iwn0 firmware errors

Edd Barrett
Hi,

I have just upgraded from a thinkpad x60s to an x61s.

The machine came with an iwn wireless card (no suprise really).

After installing the firmware with fw_update, you can start using the
card but very shortly start to see firmware errors. Once I managed to
get an address via DHCP, but that is about as much as I can achieve.

Probably not a huge amount we can do if the firmware is buggy, but worth
mentioning anyway. In the meantime I am using a usb urtwn.


Dmesg follows:

Hi,

i was using a x61s until a month ago. I had these errors too, but only with
certain wifi networks (specifically 2 events with 30+ access points and 1000+
wifi users) using cisco ap's. I never saw these errors somewhere else.

i can find out which cisco access points were used if someone is interested.

/Benno

Hmm. I am seeing the error connecting to a soekris I set up myself. I am
the only client on this. It has a ral card in hostap mode.

It may be related to power saving? Pure speculation ofcourse -- I know
nothing about how these devices work internally.

I also have issues with iwn on my SL510, although only when stressing
the network (and not reliably). Sample:

This occurs with a multitude of APs, so I'm not sure if it's the same
issue. I have the latest firmware, iwn-firmware-5.6p0.
