Zyxel Q1000Z Overview
The Zyxel Q1000Z is a VDSL2 modem and wireless router in one, built for CenturyLink internet service. With four Ethernet ports, a USB port, a phone port, and a VDSL line port, it handles your whole home network without any extra equipment, which makes it one of the best budget CenturyLink compatible modems available.
The Q1000Z supports heavy simultaneous use like streaming video and online gaming, and its two 5 dBi antennas improve WiFi speed, reduce dead zones, and extend coverage. Dual firewalls (NAT and SPI) identify and block malicious traffic before it reaches your devices.
Key Features
- VDSL2 modem and wireless router in a single device, so no extra equipment is needed
- 802.11n WiFi with data rates up to 300 Mbps and two 5 dBi antennas for extended coverage

Easy Activation and Setup
Like other CenturyLink modems, the Q1000Z can be fully activated without speaking to customer service.

If you are installing a unit that was previously in service, perform a factory reset before connecting so any old credentials are cleared. Either way, you will be online quickly.

Will this work with my internet company?
The Zyxel Q1000Z is primarily used with CenturyLink service in most areas. CenturyLink only activates certified modems, so a tested, compatible unit like this one matters more than it would on cable internet.
Always contact your service provider's customer service before placing your order to confirm this model will work with your line type and service plan. Some service plan speeds may not be supported.
Skip the Monthly Rental Fee
CenturyLink charges about $15 per month to lease a modem, roughly $180 per year. Owning a professionally refurbished Q1000Z means the modem typically pays for itself within a few months of your first bill.
Setup and Activation
- If the unit was previously in service, hold the reset button to perform a factory reset and clear old credentials.
- Connect the included DSL/phone cable from your wall jack to the modem's DSL port.
- Plug in the power supply and wait for the DSL light to go solid.
- Connect a computer or phone to the WiFi network on the label, or by Ethernet.
- Follow the prompts on CenturyLink's online activation portal, or call CenturyLink customer service to activate for you.
Frequently Asked Questions
Is the Zyxel Q1000Z compatible with CenturyLink?
Yes, the Q1000Z is primarily used with CenturyLink DSL service in most areas, typically on legacy copper lines. Confirm with CenturyLink customer service before ordering, since line types and supported speeds vary by address.
Can I activate the Q1000Z without calling CenturyLink?
Usually, yes. CenturyLink's online activation portal can provision and activate the modem in around 30 minutes. Calling customer service remains an option if you prefer a guided activation.
What speeds does the Q1000Z support?
The Q1000Z is a VDSL2 gateway used on CenturyLink plans up to about 40 Mbps. Actual speeds depend on your plan and line quality, so verify your tier with CenturyLink before ordering.
Does the Q1000Z have WiFi?
Yes, a built-in single-band 2.4GHz 802.11n network at up to 300 Mbps. If you want dual-band or longer range WiFi, you can connect your own router or an extender through one of the Ethernet ports.
Can I use my own router with the Q1000Z?
Yes. The Q1000Z can be placed in transparent bridge mode so a router you own handles WiFi and routing, or you can simply plug a router into a LAN port and let the Q1000Z handle the DSL connection.
Is a CenturyLink DSL modem still worth buying in 2026?
If your address runs on a CenturyLink copper DSL line, yes: the Q1000Z is an inexpensive way to end the rental fee on a lower speed plan. CenturyLink is shifting many areas to Quantum Fiber, which uses different equipment, so match your modem to your line type with our CenturyLink modems by speed tier guide.
