Hardware switch on ?
Also, you might need a reboot or try

su
modprobe wl

IIRC right

Poifect! Thanks Nokia! Your cellphones are alright!

Hmm. Got the same problem here after updating the kernel.

This is what I have:

[root@leonidas ~]# uname -r
2.6.30.9-90.fc11.x86_64
[root@leonidas ~]# rpm -qa | grep iwl3945
iwl3945-firmware-15.32.2.9-1.fc11.noarch

I have the (bad) habit of deleting the previous kernel after installing a new one.
So can't switch back here.

If i do "ifconfig" wlan0 won't be there. I can see that NetworkManager detects the wifi switch on/off though.

modprobe iwl3945 didn't work

Any ideas?

I think the topic has moved from broadcom-wl to iwl3945.

Maybe it's already loaded and something else is wrong. Check with lsmod | sort.

Hi!

I guess the modprobe did work.

Next time I turned on the laptop, the wifi led started blinking and voila, got internet.

Good. But I don't know about modprobe doing it. I have always believed that the manual modprobe command will load a kernel module but not configure anything that will survive a reboot (I'm willing to be taught something new though). It's been my impression that sometimes we can modprobe and restart services and whatever without success, but then a reboot can sometimes work wonders. And this is not the first time I have read about that happening regarding wireless.

The strange thing to me was the report on iwl3945. I ran it on all the kernels in F7->F11 (albeit on i386 only due to CPU limitation) and never had a glitch. Modprobe was only supposed to load a driver but perhaps ifup was needed or a hardware off/on switch to make it visible to NM.

Hello blueboy,

Well, the kmods for that kernel are in the RPM Fusion repo. So do all the usual things.

1. Review the installed packages. They should all make sense...

   rpm -qa | grep -e kernel -e kmod-wl -e broadcom-wl | sort

2. Review the loaded modules. As you know, wl should be there and conflicting modules should not be there...

   lsmod | sort

3. Reboot into the previous kernel and check for wireless there (to rule out other parts of the network).

P.S.: I'm not sure your situation was ever really right. You should not have had to add that modprobe command to rc.local. That's usually not necessary to make the wl module load.

Don't want to sound cynical, but F10 will be an an EOL product in a matter of weeks. Therefore no more updates, no more support whatsoever. It's best to backup data and install and install F12. Read this post on Adam Williamson's blog too. http://www.happyassassin.net/2009/11...2-crunch-time/

As I see F12 right now, you should have a hassle free experience installing/running it, and as long as you keep updating it regularly (daily would be best) I don't think you'll have any more problems. And even if you do, you'll have a swift resolution provided you file a bug report.

Thing got solved today after the kmod-wl got updated.

Next time -and even now- you could avoid this complication and spare us the time trying to troubleshoot a non-issue. All you need to do is install akmod-wl package and your much needed driver will be built automagically regardless of the kernel installed. You need rpmfusion nonfree enabled, but I think you already have it.
