Bug 980055

+++ This bug was initially created as a clone of Bug #903668 +++

Cloned because the suggested workaround (rename iwlwifi*-5.ucode) does not seem to have an effect with the laptop I am using and the version of Fedora is no longer 18 but now 19.

The bug description still applies.

Hardware info I get:

Note how slow the firmwarerequests appear!

The firmware-files exist in /usr/lib/firmware aswell as via symlink in /lib/firmware:

$ ls -l /usr/lib/firmware/iwlwifi-1000* /lib/firmware/iwlwifi-1000*

Finally the lshw output related to network:

Description of problem:
The firmware fails to load on boot, which means that the Wireless adaptor is marked as 'unavailable' and thus unusable.

Reported here as well http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2314
However, this was reported a year and a half ago and has still not been fixed.

Version-Release number of selected component (if applicable):
Intel Centrino-N 1000 Wireless Adaptor.

How reproducible:
Every time

Steps to Reproduce:
1. Boot the laptop
2. Error messages as wireless fails to intialise
  
Actual results:
Wireless does not work.

Expected results:
Wireless should be working. Works on Windows (and older kernel versions).

Additional info:
This used to work before newer kernel versions (around when the 3.0.0-1 kernel came in) and has not worked since. A previous workaround was to use the old v3 code, although iwlagn is not present in Fedora 18 and therefore this workaround does not work currently. Disabling the 'N' part was also suggested although this hasn't worked for me.

The driver name changed from iwlagn to iwlwifi.  I'm not sure what workaround you mean, but maybe that helps?

Anyway, I would need to see the output of dmesg to have any idea what the problem is with the firmware loading.  Please run 'dmesg' and attach the output from that to this bug...thanks!

Ok so the workaround of reverting to the old v3 code does still work, by doing something like 

sudo mv /lib/firmware/iwlwifi-1000-5.ucode /lib/firmware/iwlwifi-1000-5.ucode.backup

However, this has been a temporary fix for the past nearly year and a half (see http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2314 which I reported on the Intel bugzilla).

Firmware errors on load with iwlwifi-1000-5...Johannes, should we consider changing the driver to only ask for version 3?
