The following is a review checklist of wireless troubleshooting
Wireless enabled: Some laptops make it incredibly easy to turn wireless on and off.
Auto transfer rate: By default, wireless devices are configured to use the strongest, fastest signal. If you experience connectivity problems between wireless devices, try using the lower transfer rate in a fixed mode to achieve a more stable connection. For example, you can manually choose the wireless transfer rate. Also, instead of using the highest transfer rate available, try a lesser speed. The higher the transfer rate, the shorter the connection distance.
