Windows 10: Wifi connection to printer suddenly stopped working on one of my laptops. Have to use usb...

Our Canon TS5050 prints wirelessly from my wife's windows 10 laptop, but my wireless connection to the printer via our router has suddenly stopped working and to print i have to plug it into the usb port. Any suggestions?

Win10 computer suddenly unable to access printer on home wifi

For some reason, the printer lasted less than 24 hours printing correctly, and now I again can't fix it, even by doing what "worked" before (Comment #6 upthread).

Regarding the static IP suggestion:

1. The printer is connected via USB to a Windows 7 computer on the home network. It's not on the network by IP address. Here is a screenshot of the printer port properties.
   
   
2. Although there ARE "headaches" as is said above, the vast majority of the other computers on the home wifi network, NEVER have had a problem printing to it. And this applies to computers that have run XP, Win7, Win10, and MacOS. For the most part until now, it's included the particular Win10 computer in question.
3. If I still might be able to give it a static IP address, will this affect the other computers that have been able to print to it fine using printer name?

 

Wifi suddenly stopped working - strange result


Wifi stopped working suddenly on my desktop. Now I have to connect with cable to the router but when I open Network Connections it still says the wifi is connected and working. The Ethernet connection has the name of the Wifi SSID.

If I open the details of the wifi connection it says there is no0 IPV4 or IPV6 connectivity although these are checked.

What has happened?

 

Win10 computer suddenly unable to access printer on home wifi

I was not able to ping the Win7 machine.

However headache-ridden this setup might be, I've had it for close to a decade, and remote machines - XP and Win7 and Win10 and Mac - have all easily printed from it. As did this, until it stopped working.

Two other questions:

1. How does one this SMBv1 issue you suggest? Sorry, not familiar with that term.
2. In looking at the event viewer, I am seeing near-daily critical errors from the machine being powered off by the button, versus the normal Windows shutdown (and will address with the family member who has the machine). Could this have been the cause of it suddenly not working? And any suggestions to look at and fix whatever may be wrong, if this is a possible cause?
