A WLAN DSL router is the point of the wireless local area network setup which will deliver the connection out across the intended environment. The same principle of connectivity applies whether in the home or the workplace. An incoming connection will fed to the router, which usually sits on a specific station which acts the main network server. From this point all network administration duties can be performed and limited access given to it, so that there is no risk to anyone accidentally throwing a spanner into the works of the network. A downed network can cost an organization a lot of money in lost production time, as many stations are likely to be connected to it. The purpose behind a network is to share a DSL connection (otherwise known as a Digital Subscriber Line) allows for the transmission of data over a regular telephone connection. It is from this point which most internet connections are fed into a building, and the router will control how the packets of information are dealt with, in an order of priority across the network. Many WLAN DSL routers will have network print capabilities, allowing for many users to share access to printers within the office. The router will also provide IP address routing services, along with firewall and network switches, all geared to improve the performance of the network connection. Otherwise known as a residential gateway, thanks to its usage within the home, the WLAN DSL router essentially acts just as that, a gateway to link numerous devices to a central network. This provides efficient and cable free connectivity, an advance from the confines of having cabling running everywhere, and new access points having to be installed if a new workstation needs to be added in a different location. The functionality of being able to connect to the network from any location within range of the main access point, brings a lot of benefits, especially those of portability. The DSL router will manage all of the connections between computers, printers and the main server itself. Updates to the network will be done at the main server, should there be a call for maintenance or network upgrades to be done. Any widespread upgrades can be sent out across the network simultaneously. The WLAN DSL router will be the vital link, the heartbeat of your wireless network. There will always be security issues, but these should be expertly addressed by the network administrator when the network is initially set up, and maintained throughout its operation. A well run wireless network should provide extremely efficient networking capabilities with the added benefit of the freedom of mobility.
