Honestly speaking, I don’t know much about bluetooth!

However, I think I may need it soon 

Now here is my problem. I use computer in my bedroom. But my telephone connection is in my living room. So, when I connect to net, I need to attach a 20 ft long cable running between rooms!

So, I wonder whether I can make the connection via bluetooth.

Please advise, what components I need to attach to my computer, and how do I convert my phone connector socket to bluetooth.

Thanks very much for advice.
