Partition recovery

IE7. Now. I want to allow ONLY my laptop to connect wirelessly to the wireless Linky then thru the Wired Linky to the net. What the best way to do that in regards to security ( there are other wireless networks in the neighborhood also )? Links? Suggestions? I assume turn on WEP or WAP and use MAC filterin. I also use magic jack. If you experience dropped calls on your router, I suggest you flash your linksys router to dd-wrt or tomato firmware if your router supports it. Name.
