Hello
I have one customer with a 1000/300 FTTH Line.
I have installed to him one Hap AC 2, with latest long-term firmware.
I have a plain bridge, with hardware offload on it, I have enabled IP Fasttrack on the router.
Plain IP masquerade on it.
On the ETH1 is connected the ONU, and I tag the VLAN on it.
No PPPoE, only plain dhcp-client.
If I do the bandwidth test with the core router (at the end of the FTTH Line), I am able to transfer 900/300Mbps UDP traffic.
If I do a public speedtest from a PC connected at 1Gbit, I am not able to do more than 450mbps.
If I replace the MT with a AVM 5490, I easily reach 900Mbps/300
I tried also without bridge, with the IP on the eth port directly. no differences.
I tried with the dhcp-snooping disabled, hardware offload always enabled and H present.
CPU usage 5%
Counters in fasttrack moving quickly!
Everything looks fine but no throughput.
bandwidth test UDP between router and core router 900/300 Mbps.
The difference is after “NAT” masquerade, I tried multiple speedtest.net with multiple streams and different servers.
The server I test with is in direct peering with our network… so 2hop from us in fiber.
Tried with no avail.
With the fasttrack the forwarding traffic is very fast and the cpu is very very low.
No apparent issues, but no throughput. The customers complains that in speedtest doesnt see 900mbps as his neighbour with AVM Fritzbox 4040…
Both of them are my customers, one with MT, the other with 4040… I am quite embarassed.
Maybe the problem in tagging the VLAN on the wan port (eth1) ?
I cannot do different.
I don’t think it is the device, but maybe the config or something in the environment.
My suggestion will be go back to basics, the beginning, do factory default the device and test.
Pending results, you should do further troubleshooting and keep support@mikrotik.com in the loop.
Also post updates here, maybe as you go through steps, someone might notice something skew
I remember I was doing a throughput test on the hAP ac² and it could reach 900 Mbit/s while routing between LAN and PPPoE client as WAN with NAT. So the hardware as such is fine, the question is why the throughput is so limited in your particular configuration. What does /interface ethernet monitor ether1 show - could it be that it has negotiated 1000 Mbit/s half-duplex?
It should not be unless there’s a bug. You can try to create an /interface bridge name=br-wan protocol-mode=none, then switch on safe mode, and send the following line: /interface bridge port add bridge=br-wan interface=ether1 ; /interface vlan set [find name~“openfiber”] interface=br-wan
This will change the VLAN processing a little bit so if there is an issue when /interface vlan is attached directly to an ethernet interface, this may help. But I somehow hesitate to believe it.
But there’s another question - do we talk about IPv6 testing or IPv4 testing? I have never tried IPv6 routing throughput, so if the test PC uses IPv6, it may change a lot - first, the hAP ac² itself may have some issue with IPv6 throughput, and second, something else upstream may have such issue whereas the Fritzbox client doesn’t use IPv6.
