I've been trying new versions of the iwlwifi driver for a while now,
and while the situation for most folks seems to be improving, I'm not
having much luck. I'm running 0.0.32 patched into the latest Fedora
kernel (which is basically 2.6.21.5 plus the current wireless-dev
tree). This version is improved over some previous versions which
would periodically freeze the machine for a few seconds, but I can
still see no networks or even do a scan. (iwlist scan just hangs for
about 15 seconds.) I'm using version 2.14.3 of the microcode.
An interesting note is that the ipw3945 driver never worked on this
hardware either. It manages to at least see networks, but won't
associate. Unfortunately it does work fine under that other OS.
The machine is a Sony Vaio TXN17P; lspci shows:
01:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG
Network Connection (rev 02)
Here are the iwl3945-related kernel messages:
