Hello Douglas,
Something is not right with your pc if it keeps doing that on it’s own, you should uninstall your wireless driver and re install. Doing so will forget all wireless networks and require you to reconnect for the first time again before it remembers your settings. You can watch how someone does this here.
Follow up question, are you using a local account when you log into Windows OS? You may very well want to switch that online account over to local, you can click or tap here to see how.
