After continued and further research on the wireless issues in Windows 8, the Intel Centrino Wireless-N 2230 (and others) network cards are not the problem. The wireless problems in Windows 8 is a Microsoft problem. There are other network card manufacturers (brands and models) that are also experiencing same type of problems in Windows 8. When there are other computers (desktops and laptops) connecting to and using the wireless connection without any problems, including the same type of or similar network cards, the problem is in Windows 8.
Based on my research and findings with trying to keep wireless connection on the Windows 8 laptop, the problem is not with the wireless card driver, it is in Windows 8.
