What I have found is that on some feisty kernel updates, there weren't the corresponding /sbin/ipw3945d-{KERNEL_VERSION}.
When that happened, I just created a link to the ipw3945d of the previous kernel version and rebooted. That worked for me (Toshiba Satellite A105-S4344). -- wireless card ipw3945 not recognized https://launchpad.net/bugs/90492 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
