Hi Jacek, summarising all information from the mailinglist the following configuration should work:
1. select CONFIG_PACKAGE_ATH_DFS=y 2. if ath9k select CONFIG_ATH_USER_REGD=y if ath10k deactivate CONFIG_ATH_USER_REGD 3. compile current OpenWRT trunk 4. Configuration --------- config wifi-device radio0 option type mac80211 option channel 104 option hwmode 11a option path 'pci0000:00/0000:00:00.0' option htmode HT20 option country 'DE' config wifi-iface option device radio0 option network lan option mode ap option ssid OpenWrt option encryption none --------- If this setting does not work for you please do the following. - on AP exec "wifi down" - on AP exec "logread -f" (on a second ssh session) - on AP exec "wifi up" - send us the log output + "iw phy0 info" output + information about your hardware Martin On 7/4/14, 4:29 PM, Jacek Kikiewicz wrote: > Hello, > > I have CONFIG_PACKAGE_ATH_DFS=y and still cannot use this... any idea how / > what should be debugged? > > Jacek > > > On 03.07.2014 18:14, Martin Garbe wrote: >> The command "iw phy ..." only shows hardware capabilities.
