I bought a Range Expander (WRE54g) to go with my linksys router (WRT54g). I had to download new firmware for the router to get the range expander to work right, but eventually it worked. Shortly thereafter, the router died. I purchased a Motorola router instead (WR850g), which I plugged in and everything worked beautifully for about 4 months. Recently, the Range Expander begain having problems. After an extensive and thorough conversation with Linksys techs it was confirmed that the range expander was defective and they sent me a new one via the warranty. The problem I'm having is that when I plug in the new one, the link light is red - not blue. Any suggestions on how to make this work?
