Hi, I am trying to enable the Auto Channel Selection (ACS) in hostapd with ath5k and ath9k drivers. 1) I cloned the source of hostap from the git and applied the patch 2) I then went to the hostapd directory of hostap and did make and make install. While building i enabled CONFIG_ACS=y in defconfig present in /hostap/hostapd/ and then copied to .config and performed the build. I then did a make install and configured the hostapd.conf file. Hostapd is working fine for me without ACS but when i enable channel=0 or channel=acs_survey and uncomment the acs_num_req_surveys=10 and acs_roc_duration_ms=5 options for ACS to be enabled it throws this error when starting hostapd, Configuration file: hostapd.conf Line 113: set as '0' tries to enable ACS but CONFIG_ACS disabled Line 125: invalid acs_num_req_surveys 10 (CONFIG_ACS disabled) Line 126: invalid acs_roc_duration_ms 5 (CONFIG_ACS disabled)1..5000) 3 errors found in configuration file 'hostapd.conf' Infact i enabled CONFIG_ACS when building.Any pointers on what to do to enable ACS please. Awaiting your kind reply.
