  1. Could you send email to xianjun.jiao@ugent.be to introduce your self? Yes, already sent.

  2. Our image is used directly or you build your own image? Your image is used directly. I used the image "openwifi-1.4.0-notter.img" unzipped from "openwifi-1.4.0-notter.img.xz".

  3. What is your own modification? No modification

  4. Versions: OS, Vivado, openwifi/openwifi-hw repo branch and commit revision Ubuntu 20.04, window11 ,Just use openwifi-1.4.0-notter.img for Quick start.

  5. Board/hardware type Antsdr E316(AD9361 + Xilinx Zynq 7020 SoC)

  6. WiFi channel number Default 5g（36）and 5g （48）

  7. Steps to reproduce the issue, and the related error message, screenshot, etc image Use a windows computer (win 11) to connect openwifi and ping the ap. image Use the other e316 (AD9361 + Xilinx Zynq 7020 SoC) with ap-client-two-sdr mode. image image Change to 36 channel image image Change to 2.4g channel image image

Use ad-hoc-two-sdr mode image image image image image

How to get very low delay ping time as shown in openwifi introduction? Should I change some configs? Or change devices? Thanks in advance!

You can try to play with some parameters/registers, like: https://github.com/open-sdr/openwifi/blob/master/doc/app_notes/frequent_trick.md https://github.com/open-sdr/openwifi/blob/master/doc/README.md
