Windows 10: No wifi networks showing up after moving computer upstairs.

I recently moved my computer upstairs and now no wifi networks are showing up. Before, when I was downstairs I had ethernet, but I could still connect to wifi if I wanted to. Now, no wifi networks are showing up when I try to connect to wifi? Anyone know the issue?

Cannot browse upstairs PC from Downstairs


I can see both Windows 10 PC's listed in Windows Explorer (under the Network tree on the left hand panel).
I can browse both computers from the upstairs computer.
I cannot browse the (Ethernet wired) upstairs computer from my downstairs (wireless) computer.
The upstairs computer first asked for my downstairs Windows login, which I gave, and I was able to browse my downstairs PC from upstairs.

There are two accounts on the upstairs computer and I can access both after entering their individual credentials. When I try to browse the upstairs computer from downstairs it prompts for the upstairs computer's username and password (for some reason the name of my downstairs PC is listed as the domain in the popup window). The username/password combo is rejected. I've tried every credential used on the upstairs PC but none are accepted.

I opened the Credential Manager and there are no Windows credentials listed on either PC. I added a credential to the upstairs PC but I still wasn't able to browse it from downstairs.

If I can't browse the upstairs PC from downstairs then I don't want the upstairs PC to be able to browse my downstairs PC. However, I can't find a way to retract whatever permission I gave the upstairs PC. Upstairs users have free reign to browse my User and Public folders.

I'd appreciate any help to allow me to access the upstairs PC or to force the upstairs PC to enter my credentials for access as before. Thanks.

 

Wifi Networks not showing

On my Laptop if I wanted to change the wifi connection I would always see a list of the available networks when I selected the Wifi icon on the task bar.
Since the last major update to Windows 10 I find that when I select the wifi icon I only see the current connection





To see other networks within range I have to open the 'Network settings' and choose 'Show available networks' - then they show up.





Does anyone have any explanation for this - or possibly a 'fix' to show them all from the taskbar again.

 

ethernet computer does not show wifi computer in file explorer network list

My desktop computer is connected to my router with ethernet & does not show my WiFi connected laptop computer in the file explorer network list in the left pane. The desktop computer does list itself in the network list. The laptop shows both computers
in its network list. This worked a couple weeks ago before a windows 10 update was done on both computers. I've tried just about everything with no luck. What could be the problem?
