U.S. Robotics Extender or repeater will work with USR5461, USR5465, USR9108. This repeater can work with other routers but , you must do the research as I am not responsible for incompatibility issues. The USR5441 is in like new condition and comes with antenna, etthernet cable, power supply, and CD with manual / installation software. I also list on a site called Bonanza, Bonanza allows anyone to view all the items I have listed in one place. If interested check out my other (click to respond)/booths/snellspeakers
