I have been working with Spectrum regarding internet drops. Spectrum Rep. suggested that the modem/router needs an update. Spectrum cannot update the software on any other modem then theirs. Is there an update for this model?  Has anyone else had this issue? Thank you.

Under DOCSIS standards, firmware updates for cable modems must be distributed by the service provider, and end-users cannot manually install updates like other network-enabled devices.

ARRIS develops the software updates and provides them to service providers, who then qualify, test, and distribute them to devices on their network. ARRIS has limited control or visibility over this distribution process.

 

Aside from firmware updates, we recommend isolating the issue by connecting a computer directly to the gateway using an Ethernet cable. This helps determine whether the internet drops occur only on Wi-Fi or also on wired connections.

Ensure the gateway is placed in an elevated location, away from interference sources such as concrete walls or microwave ovens.

Additionally, check the cable signal levels within the gateway, as levels outside the acceptable range can cause rebooting or connectivity issues. When signal levels are within the recommended range, the gateway can maintain a stable, high-quality internet connection.

Please refer to the provided link for instructions on checking signal levels.

If the levels are not within the recommended range, contact your Internet Service Provider (ISP) to review and adjust them as needed.
