    Hey guys I'm a bit of a networking noob so I'm wondering if this setup I have will work in getting all my computers to share our home internet...

    Basically my current setup in my basement this:

    ethernet cable modem
    Wired DLink Router---------->main desktop+2nd desktop

    Pretty standard...But now we want a laptop and another desktop on our top floor because someone else moved in. LUCKILY before we finished the basement I had another ethernet cable going from the router to the Wii on the main floor. We don't play that anymore so I was wondering if it was possible to buy a wireless router for the main floor, connect it wired to the basement router, and than use it wirelessly so that it extends to the top floor? Meanwhile, the router in the basement still connects to the two computers? It'd look like this.

    basement floor
    Wired router---------->main desktop+2nd desktop
    Main floor/ground floor
    wireless router
    second floor
    wirelessly connect to----->laptop+ 3rd desktop (will have to install pci card)

    so yeah, does it work that way?

    Looks like it shouild work.

    You would want the 2nd router as close as possible to the computers on the second flour to minimize any possible interference or signal blockage.

    If you want everything to be on the same network ...

    JohnWill's procedure (Aug. 30, 2008) for configuring a secondary router as a switch and, optionally, wireless access point follows.

    Connecting two (or more) SOHO broadband routers together.

    Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

    Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses through, I'd assign the secondary router as it's IP address, for another router, etc.

    Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

    Disable the DHCP server in the secondary router.

    Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

    Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. [You will not need a cross-over cable if one of the "routers" is a computer.] Leave the WAN port unconnected!

    This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

    For reference, here's a link to a Typical example config using a Netgear router

    Hello and thanks for the replies! Yes, I'm pretty sure range or interference won't be too much an issue, it'll just be one floor directly below, which is why I'm glad I had the wii there or putting it in the basement probably would've been much worse.

    I'm looking @ bestbuy for wireless routers right now, what's with n and g? N seems generally more expensive, how about something like this


    Is there an issue if my wired rouer is dlink and that one is linksys?

    If I log into right now for my dlink, I see these settings:

    IP Address
    Subnet Mask
    DHCP Server

    So I assume for setting the wireless router up, as you and the link said we just to turn off dhcp, and change the new address to / on that router, and this one stays the same?
