On wheezy (3.2 kernel and 3.12 from backports) I was not able to get the iwl3945 or any other wifi card from the T6*/X6*/X6*t series to work correctly, although they worked under 2.6 kernel. The newer models from T500 upward seem to work, but only 5 GHZ, not 2.4 GHz.

Hello
Here is the short question:
Did anybody successfully compile a kernel >= 3.7, within trinity and got the wifi to work for the machines mentioned above??
Rationale and longer story.
I am running a X60 and an X200, both with trinity/Kubuntu 10.04 (I know it is outdated but I have my reasons) and wifi works without any problems.
I replaced in both machines my HHD with a SSD and reinstalled Kubuntu 10.04 again, using the jfs file system. I am very pleased with the results.
However after the installation I found out that on the long time run I should use trim, which was not supported for jfs in the 2.6.32-37 kernel. I could upgrade the kernel via the backport releases but these backport releases did not include the kernel 3.7, which was the first kernel to support TRIM for jfs. So I should reinstall Kubuntu using either ext4 or xfs or compile a new kernel.
So, I downloaded the 3.7.0 kernel on my X200 and run set of commands which I have attached belows.
Now the relevant wifi intel driver 3945 for the X60s and the PRO/Wireless 5100 for the X200s seem to be compiled.
However when I boot the new kernel and run the ifconfig command there is only the wired card detected but no wlan0 or eth0 device is found.
I am puzzled: if I boot the 2.6.32-37 kernel I have wifi support but not with the 3.7 kernel.
What should I do?
I can run sudo ifconfig wlan0 up, but knetworkmanager and wicd do not find the wireless card.
Any help is strongly appreciated
Thanks

I made lsmod on my X60 machine once with the new 3.7 kernel once with my old 2.6.32 kernel. The difference is huge in my X60 machine one line is particular interesting, namely iwlcore 106661 1 iwl3945
this line is missing for the lsmod for the 3.7.0 kernel indeed this module does not exist. What do I miss.
I don't hope I have to recompile the kernel? Can somebody help me how to get the module loaded
thanks

Commands used to compile the kernel: sudo make menuconfig
sudo make sudo make modules sudo make modules_install
make INSTALL_MOD_STRIP=1 modules_install sudo make install sudo update-initramfs -u -k 3.7.0
cd /boot/grup
sudo cp grub.cfg grub-org.cfg
su
grub-mkconfig > /boot/grub/grub.cfg
sudo update-grub
