Ralston18 :
Are all other network functions and devices working correctly? I would expect so but have to ask....
First try running the built in Network Troubleshooter via a right-click on the wireless icon (usually located lower right screen corner).
Then run and look at the results of "ipconfig /all" on your PC. See what the adapter is "reporting" with regards to its current configuration and what you would expect to see.
Open up the PC, reseat the adapter, check all antenna connections.
Check the Event Viewer logs for errors or messages relating to or corresponding with the wireless "turn off". Some event, service, process change just before or at the time of the "turn off".
The objective is to narrow down the possibilities and identify some constant, repeatable, action leading to the loss of wireless connectivity.
