The Wireless bridge

What is the wireless bridge?

This is used to interconnect two networks, layer 2 of the link layer of the OSI model. So it connects two strands separated networks. This is not a router, do not get confused...

The geographical converture

Currently the bridge is mainly used to make a geographical wifi extended coverage. In this spirit we have a wifi router to emit 30m; to expand our reception area we will install a bridge or access point to extend wireless coverage to approximately 50m.

Distance coverage may vary depending several criteria, significant in the deployment of an installation:
• Scope of issue of antennas,
• broadcasting area, mountain:


*

• • humidity,
  • fog,
  • snow,
  • etc...

Materials

• To establish this converture can be used plurieurs type of equipment including: La Fonera!

• You can also use a simple signal amplifier which acts simultaneously as a gateway:

XP network bridge: between a wired network and a WiFi network

It may be that we want to share an Internet connection to another PC connected on Wifi Ad-Hoc, in addition to other PCs connected by a wired network. In this case it is necessary to create a network bridge between the 2 network interfaces (wired and WiFi) of the PC sharing the same internet connection. However, some WiFi cards can not work this way. Indeed once the bridge created the WiFi is no longer operational.

To fix this small problem, you should:
In a DOS window, type the following command:

netsh bridge show adapter

Locate the card number responding when the bridge is active. If he says that your card is not in compatibility mode then do this:

netsh bridge set adapter x forcecompatmode=enable

Replace x by number of your card displayed at following the previous command.
