The Classic Linksys "WRT54G" Router is a favorite among enthusiasts for it's open architecture and ease of modified firmware uploads.Dave's been experimenting with upgraded routers. A whole subculture of software writers have taken advantage of the Linux open architecture and using the full capabilities of the linksys box..

We've experimented with two firmware upgrades that essentially "supercharge" these routers.

Tomatoe is the current firmware under evaluation

DD-WRT was an earlier firmware evaluated.

Check their websites for all of the goodies including "uppiing" the power output of the radio .

Increased power helps "punch" through the often cloudy northwest weather.

Valhalla is unable to connect to the high speed broadband wired network due to Comcast will not install a tap in their fiber at Jordan Road & 155th.

Here's a current diagram of the Valhalla Wi-Fi network. The center of the system is a classic LinkSys WRT-54G router connected to a Hughes Satellite system.


Foscam IP Camera on the workbench.
These can be had for $80 on the internet. By using the router's "port forwarding" feature, this camera had be "seen" on the internet.
In fact we are using a similar Foscam camera to surveil our Maricopa House

  • When you start mounting and using IP cameras, you need to consider "Video Capture" Software.

     

  •  After checking out the available products.
    We settled on Blue Iris

 

Here's a shot from the Pump House Cam.
The motion controls and other options available using Blue Iris is incredible
 
   
Here's an experiment we ran last summer.

Here's another test using a 16db gain yagi

Here's a sketch of config we tested 
The diagram shows two linksys routers.
One configured as "ACCESS POINT" and one configured as "WIRELESS CLIENT".
 

               



Here's an early sketch of a "mesh" wifi system we  considered.
Each node sends and repeats the hi speed internet

Here's a sketch of a "2-bounce" wifi system using the upgraded routers. Each node sends and repeats the hi speed internet.
These routers are cheap and plentiful and  can be configured for several different jobs, access point, repeater and wireless client are just a few. With an easy to use GUI, these routers can be customized with many features and options considered.
