And I wonder
how many of these problems with Wi-Fi are due to incorrectly connected cables inside their computers. When I bought my Mac Pro, I was not using Wi-Fi to any large extent. However, when I installed an external HDD dock, I learned that many computers had been shipped with the connections switched. Since I changed those wiring connections, I have not had any Wi-Fi difficulties, and Wi-Fi is used ALL the time with smart phones and iPads and iPod Touch.
