It depends on which Linksys router you have as to whether it can be used as a wireless bridge, which allows your router to work in \"Client Mode\". If its one of the WRT versions the you may be in luck.
There are a couple of addon firmware updates that can be used to accomplish that feature. In fact there are several
DD-WRT is one of the most used ones.
http://dd-wrt.com/dd-wrtv3/index.php The software has many functions that simply weren\'t included in the original firmware and running in \"client\" mode is one of them.
Open WRT is another not as widely used but still allows a client mode of operation.

http://www.sveasoft.com/ is another
and last but not least
Tomato:

Loading any of these to your linksys \"WRT\" router will allow it to work in the client mode you need to use it as a bridge and connect wirelessly to your other router. Do check the \"hardware\" lists on the firmware to be sure your MODEL router is supported. Loading the wrong one may \"brick\" the router!
Here is a good \"how to\"

(They really aren\'t too bad to run and aren\'t all that expensive from most sources. Local stores usually charge much more than they should for cables.)

Hope that helps

Check the web based setup interface on your router. Many units (like several Zyxcel routers) will include a mode setting which says \"Client Bridge\". If your router has that setting, all you need is select the setting and setup the \"bridge\". That is simply a matter of entering the SSID (network ID of the prime router) and secruity settings into the second router and click the \"connect\" tab. Your setup is complete.
There are routers and gateways which support \"WDS\" which is short for \"Wireless Distribution System\". If both routers have the WDS function you can simply turn on WDS support. This causes both routers to \"work\" together as a \"single\" access point and allows the \"second\" router to pass data from the wireless radio to the ethernet just as if it was connected with a cable.
Check your routers \"web based\" interface to see if WDS is supported on both units. If so, give it a try that may be all you need to do.
