...wireless network? I just bought a LinkSys wireless router. The wireless adapter on my computer connected succesfully to the router but it's now asking me for "Key1:" where do I find that?

You need to concoct a key yourself (e.g. 1234567811)(. This same key would be used at each of your wireless clients (i.e. laptops or desktops). When you connect your laptop to this router, microsoft windows would enquire you for the key (this is a security feature)
