Xtream by Mediacom Installation Options

Have you recently qualified or signed up for an upgrade or change to your service? While new customers can call a technician for installation support, Xtream powered by Mediacom also makes it easier than ever to self-install your own services if you're an existing customer. Offering live support, how-to videos, and other resources, Xtream is here to help get you connected to friends, family, and entertainment in no time.

If you qualify for self-installation, Mediacom will mail your kit after you upgrade or change your Xtream services. It will include all the equipment and instructions you need to set up your service. You can also often pick up a kit at a store near you.

Whether you're installing yourself or need assistance, you can explore all the installation support Mediacom offers here.

Understanding Your Xtream Equipment

Getting familiar with your equipment and the technical terms associated with it can help you troubleshoot issues and communicate more effectively with customer support. Here are the key terms and components you should know:

DOCSIS (Data Over Cable Service Interface Specification)

DOCSIS is the international standard for transmitting data over cable networks. The version number indicates the technology generation:

  • DOCSIS 3.0: Supports speeds up to 1 Gbps
  • DOCSIS 3.1: Supports speeds up to 10 Gbps (required for Xtream service)
  • DOCSIS 4.0: The newest standard, supporting even faster speeds

Your modem must be DOCSIS 3.1 or higher to work with Xtream powered by Mediacom. Older modems won't support the speeds and features of modern Internet service.

MAC Address (Media Access Control Address)

The MAC address is a unique identifier assigned to your modem or router. It's a 12-character code (like A1:B2:C3:D4:E5:F6) that helps Mediacom recognize your specific device on their network. You'll need this for:

  • Activating your modem
  • Troubleshooting connection issues
  • Registering equipment with customer service

You can find the MAC address on a label on your modem or in your device settings.

Coaxial Cable (Coax)

A coaxial cable is the round cable with a metal connector that delivers cable Internet and TV signals to your home. It screws into:

  • Wall outlets (cable jacks)
  • Your modem
  • Your cable box

Coaxial cables are designed to carry high-frequency signals with minimal interference, making them ideal for broadband Internet and cable TV service.

HDMI (High-Definition Multimedia Interface)

HDMI is the standard cable used to connect your cable box to your TV. It carries both high-definition video and audio through a single cable. HDMI provides:

  • Better picture quality than older connections
  • Support for 4K and HDR content
  • Audio return channel for soundbars and receivers

Most modern TVs have multiple HDMI ports. Make sure to select the correct HDMI input on your TV after connecting your cable box.

Ethernet Cable

An Ethernet cable provides a wired connection between your modem or router and your devices (computers, gaming consoles, smart TVs). Wired connections typically offer:

  • Faster speeds than WiFi
  • More stable connections
  • Lower latency for gaming and video calls

Ethernet ports look like wider phone jacks and are labeled "LAN" or have a network icon on your modem.

Renting vs. Buying Equipment from Xtream

Xtream Internet service requires a DOCSIS 3.1 modem (or higher). If you are tech-savvy, you may want to buy or use your own (click here for a list of supported retail modems). However, you can rent one from Mediacom for $15 per month. If your rented equipment stops working, Mediacom will typically replace it free of charge. Additionally, if or when the rented modem and router become obsolete, they will upgrade your equipment at no additional charge.

Common Cable Box Error Codes

If you see an error code on your cable box, here are the most common ones and their solutions:

  • Solution: Wait 10-30 minutes. If it persists, restart the box

Error Code: Ref Code S0600

Modem Won't Connect to the Internet

If your modem powers on but won't connect to the Internet:

  1. Check all cable connections: Ensure the coaxial cable is firmly connected to both the wall outlet and modem.
  2. Verify activation: Make sure you've completed the activation process through the online portal or phone.
  3. Restart your modem: Unplug the power cord for 30 seconds, then plug it back in and wait 5-10 minutes.

Slow Internet Speeds

If your Internet is slower than expected:

  1. Run a speed test: Conduct a speed test to measure your actual speeds.
  2. Connect directly to the modem: Use an Ethernet cable to bypass WiFi and test speeds.
  3. Check for interference: Move your router away from microwaves, baby monitors, and cordless phones.
  4. Limit connected devices: Disconnect unused devices to free up bandwidth.
  5. Restart your equipment: Power cycle both your modem and router.

  1. Verify WiFi is enabled: Check that the WiFi light on your router is on.
  2. Check your password: Ensure you're entering the correct WiFi password (found on the router label).
  3. Move closer to the router: Weak signals can prevent a connection.
  4. Restart the device: Power off your phone, computer, or tablet and restart it.
  5. Forget and reconnect: Remove the WiFi network from your device settings, then reconnect.

Cable Box Shows No Picture

If your TV displays no picture from the cable box:

  1. Check TV input: Ensure your TV is set to the correct HDMI input.

  3. Test the HDMI cable: Try a different HDMI cable or HDMI port on your TV.
