Technicolor C2100T CenturyLink Modem Router | VDSL2 Fiber Gateway

The renewed Technicolor C2100T is an all-in-one gateway for CenturyLink DSL and fiber internet, combining a VDSL2 modem, dual-band WiFi router, and VoIP phone support in a single device. At its price point it is one of the most affordable ways to stop renting a CenturyLink gateway, and its two phone ports make it the pick for households that still use CenturyLink home phone service.

Key Takeaways

• All-in-one CenturyLink gateway: VDSL2/ADSL2+ modem, dual-band WiFi router, and 2 VoIP phone ports in one device.
• Gigabit capable: dedicated WAN port supports speeds up to 1 Gbps and lets the unit act as a standalone router on GPON/fiber deployments.
• Also used on Brightspeed DSL in former CenturyLink territories (confirm with your provider before ordering).
• Renewed and tested, backed by a 90-day full coverage warranty and USA-based support.

Is the Technicolor C2100T Compatible with My Internet Provider?

The C2100T is approved for CenturyLink DSL service and supports both ADSL2+ and VDSL2 standards. It is also used on Brightspeed DSL in the former CenturyLink territories Brightspeed now operates. Its dedicated Gigabit WAN port additionally lets it serve as a standalone router on GPON/fiber deployments. Confirm compatibility with your specific plan and address before purchasing, since deployment types vary.

The C2100T does not work with cable internet (Xfinity, Spectrum, Cox), Verizon Fios, AT&T service, satellite, or 5G home internet. It connects through a telephone-style DSL wall jack, not a coaxial jack.

Which CenturyLink Gateway Should You Buy?

We carry three CenturyLink-compatible gateways, and the right one depends on your line and priorities. The C2100T is the budget pick and the only one with VoIP phone ports, making it the choice for standard single-line DSL plans and homes with CenturyLink phone service. The Actiontec C3000A adds bonded (two-line) VDSL2 and G.fast support for plans delivered over a bonded pair. The GreenWave C4000LG is the newest of the three, with WiFi 6 wireless for homes packed with wireless devices. Not sure which line type you have? Your provider can tell you in one quick call.

Speed and WiFi Performance

The C2100T supports download speeds up to 1 Gbps through its dedicated Gigabit Ethernet WAN port. Simultaneous dual-band WiFi runs 802.11ac on 5 GHz and 802.11n on 2.4 GHz, with 2x2 MIMO antennas for extended range and fewer dead zones in medium to large homes. Four Gigabit Ethernet LAN ports handle wired connections for desktops, consoles, and smart TVs.

VoIP Phone Support

Unlike most replacement gateways, the C2100T includes two phone ports for CenturyLink digital home phone (VoIP) service. If you bundle internet and phone, this is the gateway that keeps both running without renting equipment. Households without phone service can simply leave the ports unused.

Security and Management

The C2100T features dual Ethernet firewalls (NAT and SPI) that identify and block malicious traffic before it reaches your devices, with WPA2, WPA, and WEP encryption support. A hardware WPS button connects wireless devices with one touch, and TR-069 remote management support lets your provider troubleshoot issues without a technician visit.

Save on Modem Rental Fees

CenturyLink charges around $15 per month to lease its gateway, which is $180 a year for equipment you could own. At its current price, this renewed C2100T pays for itself in about four months, making it the fastest payback of any CenturyLink gateway we carry.
