Mixed Wired & Wireless Home Network

    I have a wired network setup in my house because the layout prevented a
    wireless signal to the most remote computers without multiple boosters.
    There are 4 computers currently on the network. Two computers are in the
    office where the cable modem & 4-port SMC 7004VMC reside. Two cables were
    run to the other end of the house to each of my children's bedrooms to a
    wall socket. Everything works fine. I know I can piggy-back a 2nd wired
    router (SMC 7004 I have laying around) with a crossover adapter attached LAN
    port to LAN port with DHCP disabled in the SMC 7004. Earlier in the year I
    had done this while I was building a 5th computer & temporarily hooked it to
    the network with both routers connected directly together in the same room.
    Now I must move the 2nd computer in the office to the other end of the house
    just across the hallway where my daughter's computer is hooked to the wired
    network at the wall.


    - Would I be able to attach the 2nd router via a LAN port & crossover
    adapter to my daughter's CAT-5 wall plug, turn off DHCP, plug my daughter's
    computer directly into the 2nd router & plug in a WAP to another LAN port
    on the router to network the computer across the hall after adding a
    wireless NIC?

    -Instead of buying a WAP, would it be cheaper or make more sense to buy a
    wireless router equipped with direct LAN ports instead of a WAP? Would both
    the computer connected by cable & the wireless computer be able to access
    the network/internet with DHCP disabled? I do understand that, depending on
    which new wireless router, the interface with the CAT-5 wall plug may be
    different (via WAN or LAN port, with or without a crossover cable).

    Anyway, I am an amateur & probably over-thinking this. Maybe instead of
    asking how to make my solutions work, I should ask how would you experts
    solve this problem.

  2. I'm not 100% sure about the SMC7004 series, but I'm 99.9% sure that you
    don't need a crossover cable because the router LAN ports are
    Should work (and you shouldn't need a crossover cable; see above). The
    2nd router works just as a hub/switch in this case.
    In such a setup, you typically don't want to use the WAN port on the
    wireless router. You'd only want to use the WAN port if you want to
    separate the network into two subnets, with limited access to each other
    (and associated configuration headaches). But connecting the cable from
    the main router to a LAN port of a wireless router works just fine
    (disabling DHCP and other router functions in the wireless router,
    leaving it as a hub/switch and wireless AP). FWIW, this is what I'm
    doing with a Linksys WRT54GL.

    Whether this makes sense financially depends on what you have and what
    you're looking into buying... just add it up :)

    This all started because my company wanted me to set up a separate cable
    line to work at home. He connected a totally separate line to the pedestal
    tap & connected it directly to my computer & downloaded at 15-20Mbs. When I
    insert the SMC7004BR or 7004VBR, the speed drops to between 6 & 7Mbs. These
    routers are 6 years old. Do they go bad? Any way, I purchased a Linksys
    WRT160N to replace the main router. Now I get the full 15-20Mbs over the
    wired network. I installed a wireless card in the computer that will
    eventually be moved & it gets 6-7Mbs about 10 feet away from the router in
    the same room. I appreciate that you confirmed that a wireless router will
    function as a WAP if DHCP is disabled & connected LAN to LAN port. Since the
    signal drops off before the final potential locations that the computer
    needs to be moved to, I will now purchase a 2nd Linksys WRT160N , plug it in
    the wall on the other side of the house, disable DHCP & use it as a WAP. The
    added benefit of doing this is that my daughter can now use her I-Touch all
    the way in her bedroom & the kids have a WII down that end of the house that
    I am told can connect wirelessly to the internet also.
    BTW, the Linksys WRT160N comes with a CD installation guide that walks you
    through both replacing your old router or hooking it up to use with your old
    router....very clear & helpful.

    Thanks for your input.

    your old router is a 10mb unit and is ok at 6-7mb your new one is a
    100mb which takes the full bandwidth of the cable 15-20mbs

    smile now please

    I hadn't even thought of that. They had functioned without a hitch for over
    6 years....until bandwidth overtook them.
