 Posted: Tue May 14, 2013 11:08 am Post subject: [SEMI-SOLVED][ath9k] How to AR9280 & hostapd & 802.1 |
 |
|
I fight with this trio a few months. Before I had only 802.11g (54Mbps), but yesterday I changed kernel and hostapd.
Nowadays I have 802.11n (130Mbps) and this message when hostapd starting: | Code: | | rfkill: Cannot open RFKILL control device |
I have Atheros AR9280 card: | Code: | ieee80211 phy0: Atheros AR9280 Rev:2 mem=0xffffc90010ea0000, irq=16

What I want?
First of all, how to remove 'rfkill' message?
Second, how to enable full 802.11n support (300Mbps, MIMO 2x2)?

Baily ... you need to enable CONFIG_RFKILL ... its under: Networking support => RF switch subsystem support.

CONFIG_IEEE80211N is enabled by default in the hostapd ebuild. Unrelated, but unless you must use WPS then I'd suggest you disable that useflag, also you may not want/need ipv6.

The hostapd.conf seems fine, all the 80211N options are enabled.

The card is a AR928X and so should support the following (untested):
| Code: | | ht_capab=[HT40-][HT40+][SHORT-GI-40][TX-STBC][RX-STBC1][DSSS_CCK-40] |
HTH & best ... khay |

Still don't work, but I found this: | Code: | Neighboring BSS: 64:70:02:ae:b2:b8 freq=2437 pri=6 sec=2
40 MHz pri/sec mismatch with BSS 64:70:02:ae:b2:b8 <2437,2417> (chan=6-) vs. <2442,2462>
20/40 MHz operation not permitted on channel pri=7 sec=11 based on overlapping BSSes

I did it (almost). When my neighbor shut down his network, I restarted my hostapd and inSSIDer says that I using two channels.
Also inSSIDer says that "Max Rate" is 300Mbps, but my clients and AP shows only 130Mbps: | Code: | | tx bitrate: 130.0 MBit/s MCS 15 |
Why Leo, why? |
