Windows 10: Dell Computer isn’t showing WiFi Networks

I live in an apartment building and my Windows 10 Dell computer was working perfectly until this morning when it would no longer show the apartment WiFi. I know that the WiFi is not the issue because my phone is connecting no problem and so are all of my roommates devices on the same network. I have tried running trouble shoots and have not been able to find an issue. Please help I need this computer to work.

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

 

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?
