2. Connect Ethernet Cable: Connect one end of the Ethernet cable to an Ethernet port (LAN 1 or LAN 2) on the back of your SB8200-RB modem. Connect the other end to the WAN/Internet port of your Wi-Fi router or directly to your computer's Ethernet port.
3. Connect Power: Plug the power adapter into the Power port on the back of the modem, then plug the other end into an electrical outlet. The modem will begin its startup sequence.

Troubleshooting

No Internet Connection:

• Check Cables: Ensure all coaxial, Ethernet, and power cables are securely connected.
• Power Cycle Modem: Disconnect the power adapter from the modem, wait 10-15 seconds, then reconnect it. Allow the modem to fully restart (this may take several minutes).
• Check LED Status: Refer to the "Operating" section to interpret the LED indicators. If the "Online" LED is flashing or off, the modem is not connected to your ISP's network.
• Contact ISP: If the issue persists after checking connections and power cycling, contact your Internet Service Provider. They can verify your service status and modem registration.

Slow Speeds or Intermittent Connection:

• Test Directly: Connect a computer directly to one of the modem's Ethernet ports (bypassing your router) to determine if the issue is with the modem or your router.
• Check for Interference: If using Wi-Fi (via a separate router), ensure your router is placed optimally and not experiencing interference.
• ISP Service Check: Your ISP can perform diagnostics on your line to identify any signal issues that might be affecting your speed.

Maintenance

To ensure optimal performance and longevity of your ARRIS SB8200-RB modem:

• Keep Ventilated: Place the modem in a well-ventilated area, away from direct sunlight and heat sources, to prevent overheating.
• Clean Regularly: Gently wipe the exterior of the modem with a soft, dry cloth to remove dust. Do not use liquid cleaners or aerosols.
• Firmware Updates: Firmware updates are typically managed by your Internet Service Provider. Ensure your modem is connected and powered on to receive these updates automatically.
