Seeing as this iMac is no longer new and I’m reopening this question. I don’t have much upgrade experience (dates to far back to count), so I would like to know what I can to to improve this Mac’s performance as I find it slower than my mid-2014 MacBook Air at times with multiple apps and Safari open.
Hello, Since when this happens you may have no internet access, first do one of these to have access: (1) Bluetooth tether to your cellphone. (2) Ethernet cable connect to your router - box Then do a Windows update and then your drivers via Device Manager. I had Qualcomm & Realtek network devices for my network, but I also updated all of my drivers . Restart the PC and still it didn’t work, though it solved lots of my other issues . So what worked??? (1) Disconnecting my router - box and reconnecting it And voila! My Asus PC could now see my box again.
