Hey, I am running 4.9-STABLE on my new IBM T40, and I just put in a Cisco Aironet MPI350-card, since I have used regular 350 cards with the an driver with excellent results over the last year or so. The problem is, that although the card seems to be identified correctly, and I am able to ifconfig the interface, I am getting a lot of timeouts from the an driver. Performance is very low, and the machine more or less freezes up when the timeouts happen. I have collected a bit of info below: uname -a: FreeBSD narya.staff.tdk.net 4.9-STABLE FreeBSD 4.9-STABLE #5: Mon Feb 23 13:38:28 CET 2004 sonny@narya.staff.tdk.net:/usr/src/sys/compile/NARYA i386 >From dmesg: an0: <Cisco Aironet MPI350> port 0x8000-0x80ff mem 0xc0400000-0xc07fffff, 0xc0200000-0xc0203fff irq 11 at device 2.0 on pci2 an0: got RSSI <-> dBM map an0: Ethernet address: 00:02:8a:dc:90:83 Feb 25 12:19:59 narya /kernel: an0: device timeout Feb 25 12:20:33 narya last message repeated 5 times Feb 25 12:21:33 narya last message repeated 9 times This is the output from a ping (10.253.0.1 is a box on the same network): 64 bytes from 10.253.0.1: icmp_seq=0 ttl=255 time=2.156 ms 64 bytes from 10.253.0.1: icmp_seq=2 ttl=255 time=4758.609 ms 64 bytes from 10.253.0.1: icmp_seq=3 ttl=255 time=3749.048 ms 64 bytes from 10.253.0.1: icmp_seq=4 ttl=255 time=2739.507 ms 64 bytes from 10.253.0.1: icmp_seq=5 ttl=255 time=1729.866 ms 64 bytes from 10.253.0.1: icmp_seq=6 ttl=255 time=998.952 ms 64 bytes from 10.253.0.1: icmp_seq=8 ttl=255 time=4766.989 ms 64 bytes from 10.253.0.1: icmp_seq=9 ttl=255 time=3759.227 ms 64 bytes from 10.253.0.1: icmp_seq=10 ttl=255 time=2749.646 ms 64 bytes from 10.253.0.1: icmp_seq=11 ttl=255 time=1740.125 ms For comparison, here is a ping done from the laptop, but using a different card (with the wi-driver): 64 bytes from 10.253.0.1: icmp_seq=0 ttl=255 time=7.482 ms 64 bytes from 10.253.0.1: icmp_seq=1 ttl=255 time=3.290 ms 64 bytes from 10.253.0.1: icmp_seq=2 ttl=255 time=3.153 ms 64 bytes from 10.253.0.1: icmp_seq=3 ttl=255 time=2.997 ms 64 bytes from 10.253.0.1: icmp_seq=4 ttl=255 time=3.965 ms 64 bytes from 10.253.0.1: icmp_seq=5 ttl=255 time=4.122 ms 64 bytes from 10.253.0.1: icmp_seq=6 ttl=255 time=3.702 ms 64 bytes from 10.253.0.1: icmp_seq=7 ttl=255 time=3.048 ms In short, packet-loss, timeouts and very bad performance with the an-driver - strange, since it works nicely with a regular Cisco-card (AIR-PCM352). Any ideas? I saw somebody mention, that maybe downgrading the firmware on the card would help - although I am willing to find a colleague with a windows-box to do this, I am somewhat perplexed. It does look more like a driver-problem to me - and the suggested firmware (5.0001) is very old indeed. TIA, -- Bye, Sonny! "Respect is fine, but actually I've always wanted to be feared."
