Make sure the wireless products you are using to connect to the Wireless Router support 54 Mbps speeds. Only 54 Mbps wireless products can connect to the Wireless Router at a rate of 54 Mbps. Launch the router's Web User Interface and manually set the connection speed to 54 Mbps. If you are using non-USRobotics wireless products, you may need to update the firmware for those products in order to support 54 Mbps connections.
Low connection speed or range can also be caused by environmental interference. Try to move the product around to improve the link quality. In addition, keep in mind that other factors such as lead based paint, concrete walls, and electronic items such as 2.4G phones may affect your wireless range.
If you have not enabled security for your router, you may have unauthorized wireless devices using your network and slowing down your access. To set up the security features available for the Wireless Router, you need to log in to the router's Web user interface and configure your wireless security settings.
