Hi specialists,
I got a throughput issue with Intel BE200.
First, I found the tx and rx throughput was much lower than specifications of BE200 on 5G band.
tx was 1066mbps, and rx was 1129mbps.
Then I double checked the wireless connection information. It shows the link speed was 1441mbps. You know that there is a display issue with WIN11 connection link speed . It changes sometime, so I don't believe what it shows. But this time it could be the right value.
now, I got 1.4Gbps wireless link speed and throughput just over 1G. So I think there is a connection issue with Wi-Fi 7 router and Intel BE200.
To exclude the Wi-Fi 7 router issue, I used a mobile phone which chipset is Qualcomm 8gen3 with wireless FastConnect 7800 to connect the router, the link speed showed 3226mbps. That is 160MHz 5G (2882)+ 20MHz 2.4G(344) MLO=3226. To double exclude router issue, I used Intel AX210 to connect the router , the link speed showed 2.4Gbps, and throughput was 1.8gbps.
For now I have 90% sure the BE200 got a issue. But why? It is a antennas connection issue or Bandwidth issue?
After check the cable connection, I'm sure the antennas is good. I got a wireless capture between router and BE200 .
To compare the differences with Qualcomm 8 gen3, I captured as well.
You can see for bandwidth support on EHT, both BE200 and 8Gen3 are not support 320MHz in 6G, I don't why because they should support. That is another question.
160MHz in 5G or 6G is not showed on EHT PHY capabilities . But there are infomations showed on HE PHY capabilities: BE200 not support 160MHz in 5G and 6G, but 8gen3 support. That's why when I set BE200 worked in AX mode, the link speed was only 1.2Gbps.
To make sure the bandwidth issue, I login the router check the STA BW, and it showed EHT80.

Why BE200 is the same condition when working in BE mode only on 80MHz? How to fix it?

I was able to get 5.188 Gbps after updating the Windows driver to 23.80.0.7. This one is not available in the download section, I guess someone forgot to add it. But I found one here: https://treexy.com/products/driver-fusion/database/network-adapters/intel/wi-fi-7-be200-320mhz/.
