Mac randomly stopping Internet

Solution 1:

Good call on not dumping the kitchen sink. The first step is to run Network Diagnostics - once when things work so you can see what it does and again when things are broken.

It will guide you through changes to make, so keep a short log of when you run it and what it has green/yellow/red and what changes are needed to fix each breakage.

Over time, you'll probably find a pattern to one thing breaking and can ask a more narrow follow up question.

To run the tool:

1. Open Finder
2. Use the Go manu - Go to folder
