Hello, this is my first post. I will first explain the situation: My router is in the basement where the main computer is. We have three other computers in the house, another downstairs and 2 upstairs. Ethernet cables have been wired throughout the house to all the computers. There are no more ports on my router to be used and even if I did, I do not wish to wire more ethernet cables through the house (let me tell you its such a hassle). Now heres my question: Can I take one of the ethernet connections thatgoes upstairs and have that connection go through a 2nd router? I wish split that connection to connect other devices such as a laptop and a video game system from this router. Is this connection possible? And if so, will I see a speed reduction? I currently have dsl internet and not cable. The downstairs router is an old smc router ( similar to this: http://www.smc.com/index.cfm?event=viewProduct&localeCode=EN_CAN&cid=1&scid=&pid=924) Is it possible to have routers connected in series?
