I'm not very computer literate so please bear with me. I have a computer that was built by a friend of a friend and always worked beautifully. I have wireless and a secured network. All of a sudden my computer won't connect to my network, it either stays in the "acquiring network address" phase or says connected but "limited or no connectivity". It will however connect to a neighbors unsecured network with no problem. Both of my roommates have no problems connecting to our secured wireless network. Any help would be greatly appreciated as I've tried rebooting EVERYTHING and don't know what else to try.
