Requirement to have a Shared internet Connection between an two buildings that are within close proximity

This Job involved setting up a Wireless Network BRIDGE between the Outhouse network and the Main House.
Setting up a Wireless bridge is the obvious option because of it's comparative simplicity and cost saving (compared with having to run a cable across a path and round a building), and has many other advantages, such as lower maintenance costs, quicker to setup etc.

Howerver, some of the disadvantages are, it can me more complex to setup, and it is important to note that Security considerations MUST BE taken into account when doing this, as Wirless signals can be picked up from outside the building. Hence if you are thinking of doing this it might just be wise to employ the services of an expert (such as XL Computers)

The idea of the Wireless bridge is to make a connection between two LAN segments, so that the two networks appear as one, and can therefore share resources such as One Internet connection, Shared Printer/scanners etc.
Wireless bridges are based on the 802.11(x) protocol and can be set up almost anywhere to transmit data to an router / access point that is wired to the main network. The second bridging router can then be connected either wirelessly or using the hardware ethernet connections to Computers in the other building, thus producing a bridged network. The key to this is to make sure both network segments are in the same subnet for their connection with a wireless bridge. If they have to be in different subnets then NAT is requried which can add to the complexity for a simple network.

When setting up such a network, there are three main things to consider:

1. Make sure the secondary bridge router is set to "CLIENT MODE".
1. Make sure the secondary bridge router is set to a DIFFERENT IP address to the primary, but in the same subnet (e.g. Most routers are set to a default IP, such as:, in which case change the second one to:
1. Make sure the secondary bridge router has "DHCP" disabled. This is because the primary router then manages the automatic addressing for the rest (secondary part) of your network, and there will be no address conflicts!. There are many good websites that have detailed instructions on how to setup a specific network bridge, but if you still need help in this regard, feel free to call us on 091 770078 or visit our website ()
