The basic idea behind a broadband router is to allow two or more computers to share In internet connection using a technology called NAT (Network Address Translation). With only a single IP address on the Internet, all of the computers in your home can be on the Internet at the same time. Additionally, NAT naturally acts as a rudimentary firewall by masking the true IP address of our computer - thus helping to keep your systems safe from hackers.
Broadband routers can be as easy or as complex as you want them to be. Available for under £40, you can extend your Internet to all the computers in your home. A simple broadband router is both easy to install and low maintenance.
