I certainly vote this topic as the worst posted thread of Christmas. Could you be any more vague?
What model of laptop and its specs, what model of desktop and its specs. More specifically what OS are they running. Xbox or xbox 360? And finally what wireless router? What is it you are having trouble with? Getting the router to connect to your ISP, getting the devices to find and connect to the router? It is impossible to answer where there is no specific question.
Can you please clarify the above please Rob so as we can help you as I'm sure you want to get it fixed quickly.
