Basically, in my house, we have 5 computers. I have my battle station, and my satellite station (aka. laptop). My mom has her desktop station and a laptop for work. My father has got a laptop.
Initially when we got internet, it was only in my mom's office. This didn't fly with me, especially when broadband came along. So I bought a wired router and wired cat5 cable into 4 rooms. When I feel like going on my laptop, I almost certainly want to be online. But it is also almost certain that one of my parents are using the one remaining cat5 outlet. After a year of fighting over who gets to use the outlet, I bought a wireless router. So I have it, and I now have time to set it up. Is it possible to get the following configuration? Well, it pretty much has to be, because there is no alternative.
Modem --> Wired router ---> supplying internet to comps via cat5e
---> Wireless router ---> supplying internet via wifi to laptops as required
So the thing is, I want to keep my wired and wireless router. Three of the wired router's outputs are going to comps wired into my network, the one remaining output will be the input of the wireless.
