The Arris DG1670A Touchstone DOCSIS 3.0 Data Gateway is a 16x4 modem router combo that is compatible with Spectrum and Time Warner Cable. We recommend this model for anyone looking for an inexpensive modem router combo that works with Spectrum and Time Warner. This model's performance is great for homes up to 1700 Sq Ft based on extensive testing from our technicians. If your home exceeds that size, ModemGuides technicians may recommend attaching a range extender to cover any dead zones or upgrading with an added router. Our technicians love this model since it's easy to activate without assistance from your service provider, and has reliable dual-band WiFi built into the device. No need for extra equipment and your network is up in a matter of minutes.
The DG1670A combines a 4-port Dual-Band Gigabit Router and 802.11n wireless access point with two independent simultaneously operating 802.11n radios into a single device capable of support both home and small office applications. The added 5GHz wireless band helps extend high speed signal to the further reaches of your home, and helps reduce spotty coverage. The goal of this is to help reduce dead zones & make your network as fast & reliable as possible, from anywhere in your home.
In addition to the added 5GHz wireless band, this model also features improved internal antennas to help boost your WiFi. The improved antennas provide increased performance while also improving upon the design from previous generations of Arris products.
The DG1670 distinguishes itself with capabilities that minimize the need to contact your internet provider. We know giving them a call can take an entire afternoon in some cases. Because of this, we highly recommend the DG1670 since many of it's settings can be accessed through this device's admin settings panel in minutes. Within the portal you will have access to Multiple provisioning methods (SNMP, Configuration File, Remote WebGUI access, TR069, and TFTP) which allow you to create a custom-designed setup.
This Arris modem is primarily used and is compatible with Spectrum, Charter & Time Warner Cable service in most areas. To verify that this model will work in your area, always contact your service provider's customer service prior to placing your order with us to confirm that this model will work with your service plan. Some service plan speeds may not be supported.
