5. Setup and Installation
Follow these steps to install your ARRIS Touchstone TM804G modem.

- Connect Ethernet Cable: Connect one end of the Ethernet cable to one of the ETHERNET ports on the modem and the other end to your computer's network port or your wireless router's WAN/Internet port.
- Connect Telephone Lines: If using telephone service, connect your telephone(s) or home telephone wiring to the TEL1, TEL2, TEL3, or TEL4 ports on the modem using standard RJ-11 telephone cables.
- Connect Power Adapter: Connect the power adapter to the POWER port on the modem and then plug the adapter into an electrical outlet.
- Power On: The modem will automatically power on. Observe the front panel indicator lights. The POWER, DS, US, and ONLINE lights should eventually turn solid green, indicating a successful connection to the cable network and internet. The TEL lights will illuminate when telephone lines are active.
- Activate Service: Contact your Internet Service Provider (ISP) to activate the modem. You will need to provide them with the MAC address and serial number, typically found on a label on the bottom or back of the modem.
Important: Do not connect the modem to a power outlet until all other connections are made.
6. Operating Instructions
Once the modem is successfully installed and activated, it operates automatically.
- Internet Access: Any device connected via Ethernet to the modem (or through a connected router) should have internet access once the ONLINE light is solid green.
- Telephone Service: If your service plan includes VoIP, connected telephones will have dial tone and function once the corresponding TEL lights are solid green.
- Monitoring Status: Refer to the front panel LED indicators (Section 4.1) to monitor the modem's operational status.
7. Maintenance
- Cleaning: Keep the modem clean and free of dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or aerosols.
- Ventilation: Ensure the modem is placed in a well-ventilated area to prevent overheating. Do not block the ventilation holes.
- Firmware Updates: Firmware updates are typically managed automatically by your Internet Service Provider. Do not attempt to manually update the firmware unless instructed by your ISP.
- Restarting the Modem: If you experience connectivity issues, try restarting the modem by unplugging the power adapter for 10-15 seconds and then plugging it back in.
- Factory Reset: The recessed RESET button on the rear panel can be used to restore factory default settings. This should only be done if instructed by your ISP, as it will erase all custom configurations. To perform a factory reset, use a paperclip to press and hold the RESET button for at least 10 seconds.
