My Lenovo T500 notebook has the garden variety Intel PRO/1000 wired ethernet adapter, and also the Intel WiFi Link supported by the iwlagn driver. Imagine my surprise when Lupu 5.01 (booted from CD or flash drive) detected no network adapters at all.

When I boot up Ubuntu 10.04 LTS both cards are detected without a problem.

What the heck is Lupu 5.01 missing?

Well this is very curious. When I run 'modprobe e1000e' it complains

cannot load 'kernel/drivers/net/e1000e/e1000e.ko' - no such file or directory

But the file exists in /lib/modules/2.6.33.2/kernel/drivers/net/e1000e. When I cd to /lib/modules/2.6.33.2 and repeat the modprobe command, it succeeds and the module is loaded.

Running 'depmod -a' fixed it. That's pretty odd. I guess Lupu setup didn't run it for some reason?

Running Puppy linux on Lenovo Thinkpad X201.

In both lupu and wary I could not use my wireless on boot. Dmesg reports:

iwlagn 0000:02:00.0: firmware: requesting iwlwifi-6000-4.ucode
iwlagn 0000:02:00.0: iwlwifi-6000-4.ucode firmware file req failed: -2
iwlagn 0000:02:00.0: Could not read microcode: -2
iwlagn 0000:02:00.0: firmware: requesting iwlwifi-6000-4.ucode
iwlagn 0000:02:00.0: iwlwifi-6000-4.ucode firmware file req failed: -2
iwlagn 0000:02:00.0: Could not read microcode: -2

FIX:

Copy the drivers from ubuntu 10.04, e.g. (I have ubuntu installed on hard drive of same machine at /dev/sda5):

cp /mnt/sda5/lib/firmware/iwlwifi* /lib/firmware/

Then remove the iwlagn module and re-insert.

modprobe -r iwlagn
modprobe -a iwlagn

dmesg is much happier. But to make it actually work to configure wireless, we must

depmod -a

Voila!
