How to bridge two wired networks via wireless: WDS AP Bridge:== Key Terms to Know ==Connecting two Networks Wireless is called Wireless Bridging. The term Bridging is a rather precise term in professional Wireless Networking. Unfortunately in order to “lure the mass” the Marketers of Entry Level Wireless Hardware do not adhere to terminology. As a result it is important to understand the simple principles of Bridging rather then to adhere to words that might be misleading.Terminology is everything since this is a dynamic technology where old school definitions crash into slick marketing slang and, in general, an abuse of technology terminology in order to promote and sell products. So here are some key terms to remember:* WDS - Wireless Distribution System* WDS repeater hop - a single hop repeater is another way of saying a bridge with two Access Points* Mesh Access Points - WDS isn't the only way to bridge and repeat, however, WDS is a type of Mesh wireless networking == How to bridge two wired networks via wireless == WDS AP Bridge: Connecting two Networks Wireless is called Wireless Bridging.

As a result it is important to understand the simple principles of Bridging rather then to adhere to words that might be misleading.== Key Points to AP Bridging ==Detailed specifications for WDS have yet to be created and agreed upon in the industry. What this means is that if you wish to create a WDS bridge it is best to use two identical products from the same manufacturer running the same bios.== Throughput / Speed ==Inexpensive 802.11g based mesh APs are available from Open-Mesh. Be warned, however, that throughput via 11g meshes is very low, in the single digit Mbps range. This is fine for basic connectivity for email, web browsing, etc. But not enough for high-quality video streaming. With WDS added to some 802.11n routers, it's now possible to get double-digit bandwidths through a single-hop bridge.== Security ==The focus here is primarily on a single hop WDS bridging two wired networks via a wireless link. WDS AP Bridging is restricted to WEP encryption due to the nature of the two radios as explained above. The security therefore comes in using MAC addresses so the two AP's only connect to each other via radio link.WDS connections are MAC address-based. When discussing the 802.11 standard the WDS connection utilizes a special data frame type that uses all four of the (MAC) address fields. In the 802.11 frame header, address 1 is the destination address, address 2 is the source address, address 3 is the BSSID of the network and address 4 is used for WDS, to indicate the transmitter address.
