Since wireless routers basically waste a lot of their energy blanketing a designated area with a WiFI signal, it's no wonder that some home networks are less than efficient. Some companies are to change this in order to make smarter wireless repeaters to extend and improve your home network.
We've talked before about how wireless repeaters allow you to extend the range of your home network. You can also hack an old router into one. Now, D-Link is introducing a new type of wireless repeater that doesn't just boost signals, but it will target them directly at your wireless antennas for maximum distance and reliability.
All you need to do is to plug the repeater somewhere within the range of your router. The DAP-1525 will detect the signal, and repeat it. However, unlike other repeaters, this one is smart and it targets the beams directly to where your devices are. It will be released in the spring and cost $140.
Belkin's G Universal Range Extender can transform your existing home network into a wireless one. Simply connect it to a wired router and you've got a functioning WiFi network, allowing laptops to access the Internet without creating much of a fuss. A situation where this would be very useful is when you are renovating a room. If the rest of your house is already wired and you don't want to run anymore wires through the walls, simply using a device like this gets the job done.
