xircom nic itch (drops ip)

[Stig Brautaset]

Hi all,

My pcmcia network card drops its ip from time to time. This happens
frequently enough for it to be rather annoying, but not frequently to be
really annoying. It seems to happen when there is no traffic through
the link (based on the fact that I cannot ever remember it happening
while I was on irc ;).

When the problem first occurs, it seems to occur several times quickly
one after another a few times, then the problem goes away. There is no
problem with suspend/resume, however.

I am unable to find anything in any of the logs, and bugs.debian.org
does not list any related bugs for the pcmcia-cs or hotplug scripts.

The card is a Xircom Cardbus 10/100 NIC (CBEM56G-100), and it use the
kernel's xircom_cb module. I used to use the module in the pcmcia_cs
package before, but I can't remember whether it was any better then (I
don't think it was though).

Are you using dhcp on that interface? If so, what happens to the dhcp 
client daemon when the interface 'loses' the ip? Is it logging anything?
Is it dying?

If you're not using dhcp, I'm a little stumped..

You could try to use the xircom_tulip_cb module instead, and see if it
solves the problem. I don't think it will, but who knows.

Despite what Configure.help says, xircom_tulip_cb is actually better
than xircom_cb. The latter should only be used if xircom_tulip_cb
has problems -- I haven't heard of any recently, but I do want to hear
about them if they still exist.

Hi Ion,

Thanks for the answer :)

I am using dhcp from time to time, but the card drops its ip when it is
allocated statically as well :(

However, it *does* seem to drop its ip more frequently if I am using
dhcp, or between usage of  dhcp and a reboot (I normally just use
suspend) so this might be the case. I will monitor this a bit closer...

Can't seem to load that module I'm afraid..

Thank you very much for your help anyway.
