    A router passes communications between networks. What do you need to know about them? Tom

    ...(with dif. access info.), will a router allow me to do this? I suppose that depends on what is meant by "(with dif. access info.)". Normally, the router would hold the "access info". The router establishes and maintains a connection between the local network on the inner side of the router and whatever network is one the outer side. The outer side is often expected to provide access to the internet. The router's connection to the outside is generally shared by devices on the inside. But there needs to be much more detail about "(with dif. access info.)" before any useful guess can be made about your situation. Tom

    I think you will find that a router is a device used in woodworking. Cisco are the biggest manufacturer of these, along with Black and Decker.

    Router joins dissimilar networks together. And can serve other purposes depending on what you want to use it for...
