After NVIDIA driver installation, wireless module not found?


I recently install FC5 on my hp dv5000t with little problems and got my wireless card working following the wireless instructions found on this website:

http://statgen.ncsu.edu/~jdstarme/fc5_on_t60.txt

After that my wireless was working fine. Then I followed these instructions:

http://www.fedorafaq.org/#nvidia

And it now reconizes my graphics card. My problem is when i do

/sbin/modprobe ipw3945

it says module does not exsist. I think my problem is I updated my kernel to smp when I installed my graphics drivers, and the wireless drivers were installed when my kernel was without the smp on the end.

Any ideas on how I can find out where my wireless module went?

Thanks.

If you rebuilt your kernel you will have to reinstall the wireless driver, and any other drivers that are not part of the kernel proper...Nothing to do with SMP.

I tried reinstalling the wireless drivers, but that didn't help either.

When I installed the NVIDIA drivers it rebuilt my kernel? Where did the wireless module go then?

OK I got it working again after I installed the new kernel modules, but now when I load the wireless module, my keyboard stops working...

right after I do

/sbin/modprobe ipw3945
/sbin/ipw3945d

I cannot enter anything using my keyboard in any window...

edit- My cpu usage also goes up to 100% but I cant find the process that it using it. It wont shutdown unless I hold down the powerbutton to turn it off.

Any idea what could be causing this weird problem?

That's what you said => "I think my problem is I updated my kernel to smp when I installed my graphics drivers"
Did you rebuild it or not?

Your kernel modules are in /lib/modules/<kernelversion>
If you rebuild and install the same kernel version it will overwrite the old ones.
If you rebuild and install a different kernel version then it will use /lib/modules/<new-version>

/sbin/ipw3945d
You have just started a daemon process. It will take over your terminal.
Try ctrl-c
Then try '/sbin/ipw3945d &' which will run it in the background.

Hmm should this daemon process be that resource intensive? When I did this before the graphic driver installation it only took a second or so and it was done. It did not take over the terminal like it seems to be doing now.

Why do you say it is resource intensive? It just runs in the background is all. This is not your module it is a userspace daemon that the driver needs to function properly...

Have you read this?:
http://ipw3945.sourceforge.net/

The reason I say this is because after I do

/sbin/ipw3945d

According to the gnome system monitor, my processor use goes to 100%. CTRL-C does nothing in that terminal, its as though my keyboard stops working. No new programs will open after, and any other terminals i have open the keyboard will not respond in them either.

Pretty much after I do /sbin/ipw3945d I have to manually restart my system or it will just stay at 100% usage, no programs will open, and its unuseable.

Well I did a yum remove the packages, then yum install them again. This time just after I typed in

/sbin/ipw3945d

Everything seemed to be going fine, untill I began to type in ifconfig. I hit i and the terminal started to act as though I had held down the i key, entering a steady stream of i's into my terminal. CTRL-C did nothing to stop the contious I's and nothing responded on my keyboard. I had to again force shutdown the computer.

I have done this about three times now, same things happening.

The only thing that I did that might have effected it is going from 2.6.16-1.2174_FC5smp to 2.6.17-1.2187_FC5smp when I installed the graphics drivers. It seems the newer daemon doesn't work. Is there any way I can revert it back to the way it was before without reinstalling FC5?

Any ideas?

Hi.

Sorry, you do seem to be having a great deal of problems with this.

The keyboard problem, does it only affect the console you are running '/sbin/ipw3945d' in? Can you open another term and use it fine? I am trying to see if it is caused by the command, or if it is an unrelated keyboard driver issue. If you can get another term open then it may help to post the results of 'ps aux' so we can see if processes are getting hung.

Have you tried using ctrl-alt-backspace instead? That should stop the X server. If you have a display manager running (GDM, KDM) then it should start again automatically.

2.6.16-1.2174_FC5smp
Not familiar with the hp dv5000t, does it in fact have dual-cores or 2 CPUs? If you are using a SMP kernel on a single CPU system it shouldn't cause any problems but you never know.

Thanks for hanging in there with me bulliver.

"The keyboard problem, does it only affect the console you are running '/sbin/ipw3945d' in? Can you open another term and use it fine?

The keyboard works fine untill I enter

/sbin/ipw3945d

into the terminal. Once I do that, the keyboard will not enter any text on any program I have open. This is when my cpu usage goes to max, and won't let me open any new programs (using my mouse). If I had programs open, my keyboard does not work with those. After I enter the command It will not allow me to open any other programs.

Yes my cpu is a core duo T2250(dual core processor), so I'm pretty sure I should be using the smp.

Sorry to hear that.

If you ever decide to try again I would follow these instruction exactly:
http://ipw3945.sourceforge.net/INSTALL

rather than from that link you posted. There are quite a lot of prerequisites that must be satisfied before you can even try using the driver. It says the driver was engineered by Intel themselves so there is no reason it shouldn't work.

Also, try getting help at IRC channel #ipw2100 on irc.freenode.org.
Those folks will at least have the same wireless card so they will be able to give you better help than me
