Function F5 (under Windows) should toggle the wireless on and off. Some of the function keys work under Ubuntu but no all. I still have Ethernet and a USB wireless dongle that does the job but I'd still like the have the internal wireless card working.

What does lspci show?  Mine shows:

...
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)
04:00.0 Ethernet controller: Broadcom Limited NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)
...

(this is a Lenovo R500, running CentOS 6)
