router do between 700-800mbit with PPPoE but Untagged.

To me, I think there is something wrong with the ONT with that picture that you have posted.

Doubtful, the 880mhz dual core processor is much more powerful than an edgerouter lite, which in turn, is more than capable of routing gigabit and both also have hardware acceleration built in.

We had a client with a RB2011 hitting 100% CPU usage - the 750gr3 doesn't get above 3% and they hammer it - over 4tb a month and sometimes over 300 clients connected

I really don't think it's your router

The 750 should be capable. I haven't got another one on a gigabit connection to test (only have 3011's at business customers premises) but remember @michaelmurfy quoting the 750 could do 800Mbps-ish on PPPoE, but that was some time ago.

The 3011 with ARM processor is just that cut above. It's performance on IPsec is fantastic for site-to-site transfers - easily fully utilising 100Mbps.

I was swapping it anyway, but as I don't see the CPU getting pegged on the 750 anyway, I don't think putting a 3011 in will make a difference either.

Yep realise what it should look like, which is why I thought, yep might have a problem there.

I'm in Palmerston North. And yea, some anecdotal evidence suggests 800Mbps should be achievable.

I might try shifting the VLAN tagging to a separate switch just to see. Again though, the CPU isn't getting pegged, so I don't think it's a resource issue.

That ONT looks like its been flapping about since the 6th.

I think you need to start a ticket and email provisioning@devoli.com and email them a pic of that screenshot, the ONT serial number (the serial number from the Vumeda Portal not the serial number on the ONT as that is wrong) and the ASID.

Has the order been completed on the service orders page? or is it still in Billing?

I think that your problem is there in the ONT or the OLT, or it may have been provisioned wrong.

If you are going to Drop the VLAN tag it will cost you 1 months service fee on the connection (not the Data), and can take some time as it will be a full reprovision of that circuit.

The upgrade was done on the 6th which is why the history only starts there I assume.

Yea flicked a message through to Devoli this afternoon, so will see what they say.

Na I won't re-provision the circuit, just do the tagging on a separate device just as a point of isolating it.
