Windows 10: WiFi connection lost between start and logon

When I start my computer I can see at the Windows logo screen that the WiFi is connected to my hub but as soon as I log in it drops the connection and I have to connect manually by entering the "key" even though I have ticked the box that says "connect automatically".
Any ideas/solutions please?

My PC won't connect to a hotel WiFi.

The PC is connecting to the WiFi but the hotel logon website isn't popping up. I know the WiFi works as several other PCs connected with no problem. Any advice?

 

Windows 10 can't clear the pre-logon screen to access the Windows login screen

Windows 10 can't clear the pre-logon screen to access the Windows login screen. I ran diagnostics without errors. Mssaged with Microsoft Tech. Tried Safemode which stopped at the same point Windows pre-logon screen. Tech also suggested to do a PC reset
w/o impacting my personal files. The reset ran for 2 hours but with the same results. This is crazy as the pre-logon screen has 3 icons; wifi which is connected to my local wifi, ease of accessability and the power icon. it seems to me if i just could clear
the pre-logon screen I would be able to logon and continue using the PC. Any ideas? Has anyone else had this problem? This issue started for me 7pm Dec 1st.
