I became a Mac convert about three months ago, and since that time I have been very happy. However, I've noticed something aboout the PowerBook antenna. To me it seems abysmally weak. I have cable internet and a Linksys router that I recently equipped with a high-gain antenna, but it is not helping at all. I fail to see how the Linksys router would be the problem. After all, a router is a router. Thus, my thoughts turned to the internal antenna. I was originally going to buy an external signal booster to attach to the PowerBook, but, as silly as this may sound to some, I don't want those bulky things destroying the sleek feel of the laptop. I am now thinking of having someone take apart the laptop to insert a high-power internal antenna. Thoughts?
