Help Please!! Trying to use Airport Express as a repeater

[mag122774]

I currently have a Airport Extreme in my living room, I'm trying to boost up the signal in the rooms. Is there a way that I can use Airport Express as a repeater in the rooms via wireless and not via ethernet? I would like to use Express as a signal booster not to stream music

If you already have a wireless network in your home and would like to extend its range, AirPort Express is the answer. For example, suppose you want to extend the range of your current AirPort-based network to your backyard, garage, or attic. You can use AirPort Express as a wireless bridge to extend the range of your primary base station.

There’s no need for extra wires or cables. Just place AirPort Express in range of your primary base station (either an AirPort Extreme Base Station or another AirPort Express Base Station) and near the area where you want your wireless connection. With its easy portability, you can even move AirPort Express from place to place. So if you want to connect wirelessly from your basement one day and your garage the next, just plug it in within range of the primary base station and in a spot near those areas.
