- Type in Command Prompt to find that app.
- Select Run as administrator for the Command Prompt result.

- Next, input your PC’s IP address in your browser’s address bar and press Enter to bring up a router settings login page.
- Log in to your router settings page.
- Look for an MTU Size setting on a network tab.
