Add a Wireless-G range expander. Simply place the device in a location within range of the wireless router, plug it in and push the button. The expander automatically configures itself to the wireless network and relays the signal to wireless devices, even those that are hard to reach.
Use a wireless USB adapter with external antenna when signal becomes poor. These are great for use with laptops, since signal strength varies from location to location. They also come in handy when connecting to wireless high-speed Internet in hotels.
Upgrade the existing router to a new Wireless-N router. Obtaining the newest technology ensures that you will receive the best signal possible so that you can make the most of your wireless Internet.
