I'm trying to reinstall OS X lion by using the Recovery HD. I know that is a last resort type thing, but that is where im at right now. When I sign into my wifi with my WEP key it then asks me this: "airportd wants to use the "login" keychain." "Please enter the keychain password." I have tried any password that I knew of and none of them worked. I have no idea what to do. Any ideas?
