Quantum Fiber availability
Understanding Quantum Fiber’s availability requires a quick bit of background. Quantum Fiber is a CenturyLink sister company that offers fiber internet services. CenturyLink still offers fiber internet service, but at the moment, parent company Lumen is working to fully separate its internet services between Quantum (for fiber internet) and CenturyLink (for DSL internet).
Currently, Quantum Fiber is available in the following states:
Alabama
Arkansas
Arizona
Colorado
Florida
Georgia
Iowa
Idaho
Indiana
Kansas
Louisiana
Minnesota
Missouri
Mississippi
Montana
North Carolina
Nebraska
New Jersey
New Mexico
Nevada
Ohio
Oklahoma
Oregon
Pennsylvania
Tennessee
Texas
Utah
Virginia
Washington
Wisconsin
Wyoming
Quantum’s already completed this migration in many states. During our research, we checked old CenturyLink addresses in Colorado and Washington and got redirected to Quantum Fiber’s purchase prompt.
In practice, nothing separates Quantum and CenturyLink’s fiber plans. Both companies have the same internet plans, and CenturyLink has been migrating its fiber internet customers over to Quantum. That said, you’re not alone if you’re confused about the difference between CenturyLink and Quantum, but Lumen will eventually make this distinction moot.
Quantum Fiber equipment fees
If your address already has a Quantum Fiber hookup, you won’t have to pay an installation fee. But Quantum could be pricier if the ISP needs to do a new installation.
Quantum will cover up to $1,500 in installation costs, and the ISP says most jobs should cost less than $2,000. In these scenarios, you’ll get a full installation quote from Quantum before you choose to sign up for service.
For standard installations, you can rent a combo modem/wireless router for $15 per month on Quantum’s 500 Mbps plan. If you upgrade to the 940 Mbps plan, you can get it for free (it normally costs $200) or choose to use your equipment. We suggest buying your own wireless router instead of renting one since you’ll save on monthly rental fees.
