Subject:   Cisco Aironet PCI card - Working but Flaky

Hi all,

I've tried the Cisco wireless card and it works to a point. I've used
ifconfig to configure the an0 device, and it manages to join the
network. 

However, I'm having problems with the speed.

When I first tried using the if_an.ko module, I got the following in
my messages file:

Jan  9 18:32:11 ford /kernel: an0: <Cisco Aironet 350 Series> port
0x9400-0x943f,0x9000-0x907f mem 0xde000000-0xde00007f irq 10 at device
13.0 on pci0
Jan  9 18:32:11 ford /kernel: an0: Ethernet address: 00:40:96:5a:17:97
Jan  9 18:32:11 ford /kernel: sio1: configured irq 3 not in bitmap of
probed irqs 0

The sio1 message happened every time I loaded the module, even though
I don't have a com2 port (disabled in bios).

I then compiled the an driver into the kernel and tried again. The
sio1 message went away, but I was still having horrifically slow ping
times to another machine on the network (anywhere from 400ms to
1000ms). I was also getting frequent an0: device timeout messages and
I would have to reinit the device before it would work again. I
checked IRQ's and it was sharing an IRQ with my USB device.

I then installed my ethernet card back into the system and now the
Aironet gets an IRQ of 12 (shared with sound card). Ping times and
packet loss are now _marginally_ better, but I'm still seeing anywhere
between 32 and 243 ms ping response times
64 bytes from 192.168.10.1: icmp_seq=4 ttl=64 time=61.749 ms
64 bytes from 192.168.10.1: icmp_seq=5 ttl=64 time=243.926 ms
64 bytes from 192.168.10.1: icmp_seq=6 ttl=64 time=16.505 ms
64 bytes from 192.168.10.1: icmp_seq=7 ttl=64 time=83.430 ms

I've moved these machines quite close together and abaout a room apart
yet it makes no difference.

Any advice on troubleshooting this would be _much_ appreciated.

Regards,
