text: A very clever approach to extending wireless coverage in the absence of any standard for the extension (I think WDS may be a standard, but it is not well supported):
  Wireless Range Extender For TravelersTwo devices so the proprietary link is hidden.
  I travel frequently, and often need to extend a wireless signal by 50 - 75 feet. Commonly, I can pick up a signal by a window from the next building, but lose the signal deeper inside the structure, where I wish to work. Wireless Range Extenders are the black sheep of wireless. The various WI-FI standards do not specify how a wireless signal should be captured and repeated, so each manufacturer rolls their own, resulting in incompatibility between brands.
  Yesterday, I found a deal on D-Link's TINY and versatile DWL-G730AP Wireless Pocket Router/AP™. As of August 10, 2005 Office Depot in Chicago was selling them at $30 EACH after rebates.
  This little device is smaller than a PCMCIA card - about the size of two graham crackers, stacked - and SMART! An external switch changes the mode between client, access point OR router. It draws power from A/C OR USB, and is fully configurable using D-Link's standard web interface. To boot, it supports WPA PSK.
  I bought two, switched one into client mode and the other in router mode, taught the client which SSID and channel I wanted to bag,plugged them together, and for $60 USD, had a universal range extender.
  To change the default settings, Mac users DO need to know how to create a manual IP on either Ethernet (to customize client or AP mode) or Airport (to tinker with the router). In the Network System Preference, create a location for configuring my various d-link contraptions. Set the IP to 192.168.0.100, subnet mask 255.255.255.0 and gateway 192.168.0.30. Use a browser to connect to 192.168.0.30. The username is Admin, and the default password is blank.
