The Buffalo Ethernet Converter was a life saver for me. At the time of purchase I lived in a flat. A very large 5 double bedroom flat with 3 bathrooms, it was the best flat in the world!.... I digress.... 4 of us lived in this flat and annoyingly when our cable internet was installed, the only point in the place they could put it was right at one side of the flat. So everything that wasn't in this room would need to be connected to the internet wirelessly. As there were 4 of us living in this flat there was quite alot of things that needed connecting, I myself had to connect a PC, am Xbox 360, a PS3 and a DVD player.
No the PS3 already has built in wi-fi, so that wasn't an issue, but i didn't want to have to spend money buying a wireless card or adaptor on each of the 360, DVD player and PC. So I did some research and came across this Buffalo Ethernet Adaptor.
This enabled me to connect my DVD player, PC and Xbox 360 to this device with an ethernet cable which connected to our wireless router across the other side of the flat. BRILLIANT!
Setting this up was very easy. I had to connect it to the current router via an ethernet cable then run the included software to find it on the network, and then follow the onscreen instructions which consisted of security settings. And thet was it, I could move it anywhere within range and plug anything into its 4 ethernet ports.
I've had this for around 18 months now and have never had the signal drop ever. Which is absoluteley perfect.
Overall This suited my needs perfectly! And recomend it to anyone in a similar situation.
