Hi All, I tried to set up a Linux based Variscite DART-6UL board WIFI as an access point using the hostapd.conf file and the hostapd(Ver: 2.9-rc0) application. In the hostapd.conf file, I made the following modifications: ssid=xxxxx hw_mode=a #(5Ghz) country_code=GB country3=0x20 ieee80211d=1 ieee80211h=1 hw_mode=a channel=36 local_pwr_constraint=3 The above settings worked fine and the DART-6UL board was successfully setup as an AP and broadcasted the given ssid. The messages logged by the HOSTAPD application are as follows: "showing that the HOSTAPD application is advancing with AP/channel configuration and finally logging the AP-ENABLED message." " hostapd_handle_dfs_offload: freq 5180 MHz does not require DFS. Continue channel/AP setup Proceed with AP/channel setup " " wlan0: interface state COUNTRY_UPDATE->ENABLED wlan0: AP-ENABLED wlan0: Setup of interface done. " However, the hostapd application seems to be not working if I attempt to set the channel to 100 and higher. channel=100 The messages logged by the hostapd application are " DFS support is enabled Completing interface initialization Mode: IEEE 802.11a Channel: 100 Frequency: 5500 MHz hostapd_handle_dfs_offload: iface->cac_started: 0 hostapd_handle_dfs_offload: freq 5500 MHz requires DFS " " hostapd_setup_interface_complete_sync: Wait for CAC to complete " Because the DFS-CAC is not yet up and running, the HOSTAPD application is unable to complete the AP/channel setup configuration. The system is unable to start/complete the DFS-CAC functionality despite having the DFS-CAC option enabled in the conf file. As a result, the hostapd programme is always waiting for the system to complete DFS-CAC configuration. Is there a problem with the hospad programme, or do I need to enable any other settings? Thank you for your support. Regards Nagaraj _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
