Hello,

You can connect your expander to your PC via ethernet cable and then assign a static IP address on your PC.

To assign a static IP address, just double-click on the monitor icon on the lower right hand corner of your PC and then view status and go to properties. Look for TCP/IP v4 and click properties.

Select use the following IP address:

192.168.1.2
255.255.255.0

and then click OK.

After successfully assigning an IP address to your PC, let's test the connectivity by going to command prompt.

Go to Start>Run>and then type cmd and hit Enter.
Once you're on the black screen type ping 192.168.1.240.
If you get replies then your good to go...

Let's now access the Web UI of the you Wireless expander.
Open a browser and then type on the address bar 192.168.1.240 and then hit enter.

It will prompt you with WRE54G's username and password. Just type the password to login to the Web UI. The default password is admin.

Once your on the Setup page, you have to configure your settings exactly the same as your wireless router (e.g. wireless security, IP address range) except for the SSID. You may want to change the SSID on your WRE54G for you to easily identify where your wireless computer is connected.

You can leave the WRE54G's IP address to 192.168.1.240 if your wireless router's IP address is on the same range like 192.168.1.x

Then on the Gateway address type your router's IP address. If you're also using Linksys the default IP address usually is 192.168.1.1

Then you can configure your wireless settings same as your router. After that, same the settings and see if the light on the WRE54G becomes BLUE. If yes, then you're good to go! You can unplug the PC from the WRE54G and then set your PC's IP address back to Obtain an IP Address Automatically. See static IP address procedure above.
