These days it is pretty common that a new laptop will contain some sort of wireless adapter. Yet that doesn’t mean that it supports the latest technology. What about connecting your desktop computer via wireless? In any of those situations, it is a good idea to have a wireless adapter that connects via USB.
Both of the situations ring true for me. My laptop doesn’t support 802.11n and it doesn’t work very well if it is more than 50 feet from a router. I also have a desktop computer that isn’t near an Ethernet port. That led me to a search for USB wireless adapters and I think I found a great mix of a powerful component at a very reasonable price in the Linksys WUSB300N-RM Wireless N USB Adapter. The “RM” in the name stands for refurbished which helps to keep the price down to only $24.99. At that price, I didn’t hesitate to get one for both my laptop and desktop. It also could be handy if you have a guest in your office (or your home) who needs to connect to your wireless network. One of my friends always keeps a USB wireless adapter handy for guests in his home.
