Expand the range of your wireless network! The Linksys Wireless-G Range Expander is the easy way to increase the effective coverage of your wireless network. Unlike adding a traditional access point to your network to expand wireless coverage, the Wireless-G Range Expander does not need to be connected to the network by a data cable. Just put it within range of your main access point or wireless router, and it bounces the signals out to remote wireless devices.
