What do I need to change?
The first step is to go to the device manager and look for any warnings by TCP/IP
Then go to the little network icon bottm right and right click, to troubleshoot connection problems
Then you can try to type cmd in search by start menu. In cmd type ipconfig and look for any thing that looks like a problem. It should show that you are connected.
Is your compter getting a bad signal?
Try turning off A/V and firewall. Make sure you reconnect after the test.
