Updating to Big Sur 11.3.1, and experiencing on and off internet connection. Just connected to wifi but no connection from time to time. Already called the internet provider, no issue since my Ipad and iPhone can connect to the internet without any issue. Same with a windows laptop and android phone can connect properly. This issue is isolated to my macbook pro 13inch early 2015 and happened after I updated to Big Sur. Hoping will be resolved when I updated to 11.3.1, but it got worsen. please resolve this issue. thanks
