How To: Manually Setting Up the Linksys WRE54G Wireless-G Range Expander – Update


Linksys' WRE54G Wireless-G Range Expander [reviewed here] is a WDS-based 802.11b / g repeater. Its purpose is to receive a signal from an Linksys WAP54G access point or WRT54G and WRT54GS wireless router and relay it to extend a wireless LAN's range.

The Linksys WRE54G

The Linksys manuals make the setup sound easy. It is, if you have nosecurity turned on, do not plan to use security and there is only oneAP near by. If any of these criteria is not true, you will probablyneed to do a manual set up since the Auto-Configure button on the WRE54G will just not work withsecurity enabled. Trying to use Auto-Configure with multiple APs in-range is also dicey and can waste loads oftime.


- The WRE54G's firmware has changed significantly from 2004, when our first How-To was published. This version reflects the Version 3.01.01 firmware that is current as of this writing. If your WRE54G’s firmware is pre-version 3, then refer to our original instructions.

- References to "AP" can be interpreted to mean access point or wireless router.

Most network gear can be initially installed where it will be used. But for a manual install, this is not true of the WRE54G. We recommend that you startsetup with the WRE54G located next to the target AP and use a computer connected via Ethernet.

You will need to gather the following information before you can begin setting up the WRE54G:

  • The AP's IP address and gateway address (logon to the AP's control panel, usually at The first three numbers also give you the IP range of your LAN. So if your AP's address is, your IP Range is 192.168.1.XXX, where XXX is a number from 1 to 254.
  • If you have more than one AP, then you need the IP and MAC address ofthe AP that you want the WRE54G to connect to (a MAC address looks like 00:14:BF:7B:E7:84). If you only have one AP,don’t worry about the MAC address, but you will need to know the IP.
  • Your WLAN SSID (wireless network name). You will findit in the AP's control panel or in the wireless properties of a WLAN client.
  • The type of security the AP uses: WEP or WPA-PSK and the key used. This is also located somewhere in your AP's admin interface.
  • Make sure that the WRE54G's default address( is not in use. If you have a small LAN with only a few clients, you're probably ok. If you are using DHCP to assign client IP address information (most small LANs do), just check the list of DHCP clients that you can usually find in your AP's admin interface.
