I have a netgear router that has four ports available. I have two of the ports being used by desktops hooked directly into it. I have one of my laptops able to connect to it with no problem and then one that won't. The laptop I'm having problems with is a Dell Inspiron 1525. I typed in the correct key and key type into the slots. I know this because it's the same I used for my other laptop. The Dell is running Windows Vista Home Premium and the working laptop is running Vista Business. Any help would be greatly appreciated.
