Hi I have an Atheros AR9160 miniPCI board, installed in my Centrino laptop (but the laptop has only two antenna). When I run iperf (from ports benchmarks/iperf) to test 11n, the test cannot done. Console log says bb hang, but I can ping peer node without problems. I think AR9160 driver cannot work in heavy traffic loading. ~> uname -a FreeBSD lihong-nb 8.0-CURRENT FreeBSD 8.0-CURRENT #3: Tue Jun 2 21:24:53 CST 2009 root_at_lihong-nb:/usr/obj/usr/src/sys/LIHONG-NB i386 dmesg: ath0: <Atheros 9160> mem 0xc8200000-0xc820ffff irq 17 at device 3.0 on pci6 ath0: [ITHREAD] ath0: AR9160 mac 64.1 RF5133 phy 11.0 .... ath0: bb hang detected (0x80), reseting wlan0: link state changed to DOWN bfe0: link state changed to DOWN lagg0: link state changed to DOWN wlan0: link state changed to UP lagg0: link state changed to UP ath0: bb hang detected (0x80), reseting ath0: bb hang detected (0x80) wlan0: link state changed to DOWN lagg0: link state changed to DOWN wlan0: link state changed to UP lagg0: link state changed to UP ath0: bb hang detected (0x80), reseting wlan0: link state changed to DOWN lagg0: link state changed to DOWN wlan0: link state changed to UP lagg0: link state changed to UP ath0: bb hang detected (0x1), reseting ath0: bb hang detected (0x1) ath0: bb hang detected (0x1) iperf: ~> iperf -i 1 -t 10 -c 192.168.10.1 ------------------------------------------------------------ Client connecting to 192.168.10.1, TCP port 5001 TCP window size: 32.5 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.10.114 port 60096 connected with 192.168.10.1 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0- 1.0 sec 952 KBytes 7.80 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 1.0- 2.0 sec 712 KBytes 5.83 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 2.0- 3.0 sec 504 KBytes 4.13 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 3.0- 4.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 4.0- 5.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 5.0- 6.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 6.0- 7.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 7.0- 8.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 8.0- 9.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 9.0-10.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 10.0-11.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 11.0-12.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 12.0-13.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 13.0-14.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 14.0-15.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 15.0-16.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 16.0-17.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 17.0-18.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 18.0-19.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 19.0-20.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 20.0-21.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 21.0-22.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 22.0-23.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 23.0-24.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 24.0-25.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 25.0-26.0 sec 0.00 Bytes 0.00 bits/sec [ ID] Interval Transfer Bandwidth [ 3] 0.0-26.1 sec 2.12 MBytes 683 Kbits/secReceived on Wed Jun 03 2009 - 05:19:14 UTC
