Hi there! Sorry to hear you are having network issues, based off what you are telling me, this sounds like a software issue rather then a hardware issue. I would first off run a troubleshooter using the steps below by doing the following:

Apple menu > System Preferences and click Network. Click Assist me, and then click Diagnostics. The Network Diagnostics utility will guide you through a series of questions and tests, ranging from checking your ethernet or Wi-Fi connection to network configuration and DNS servers.

To sum up the word jargon, the troubleshooter will see if there are any issues with your network configuration. Please let me know what happens!
