Hi, All! I am doing a wireless experiment. The testbed have 7 nodes. Each node has two atheros cars, one in AP mode and the other in IBSS mode. There are something wrong with the IBSS mode cards: sometimes the card stops to work, it won't transmit any packet unless I reload the driver. This problem can happen on every node, so I guess it's not the hardware bug. I use Linux FC 4, kernel version: 2.6.11-1.1369_FC4. The cards is TP-link TL-WN 650G, support 802.11b/g, here is te lspci output. 01:00.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01) 01:04.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01) The madwifi I use is revision 1794, downloaded from SVN in Nov, 8th. The driver load info is in attached file: driverinfo. When error occured, I turned on all debug info. and get a lot of: ath_intr: status 0x5009 ath_rx_tasklet R (d6a66570 16a66570) 16a665a0 111fb020 00000000 00000c60 104d8000 44a71911 ! ath_intr: status 0x1009 ath_rx_tasklet R (d6a665a0 16a665a0) 16a665d0 0e592020 00000000 00000c60 116d811e 5d340003 * (see http://liuchao001.googlepages.com/wrong1 for the whole log file) I noticed the README document in madwifi said "Ad-hoc mode is broken; symptoms are intermittent operation". Since I have this 7-node ad-hoc testbed, I just started to read the madwif source and hope I can do some contribution for madwifi ad-hoc mode. |
