Re: Wireless network problem after upgrade to 8.04

G'day there Paul,

PRO/Wireless 3945ABG wireless network card and connected reliably
without problem.


I have that device working in a fresh install of 8.04, so lets see if
you might have some old settings running that are causing trouble.

That wouldn't surprise me but the install told me that it was
replacing necessary files. I assumed the old settings would be amongst
those.

# sudo /sbin/lsmod

it lists out loaded kernel modules. If you don't see iwl3945 in there,
it means it is failing. Could try to load manually

# sudo /sbin/modprobe iwl3945

Wasn't necessary, it showed up.
Then run

# dmesg

to see if it started.

ken@Epona:~$ sudo dmesg | grep iwl

ken@Epona:~$

I guess it's running.

Here's a very important thing to know:

The LED light for the wireless device DOES NOT turn on, even if it is working!

I've never looked. I figured that if it wasn't working then I'd know
without checking the light =).

So in the terminal again, make sure the network-manager is running

# /etc/init.d/network-manager restart

I don't have a 'network-manager' there, only a 'networking' entry.
Is that the same?

ken@Epona:/etc/init.d$ ls net*
networking
ken@Epona:/etc/init.d$

and then

# nm-applet

should make sure the network-manager applet is running. Try to use
that to manage your connection.

Yep. The applet is in the top bar and I've used it to set what I
thought were the correct settings as previous, but no success.

IF you want the LED light to come on, you can get it by installing the
backported linux kernel module.

Not a priority <g>.

There is also an updated version of the Network Manager available.
Look in archives for last week for an email I posted in this list
called "Head's up for people with Wireless in Harty, especially Intel
Wireless IPW adapters". That points at the links.

Now that I'm in Windoze I can have a look for it. Dunno it it will
be more suitable than the standard installation, but it can't hurt.

If it's any use, this is the result of stopping & starting the
init.d/networking command:

It make little sense to me, except to indicate that something's not
working as I wish it to.

Thanks for taking the time to help,
It's much appreciated.
