Poor signal on other side of the house

    I have a Buffalo WHR-HP-G54 Router that I just bought. It's connectd to
    my cable modem on one side of my house. My wife uses her laptop on the
    other side of the house.

    Her signal fluctuates between almost no bars to 2 full bars.

    I read through the stuff on the EZLAN.NET site but I am still not
    certain which is the best way to get a better signal.

    The router came with a 4dBi Omni Antenna. Buffalo sells an 8dBi Antenna
    but I'm reading that while devices farther away may get a better
    connection, devices that are closer may lose signal strength because of
    the way WiFi antennas work.

    I don't have any way of running Cat5 cable anwhere else in the house
    (it's a rental), so setting up a wired AP in the next room isn't an

    I'd have to set up a wireless AP, which I understand would halve my
    wireless bandwidth.

    Should I just try the $15 antenna first and if that doesn't work, go the
    wireless AP route?

    Would love some advice.

    No. It would halve the throughput only to anyone connecting to the
    repeater. Anyone connecting to the main router wouldn't be halved.

    Unless you have a very fast Internet connection you probably wouldn't
    notice the difference with the laptop's lan connection to the router
    being halved.

    I have a 20mbit connection to the Internet, so I don't know how that
    compares as "fast".

    Would I set up the repeater on a different channel? So that it connects
    to the main AP on one channel but uses another to connect with devices?

    I have a 4 dBi omni on the AP now. Should I try an 8 dBi antenna first
    to see if that helps before spending extra $$ on a repeater?

    Well let's say, operationally speaking, you're very lucky and it's
    half as fast as your 54mbit wireless lan. Halve, the wireless
    throughtput and it's still on a par with your advertised Internet

    If you're both on at the same time you share the wireless bandwidth
    and the Internet bandwidth so it's going to go slower whether you use
    a repeater or not.
    Match the channel on the main router. This is a good tutorial.

    If you have an old router, perhaps it can be re-configured as a
    repeater using dd-wrt or similar firmware?

    I found an old WiFi AP in the garage and pulled the antenna of it to see
    if it would work on my new AP. Funny thing is.. When I pulled the
    antenna off my new one, I suddenly got a better signal on the other side
    of the house. I put the antenna back on and it dropped again.

    The antenna from the old AP didn't fit, but for now leaving the antenna
    off seems to be working great.... go figure.
