Hello list
I have trouble with miniPCI Atheros AR5211 based card and 802.11a mode
on Freebsd 7.1 and 7.2 PRERELEASE
Notebook: Pentium M 1.5GHz
from FreeBSD 7.2 generic kernel
dmesg
------------------------
ath0: <Atheros 5211> mem 0xe0200000-0xe020ffff irq 10 at device 6.0 on pci2
ath0: [ITHREAD]
ath0: WARNING: using obsoleted if_watchdog interface
ath0: Ethernet address: 00:ff:f3:a0:28:02
ath0: mac 4.2 phy 3.0 5ghz radio 1.7 2ghz radio 2.3

pciconf
------------------------
ath0@pci0:2:6:0: class=0x020000 card=0x7005144f chip=0x0012168c
rev=0x01 hdr=0x00
vendor = 'Atheros Communications Inc.'
device = 'AR5211 802.11a/b/g Mini-PCI Wireless Adapter'
class = network
subclass = ethernet
------------------------
When I try to operate in 802.11a mode the card associate with AP but
can't send packets.
I try ping and check that the packets go through firewall but disappear
somewhere, in tcpdump I don't see send packets.
I try to ping my notebook from other PC and in tcpdump I see "arp
who-has" and other packets from other PC but again no packets from
AR5211 card.
In 802.11b mode card is working fine.
I try the card on windows and its working.
ahtstats output:
13 data frames received
2 data frames transmit
65 long on-chip tx retries
4 tx failed 'cuz too many retries
1M current transmit rate
28 beacon miss interrupts
1746 tx management frames
2385 tx frames discarded prior to association
1703 tx frames with no ack marked
884 rx failed 'cuz of bad CRC
30 periodic calibrations
2 rfgain value change
7 avg recv rssi
-96 rx noise floor
24 phantom beacon misses
53 tx discarded 'cuz queue is full
Antenna profile:
[0] tx 1739 rx 0
[1] tx 0 rx 6942
"tx discarded 'cuz queue is full" counter increased with ping packets.
I try AR5006 based PCcard and it working fine on FreeBSD 7.1 and 7.2
It seems that only AR5211 driver have problems and can't send packets.
