How to Set Up a Linksys WRT54G Wireless G Router

By Aaron Parson

Learn how to set up your WRT54G, WRT54GS or WRT54GC router for both wired and secure wireless connections.

Setting up a Linksys WRT54G series router requires two steps. First, plug in all the cables to get your wired Ethernet connections up and running. Next, use the router's Web interface to set up Wi-Fi, enabling wireless Internet for your laptops and mobile devices.

Hardware Setup

Step 1

Plug the Ethernet cable from your cable or DSL modem into the Internet port on the router.

Tip

If you've been using the Internet without a router — running a cable directly from the modem to your computer — disconnect the Ethernet cable from the back of your computer and plug it into the router's Internet port.

Step 2

Connect one or more computers to the Ethernet ports on the router, labeled 1 through 4. The order doesn't matter; all four ports work identically.

Step 3

Plug in the router's power adapter and wait a few minutes while the system starts. You now have Internet connectivity on your wired computers.

Wi-Fi Setup

Step 1

Visit the Web address 192.168.1.1 in any Web browser on a computer connected to the router. Log in with the password admin, leaving the user name blank. If that doesn't work, enter admin in both the user name and password fields.

Tip

If neither of these default logins work, reset the router by holding the Reset button for 10 seconds until the device reboots. After a reset, try both options again.

Step 2

Open the Wireless tab in the router's setup interface.

Step 3

Basic Wireless Settings page.

Pick a name — SSID — for your wireless network. Everyone in range of your router can see the name, so don't include any private information. Leave the rest of the options on their defaults. Click Save Settings and then Continue.

Tip

Return to this page and change the wireless channel if you are disconnected from Wi-Fi frequently or have low speeds. Only use channels 1, 6 or 11 to minimize interference from other networks.

Step 4

Wireless Security page.

Open the Wireless Security tab. Set the security mode to WPA2 Personal and enter a password of at least eight characters in the Passphrase or WPA Shared Key field. Click Save Settings, and your wireless network is ready for use.

Tip

  • The wireless password is not the same as the router's setup password, which is "admin." To change the setup password, open the Administration tab.
  • Some old devices do not support WPA2 Personal security. For example, the PlayStation Portable uses the older WPA Personal option. Original Nintendo DS games — played on any system — only work with WEP, the weakest security protocol. If you change to one of these options to use an old device, change back to WPA2 Personal afterward to keep your network safe.
