Description

Since upgrading to Barrier Breaker rc3, I've seen the following in my logs:

Sun Sep 14 18:17:24 2014 daemon.info hostapd: wlan0: STA 34:bb:26:94:fb:eb IEEE 802.11: disconnected due to excessive missing ACKs
Sun Sep 14 18:17:25 2014 daemon.info hostapd: wlan0: STA 34:bb:26:94:fb:eb IEEE 802.11: authenticated
Sun Sep 14 18:17:35 2014 daemon.notice hostapd: wlan0: STA 34:bb:26:94:fb:eb IEEE 802.11: did not acknowledge authentication response

Sun Sep 14 18:18:44 2014 daemon.info hostapd: wlan0: STA 34:bb:26:94:fb:eb IEEE 802.11: authenticated
Sun Sep 14 18:18:44 2014 daemon.info hostapd: wlan0: STA 34:bb:26:94:fb:eb IEEE 802.11: associated (aid 2)

Clients on the 2.4ghz network loose connectivity during this process, though they still show that they are connected. This is a new issue with BB rc3, as I did not see it when running Attitude Adjustment.

dmesg shows the following:

[   94.610000] ieee80211 phy0: Selected rate control algorithm 'minstrel_ht'
[   94.620000] ieee80211 phy0: Atheros AR9280 Rev:2 mem=0xb0000000, irq=40
[   94.760000] ieee80211 phy1: Selected rate control algorithm 'minstrel_ht'
[   94.760000] ieee80211 phy1: Atheros AR9280 Rev:2 mem=0xb0010000, irq=41

The also does not seem to affect 5ghz clients. I've seen the issue on both phones and laptop devices.
