Hi, i have a macbook air early 2015 with Mac OS High Sierra just updated , after the update my wifi started to drop out randomly. If I turned wifi on and off, it would work temporarily but drop out again within 5 minutes but sometimes i have restart my Mac for wifi to turn on. When the connection drops out, no online services/connections work but my Macbook Air still says that I am connected with full bar. I have tried resetting all of my system preferences to remove old wifi settings, but had no luck. N:B: My Ipad and sansung tablet and even my iphone work well with no wifi dropping. It would be greatly appreciated if anyone could help me fix this!
