WRT54G Antenna Upgrade question / Wireless Network Setup

Discussion in 'Networking Issues' started by AlmightyMe, Dec 21, 2004.

    Hello,

    I am wanting to connect 2 seperate antenna's to my WRT54G v2. One would be an internal "Smoke Detector" antenna in the middle of my home and one would be run to the roof as an external omni or directional (not sure yet). My question is, does the WRT54G use both antennas to both transmit and recieve thus allowing for what I want to do?

    With that done I want to connect my parents home and my home using a wireless bridge. Finding the WET54G will not pull a wireless signal even 6 inches from my WRT54G I decided to go with Open Source Firmware.

    The houses are approx 500ft line of sight with your typical trees and houses in the mix.

    Would I be foolish to think I could run a larger 15 dBi Professional Omni WLAN Antenna to create a wireless network that could be repeated by a single WRT54G?

    Or should I be thinking 24 dBi Heavy Duty Grid WLAN Directional Antenna to the same antenna on the other end. At that point I would need to connect the bridged WRT54G to an Access Point to rebroadcast the signal through his house. And hopefully could use the built in switch to connect to CAT5 connected LAN devices.

    What would you guys (and gals) do?

    AlmightyMe:

    Use OpenSource firmware. Absolutely.

    Configuration:

    Your house: High gain parabolic grid or YAGI pointed at mom and dad's. Turn off one ant on your router. Get a access point and wire it to your router for your own internal connection.

    Mom and Dad's: AP/bridge with high gain parabolic grid or YAGI pointed at your setup. Patch ant in their house. -OR- get second bridge unit and hard wire it to the receiving AP.


    Here's a diagram:

    Client Bridge---Router---YAGI<-------->YAGI---Client bridge

    Patch ant (5dBi)
    (Mom and Dad)

    Tip: If using grids, try mounting them in horizontal polarization.

    CORRECTION - DIAGRAM FORMAT LOST

    The diagram got a little messed up when it posted. The DSL/Cable goes to the router. I am sure you know that. Just wanted to clarify.

    heh why would you need for such a short distance a high gain antenna? I have a bridge connection with 2 WRT54G and 2 biquads. The biquad has about 12dB, and this means if you set your routers xmit power to 56 and combine this with a biquad, you can get a connection for 2-4kilometers!!!
    Are you planning to buy a antenna or to make it yourself?

    Antenna power

    It's just my philosphy to have more is better. If you had to dig a hole 10 feet wide and 10 feet deep, a shovel would work. Right? But wouldn't it be better to have a bucket loader?
