    STA-to-STA OFDMA issue?

    It was not me who took the screenshot. But I'm talking about exactly that part of the code where the enabling of OFDMA is deactivated. look at the last line. There is an unconditional shutdown of the OFDMA. and the condition (dependence on the ofdma flag in the web interface) is commented out...

    STA-to-STA OFDMA issue?

    Hmm ... If you believe this, it looks like OFDMA is permanently disabled in the AX55 firmware. And the position of the OFDMA checkbox does not play any role. Maybe that's why the issue was not noticed on a router with a qualcomm chipset? Is there a way to check the real working of the OFDMA at...

    STA-to-STA OFDMA issue?

    I did a similar test on TP-Link AX55, where the Qualcom chip is used. There is no such glitch.

    Regarding OFDMA issue, another answer came from the TP-link support:

    STA-to-STA OFDMA issue?

    I was able to perform additional speed tests on the AX73 router with Intel AX200 and AX210 clients running in AX mode. This time I used two independent server-client pairs working simultaneously (LAN-> WLAN) + (LAN-> WLAN). That is, the Iperf3 servers are connected to the router with a cable...

    STA-to-STA OFDMA issue?

    What kind of router are you using? And can you try to disable OFDMA, but leave MU-MIMO ON?

    STA-to-STA OFDMA issue?

    Great test, thanks! It would also be nice to understand - this happens with any client, or only with Intel.

    STA-to-STA OFDMA issue?

    Yes, 160MHz does not matter, since I saw a similar effect on the AX20, but there is no 160MHz

    STA-to-STA OFDMA issue?

    By the way, I use the following router settings: Power high, channel 36, width 160, WPA2 / WPA3-Personal, 802.11a / n / ac / ax mixed TWT, Smart Connect - OFF MU-MIMO, WMM, Airtime Fairness, Zero Wait DFS - ON I tried different combinations of these settings, but I did not find anything critical...

    STA-to-STA OFDMA issue?

    Unfortunately, I will not be able to repeat the tests in the near future - now I have only one client AX. But in the WLAN->WLAN test, this is exactly how it turns out - one client is DL, the second is UL ... I think it doesn't matter. Moreover, the TP-link does not make it possible to separately...

    STA-to-STA OFDMA issue?

    Yes, that's understandable. In the test with one client (LAN->WLAN), the Wifi speed is close to 1 GB - the limitation of the LAN port affects. But I will say more. If we take two wireless clients + two wired servers and simultaneously conduct two parallel sessions of iperf3 (LAN->WLAN +...

    STA-to-STA OFDMA issue?

    Unfortunately, at the moment there are practically no independent tests. Therefore, it is unclear whether this problem concerns only the combination of tp-link->intel or broadcom->intel or some other equipment (router, chipset, client card) variations. It is possible that routers with a Qualcomm...

    STA-to-STA OFDMA issue?

    Well, everything is fine with the Internet in Russia. Many already have an Internet channel from 200 Mbps to 1 GB. In this case, the speed is symmetrical. Plus, many users have several clients at home, NAS, media players and other devices, so the speed within the local network, from client to...

    STA-to-STA OFDMA issue?

    I got further clarification from the support, but they do not clarify much. "According to information from the developers, this problem with OFDMA manifests itself on routers from other manufacturers and is related to the OFDMA technology itself. Therefore, it is quite possible that if you buy...

    STA-to-STA OFDMA issue?

    The command I use is the simplest one: iperf-3.1.3-win64 \ iperf-3.1.3-win64 \ iperf3.exe -c 192.168.1.70 -R -P 8 -t 30 The result does not depend on the direction server-client or client-server. The TP-Link support answered me that the problem is not in their firmware, but at the global level...

    STA-to-STA OFDMA issue?

    Thank you, I read it, of course. But, "Conclusion: OFDMA does nothing to improve aggregate throughput." and "My conclusion at this point is that OFDMA produces no discernable benefit for the average consumer."- this is not the same as degrading three times the throughput in my test. OFDMA...

    STA-to-STA OFDMA issue?

    Good day! I did one test with a WiFi 6 router and it was very frustrating for me. I wrote about its results to the manufacturer's support, and after a long period the support answered me, that the problem was not on their side, but global - in the OFDMA technology itself. So I would really...
