Couldn't get openwifi to work at 2.4Ghz #252

  1. Could you send email to xianjun.jiao@ugent.be to introduce your self? I've already sent it.

  2. Our image is used directly or you build your own image? I used your image.

  3. What is your own modification? Hello, Dr. Jiao, I have been trying to make the openwifi board work in different frequencies recently, and I want it to work in the AP mode of 2.4Ghz. So I modified the openwifi/hostpad-openwifi.conf on the board: before: `interface=sdr0 driver=nl80211 country_code=BE ssid=openwifi hw_mode=a channel=44 supported_rates=60 90 120 180 240 360 480 540 basic_rates=60 90 120 180 ieee80211n=1

    ht_capab=[SHORT-GI-20]

    require_ht=1 after: interface=sdr0 driver=nl80211 country_code=BE ssid=openwifi hw_mode=g channel=9 supported_rates=60 90 120 180 240 360 480 540 basic_rates=60 90 120 180 ieee80211n=1

    ht_capab=[SHORT-GI-20]

    require_ht=1 I just modifed the hw_mode and channel. After I run the./wgd.shand./fosdem.sh,I couldn't see the 'openwifi' on my phone , sometimes the I could see it ,but it just disappeared when I try to connect to it. I also tried using ./fosdem-11ag.sh and modifing the 'hostpad-openwifi-11ag.conf' , but it also failed. I compared./fosdem-11ag.sh with./fosdem.sh and hostpad-openwifi-11ag.conf with hostpad-openwifi.conf. The code is the same in the version 1.3.1,. So, does this (Use "./wgd.sh 1" to enable experimental AMPDU aggregation on top of 11n) (Use "./fosdem-11ag.sh" to force 11a/g mode)` in the README/QUIK START works?

WIFI in the 2.4G band can work properly, but it needs to be in a good electromagnetic environment,

Now it works better than before: https://github.com/open-sdr/openwifi/releases/tag/v1.4.0

Why openwifi needs to be in a good electromagnetic environment when working in the 2.4G band?
