[Voyage-linux] wmm_enabled=1 breaks 802.11g clients

[Stuart Baggs]

Hi guys, I am running the daily build with kernel 2.6.30 with an a/b/g/n card running Atheros chipset AR9220. Everything works fine except one problem.

If I run hostapd with wmm_enabled=0 then any .11n devices which connect can only reach 54Mbps (as per the 802.11n standard, nothing new there). If I enable WMM (wmm_enabled=1) then only .11n client can connect.

I am now running hostapd 0.7.0 but the problems remain with 0.6.9.

My hostapd.conf looks like this:

interface=wlan0
driver=nl80211
ssid=Test Net
hw_mode=g
channel=1
auth_algs=1
ieee80211n=1
ht_capab=[HT20]
country_code=GB
ieee80211d=1
beacon_int=50
wmm_enabled=1

Does anyone have any ideas for me?

P.S. I have tried running hostapd with all the tx_ques etc but it makes no difference.

Thanks

Stuart
