Here are important FAQs you need to know about Linksys Range Expander.

Q: What is WRE54G v3?
A: It is a Wireless-G Range Expander which increases the effective coverage of your wireless network.

Q: What is the greatest signal range I can expect to receive, when using the WRE54G v3?
A: It varies on the environment in which the expander is located. It is best to centralize the expander between the wireless router or access point and the wireless computer.

Q: What is the default IP Address, Username and Password to login to the WRE54G v3?
A: The default IP address 192.168.1.240, Username blank or empty, and Password ”admin” are used to log in to WRE54G v3.

Q: What LEDs does WRE54G v3 have?
A: The LINK LED lights up when the Range Expander is powered on. This LED will light up blue when the Range Expander has connected to an access point or wireless router. It will light up red when the Range Expander is not connected to any access point or wireless router.

The ACT LED lights up when the Range Expander is powered on. It will blink when there is wireless network activity.

Q: What buttons are found on the WRE54G v3?
A: You will find the Reset button and Auto-Configuration button on the expander’s side panel.

Q: What is the Auto-Configuration button?
A: The Auto-Configuration button is used to easily connect the range expander to the nearest wireless network through an access point or wireless router.

Q: Will the Auto-Configuration button work, if the existing wireless network is secured?
A: No. Your wireless network’s security must be disabled for the Auto-Configuration feature to function. To configure the WRE54G v3 to connect to a WEP-protected network, use the setup CD or web-based setup page.

Q: What operating systems can be used to run the Setup CD?
A: The setup CD only works on Windows 2000 and Windows XP operating systems.

Q: What levels and types of wireless security does WRE54G v3 support?
A: It supports 64/128 bit WEP and WPA Pre-Shared Key (TKIP).

Q: How does the WRE54G v3 synchronize with the wireless router or access point?
A: It synchronizes with the wireless network’s SSID since it’s a universal repeater.

Q: What is Wireless Distribution System (WDS)?
A: Wireless Distribution System is a system that enables the interconnection of access points wirelessly.

Q: If the SSID broadcast is disabled and the AP or a router does not broadcast the SSID, will the WRE54G v3 still connect to the AP or a router?
A: Yes. However, you have to specify the SSID in the setup wizard for the WRE54G v3.

Q: Does the WRE54G v3 broadcast its own SSID?
A: Yes, and it can also be disabled.

Q: Will the WRE54G v3 work with a Linksys Wireless-B (BEFW11S4) router?
A: Yes. Using firmware version 2.01.10 and above, WRE54G v3 will only work with BEFW11S4 v4 with firmware version 1.50.14. However, it is not
recommended since the range expander will decrease the transmission speed by half.

Q: How many WRE54G v3 can I use at a time?
A: You can use multiple WRE54G’s per wireless router or access point. Remember that the transmission speed coming from each Expander will be half
that of the source (this also applies to connecting a WRE54G to another WRE54G, and so on).

Q: Can I cascade multiple WRE54G’s? (i.e., |WRT54G| –> (WRE54G) –> (WRE54G) –> (WRE54G))?
A: The WRE54G is capable of being cascaded. However, it is not recommended that you cascade more than one WRE54G unit. This is because cascading more than one unit will decrease the throughput to less than 1Mbps.

An example of cascading is as follows:

| Router | ——-> (WRE54G) ——-> (WRE54G)

Q: Can you back up and restore settings on WRE54G v3?
A: Yes. You will find the option for Back up/Restore Setting under the Setup - Password tab of the expander’s web-based setup page.

Q: What should I do if the Setup CD cannot find the expander?
A: Press the expander’s Reset button using a pin or a pen for 5 seconds to reset the expander’s settings back to default then disconnect the Range
Expander’s power. After 30 seconds, connect the power again.
