Description

When trying to use a channel that requires DFS, the wireless interface doesn't come up because of the DFS failure:

Configuration file: /etc/hostapd/conf.d/5GHz
wlan1: interface state UNINITIALIZED->COUNTRY_UPDATE
wlan1: interface state COUNTRY_UPDATE->HT_SCAN
wlan1: interface state HT_SCAN->DFS
wlan1: DFS-CAC-START freq=5260 chan=52 sec_chan=1, width=0, seg0=0, seg1=0, cac_time=60s
DFS start_dfs_cac() failed, -1
Interface initialization failed
wlan1: interface state DFS->DISABLED
wlan1: AP-DISABLED
hostapd_free_hapd_data: Interface wlan1 wasn't started

DFS has been enabled in the firmware build configuration file.

Firmware version: trunk r42344
Hardware: Netgear WNDR4300

Attached are the kernel log (dmesg.txt) and the hostapd configuration (hostapd.conf). Not using UCI for wireless configuration.

DFS only works with 20MHz channels for now. Can you try if it works with option htmode 'HT20' in /etc/config/wireless?

As for me, it does not work even in HT20 mode
