I get asked a lot about how it works and what we use so here is a brief explanation.

We have a 2.4ghz standard wifi A/G network setup in a star configuration. The central house has a Linksys WRT54G wireless router attached to a standard ADSL 2+ modem, a very reliable unit which has external antenna connections unlike some other wireless routers, you can get these pretty cheap on Trademe. Attached to that and mounted on a small mast is an omni directional antenna from www.gowifi.co.nz something like this.

Each client house has a Linksys WAP54G wireless access point, these are again solid units and we used them because they can be used in reverse as a client instead of an access point. Note – there is a strange bug when configuring these, you need to use IE or Chrome when accessing the configuration panel as some editions of Firefox do not work with it. These have a directional antenna (similar to this) aimed at the hub. Most of these are inside houses and aimed through a window.

Almost all our failures have been at the modem, either it losing its session and not restoring it properly with the provider or it dying completely. We also have a troublesome shelter belt that has grown up and blocked two houses – the gear is true line of sight stuff.

This has enabled our house to lower its telecoms bill from $100+ to $20 by using a voip provider for the phone. Voip is getting better and better in this application but was inconsistant for the first year – still, we are early adopters and that is what you get.
