modprobe error, please help!!


Hi guys! This is the third forum I post this to. I know I know, I should take the time to get to know the community, but that is a bit difficult when I can't use my computer properly until I got this working...

I have a Samsung x05 laptop running Yoper. The internal NIC is working great, but I really need the wlan card working. I've dowloaded and installed (make etc) the ipw2100 drivers, but when I do a modprobe I get:

root@yos lasse # modprobe ipw2100
WARNING: Error inserting ieee80211_crypt (/lib/modules/2.6.8.1-3/kernel/drivers/net/wireless/ipw2100/ieee80211_crypt.ko): Invalid module format
WARNING: Error inserting ieee80211 (/lib/modules/2.6.8.1-3/kernel/drivers/net/wireless/ipw2100/ieee80211.ko): Invalid module format

Any ideas please? I've been using linux from time to time through the years, but this time I'm really motivated to stick with it if I can get my WLAN and ACPI working properly...

And hi btw

There is a possible clue on the project FAQ:

http://ipw2100.sourceforge.net/faq.php#qa_1_9

(from Pierre Ossman) "If you are using fedora's kernel-sourcecode package then it fails because of different module versions (the kernel checks that the modules are compiled for the running kernel). Fedora adds the string 'custom' to the version id. You can see this if you do a dmesg.

To fix this you have to change /usr/src/linux-/Makefile. Remove the 'custom'-bit and it should work."

If you google for

linux ipw2100 "invalid module format"

there are a few more reports concerning some other distros.

What version of Yoper are you using?
I know with the new 2.1 you will need to add the following into your /etc/rc.d/rc.sysinit

#Load the acpi modules; fan, thermal, ac, battery, button
modprobe battery
modprobe ac
modprobe fan
modprobe thermal
modprobe button

the acpi should be working fine (everything was stock compiled as a modules) unless you have some really funky dt* table settings that are out of wack (prob not if that Samsung is a new machine)

Also what wifi card are you using? I don't know what those drivers are working for (could be 1/2 doz cards really) If you can tell not only the card manufactor but also what chipset it is based off of that will help. I use a Netgear 511 802.11g card and it works under with a modprobe prism54 (well should just haven't had time to get near an ap and get going).

Ok, this is good info!

I looked a bit into the Makefile, but read a little about apt-get and found that installing a new kernel was real easy. Then I found that my kernel-sources installation was 2.6.8-7 while my running kernel was 2.6.8-7. So I did apt-get install kernel#2.6.8-7. The apt-get system really impressed me at this point, because when it was done it told me to reboot, and 2 minutes later I was up and running with a new kernel!

Then I ran make and make install on the ipw2100 again, and the modprobe went without a hitch!

Now though it seems as though both my wlan card and internal nic is listed as eth0 when I do ifconfig and iwconfig, even though the network-script is named wlan0 for the wlan card and eth0 for the internal nic...

Why is this? I renamed the eth1 file to wlan0, and there's no reference to the wlancard in the eth0 file...

It's 2.1, and the Samsung is pretty new, but I've read it's got a fuc*** up dsdt table. Will look into this when I get my Wlan working!

It's the Intel Pro Wireless LAN 2100 adapter that is standard in the Centrino chipset, read somewhere that the driver should work flawless on this system.

Appreciate the help guys!

Oh, and one more thing, ifup is an unknown command on my system, how is this??

Sorry, I don't know much about configuring wireless networking. If you have compiled the driver from source I would think the source package should include some sort of startup script which runs iwconfig and ifconfig to set up the interface, at least to test things.

On a Debian system ifup is used to bring up a network interface according to definitions in the /etc/network/interfaces file. Maybe this is a distribution specific thing. It sounds like you may have a different setup, with startup scripts named after interfaces???

Aaaah, right now I cant get the internal NIC to work either, so I have to reboot into XP to search the net...boring! But Yoper is Debian based, so I think it should be pretty similar. Unfortunately, the Yoper forum hasnt proved to be very helpful yet, but I guess they're just late sleepers or something

I'll check out the network interfaces file...
