ADMZ HH4000/Giga Hub Latency

[DPS1]

Hi All - I've posted a few times about this over the past year plus. I've tried ADMZ on several HH firmwares and just tried again on the latest (1.9x). I'm using a UNIFI Next Gen Firewall which displays latency. Within minutes of rebooting the HH and the UNIFI router, i receive a public IP and all working. But as you can see from the image i attached, i start immediately to get up to 70ms of latency. I switched back toa  double NAT and the latency disappears which you will see in the image. And yes ive tried PPOE with several routers including a XEON based Pfsense and i just cant get much bandwidth (1.4 down and 300 up). ON ADMZ i get 7.5Gigs up and down and same on the double NAT. Bottom line the firmware still isn't working well.

Still painful latency here.

I’ve honestly had the same issue since August of this year. Running UDM Pro in ADMZ for Full 3 gbps. After reboots it levels out for about a day, but after that it’s constant pink spikes to 60 plus ms. Bell support was less than helpful over the 20 calls I’ve had with them. Not sure what else to do.

While individuals may offer suggestions in this forum, it's helpful to remember that Bell Canada does not support third party hardware and software beyond the modem and a direct connection to your computer or devices. The Bell Canada forum on DSL Reports has a strong user community that can offer suggestions on third party hardware and software. The Bell Canada Redit can also offer user informed, third party information. Neither are supported by Bell.

Hi,

Is anyone else experiencing bad latency when using ADMZ on the GigaHub - FW 2.13?

I have a UDM SE (Unifi Dream Machine) connected to the GigaHub 10G port using a short CAT6 cable. I turned on ADMZ using the MAC address of the UDM and rebooted the GigaHub/UDM. Immediately after doing that, I am noticing terrible latency. I am monitoring latency using WinMRT to 1.1.1.1 (CloudFare public DNS).

This is a screenshot from my UDM monitoring latency:

My latency testing using MTR:

I am not interested in PPPoE / Double NAT due to their own issues. For what it's worth, Double NAT has no latency issues. PPPoE does have sporadic latency issues as well but nowhere close to what I see from ADMZ.

I tried speaking with L2 support but they told me they don't care about latency at all for residential customers - they only care about speed to the modem and nothing else. Is this true?

Wanted to add a bit more detail on what I have tried so far:

- Wifi on GigaHub is off

- Tried power cycling in various orders over the past 2 days. No luck. I occasionally get a few hours of good latency, then suddenly the connection drops completely on the UDM. I power cycle both devices and then the latency issue is back.

- Removing the UDM SE out of the picture and connecting straight to the GigaHub - same issue

- Factory reset the GigaHub and the UDM SE several times each - no luck

Any other suggestions people have? I need the UDM to maintain a stable connection on a WAN IP and avoid PPPoE as it has it's own set of issues.

I just did another test after several power cycles of both UDM and GigaHub (FW 2.13) - same problem:

I have the same issue on PPPoE - have you found a resolution to this by any chance?

[DPS1]

Although I’ve not been focussed on this blog for the last number of months, I don’t recall anyone having real success with ADMZ. PPOE is working perfectly for me in a UDM Pro Max.

Thank you for the reply.

The issue with PPPoE is the noticeable overhead. I have a brand new UDM SE connected on 10G and see the following:

- Not getting full 3gbps bandwidth

- Quite a bit of bufferbloat - notice the loaded vs unloaded latencies. (yes, i tried adjusting the MTU but no luck). Can be verified on waveform as well.

- WinMRT also points to increased latencies. These usually happen every 20-30 seconds or so - i get spikes into the 50-70ms range.

Curious, I know the UDM Pro MAX has twice the processing power vs the SE. Are you able to get the full 3gbps and no latency spikes via PPPoE on that hardware? If so, i may try to get my hands on one.

Thanks in advance for the help!

How is it connected? ADMZ and performing PPPOE connectivity, or using the 10G ethernet out on the 4000 hub?

The speed test, you would have to try with and without your UDM, to ensure the remote test server is able to provide 3/3 test speeds.

I would perform the speed test and the 330 packet test using the home hub without the UDM and with the UDM, to be able to compare properly against the above results.

Your question isn’t quite right. It’s one or the other. It’s either ADMZ or PPOE. They do not work in partnership with each other. I’m using PPOE and although my giga hub is actually bridged, prior to bridging it I was getting more than three up and down connected directly to the 10 gig port with a 10 gig  nic in my pc.  now in PPOE mode through my UDM ProMax  I’m still getting more than three up and down. 

[OctoInferno]

Yup! I’m fully aware they are different. My goal is to have UDM get a WAN IP and have a decent latency and a stable connection. To achieve this, we have 2 options - either ADMZ or PPPoE. I tried both. ADMZ would be preferred because PPPoE adds quite a bit of overhead and the protocol was never meant to be used in multi-gig setups.

thanks for the info on the ProMax - I may look into getting one - it has twice the processing power as my SE so that may be part of the issue. How is your latency in PPPoE vs Double NAT? I find that double NAT gives me the most stable connection and full speed - the only issues is the double NAT… 😞

[Vanadiel]

There's no official bridge mode in the home hub 4000, only ADMZ as closest to a bridge mode.

There is the unsupported bridge mode, but I don't think that one is stable as it's not officially supported. 

There's also the unsupported PON method for the home hub 4000, but that is not officially supported either.

Unless you have a home hub 3000 with a removable GPON, you cannot bridge the home hub.

[Vanadiel]

With a single connection it will show and log no internet connectivity if you loose the internet connection. 

If you ping an internal switch no such even will be logged as it will not be loosing connection to your switch.

[OctoInferno]

The Bridge mode is not really a bridge mode - it just turns off almost all services on the GigaHub and you still have to go through PPPoE encapsulation.

I have a Custom XGS-PON SFP+ Stick Module, ONT w/t MAC function mounted. I am going to try to bypass the GigaHub altogether. What a complete garbage piece of hardware it is.

double nat will always be faster as there's no overhead, but a disaster in every other way. I tried for a couple months before the more recent UNIFI RC firmware releases and struggled to get to many websites, couldn't get my site to site tunnels working and nor could i get the wireguard VPN to work. I guess for a plain vanilla set up maybe, but it was awful for me.
