A router is a device that is connected to the computer in order to note that everything is connected properly and communicating properly. A wireless router, also called Wi-Fi, transforms a webpage or a website into signals, for example radio a signal, which is transferred as radio waves and is collected by the computer. There are various features to be noted when looking for a wireless router.
The wireless speed is an important feature in a Wi-Fi. This is evaluated by the data amount that is transmitted through the network. This is measured in Mbps. Older wireless routers have about 11Mbps of speed. The Wireless G standard has a speed of about 54Mbps and the Wireless N Standard has a speed of about 248Mbps.

The next thing to be considered is the wireless standard. In general, the wireless devices follow a standard of 802.11. This ensures that all wireless routers of different makes and companies work together. With the increase in technology limits, the speed of data transfer per second also increases. There are basically three types of wireless standards that are set up at present - Wireless B, Wireless G and Wireless N.
The older wireless versions use Wireless B standards, that is, 802.11b, which has a data rate of 11Mbps. The second type is the Wireless G standard, which came into existence in 2003 and is explained as 802.11g. This is the most dominant type of standard at present. The third type is the Wireless N Standard, which is explained as 802.11n, transfers music and video data at a much greater speed of about 248Mbps. They are the latest versions and look to be quite promising and efficient. However, this would be approved only after 2009.
Using a USB adapter is a good idea to upgrade a computer or laptop that does has a lower wireless standard. This can be inserted into a spare USB port, or even a PCMCIA card can be used in the case of a laptop. Some routers come with the facility of an antenna to be attached. This gives better range to the routers and thus gives freedom to work even outside or on the other side of the given area. A Firmware is very useful software or a program that is stored in a router permanently. Nowadays latest router models allow the software to be downloaded and also get updated from the manufacturers' site.
A wireless router is a very useful device that sets the user free, to use the computer to transfer data without the help of any leads. With technology improving every moment, we can expect more wonders out of the Wireless routers!
