    I need to use a router in order to save 50 bucks a month for an extra
    DSL line. The problem is that the router will be in one building while
    the computer will be in another that's about 300 feet away. There is a
    pretty open area between the buildings and I'm out in the woods. Can
    this be done fairly easily?
    Thanks,
    Eric r Snow

    For some values of "fairly easily", you can rig up a USB wifi adapter.

  3. You could use directional antennas at both ends. Search on "wifi
    cantenna" for a waveguide antenna that's easy to make out of a quart-sized
    can. The only parts you will have to buy are the coaxial connectors and
    the cables to connect to your router and computer; the rest is scrap. You
    could also run cat-5e cable, but that would cost more.
     
  4. I would recommend the cable if it is possible.

    Otherwise, 300 feet is not difficult with wireless. But
    there are a few things to keep in mind. One is that
    coax is a very very lossy transmission line for wireless
    frequencies, and therefore it should be kept as short as
    possible. And for anything longer than a foot or two,
    use *expensive* cable.

    What that means simply is the location of the hardware
    should be chosen to keep transmission line lengths
    short.

    I need to use a router in order to save 50 bucks a month for an extra
    That should not be a problem. You just need the correct antennas. In Sout
    Africa I would use poynting antennas www.poynting.co.za, they clai
    distances of 40 km and more (with legal power output and earth curvatur
    becoming the limiting factors). I would suggest looking at somethin
    similar in your area, or a local distributor.
    For 300ft I would think that the more basic omni directional antenna
    would be more than adequate, especially because there is an open are
    between the buildings.

    More wifi info discussed in the below group. The buffalo products
    (bottom) seem to be good for longer range wifi connections.

    I purchased this yagi antenna from MFJ.
    http://www.mfjenterprises.com/products.php?prodid=MFJ-1800
    It is the highest gain antenna I've got and I've built different5 so far.
    At $29.95 it's cheap, however the shipping is was about $12.
    Also you may need to buy a USB adapter with an RF output
    connector. As someone else said, RF cable is lossy at this frequency,
    so us as little as possible.
    I eliminated RF cable completely by attaching a connector directly to
    a USB dongle and then connecting this to the antenna. Then from the
    dongle I run USB cable to the computer. 15ft of USB cable is about the
    limit unless you add line amplifiers.

    There's a news group for wireless stuff, you may want to ask there.
    But in the mean time, there are a few wireless routers that can pump out
    quite a bit of power. WHR-HP-G54 is one.
    That combined with DD-wrt firmware, makes it a kick-ass combination.

    Do a google search on dd-wrt. They build after market firmware that can
    be loaded on many of the wireless routers available. It gives a plain
    jane router the capabilities of the high dollar routers.
    And the best thing is that it is free!
