There are times when you just need a quick connection at home or in a small office and setting up wireless can be a real hassle not to mention potential security issues. Instead you might consider ethernet over power aka eop. Advantages are that it is all plug and play, you can even use use house wiring as your medium. You will need at least two modules (on for each side of the connection,) i have seen a set of modules for under thirty dollars. That is not much more than the price of a good Nic.
Give it a try.
