Hello everyone. I have small issue with my hap ax^2 Mikrotik router. I use cable internet connection where I have ISP router in bridge mode and after that use Mikrotik router. Internet connection speed is 1Gbps, but when I measure connection speed always get less, around 600Mbps. If I connect my laptop directly to the ISP router I get around 900Mbps. Can someone tell me why? Mikrotik router settings are default.
No idea, you should be getting in the 900ish range with that device.
Default settings would not cause slowdown. What firmware are you using?
7.12 is current firmware. Exactly, this router should provide easily this speed.
Post the config, it will have to be there then… sounds like fastrack is disabled or in conflict with another part of your config!!! Which would mean not exactly default.

NOT default.
But should not be slowing your router down regardless ???
- You can remove default static rule…
/ip dns static
add address=192.168.88.1 comment=defconf name=router.lan
-
You can add some external servers…
/ip dns
set allow-remote-requests=yes servers=1.1..1, 9.9.9.9 -
You can drop the two rules you added…
add action=drop chain=input dst-port=53 in-interface=ether1 protocol=tcp
add action=drop chain=input dst-port=53 in-interface=ether1 protocol=udp
They are already handled by the default rule.
/ip firewall filter
add action=drop chain=input comment="defconf: drop all not coming from LAN" in-interface-list=!LAN[/i]
4. try that, dont think it will make a difference, still looking…
Is that test being done also with direct cable connection to AX2 ?
If Wifi, a bit normal …
I forgot to mention, it is on wifi. Is there any chance to get better speed via wifi? Distance between pc and router is only 2 meters.
You should have told that from the beginning… comparing apples to oranges and putting everyone on the wrong track.
Don’t expect via wifi to get to 1Gbps, not even 900Mbps (700-750 is about the max under normal conditions).
Default checklist for wifi:
- set your frequency manually
- make sure to use a frequency free of interference
- avoid DFS ranges
- don’t use WPA security (if possible, WPA3 only)
- for the rest you can keep wifi settings as default as possible, they should mostly be ok.

a secret configuration?
986 Mbps over wifi ? That’s Gigabit ethernet.
No it’s just the way I point my antennas, one Horizontal and one virtical. If I point them straight up virtical I get about 780/830Mbps.
Nope thats wifi. I don’t have ethernet on my laptop!
Took me a little while to redact these…
What about config? You wont share it? 
It isn’t the config it’s just 80 wide channel 5180 but I do have old router antennas plugged into my laptop card via pigtails.
As I said the configuration of my antennas are one Virtical and the other Horizontal. Also depends on what version I run atm 7.14beta 8.
This is a test from across my lan..

Maybe Mikrotik have an explanation why I get those speeds over wifi, maybe the router is just spouting rubbish who knows!
For real measurements you better test with iPerf instead of (any other) speedtest.
