The Actiontec C1900A is a high-performance DSL gateway designed to deliver a premium HD IPTV, gaming, and ultra-fast web experience. Built specifically for CenturyLink customers, this model supports pair-bonded VDSL2+, providing significantly faster wireless speeds and extended coverage compared to standard single-line modems.
Whether you are on a VDSL or ADSL network, the CenturyLink C1900A features an ultra-powerful hardware design. Its "Auto Fall Back" technology ensures seamless operation across VDSL2, ADSL2+, and ADSL2 networks. This versatility makes it an ideal future-proof solution—if your service plan changes, your hardware won't have to.
Stop dealing with dead zones. The Actiontec C1900A is enhanced with MU-MIMO Smart Antenna technology. Unlike standard routers that communicate with one device at a time, MU-MIMO allows the C1900A to communicate with multiple devices simultaneously, increasing whole-home coverage and reducing lag during peak usage.
Protect your data with 21st-century security features. The C1900A includes a fully customizable firewall with:
| Feature | Specification |
|---|---|
| Service Support | VDSL2 (Bonded/Single), ADSL2+, ADSL |
| Wi-Fi Technology | 802.11n with MU-MIMO |
| Ethernet Ports | 4x Gigabit Ethernet (LAN) |
This Actiontec modem is specifically optimized for CenturyLink DSL service. While it supports both VDSL and ADSL standards, we highly recommend contacting CenturyLink customer service to confirm that your specific local service plan supports the C1900A before purchase.
