UDM Pro on ATT 2gig Hyper BGW320 and Microtik SFP adapters

Thanks to everyone who’s posted before… I’ve successfully configured my UDMP and BGW320 and am seeing 2.3Gbps down and up on the UDMP dashboard - sweet! This is with AT&T Hypergig 2G service. Unfortunately, none of my wired devices are seeing more than 330 Mbps though, whether GigE wired or multi-gig. I’ll leave all the wireless devices out of this discussion for now.

How do I make sure I’m getting the expected Internet performance on my GigE wired, 2.5G wired and GigE wired APs?

Here’s my config

  • UDMP connected to the 5gig port on the BGW320 using a Microtik S+RJ10 on the WAN SFP+ port
  • UDMP lower SFP+ and Pro 24 PoE switch upper SFP+ connected, 10Gbps enabled
  • Pro 24 PoE lower SFP+ has a Microtik S+RJ10 on it as well
  • MacBook Pro has a Plugable 2.5G usb-c adapter connected to the lower SFP+ w/Microtik port on the switch.
  • BGW320 configured for passthrough to UDMP via drop-down in the config menu, firewall disabled, WAN IP is showing up in the UDMP

Observations

  • the UDMP is seeing 2.3 Gbps up and down right now per the console dashboard as stated above
  • if I switch the MacBook Pro to one of the 1 GigE ports on the BGW320 I see a throughput of 917 Mbps down and 787 Mbps up. I get about ONE THIRD of that connecting to the lower SFP+ / Microtik port on the Pro24 PoE. I’m using AT&T’s Internet Speed Test page, https://www.att.com/support/speedtest/

UPDATE:

  1. when connected to the SFP+ Microtik LAN port the ookla speed test app shows 1500+ Mbps down / 1600 Mbps up to AT&T Tucker GA.
  2. when the same laptop is connected to a GigE port the result is 941 Mbps down and up. So clearly the 2.5G connection is working.
  3. So other than the anomalous results for the att.com speedtest page, there doesn’t seem to be an issue here after all

I tried enabling Jumbo Frames and Flow Control per Mike Swanson’s blog post, but I’m not seeing any improvement

Here’s a screenshot of what I was seeing. Note the UniFi dashboard speed test results and the performance shown from the AT&T Internet speed test page:

What testing is being done on the client side? Not familiar with the UI but a ping of 13ms is high for fiber and might be a fault of the server used for testing.

I’d just try a regular speedtest.net test and see what that gets you.

For reference, I had AT&T 2 and 5Gb w/ a UDMP and never had any issues (I’ve since moved off of UI routing).

I also have AT&T’s 2 gig service running through a DMP, using the MikroTik SFP+ adapter for the WAN side. The only difference on mine is that I’m using official Ubiquiti SPF+ fiber modules to uplink to my Enterprise 24 PoE switch, and have no issues downstream. All clients get 1 gig or 2.5 gig. No need for jumbo frames or flow control.

If you connect to one of the gig ports directly on the DMP do you see gigabit speed tests on your MacBook? If not, then there is some configuration issue on your DMP. If not, then I’d verify the SFP modules between the DMP and switch.

Following - looking to have an almost identical setup on ATT 2g.

Hi, this may be a dumb question, but which port are you using from your ATT modem into your Pro?

the client testing right now is just hitting the att Speedtest site via a web browser on a MacBook Pro with a Plugable 2.5G usb-c ethernet adapter.

I just tried the regular Speedtest.net site again per your suggestion. Holy moly. I have no explanation for this. 1.3 Mbps down, 1.4 Mbps up. I’m on the microtek SFP+ LAN connection.

good call… 861 down / 609 up on a DMP gigE port.

awesome… I have a DMP SE coming tomorrow in case this doesn’t sort out. only using the Network app right now, but we’ll see.

Unless they’ve started using different hardware for hypergig now, it should look something like this

You’d want the blue “5Gb” port to go out to UDMP/SE
The yellow ports are 1Gb only, and the red ONT port is mostly not used by ATT on these

Try the Atlanta GA NetProtect server, that usually is pretty reliable for a good fast connection.

But 1400/1400 is a good improvement, so I’m betting at this point it’s your client, not really the ISP connection. Or it could just be a busy time in your area.

…and 868 down / 553 up on a PoE 24 gigE port. so the SFP+/microtek port on the switch is actually slower.

That’s right. On my BGW320 the correct port on it for multi-gig WAN in to the customer router is clearly labeled “5Gb”. The SFP port on the BGW is the incoming fiber connection

600 down, 1600 up to net protect.
1600 down and up to AT&T Tucker GA.

the AT&T Speedtest page does not show anywhere near these numbers… so seems like all’s well?

switch reboot didn’t change anything. right now my microtik SFP+ LAN port just sucks. The microtik on the WAN side works fine.

Ok great, and just double checking, I use a cat6 cable from the blue 5G port into the SFP port right?

It’s fine. There’s tons of variables that can affect speedtests, it’s completely expected one might be good while one might be trash. I’d say just use everything and know it’s working as it ideally should, if you notice any abnormal slowness or complete disconnects, then you can take a look at it.

Those still seem like slow speeds for a hardwired device on fiber - are you testing with something like speedtest.net using one of AT&T’s regional servers? A client test hardwired for me is mid 900s both directions, and connecting to a 2.5 Gbps port using a USB-C to Ethernet adapter I see 2100+ up and down.

Are smart queues are disabled under your WAN settings?

Yes, where for my UDMP it’s the SFP+ WAN port (labeled 10 on the dashboard pic) on the top right, equipped with the Microtik transceiver . On a DMP SE there’s a 2.5G Ethernet WAN in that works too

thanks for the sage advice :-)the ookla desktop app appears to be smoking something.1525 down/1690 up to AT&T Tucker GA https://www.speedtest.net/my-result/d/532044296

Per ookla, the app is more accurate due to other processing in a browser (extensions etc.)
