How to share wifi using wifi hotspot

view story

http://forums.fedoraforum.org – Hi, Is there any application in fedora to share wifi using a wifi hotspot like Connectify for windows? I know that this sounds weird but I cannot access the original wifi network because of mac id issues in our college. They give internet access only for those who register their mac id and that too only one mac id per student. Please let me know if any application is available for Fedora 19. I am using Lenovo G460. Thanks, KM (HowTos)
