Instructions
Disconnect all other devices you have connected to the Internet. Having numerous devices, such as laptops and PCs connected to the Internet will take up bandwidth and reduce the speed of the Internet on your Xbox 360.
Contact Hughes Net and ask to upgrade your Internet service package to a higher speed. Although this will cost you more money per month, it will increase the speed of your Internet drastically.
Use an Ethernet cable to connect your router to your Xbox 360. Although having a wireless connection means you can play Xbox Live on your 360 from anywhere in your home, having a wired connection provides a better, and therefore faster, Internet connection.
