Re: [ATH6KL]: driver only supports limited channels in 5GHz band

At first glance, seems it does DFS.

What does your supplicant logs say (please run with verbose logging enabled).

Actually, are you trying to use wpa_supplicant in AP mode?  Normally it is
for stations and hostapd is used for AP mode?

Thanks,

Yeah, as Mr Minor said, you need DFS support there.

Maybe ath6kl doesn't support that.

hostapd logs in verbose mode might confirm that.

iw phy phy0 info

may provide more details on what your NIC claims to support.

And, unless there is reason not to, please keep the list CC'd so that
others can benefit from the discussion and also help offer ideas.

Hi all,

we using Linux v3.14 with upstream ath6kl driver and seeing some
issues when configuring softap mode in 5GHz band.
When we use a softap configuration in 5GHz band only these channels
seem to work (36-40-44-48). Using any other channel cause the AP not
to work.

The softap configuration we use is this:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
fast_reauth=1
update_config=1

ap_scan=2
network={
ssid="ath6kl-ap"
mode=2
frequency=5240 -- works
# frequency=5260 --fails
key_mgmt=WPA-PSK
proto=RSN
pairwise=CCMP TKIP
psk="12345678"
group=CCMP TKIP
}

Is that a know issue?
Is there any specific configuration necessary to make the other
channels working in 5GHz band?

This is our firmware configuration.
ath6kl: ar6003 hw 2.1.1 sdio fw 3.4.0.225.TABLET_DONGLE  api 4
ath6kl: firmware supports:

sched-scan,sta-p2pdev-duplex,rsn-cap-override,sscan-match-list,rssi-scan-


thold,custom-mac-addr,tx-err-notify,sched-scan-v2,regdomain-v2,large-connect-ie

Any help would be appreciated.

Thanks,
