Latest firmware. Xfinity gigabit plan. Everything left equal aside from the ax box. Running on 5ghz HT80 mode (S10 doesn't support 160 and it was slightly slower and inconsistent when I tested it independently against HT80). Channel 161 with no interference.5 feet from routerWiFi 5Speedtest 727/42Fast.com 900/40WiFi 6Speedtest 604/41Fast.com 740/40BedroomWiFi 5Speedtest 422/41Fast.com 550/40WiFi 6Speedtest 343/42Fast.com 400/40I was interested at the results and figured I'd share mine in case anyone else was looking for some speed tests with a WiFi 6 enabled device. I hope WiFi 6 will only improve from here on out.

More interesting would be the PHY link speed negotiated at these locations with the two standards - check the Network Details along with each test. Convinced you see - at least on the short range tests - link rates above the max 866 Mbit/s (2x2, HT80, 400 ns guard, 256-QAM, 5/6 coding) - otherwise some of these higher Wi-Fi 5 numbers would not be possible at all. Based on the numbers, knowing the S10+ is a 2x2 WiFi radio, you have not tested a "standard" 802.11ac, much more 802.11ac with the non-standard 1024-QAM - and this the key component is where most of the performance "advantage" for 802.11ax (WiFi 6) is coming from. Still, your Wi-Fi 6 test numbers are lower from what I would expect in the comparison.

1024 QAM is for AX which is standard regardless of Broadcom or Qualcomm , 1024 QAM on AC however is not standard and is a Broadcom proprietary addition which only works between their router chipsets and client chips. It doesn’t matter if you have the Sanpdragon or Exynos version Samsung is using a BCM chip for WiFi. It’s the Broadcom BCM4375 in the S10 and as far as I know, no HT160.HT160 is more susceptible to interference and can lead to reduced range depending on your environment so unless you’re benchmarking or something, not much of a loss by not having it on a phone.Samsung has been using Broadcom WiFi chips on their Galaxy S series devices for quite a while. But yeah the one in the S10 supports AX (WiFi-6).

Just did some looking based on your response and on ac I'm showing 866 and on ax I'm showing 1200 when 5 feet from router. What you said about the non standard ac makes sense and unfortunately there's no switch (at least that I can see) that would take me off 1024, just HT20/40/80/160.But yeah, first speedtest this morning on ac showing 866 PHY was 816/41 and on ax showing 1200 PHY, I ran 3 tests and highest I achieved was 586/42 so it's definitely a little odd.

Huh I had responded with a picture attached but now it's not showing up. Anyway, thanks for your response. Your explanation about the non-standard ac makes sense. Unfortunately I can't test any other way as the only toggle is for HT20/40/80/160, but QAM is always at 1024.ax showing 1200 PHYac showing 866 PHYFirst ac test this morning came back 816/41Ran three ax tests and fastest I got was 586/42So it's definitely a little odd at this point, but hopeful it will improve with software tweaks.

More than 800 or even 900 as you listed before sounds almost resp. completely impossible on a 866 Mbit 802.11ac PHY.
