Lose wi-fi connection when PC is still on, but not being used.

Upgraded to Win 10 from win 8.1 in 2015
Several times during this time I lost my wi-fi connection after not using the PC for a while without shutting it down.
The network repair feature does not work, it only tells me what to do like checking cable and other connections.
Most of the time I get the connection again by several restarts.
Today I did three restarts and I tried to reset the network adapter.
When I click on the icon to reset, it does not do anything but stays on reset.(and state PC will restart) Finally after waiting 5 minutes, I shut down the PC and turned back on.
This time the connection was back on.
All this happen when the other PC is still connected and working.
Furthermore, the wi-fi connected printer get also disconnected for no apparent reason.
The only way to re-establish the connection is to disconnect and reconnect the power line.
PS. I also tried to fix it by disconnecting and reconnecting the modem.
Sorry for this long post.

Thank you for the quick reply. For some reason I could not find the same window with the Wi-Fi display as per your image. (I am really inept with PC stuff)
I took some screen shots, and one showed a power option. Perhaps you can tell from the snips if I need to do something else.

I'll try again.

I was in the device manager and the only thing I could see was the network adapters after expanding that one, this list came up, which one is the Wi-Fi? when I entered wi-fi, wifi and Wi-Fi in search, it could not find it

OK, done that. I hope that will eliminate future issues with the Wi-Fi disconnect.
How about the issue with the printer, would that be part of the same problem?
It also disconnect from Wi-Fi after not being used for a while.
The way I can get that fixed is by disconnecting and re-connecting the power cable.
