Doesn't matter which DFS channel i choose, it won't start up.

It works fine on non-DFS channels.

Chaos Calmer build with the latest driver included.

Which WRT model do you have?

lantis1008 commented 8 years ago

1900ac v1

Thinking it is possibly a regulation issue? I'm in australia, which seems to have everything allowed (in our regulatory body) but the openwrt regulatory file might be out of date?. BUT, when i set my location to US, i can get DFS to start on channel 52. US

I did testing with country code RU which had the most DFS channels and results were the same. Testing in below posts.

Rebuilt with an updated reg domain database. DFS now works fine for me. Closing this issue.

How did you updated reg domain database?

lantis1008 commented 8 years ago

I recompiled and added a patch for it. I have the patch available here. https://github.com/lantis1008/gargoyle/blob/9df043d4884a630f366d47c7daa793680b262b87/patches-generic/120-latest-reg-domain-db.patch

The chaos calmer reg domain is like 12 months out of date. A lot of changes since then.

lantis1008 commented 8 years ago

I can also confirm with a spectrum analyser that I indeed am achieving 80MHz width @Chadster766 I follow the forum thread on openwrt and see that everyone is discussing that currently

Chadster766 commented 8 years ago

Is the analyzer showing 80Mhz for upper non-DFS channel +149? Please test any one of DFS channels your country code allows.

I'm guess this ability is tied to the OpenWRT hostapd custom code for the "option noscan".

lantis1008 commented 8 years ago

@Chadster766 yes it does. My settings are the same as my first comment except changed channel 52 to 149. I do not use no-scan option.

Screenshot attached. chadster

Chadster766 commented 8 years ago

Awesome, I must need your patch! I will post back with the results when completed.

Chadster766 commented 8 years ago

I updated the country code reg database using files from the kernel dev source: https://wireless.wiki.kernel.org/en/developers/regulatory/wireless-regdb

This resolved some of the issue but I also needed to change my hostapd 5Ghz wlan config file.

I changed ht_capab to a single 80Mhz option, removed vht_capab entirely and configured vht_oper_centr_freq_seg0_idx to the base channel + 6.

interface=wlan1
bridge=br0
driver=nl80211
ctrl_interface=/var/run/hostapd
ssid=McDebian50
ignore_broadcast_ssid=0
hw_mode=a
channel=100
auth_algs=1
wmm_enabled=1
ieee80211n=1
ht_capab=[HT40+]
ieee80211ac=1
vht_oper_chwidth=1
vht_oper_centr_freq_seg0_idx=106
ieee80211h=1
ieee80211d=1

wpa=2
wpa_passphrase=mcdebian123
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
country_code=US

Thanks for your help :smile:

I now get 80Mhz on the entire 5Ghz channel range including DFS!

lantis1008 commented 8 years ago

Yep that is the git source i wrote my patch from. Glad it could help you!
