Hello,

Today I upgraded my laptop from 5-STABLE to 6-STABLE. After the
upgrade, my wireless is not working anymore.

This is my wireless card:

Nov 6 10:05:06 snowlap kernel: ath0: <Atheros 5212> mem 0xf7de0000-0xf7deffff irq 11 at device 12.0 on pci2
Nov 6 10:05:06 snowlap kernel: ath0: mac 5.9 phy 4.3 5ghz radio 3.6
Nov 6 10:05:06 snowlap kernel: ath0: Ethernet address: 00:0b:6b:35:f9:8f
Nov 6 10:05:06 snowlap kernel: ath0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
Nov 6 10:05:06 snowlap kernel: ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
Nov 6 10:05:06 snowlap kernel: ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
Nov 6 10:05:06 snowlap kernel: ath0: turbo rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps

which I enable with:

ifconfig_ath0="inet 172.16.10.10 netmask 255.255.255.0 ssid wrap.unixguru.nl weptxkey 1 deftxkey 1 wepmode on wepkey $mysecretkey"

After that, my card is up and running without any problem:

ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet6 fe80::20b:6bff:fe35:f98f%ath0 prefixlen 64 scopeid 0x2
        inet 172.16.10.10 netmask 0xffffff00 broadcast 172.16.10.255
        ether 00:0b:6b:35:f9:8f
        media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/54Mbps)

        txpower 60 rtsthreshold 2346 fragthreshold 2346 -pureg protmode CTS -wme
        roaming AUTO bintval 100

On my Wrap box (6.0-BETA2 and works with the same(!) card) my laptop is associated:

wrap# ifconfig ath0 list sta
ADDR AID CHAN RATE RSSI IDLE TXSEQ RXSEQ CAPS ERP
00:0b:6b:35:f9:8f 2 3 48M 52 240 370 6720 EPS 0

If I start a ping from 172.16.10.10 (laptop) to 172.16.10.1 (Access Point = wrap), I see the starting
arp packet on the wrap with tcpdump

14:11:38.091729 arp who-has 172.16.10.1 tell 172.16.10.10
        0x0000: 0001 0800 0604 0001 000b 6b35 f98f ac10
        0x0010: 0a0a 0000 0000 0000 ac10 0a01
14:11:38.091799 arp reply 172.16.10.1 is-at 00:0b:6b:35:e7:3a
        0x0000: 0001 0800 0604 0002 000b 6b35 e73a ac10
        0x0010: 0a01 000b 6b35 f98f ac10 0a0a

and on my laptop I see with 'tcpdump -n -i ath0 -y IEEE802_11' the following

14:10:56.038748 Beacon (wrap.unixguru.nl) [1.0* 2.0* 5.5* 11.0* 6.0 9.0 12.0 18.0 Mbit] ESS CH: 3, PRIVACY

14:10:56.135735 arp who-has 172.16.10.1 tell 172.16.10.10

but according to my ping command, if have a 100% packet loss.

My conclusion:
The 802_11 frame is recieved by my card, but not returned to the IP stack for some reason.

Some stats:
        snowlap# ./80211stats
        113 rx from wrong bssid
        14 rx discard 'cuz dup
        555 rx discard 'cuz mcast echo
        596 rx w/o wep and privacy on
        9658 rx discard mgt frames
        88027 rx beacon frames
        24 rx element unknown
        88 rx frame chan mismatch
        142 rx discard 'cuz port unauthorized
        43 tx failed 'cuz no defkey
        14 active scans started

        snowlap# ./athstats
        6 mib overflow interrupts
        229 tx management frames
        659 tx frames discarded prior to association
        11 long on-chip tx retries
        210 tx frames with no ack marked
        256 tx frames with short preamble
        109 rx failed 'cuz of bad CRC
        124 rx failed 'cuz frame too short
        10 rx failed 'cuz of PHY err
            10 CCK restart
        297 periodic calibrations
        4 rfgain value change
        18107 rate control checks
        2 rate control raised xmit rate
        rssi of last ack: 63
        avg recv rssi: 61
        1141 switched default/rx antenna
        Antenna profile:
        [1] tx 165 rx 60579
        [2] tx 640 rx 39202

What could be wrong? Did I overlook something?

Richard.
