missing wireless after upgrading from F18 to F19

view story

http://forums.fedoraforum.org – ]I upgraded F18 to F19 using fedup network option on a dual boot Windows/Fedora laptop. After overcoming a few glitches related to grub.cfg, I am able to login. One remaining issue, is a missing wireless driver. Somehow, a directory wireless present in /usr/lib/modules/3.9.6-200.fc18.x86_64/kernel/drivers/net is absent in /usr/lib/modules/3.9.5-301.fc19.x86_64/kernel/drivers/net/ directory. How do I load ath5k module? Is the fedup version of kernel 3.9.5-301.fc19.x86_64 incomplete or there is other way to load a module with driver for Atheros AR242x / AR542x wireless adapter? I appreciate (HowTos)
