Query: This does not work--I have 2 of them

I love apples, but I warn you not to buy this product. I bought 2 for 2 differnet ibooks in 2 different locations. The wireless worked fine for the first 6 months, but has stopped. The problem is most likely in the software, since the problem happened in both systems. There is an Apple discussion board on-line through Apple that has over 500 posts discussing this issue. Apparently Apple has no idea about how to fix it. So, save your money and don't buy this product. I wish it would work--but it does not.
