How to Set Up a Linksys Wireless Router for WiFi

By Jonah Quant

Wireless computer networks work by having a wireless access point act as nexus between a wired network and all wireless clients. Many access points in the market also incorporate routing capabilities. The wireless router needs to be configured with parameters that will determine characteristics of the wireless network, access restrictions for clients, security options and nature of the connection to wired, external networks. You can configure a Linksys wireless router for the specific characteristics needed on your wireless network.

Things You'll Need

  • Two Ethernet cables

Step 1

Turn on the wireless router. Connect the "WAN" port on the back of the router to the connection provided by your Internet Service Provider (ISP), using an Ethernet cable.

Step 2

Connect the computer to any of the numbered ports (typically labeled "1" through "4") on the back of the router, using the other Ethernet cable.

Step 3

Launch a web browser on the computer, then navigate to the web address for the router's configuration utility. This web address depends on the router and can be found on its documentation. For example, for a WRT54GS, the default web address is "192.168.1.1". The configuration utility will come up on the web browser.

Step 4

Configure the basic characteristics of the wireless network. For example, for a WRT54GS, click "Wireless," then "Basic wireless settings." Enter a name of your choice for the wireless network, then choose a channel. Channels 6 and 11 are the best, unless there happens to be radio interference at your specific location. Click "Save settings."

Step 5

Configure the security (encryption and access control) characteristics of the wireless network. For example, on a WRT54GS, click "Wireless," then "Wireless security." Select "WPA Pre-shared Key" on the "Security mode" pull-down menu. Enter a passphrase of at least 16 characters (including numbers and punctuation) in the "WPA shared key" field. Wireless clients will need to know this passphrase in order to join the network. Click "Save settings." At that point, the wireless network will be ready to use.
