• Often unable to associate properly with a wireless router but works with other wireless routers

Solution: Disabled Quality of Service (QoS) on the router.  In some routers this may show as "WMM" or something similar.  Just disabling the QoS function altogether caused all wireless connection issues to go away.

Note: This issue occurred with my work laptop and my home wireless router.  The home wireless router worked with everything else - mobile phone, personal laptops, Apple TV, wireless tablets, XBox, wireless connected TVs, etc, etc.  Conversely, the work laptop worked with everything else: work wireless router, Internet sharing mobile phone, other routers, etc, etc.
