    This is what I considered in the first place except that I am
    considering to make the connection between the laptop and the desktop
    wireless. The laptop has a built-in WLAN card (Prism 802.11g). However
    I am still uncertain about the performance I should expect, between the
    room where my desktop is placed and the room I (want to) use the laptop
    mostly is my kitchen, and I have read in several places that the
    performance of a wireless connection will drop dramatically when the
    signal has to pass through several walls and even more when the signals
    passes near a microwave-oven. Unfortunately this is exactly the case in
    my apartment.

    Solution 2.2 is more flexible, but doesn't it require two IP-adressess
    from the ISP? If so this option isn't suitable for me without getting a
    more expensive contract with my ISP.

    Thanks for the explanation!
