The mobility and the convenience of wireless Internet connection makes this technology preferable to anything we’ve used before. DSL stands for digital subscriber line and it defines the kind of Internet connection service available to a user. In case you have a pre-configured DSL modem, you have to buy a DSL wireless router too, meaning that the connection has to be the same. A DSL Internet connection cannot match a router designed for cable connection. There are wireless routers designed for both cable and DSL connection. It’s all about checking the compatibility.
A DSL wireless router includes four LAN ports on the average for the connection of laptops, desktops and other peripherals. A switch will be required for the connection of more wired devices. In order for the computers to be connected without cables to the DSL wireless router they have to include wireless LAN cards, either external or built-in. The DSL wireless router sends radio signals to the PC LAN card with its antenna and the computer converts the waves into data that can be then decoded.
Before you purchase a router, you need to find out the wireless standard that corresponds to the data transfer speed of the network. The normal data transfer rate standards are 802.11a and 802.11g, which you may already know by the name of Wi-Fi, and they provide 54 Mbps. The newest standard is 802.11n, and it has an incredibly high transfer rate of 540 Mbps. When the DSL wireless router and the computer’s wireless network card follow the same networking standard, you will have a good wireless LAN and WAN connection.
Another compatibility issue appears when considering data security in wireless networks. The security of your data should be the primary concern when purchasing routers. Thus, the device should follow the Wired Equivalent Privacy features which allow for Wi-Fi Protected Access or WPA. It is following a certain protocol that the radio signals are encrypted and the network is kept safe.
The DSL wireless router comes with an external or an internal antenna, depending on the model. Modifications are possible if the antenna is detachable or if you have the possibility to attach another one. Don’t make a purchase without checking all the functions of the router; find out if the device can also work as a switch or hub and see if it includes supplementary firewalls.
