Remote connection to Windows 11 laptop - offline

Hi all, I hope you can help me. I posted this in a Teamviewer (remote access software) forum, but it's not very busy; so I am hoping maybe there is an issue on the Windows side someone is knowledgeable about.

I use Teamviewer (TV) personally to remote into my Mom's Windows 11 computer to do her maintenance, updates etc. For years, prior to Windows 11 even, she did not have Windows configured with a password. But now, there is someone else in her house, so I added a password to her Windows installation. The other thing unique to her system, I have a scheduled task to do a shutdown -r to restart the computer every morning at 6 AM, as from time to time she would do things with the computer that caused it to get locked up or hung, putting it in an offline state. I have had that working for years as well.

Once I added the Windows login password though, I found TV always showed as offline. I did some research when I was at her house yesterday, and I found a setting in TV that permitted remote Windows logins, that was not set - without it, the remote computer had to be logged in for remote access. I set it, and then in some tests I found I could connect remotely from my iPad, restart the computer remotely, and it still showed online - I could then log in with her Windows password. Problem solved, or so I thought!

This morning, the computer is offline. So I am thinking something is different when doing a scheduled task shutdown -r. Is there some other TV(if you know anything about it) or Windows 11 setting/configuration I need, to be able to get the computer to be online after a restart? Thanks!

One other point - she is in a building where they offer Comcast WiFi - she has no router, they do - but different than my router at home for example, she enters a user name and password to connect to her WiFi. It's a one time thing (ie credentials are stored), so if I click 'connect' on the network if disconnected it does not ask for credentials again. But is it possible that because a username and password is required, Windows dos not connect to the WIFi until someone is logged in?

Yes, that is part of using login names and passwords, things don't/can't happen until that is done.

Yet, when I did a remote restart several times yesterday by the Start Menu/restart, I was able to connect and log in - so the internet/wifi was connected then before a Windows log in?

It is possible for a restart of Windows to reconnect the Wireless/Wi-Fi, mine do but I still have to enter the password for Windows.

No it doesn’t have a problem letting me remotely log in with the Windows password if it’s connected to wifi- the problem is, it is not connected to wifi before the Windows login, when it does a scheduled task shutdown -r, I think.

Maybe it's the -r switch causing the issue?

I don’t see any issues, I have used this for a long time. From the documentation, -r looks fine?
