switch -> switch -> MT RB5009 -> VM (with it's own bridged adapter), and got 906 Mbit/s. Same test from my laptop through the WiFi card -> cAP ax -> RB5009 -> VM (same as mentioned before, and the only server used from here for testing) i do get 345 Mbit/s (poe pwr). So after these two tests i want to believe it's fair to exclude routing/firewall issues. Firewall is just as open from the WiFi clients network as the RPI for testing.Next i just did a reset of the whole cAP and connected the VMs physical adapter to ETH2 on the cAP and my laptop to the default WiFi. Changed the 5GHz radios SSID value to separate it for testing, but nothing more. Now with almost out of the box config i did get 571 Mbits/sec (poe pwr) and 657 Mbit/s (dc power), but i tested with "-P 5" (5 TCP streams) this time on iperf (I randomly tested this because of a couple hours of headache at work with throughput issues with firewalls where that was an unresolved issue). I did not write down any other test with the default config, but after going back to the previous setup with provisioned config i did test with 5 streams again and did then receive 489 Mbits/sec (poe pwr) and 611 Mbit/s (dc power). Not very good but not bad either.Now with provisioned config i went crazy and tested 15 TCP streams (which was the highest i got with stable results) and got 735Mbit/s (poe pwr. Got around the same with dc power). Now we are talking good speeds, but I'd love to reach even higher as the product is listed with 1200 Mbit/s 5GHz speeds (but i also understand printed WiFi speeds isn't something you necessary reach at all with any brand).Now my million dollar question is: Is this something other people experience too with MT, and/or is it something others experience in general with WiFi? Very little of what i find about WiFi speeds people have tested with both MT and other vendors specify in detail how the tests are done, but i do find people talking about achieving much higher 5GHz speeds with WiFi 6 than i get with a default iperf test. If not 1Gbit/s is realistic, I'd love to reach the 15 TCP stream speeds i got with general usage like copying things from my laptop to my NAS and back. Can i really expect to reach above 350 Mbit/s with a single TCP stream on this access point or WiFi 6 at all, or am i delusional for thinking so?(Yes i can provide config if anyone would like to see it, but until someone asks i like to believe it's just a MT thing instead of my config :P (It's messy too))Also: I do work with network administration daily, but WiFi is something i usually keep my hands off so i might sound both dumb and 🤓☝️ rn.

I was a little annoyed after buying the cAP ax and seeing the speeds i got never even reached 500 Mbit/s in the start (yes i have read a million comments about "wHaT dId YoU eXpEcT wItH mT wIfI" when researching a little, but hold on to them still. If i still seem stupid after reading the brick wall with text then throw it at me).For context both my RB5009 and cAP ax is at ROS 7.14.3. Only radios near enough to make interference was on a non overlapping channel, and all testing was done with 80MHz channels on the 5GHz band. All cabling and physical NICs is 1Gbit. I tested with the cAP ax both powered with poe from the RB5009, and the dc adapter directly in some occasions. My laptops WiFi card is the Intel® Wi-Fi 6E AX211 (and i'm not expecting WiFi 6E speeds i am fully aware this is cAP has plain WiFi 6). And all testing was done 20cm from the AP. All the speeds referenced are the receive speeds in iperf, and not more than a few Mbit/s lower than sender.I did a plain iperf test (no flags. 1 TCP stream default) between two VLANS through this setup: RPI -> switch -> switch -> MT RB5009 -> VM (with it's own bridged adapter), and got 906 Mbit/s. Same test from my laptop through the WiFi card -> cAP ax -> RB5009 -> VM (same as mentioned before, and the only server used from here for testing) i do get 345 Mbit/s (poe pwr).
