1. No Internet Connection

1.1. Check Physical Connections Ensure all connections are secure and correctly plugged in:

• Coaxial Cable: The coaxial cable should be tightly connected to both the wall outlet and the modem. Look for any loose or disconnected ends.
• Ethernet Cable: Verify that the Ethernet cable is firmly plugged into both the modem and your router or computer. If you have multiple Ethernet ports, ensure you are using the correct one.
• Power Cord: Check that the power cord is fully connected to both the modem and the power outlet. If you’re using a power strip, ensure it’s turned on and functioning.

1.2. Restart Your Modem A simple reboot can often resolve connectivity issues:

1. Unplug the modem from the power source.
2. Wait 30 seconds to 1 minute.
3. Plug the modem back in and allow it to restart. This refreshes the modem’s connection with your ISP.

1.3. Check Service Status Confirm if there’s a service outage:

• ISP Website: Visit your ISP’s website to check for outage alerts or service status updates.
• Customer Support: Call your ISP’s customer support for live updates and assistance if you suspect a widespread issue.

1.4. Verify Modem Lights Understanding LED lights can help diagnose the issue:

• Power Light: Should be solid. If off or blinking, check the power connection and try a different power outlet.
• Online Light: Indicates the modem’s connection to the internet. If off or blinking, there might be a connectivity issue with your ISP.
• Ethernet/Wi-Fi Lights: Ensure these lights are on when devices are connected. If they’re off, check the connections and device settings.

2. Slow Internet Speed

2.1. Test Your Speed Measure your internet speed to identify if it’s below expectations:

• Use reliable speed test tools like Speedtest.net to gauge your actual speeds.
• Compare results with your ISP’s plan specifications to determine if there’s a discrepancy.

2.2. Check for Interference Physical and electronic interference can impact speed:

• Placement: Position your modem in an open area, away from walls and large metal objects that could block signals.
• Other Devices: Keep the modem away from devices like cordless phones, microwaves, or Bluetooth devices that can cause signal interference.

2.3. Update Firmware Firmware updates can enhance modem performance and security:

• Access Firmware Settings: Log into your modem’s web interface using its IP address (often 192.168.100.1). Check for firmware update options.
• Download and Install: Follow instructions on the Arris website or your modem’s interface to install any available updates.

2.4. Optimize Placement Proper placement can maximize performance:

• Elevate the Modem: Place the modem on a shelf or table rather than on the floor to improve signal distribution.
• Avoid Obstructions: Keep the modem in a central location, away from furniture and other obstructions that could impede signal strength.

3. Frequent Disconnections

3.1. Inspect Cables and Connectors Ensure all cables and connectors are in good condition:

• Inspect for Damage: Check for visible damage on cables. Replace any that are frayed or worn out.
