I have a Mikrotik hAP ax2 and so far I had a 100/100 Mbps connection so I didn’t pay attention to it,
but I recently changed the operator and I have a 950/950 Mbps connection,
when I run a speedtest via cable, my download and upload speeds are around 920-930 Mbps, so OK
However, the problem concerns the speedtest performed on WiFi where I have the following speeds:
download: 280-320 Mbps
sending 590-740 Mbps
I checked on several devices, including several with the WiFi 6 standard, and the results are similar on all of them
I also performed the test on several devices at the same time.
Generally, these speeds are sufficient for me, but I wonder if there is something I can do to get better results?
Can you perform a speedtest by using iPerf? Preferably via a computer connected through cable and a wireless device?
At what speed is the client connected (Rx and Tx Rate, can be found on /interface wifi registration)?
Hm, no. If the screenshot is what you currently achieve with your WiFi, then the best is actually the double of that 400Mbps value. WiFi is half-duplex. When you test both Tx and Rx at the same time with the same rate, you’ll achieve about half what you would get in a normal situation where you are either only downloading something (upload will only use a few Mbps for ack packets) or uploading something (the reverse).
then explain to me why I only get 320 Mbps on download and 740 Mbps on upload,
I understand that when I test download and upload at the same time, I have half-duplex, but why do I have such a big difference when testing download and upload ?
Because your devices and the hAP ax² don’t have the same antennas, antenna gain/sensitivity, transmit power, etc… and also maybe the interferences/noise floor at your devices’ location are not the same as at the router’s location, resulting in difference SNR (signal to noise ratio). Many factors can cause the asymmetry that you are observing. If you have time, read this page, including the appendices https://www.wiisfi.com/, it discusses all of the above and also ways to improve your WiFi network.
Yes, but the routers/APs have much better antennas with better sensitivity and gain. Transmit power is only one part of the equation. If the noise floor near the router is low, with better antennas the router can get more out of a weaker received signal level.
Ok all understood, your shoving your phone/phones next to the router when testing, ok so another question.
When you play a youtube video on your phone and look at the router connection rates does yours show 1201Mbps TX RX rate ?
Example:
So as you can see my laptop is 3mtr away from my Hap ax2 with a lock of 1201 TX/RX
The other two items are in another room with 980Mbps about the same distance away, your saying your Phone/phones are next to the router then you need to do a frequency scan and find a better frequency because speed isn’t going to happen with the above snapshot you posted!
