Wireless issues for everyone in osx lion?

i've been having so many issues with wireless after i installed a upgrade on my mid 2010 27 inch imac i was gonna revert back 2 snow leapord but my orignal restore disc from apple were scratched beyond repair i found out it was from inserting the disc on the side and it hit the metal part so i had no way 2 revert so i burned a osx lion dvd from the store and figured since i had alot of apps maybe if i did a fresh install or a reformat that the wirless issue would go away i did read online about lots of people having the same issue and i did all the tricks steps nothing realy worked even on a fresh install now is it possible that i can order orignal restore disc's from mac since i would like 2 still use ppc apps including mini moog plugins wich are ppc only i think that osx lion is a great os but since i'm on wireless i dont realy wanna deal with coming back a day later finding out my work is not uploaded... if anyone can point me in the direction 2 order oringal factory disc's for my imac that would be great also if i cant order my discs's i'll be waiting for the next patch
