Hi,

What kernel version are you using? Is this a regression? If so, what was
the last version that worked well?
What if you rmmod the driver and then reload it? Does it make it work again?
What hardware is it exactly? The airo driver supports more than one type
of card.
Are you doing anything special with the card, like running some wifi
monitoring application for instance?

Michal

Is this 340 or a 350?  MiniPCI or PC-Card?  Can you give us the PCI
device numbers (from lspci) or the PC-Card manufacturer and device id
(available from lshal)?

What firmware version as well?  Post the output of the following and
scrub MAC addresses if you like.

cat /proc/driver/aironet/eth0/Status

If we can't determine anything with this, would you be willing to post
your card to a developer so we can diagnose?  I personally have a few
airo 350 cards, both MPCI and PCMCIA, and none of them exhibit this
problem.

I'm using 2.6.21, last version that worked well is something like 2.6.15

Now I get another error while ifdown && ifup again:

Per our IRC conversation, it seems that this problem emerged for you
between 2.6.16 and 2.6.17.  Please try using git-bisect to determine
exactly which patch caused this issue for you.

Thanks,

John

Just before teh network goes down i notice a slowdown, i investigated and i 
discovered
that the card drops big (not _so_ big) packets:

[~]$ ping 192.168.0.2 -c 6 -s 482

This is another weird behaviour: small packets does arrive, big ones are 
corrupt:

This happens pinging different hosts, so that's not an issue with the host macbook-luca,
