LinkSys is a brand of computer networking products. Producing routers both wired and wireless. LinkSys is by far the most ubiquitous router in use for home users and offices. It's not always easy to set up a wireless router with a Windows client. Linksys routers come with a step-by-step Setup Wizard which makes setup and configuration easy to understand.
Set up a Linksys Wireless Router
Attach the antennas to the Linksys wireless router.
Place the router in a central location, making sure it's not surrounded by metal. (A signal can't be obtained through metal.) The router should be located so that the distance between clients (computers) is somewhat equal. This will create a better connection.
Plug the Ethernet cable into the "Internet" port on the back of the Linksys router.
Connect a computer to the router
by plugging another Ethernet cable into the Ethernet port on your computer and
attaching the other end to one of the available ports on the back of the
router. You can choose any port except the one labeled "WAN."
Plug the router into an electrical outlet.
Wait for the power light to stop flashing, at which time the router is finished booting up. While the router is booting, the power light will be blinking. This process may take a few minutes to complete.
Reboot your computer so it can access a new IP address from the router through the Dynamic Host Configuration Protocol (DHCP)
