Yes some wireless routers can be configured to act as wireless bridges. You need to be aware though that typically the way it works is the extender joins the wireless network and additional devices are connected via the LAN ports on the device you're using to extend the network. If your firmware doesn't support bridge mode (D-Link for instance removed that from a lot of their newer router firmwares) you should look into installing dd-wrt
on the router
