welp, if that didn't work, I suggest you to use own Router with DoH Support

I think ASUS models have the best DoT/DoH support? If i bridge the ONR will it break VoIP?

Technically it shouldn’t although I’ve not tried the VoIP as I no longer use a home phone.

Asus only supports DoT, it seems to come from Asuswrt-Merlin then got implemented back to stock firmware

DoH is not supported, and it seems like Merlin is not a fan of DoH so I don't think he will ever implement it (he does not like that dns traffic gets mixed in with http content)

with that said, there's probably something you can download and install on asuswrt-merlin

When in bridge mode, only bridge what ME 171 told to do, only VLAN500 get passed as tagged traffic and VoIP remain as is

Many reports D-Link speed would drop overtime

Any guesses/speculations why the speed drops overtime when in bridge mode?

This one I not sure, check RAM are fine and no visible memory leak, it appear to be random time at random OLT,
I thought FHTT OLT cause it, also effect on HWTC and ALCL OLT.

I finally encountered a speed drop issue when my VPN was connected to SG server. Initially, the connection was running at full speed for the first 5-10 minutes after the VPN was established. However, after some time, the speed capped at 320/150. Even after disconnecting the VPN, the speed remained capped at 320/150 until I rebooted the ONU unit.

No speed drop issue so far if I am not using any VPN service after the ONU rebooted. It happened again and again 10 minutes after the VPN was established.

Just wondering. Did you torrent or transfer lots of data after you turn on VPN?
If you turn on VPN and do nothing, does the speed still drop?

Yes. The speed is still capped after a certain period, even if I do nothing once the VPN is established. Is it possible to have a capping system that detects the change in the routing and then throttles the speed?

I'm not aware of such thing in D-Link but currently I suspect the 2.5G switch chip is overheating.
In the white D-Link, this external switch chip doesn't exist. All the functionality is provided by the SoC.

Do you happen to put the device in a confined space?

You have experiment and can trigger the speed drop as many times as you want just by connecting to VPN?

What VPN protocol did you use?

The ONU device is placed in an open area, and the ONU temperature is consistently below 20 degrees.

The speed drop only happens when connecting to a VPN (OpenVPN protocol). I tested many times and am pretty sure my line was capped after the VPN was established.

Just to be clear. You establish the VPN from your computer and not via the ONR right?
Do you use UDP or TCP for your OpenVPN?

As far as I know, middlebox don't have any special rules for OpenVPN, unlike IKE, GRE or some other protocol.

Does your VPN provider provide more than one SG server? Try to do a traceroute/mtr to the hostname of your current SG VPN server (while not connected to the VPN, obviously) to determine the peering/transit providers. Check with your other SG VPN nodes. Hopefully your provider has a different server on a different rack/datacenter using a different peering path. I’m asking because with certain peering providers, ISPs might perform some sort of load balancing, not to target you specifically, but mainly because they’re cheapskate and won’t pay peering providers for a bigger bandwidth pipe.

I tested both on my computer and on my own router (in bridge mode) using the UDP setting. Both are getting the speed capped too.

With bridge mode most of the control logic are turned off. Either something is happening at the OMCI or my earlier suspicion, the external switch chip.

But none of these know you are using OpenVPN.

Just to rule out the switch chip:
Can you try iperf between the 2.5G port and the other 1G port?
Just blast them with bi-directional data

I tested on 3 different SG servers (all 3 SG servers hosted by different telcos in SG) and got the same result which the speed was capped after some time. It's really strange that it happened only when the VPN was established. All back to normal after I rebooted the ONU without connecting to the VPN.

I recently got upgraded and was given the DPN-FX3060V combo box. Every time I leave the house or disconnect from the home internet, I can’t connect back to the wifi.

I need to restart the router every time in order to make a connection. Restarting the phone doesn’t work. Is there a way to troubleshoot this?

* the combo box come in default settings done by the technician.

Do you happen to use a USB-C dock?
What about other device? Can they reconnect?
What about already connected devices? Do they continue to work?
What if you manually disconnect your phone while you are home? Can it reconnect?
Can you pinpoint it to a single device that cause this issue?

Today I also reporting in.
