Hi, when running ath(4) on -CURRENT/-RELENG_6 as client and hostap on FreeBSD-5 on another box, you will notice that the box locks up (it's stuck in a busy loop inside the kernel somewhere, if I'm lucky I can get enough cpu-time to press the reboot-kombo). I've described this problem already in my earlier mails. Today I tried to run the hostap box on FreeBSD-6. The problem still exists, but the client seems to recover from the lock after a few seconds and I can get some information out of it. The connection cannot be established once after the short lock has happened and any try to ifconfig down/up, will lock up the client for another few seconds. I could start athstats after the client recovered from the lock-situation: 3 beacon miss interrupts 22 mib overflow interrupts 62 tx management frames 180 tx frames discarded prior to association 6 tx failed 'cuz too many retries 69 long on-chip tx retries 55 tx frames with no ack marked 96 tx frames with short preamble 3 periodic calibrations avg recv rssi: 30 1 switched default/rx antenna Antenna profile: [1] tx 101 rx 0 [2] tx 0 rx 70 The value of "tx frames discarded prior to association" several times a minute. The antenna profiles change sometimes, but everything else does not change, if you run athstats multiple times. I hope it helps to investigate the problem. Client: Thinkpad R40 with Netgear WG511T PCMCIA. HostAP: Sempron 2200+, Asrock K7VT4A+, Netgear WG311T PCI. Martin
