RAID is an acronym meaning âRedundant Array of Independent Disksâ. As the name implies, RAID creates an array of multiple hard disks in order to provide redundancy. An array simply means a collection of drives that are presented to the operating system as a single logical device.
Fn + F2 didn't work, and my computer doesn't have a physical switch on the outside, which is why I asked here. â lowerkey Apr 29 '12 at 18:45. sometimes this can be solved by booting into windows, enabling your wireless (Fn+F2) before booting into ubuntu.
If the hardware switch is permanently off the only solution is to fix the switch. This will obviously require a bit of surgery on the laptop. You may not be so adventurous (and there is some risk in this), which leaves two choices: 1. find a repair shop to fix the switch. 2. use a USB wifi dongle. Apr 20, 2013, 5:41 PM.
