Hi all, I'm trying out compat-wireless-2010-07-29 with openwrt/trunk@22474 patches on AR913x and quite often (a few times a day) run into a problem where my laptop thinks it's associated but the router thinks it's not. Basically, on the laptop side I am still associated but on the access point iw says there are no stas: root@OpenWrt:/sys/kernel/debug/ieee80211/phy0# iw dev wlan0 station dump root@OpenWrt:/sys/kernel/debug/ieee80211/phy0# The log looks like this: Aug 7 14:53:24 OpenWrt daemon.info dnsmasq-dhcp[1601]: DHCPREQUEST(br-lan) 192.168.1.241 00:17:f2:51:b2:2d Aug 7 14:53:24 OpenWrt daemon.info dnsmasq-dhcp[1601]: DHCPACK(br-lan) 192.168.1.241 00:17:f2:51:b2:2d Aug 7 14:56:19 OpenWrt daemon.info hostapd: wlan0: STA 00:17:f2:51:b2:2d WPA: group key handshake completed (RSN) Aug 7 14:56:19 OpenWrt daemon.info hostapd: wlan0: STA 00:17:f2:51:b2:2d WPA: received EAPOL-Key 2/2 Group with unexpected replay counter Aug 7 15:06:19 OpenWrt daemon.info hostapd: wlan0: STA 00:17:f2:51:b2:2d WPA: group key handshake completed (RSN) Aug 7 15:06:19 OpenWrt daemon.info hostapd: wlan0: STA 00:17:f2:51:b2:2d WPA: received EAPOL-Key 2/2 Group with unexpected replay counter Aug 7 15:16:20 OpenWrt daemon.info hostapd: wlan0: STA 00:17:f2:51:b2:2d WPA: group key handshake completed (RSN) Aug 7 15:16:20 OpenWrt daemon.info hostapd: wlan0: STA 00:17:f2:51:b2:2d WPA: received EAPOL-Key 2/2 Group with unexpected replay counter Aug 7 15:16:20 OpenWrt daemon.info hostapd: wlan0: STA 00:17:f2:51:b2:2d WPA: received EAPOL-Key 2/2 Group with unexpected replay counter Aug 7 15:26:22 OpenWrt daemon.info hostapd: wlan0: STA 00:17:f2:51:b2:2d IEEE 802.11: deauthenticated due to local deauth request Aug 7 15:30:14 OpenWrt user.debug kernel: ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x40000020 Aug 7 15:30:14 OpenWrt user.debug kernel: ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 Those "unexpected replay counters" messages are quite common. What can cause these? A lost ack and retransmission? Apart from that I guess there are two questions here: (1) why was the association lost on the ap side? and (2) why is there no indication from the router that it does not expect data frames in this state? /Björn -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
