Experimenting with increasing wireless distance

Background

Transmitting an existing connection and initialising a new connection (from today’s experiment) seem to be 2 different things. Below is my attempt at increasing the range of a Netgear DGN2000 wireless router using some basic materials.

Equipment

Laptop, wireless router and some anonymous bits and pieces.

The test

To see if combining physical objects with the router can increase the distance of a wireless connection.

Router with assistance

Using a dish shape

I made a couple of fibreglass cones and covered them with aluminium foil. From there I placed a cone over each of the 2 antennas of my router (line of sight down the street).

  • You can see from the graph below, the distance of the wireless in a sustained connection is increased by approximately 50 % using the standard router as the baseline. The ability to initialise a new connection resulted in a 0% improvement using the standard router as the baseline.

Using a panel of corrugated metal

I tried this method because I read a blog post where a guy claimed that this is the best method to increase wireless range. It is basically a piece of metal shaped in a curve and placed behind the wireless router like a dish. The results of this test were interesting.

You can see from the graph below, the distance of the wireless in a sustained connection is increased by approximately 25 % using the standard router as the baseline. The ability to initialise a new connection resulted in a 100% improvement using the standard router as the baseline.
