Ahhh... i am a total noob when it comes to these computer things...so i am not sure which one to download.
By the way, this is my wireless adapter, i think i might need to update that too, so if anyone can, can they please help me find this?
Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller(NDIS6.20)
Been trying to find it, but no luck D:.
