Brand New MacBook Pro with terrible Wifi

I bought a new Mac, literally yesterday, and the wifi has been crazy. After an extremely slow start up, the wifi worked like frozen syrup. It's fine on other devices, including the old, fully up to date Mac Pro.


https://discussions.apple.com/thread/7833692


After digging around, the above thread seemed like it provided a solution. Removing the listing files had no effect on any other program and the wifi speed went from barely working to working fine. Unfortunately, the files automatically download and replace themselves and, when that happens, the internet randomly slows down again. Removing the listed files restores internet speed.


When I contacted Apple Support, they freaked out - apparently the thread above is a 'third party'. They are unable to figure out what is going or why, and, despite the existence of the discussion above (and many others) claim no knowledge of any issues like this.


I have a brand new computer with wifi that only works sporadically and Apple's support thus far is to dump customers and rub their nipples.


Any help on this one would be appreciated.

The solution to dump the preference files is the brute-force 'club it on the head with a 2 by 4' equivalent of "set it up again from scratch". Both allow you to walk away from any pre-conceived notions.


The more civilized way is to set it up with one or more named "Network Location File" using this article -- do not take the default-name -- ALWAYS specify a meaningful mnemonic name.

Many user find that the problems are in their own "network neighborhood", not in the Hardware or settings on their Mac. To explore that, screenshot or transcribe the settings from a Wi-Fi snapshot, obtained by holding the Option key while clicking the Wi-Fi Icon on the menubar. it will be similar to this older one:



also, how many networks do you see?
