Routers essentially perform the same function but are not created equal. Routers have two major categories, with and without wireless capabilities. Routers are rated as to how fast they transmit data and how compatible they are with a particular piece of peripheral equipment. Wireless routers in particular are rated as to what speed they can transmit data and also how far that data can be transmitted and its ability to transmit through certain barriers like walls and floors. Our team at GBT are happy to help with any router questions and sales.
