Today when I was trying to print a document from the home printer (I rarely use the printer at home) I found out that it's off the network, furthermore I could not connect to the wifi router (192.168.1.1). But it worked when I booted to safe mode w/networking (I am using Win10). I am using Norton Security but the network issue persisted when I removed Norton from start up so that's not the culprit, I don't have any other firewall running. What could be the cause?
