I recently upgraded my Dell laptop to windows 11.  Since this occurred the wifi now disconnects after my computer sleeps from being unused for too long and does not reconnect even if I click on it manually - I keep being told there is a wifi connection, but no internet, which is not true, because my phone is connected just fine.  The only way to make it work again is to restart the computer. 

I've read similar articles where people have had this issue with windows 10, so have attempted to do the whole "Windows key + R, devmgmt.msc, network adapters, properties, power management tab" jam, but like others I'm also discovering that there is no Power Management Tab to uncheck "Allow computer to turn of this device to save power"

I'm not sure if when I was using windows 10 the wifi was powering down and was reconnecting automatically upon reopening after sleep, either way what is going on now since I've installed windows 11 is just annoying, I just want to be able to open my computer and go like I could on windows 10... do I need to reinstall wifi device drivers or something? anyone else experiencing this? any help would be appreciated.
