Do you have a large home in which your wireless router signal is not available in some locations. I have that situation in my home, where the kids bedrooms wireless signal is 1 bar or less. Today I fixed that by installing a Linksys RE1000 Wireless-N Range Extender.
Total setup time of the wireless range extender from opening the box to having it installed was 10 minutes. The kids bedrooms now have 5 bars of wireless connectivity. I am not sure why I did not do this earlier, as it is going to cut the kids complaining considerably. While we have strict family policies on what can be done on the Internet in their own rooms, when it comes to doing homework I would rather have them focused in their rooms so my wife and I can be productive and make noise in the rest of the house.
Setup is simple, you use a computer currently connected to the network via your wireless network, you install the CD and it steps you through the process. Of all network upgrades I have made this was simply the easiest by far the only thing I needed to remember was the password for the wireless network.
The Linksys RE1000 also comes with a built in Ethernet port, which you could use to plug a set top box or other device into is that may not be wireless compatible to bridge to your wireless router.. Heck it could even be connected to a printer in another room, or a computer that may not have a wireless card in it.
Priced at 89.00 this is a great way to get more range and add flexibility to your current network configuration. It will plug into a wall plug or you can use the cable it comes with to hide it away.
