    i want to extend the wireless signal coverage ..
    There are rooms and walls between the wireless router and the adapter.(~ 35M) i can get only 70% signal :(

    Should i buy another antenna ?

    WRT54G V5
    WMP54G V4

    you could also try a 3rd party firmware so you can bump up the power of the antenna

    For the 1 millionth-time:

    Build a reflector. Or purchase an improved antenna if you don't feel like making a simple corner reflector or don't like how unprofessional they can look.

    @jgutz20: It is not useful to run around bumping up transmit power in average home setups. It *looks* like you have made a huge improvement because you see more bars of signal in your client laptop utility. It does not represent REAL improvement however because your weak laptop signal is still the same. This is 2-Way, it needs to be symmetric to be useful. All that is achieved in most home setups is many times more noise and interference being tossed out into the street.

    A good reflector is like a cone. You can hold it to your ear to hear whispers far away. Or you can hold it to your mouth to directionalize your voice so it reaches farther. It improves both receive and transmit equally and is in every way the best solution.

    Unfortunately , my router WRT54G do not support 3rd party firmware :(

    So sorry, bad luck there.

    Still, better antenna will improve range. Directional or reflector if nearer to edge of house or clients mainly on one side of unit. If in direct center of house and clients spaced all around, that's the case where a pair of higher-gain omnis will help.

    then the reflector should place between the router and the adapter?

    I think you are not getting it. Go look at the pictures on the web site linked at the very first reply.


    It's just like the reflector on a flashlight bulb. You put it "behind" the bulb to focus the light in the other direction. See?

    Many thanks :clap:

    I placed the router to another position.
    I tested the speed of the internet connection, it's around 480-500 kbp/s. ( :( , i got around 1.5 megabits per second in the wired connection) The signal strength reported by windows is "good" , sometimes
    "excellent". :eek: Why ?

    Will a better antenna gives significant improvement to the speed ?
