I heard somewhere that all modern motherboards have Wifi built in, but I'm not sure if that is true. Basically, I am wondering if the ASUS P8Z77-V LK will let you connect to Wifi networks to use the Internet. I don't have Ethernet cables on the upper floor of my house, where the computer will be.
If it doesn't, is there a device that would allow you to? I know there are USB ones, but are there like PCI-e cards or something?
