Wifi not working

Hi friends,
my laptop is Acer TravelMate 5744z, it has Atheros AR5B125 wireless network adaptor, it was worked fine till yesterday, it was stopped working when i messed up with device manager and uninstalled it along with it's drivers.
After that i have tried updating and installing driver with with my driver cd and other atheros drivers downloaded from internet but there was no luck.
Someone please help me solving this problem.

Agree with DMHolt57 Restore the PC to an earlier point.

Did you mistakenly uninstall/remove any other device from the device manager besides the wireless adapter(s)?

yes , i removed wireless network adapter and broadcom netlink controller, but broadcom netlink controller seems to be ok when i have updated drivers with the driver cd
