Usually when I resolve a problem, there seems to be an outbreak of the same problem. Lately I resolved issues with wireless networking on several laptops and a desktop by disabling the power settings. Apparently when the laptop woke, it would not connect or was extremely slow on connecting. Disabling the power settings in both areas resolved the issue on all of the laptops and the desktop.
