Plain english replies, please. Newbie here. I have a small home network, consisting of my computer which is wired to router and my wife's computer which is wirelessly connected. Just bought a new laptop with wi-fi. Worked fine until today. (I just installed free VOIP program from Netzero, if that makes a difference.) Laptop screen now says I need a new IP address. Also, when I turned it on, it gave similar IP error message to my wife's computer. 1.Is the because of netzero VOIP? 2. How do I establish a new IP address on my laptop? Or my wife's? Thank you!
