MacBook Pro keeps losing connection

My new MacBook Pro loses Internet connection from time to time (2-3 times a day); it looks like it's still connected to the network, but when I run the diagnostic the ISP-Internet-Server indicators are red. (It's not the network because all other devices work fine). Restarting or (as I discovered today) running the diagnostic tool to the end fixes the problem, but it's very annoying to have to do that, especially in the middle of a Skype call! Any ideas on how to fix other than take it back to the store and hope for the best? Thanks!

MacBook Pro with Retina display, macOS Sierra (10.12.6)

I would try resetting your NV/PRAM. To do this, hold the Cmd + Option + P + R keys and then power on the machine. It will begin to start then restart. You should hear the machine chime twice. Once it chimes twice, release the keys and allow it to boot. For more info, see: https://support.apple.com/en-us/HT204063


If that doesn't work, I would try safe booting. To do this, hold the Shift key at startup. It may take a little longer to boot, but once it boots, see if the issue persists. If not, just try restarting the system normally. Sometimes, a safe boot will self-correct the problem.


If neither of these work, I would take it to an Apple store or an AASP (Apple Authorized Service Provider) to have them run hardware diagnostics on it and check the connection between the wifi card and the logic board to see if it's loose.


Best of luck!
