Router

As the resident IT support at home (even though both parents work in IT....they refuse to do IT at home), I have the joy of installing routers. Now, our house has a perfectly functional wireless router downstairs, but they wanted another switch upstairs for their desktops (and dad's work laptop). The other weekend, my dad went and got another identical router, IDENTICAL to the one we have downstairs. Most routers can act as a switch as long as you plug in a lan line from the existing router into one of its lan ports (not the WAN port!). Well, except we have an identical router, which shares the same factory default IP, subnet mask...etc as the original. Joy to the world. Take a guess at how well the new router acting as a switch works.
