Bug Description
I was surprised to find my wifi not work after upgrading to Maverick as it had worked just fine in lucid. The network-manager would show wireless network disabled and 'Enable Wireless' shown by right clicking the network-manager icon was disabled/greyed out.
So I did some debugging and found the following:
1. The wifi light on my laptop never lit up anymore
2. Bluetooth appears to work now (yay!) as toggling the physical rf kill switch would show the device coming up and down in dmesg. However, nothing in there about the wifi device.
3. Removing the 'dell-laptop' kernel module made my wifi work (yay!)
4. With 'dell-laptop' installed, 'rfkill list' shows that the wifi is hard blocked.
5. With 'dell-laptop' removed, 'rfkill list' shows nothing.
6. The physical rfkill switch works just fine with 'dell-laptop' removed.
So clearly there is a (serious) regression occurring here. I'm unsure if 'dell-laptop' was getting loaded in lucid but I'll boot up a lucid live-cd when I get a chance to check.

I had the same issue (resolved the same way) in Lucid with a dell vostro 3300
