I just got a "new" laptop and I can't get it connected to my network. I connects fine when I connect it by wire but I can't get it to connect to my wireless. It detects the network and a couple others within range. And I can connect to the other ones(probably my neighbors). But when I choose my network it says connected but it does not seem to be able to find an IP address. It says connected but the icon says limited or no connectivity. I have a Linksys router. Any ideas?
