Best Guess:

By not having the wireless (USB dongle, I am assuming) when installing, 
the system did not put the USB human interface drivers in the initrd file.

You can easily run dracut to correct that.

You may want to substitute values in my example just to be sure ...

# cd /boot
# dracut --force initramfs-`uname -r`.img  `uname -r`

Next time you reboot you should be fine, or next time you get a kernel 
update from yum it will also get 'fixed' as long as the wireless 
keyboard is plugged in when you do it.

Good Luck!
