I recently had the opportunity to test out the Buffalo Wireless-N Dual Band Ethernet Converter and I was impressed with its relative ease of use. Basically what the device does is it picks up your wireless signal and converts it to a physical connections. It allows you to physically connect devices to the network where there are no Ethernet connections. It is a relatively small device with 4 Ethernet ports on the back. It comes with an installation CD and a network cable.
I found this device rather easy to setup. All I had to do was plug it in, connect the cable, and install the software on my PC. The software is very light weight and quite simple. It allows you to pick which connection you want to use and in my case I used the physical connection. I set the device just for testing purposes to acquire an IP address automatically. The device will automatically scan for wireless networks. You just need to choose your network provide the device with your security settings (SSID, security type, passcode).
After doing all of the above, I saved the settings and restarted the device and my internet was running through the device and allowing my laptop to have internet access. This is perfect for devices that are not close to Ethernet ports including gaming consoles, printers, media players, IP Phones, and more. I would definitely use this at my own house, therefore I would recommend it to others. Check it out for yourself.
