On Monday I switched over from MyRepublic after reading these forums and having some of my own bad experiences (1-2% constant packet loss at peak times, recent dropouts) but since the switch from MyRepublic I have not been able to get the speeds I had been hoping for and I have been getting intermittent packet loss for around an hour for the past few nights using 2d (5-6PM, 9-10PM). I was able to get 950d/550u on MyRepublic but I can only get around 700d/450u now. I have not changed anything in my network, I just entered the PPPoE details and it was working. I have a UDM-Pro and I am using Ethernet to the UDM-Pro directly.

I did not have packet loss to this extent on MyRepublic and speeds were fine.

Things I have tried:

- Turning off IPS/IDS. No success

- Testing multiple computers

- Restarting everything

- Using bootable ubuntu USB (same speeds within error)

This is valorant for example. I was playing with a friend at the time (who is currently on MyRepublic) who had the 1-2% packet loss that I used to get but not to the extent I was.

So I hate to say it but the speeds you are getting are expected over PPPoE with a UDM Pro. MyRepublic uses DHCP and the UDM Pro has no issues with full throughput but the UDM Pro does have issues with PPPoE connections and you will see mention in the latest firmware. Not only the latest but firmware going back for a long while now.

You will typically see ~ 700-750 if not less with IPS/IDS enabled.

One of the reasons I actually switched away from 2degrees to an ISP with DHCP. Its not a 2degrees issue but simply due to the fact that its using a PPPoE connection.

I tested a UDM (non-Pro) for about a week and this matches what I was observing. I expected the Pro version to be able to handle gigabit traffic with no issues... 😳

I did manage to get a speed boost on the UDM by increasing the MTU in the WAN interface, changing the pppd MTU to 1500bytes, and disabling the TCP MSS mangling rules. Had to do it every time there was a configuration change though, so I ended up migrating to OPNsense...

Ah thank you. I should have done more research. Hopefully, this will be fixed in future iterations of the firmware. Any idea on the packet loss situation or am I better off trying to call them? Queue times seem very long and I have not yet got through to someone on the phone.

Edit: It also explains when doing a speed test from the UI dashboard the speeds were better, must be avoiding the IPS/IDS. I have since disabled IPS/IDS and DPI and speeds are better.

On 2degrees best get the supported router, a Fritzbox. 2degrees has been very reliable for me for years, currently have a Fritzbox 7590.

There is still plenty of hardware out there that is incapable of routing 1Gbps well - with price being no indicator of performance. The reality is a $10 2nd hand Huawei HG659 can still perform better than some off the shelf $500 "gaming routers".

Or a $100 Mikrotik that will give you better routing features. As opposed to a Unifi Nightmare machine that just generates a bunch of pretty graphics.

Have to agree, the UniFi routing feature set is blllaaahhh as seems the performance, as said a MT Hex will do it for $100, bargin.

It's not so much that it's done in software, but how well it does it. Mikrotik also handles PPPoE in software, but it's how much of the rest can be offloaded. MT can use Fasttrack to keep the load off the processor for some firewall stuff, or in the case of multi core hardware, better thread handling. Having the UDM doing DPI will consume considerable processor resource, reducing max throughput.

Whether they solve this remains to be seen... or their solution might be the SE model...

PPPoE is most common throughout the world it seems. I can't imagine they'll let this one go without doing something about it, especially on a router like that.

I'm not too worried about it, disabling IPS/IDS and DPI has improved the speeds for me (now within 90%) so I'll hold onto the UDM-Pro for now. Hopefully, Ubiquiti sorts this stuff out or it may just be the last router and switch I'll touch from them.

Pppoe might be the most common ISP interface, but few US ISP's offer GigE services, we are very fortunate to have fibre as we do here.

Based on my experience with UniFi, and I have onsold thousands of dollars of it, don't hold you breath

There are also several other devices and brands that have issues with PPPoE - experienced similar issues for years trying to use my Netgear Orbi’s to route full gig. Had to end up using the ISP router and Orbi’s as AP’s behind this.

ISP provided routers are tried and tested for throughout and while lots of devices out in the market claim wonderful and fancy features - many fall short to route full gig over PPPoE.

The Ubiquiti USG which is their cheapest console and you can pickup on TradeMe for ~100$ can route full gig.

Ubiquiti make mass market hardware targeting price points in the market. Their history of buggy hardware and software is one of the reasons why many people would never consider the hardware an option for deployments.

In the wireless space they've pretty much scored an own goal because it's forced true enterprise vendors (Aruba, Ruckus, Cisco etc) to now offer products that are far superior but at price points that are now very similar.

I would not just assume things would be fixed - and there are also some significant limitations that quite a few vendors have found with hardware based acceleration on some common chipsets causing instability.

Looks like they may have solved the PPPoE slowness on the UDM/Pro!
