Networking problem

Hello,
i am experiencing difficulties with my computer connection .For some reason my computer cannot find any network connection and it says that it's because i don't have any wirless adapter unstalled .But here is where i don't understand (even more the first time) ,when i access my network adapter i can't clik on the icon "rollback adapter" but can only clik on the icons"disable" "uninstall" and "update"..
I don't how understandable i am but if anybody knows what i'm talking about please help because this is really anowing and i really need to use my computer as quick as possible.
thank you
