Chosen Solution

Hi, I’m having a problem with my 21.5inch 4k imac. Every time I wake the device from sleeping, the wifi doesn’t work, and I have to turn the wifi off and on every single time I turn it on. It’s not a huge problem, but I’d like to fix it. The problem doesn’t happen on Windows 10 with Boot camp. Thanks

Had the same machine in yesterday with the same problem. Ran virus check and it was clean. Installed Catalina and problem was solved.
