Dell n5110 wireless
I have a Dell Inspiron n5110 laptop running Fedora 16, dual booted with Windows 7 Home edition. Everything works fine except the wireless under Fedora (it runs ok under Windows). The wireless hardware is turned on (Fn-F2), but only the wired network interface shows up in the system settings. lspci looks healthy:
09:00.0 Network controller : Intel Corporation Centrino Wireless-N 1030 [8086:008a] (rev 34)
Subsystem: Intel Corporation Centrino Wireless-N 1030 BGN [8086:5325]
Flags: fast devsel, IRQ 19
Memory at f7e00000 (64-bit, non-prefetchable) [size=8K]
Capabilities: [c8] Power Management version 3
Capabilities: [d0] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [e0] Express Endpoint, MSI 00
Capabilities:  Advanced Error Reporting
Capabilities:  Device Serial Number bc-77-37-ff-ff-b3-cd-01
Kernel modules: iwlwifi
The driver, according to Intel, is in the kernel, so I must just be missing some magic incantation...
Are you able to locate anything related in dmesg? AFAIR, once I had similar symptoms and the reason was either missing or wrong version of firmware. Another time it was an external switch on the backside of the laptop, which I was unaware of. Kernel messages were somehow helpful to locate the issue.
It might help to know what wireless chip you are using.
If you dont know, looking in windows control panel should tell you.
Thanks for the help, all. The problem was solved by installing the missing firmware file. Although Intel says the firmware files are included in the kernel by default, they apparently aren't included in the standard FC16 install. Here's the magic sauce:
# yum install iwl6000g2b-firmware.noarch
