Dear All,
I'd like to get the "channel utilization" parameter when using AP mode in Raspberry Pi. When configuring hostapd service according to general linux configs:
# Channel utilization averaging period (in BUs)
# This field is used to enable and configure channel utilization average
# calculation with bss_load_update_period. This should be in multiples of
# bss_load_update_period for more accurate calculation.
bss_load_update_period=50
chan_util_avg_period=600
it makes the hostapd crash (sudo service hostapd start) shows an error and doesnt start.
How can I get this parameter up and running.
AND/OR - where from can I get the information of what is allowed when configuring all the Wi-Fi parameters - e.g. sudo iw dev wlan0 set txpower fixed 1000 works fine, but other parameters does not have any effect (e.g. not using certain rates/mcs's). How to get a list with allowed changed parameters for the wifi driver?
Solved! Go to Solution.

Hello:
bss_load_update_period=50, for this one I have seen this function has been supported in supplicant from 2015.
but I can't find any info from hostapd on this setting from hostapd.conf reference, would you please show more details? chan_util_avg_period=600

Hi,
thanks for the reply. Yes, bss_load_update_period=50 does not make the hostapd crash. But when adding channel_util_avg_period, it does.
The hostapd.conf reference (https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf 😞 has both items - i.e. the channel utilization is just below the bss_load_update_period in this file/web.
# BSS Load update period (in BUs)
# This field is used to enable and configure adding a BSS Load element into
# Beacon and Probe Response frames.
#bss_load_update_period=50
# Channel utilization averaging period (in BUs)
# This field is used to enable and configure channel utilization average
# calculation with bss_load_update_period. This should be in multiples of
# bss_load_update_period for more accurate calculation.
#chan_util_avg_period=600
Another question is, how you can get the result from it to the console, i.e. the value it calculates?

hello:
I think you need a check in the hostapd code to see if chan_util_avg_period is included in your version.
or you can take a newest hostapd ,supplicant code to compile a new one , and replace it in your system .

Thanks - how to check this? I.e. is there a command that shows which parameters/functions are included to be used in hostapd?
