Installation and Equipment: CenturyLink vs. Frontier Fiber
CenturyLink Installation
Self-install for DSL (modem shipped free). Fiber requires pro install (free, 2-3 hours). Equipment details: Wi-Fi router included on fiber plans. DSL modem shipped free.
Frontier Fiber Installation
Professional installation required (2-4 hours). Free standard installation on most plans. Appointments within 3-7 business days. Equipment details: WiFi 6/6E router included free on all plans. No modem rental fees.
The installation experience can vary significantly between providers. Professional installation means a technician handles everything -- running cables, mounting equipment, configuring your router, and testing speeds -- but requires scheduling a visit during a service window. Self-installation kits let you set up on your own schedule but may require basic technical comfort with connecting cables and following app-based setup instructions.
Tips for installation day: clear the area where equipment will be installed, ensure someone 18+ is home during the appointment window, test your speeds immediately after setup using a wired connection, and save your technician's contact information in case of follow-up issues.

When evaluating customer service, consider these factors: response time during outages, availability of local service centers for in-person help, quality of self-service tools (mobile app, website, chatbot), whether technical support is available 24/7 or only during business hours, and whether you can reach a human representative without navigating lengthy phone trees. Providers with both 24/7 phone support and a robust self-service app generally deliver the best overall support experience.
Coverage and Availability
CenturyLink serves 36 states (regional). Frontier Fiber covers 25 states (regional). Coverage overlap may be limited since these providers serve different regions, so confirming availability at your specific address is the essential first step.
Even within a provider's service area, not all addresses receive the same technology or speed tiers. For example, a provider may offer fiber at one address and only DSL a few blocks away. Always check availability at your exact address through each provider's website or by calling their sales line. Some addresses may only have one of these two options available, which simplifies the decision considerably.
Best For: Who Should Choose Which Provider?
Best for Gaming
For online gaming, low latency and consistent speeds matter most. Fiber connections from CenturyLink provide the lowest latency (1-5ms ping), making them ideal for competitive online gaming where every millisecond counts. Cable connections typically deliver 10-30ms latency, which is adequate for casual gaming. Wireless and satellite connections generally have higher and more variable latency. For competitive titles like Fortnite, of Duty, and Valorant, latency under 20ms is ideal. For casual gaming, anything under 50ms works well.
Best for Streaming (Netflix, YouTube, Disney+, Hulu)
4K streaming requires approximately 25 Mbps per stream, while standard HD needs about 5 Mbps. A household streaming on 3-4 screens simultaneously needs 100-150 Mbps minimum. Both CenturyLink and Frontier Fiber offer plans that exceed this threshold. Neither provider has data caps, so you can stream as much content as you want without worrying about overage charges or speed throttling. If your household has multiple streaming subscriptions and everyone watches simultaneously, prioritize plans with at least 300 Mbps.
Best for Working from Home (Remote Work)
Remote work requires reliable speeds for video conferencing (5-10 Mbps up/down per call), cloud file access (Google Drive, Dropbox, OneDrive), and VPN connections. Upload speed is critical here -- fiber connections from Frontier Fiber offer symmetric upload speeds, making them significantly better for video calls, screen sharing, and uploading large files. With symmetric fiber, your Zoom calls will be crisp and your file uploads fast. If multiple household members work from home simultaneously, plan for at least 50 Mbps per remote worker.
Best for Large Families (5+ Users, 10+ Devices)
Households with 5 or more people using the internet simultaneously should target plans with 500 Mbps or faster downloads. CenturyLink offers plans up to 940 Mbps, while Frontier Fiber goes up to 5 Gbps. Consider the total number of connected devices -- the average U.S. household now has 15-20 internet-connected devices including smart TVs, phones, tablets, laptops, gaming consoles, smart speakers, security cameras, and smart home devices. Each device consumes bandwidth even when not actively in use.
Best for Budget-Conscious Shoppers
CenturyLink starts at $50, while Frontier Fiber starts at $49.99. Factor in equipment fees, installation costs, and potential price increases after the first year when calculating the true 2-year cost of each provider. To find the best value, calculate the cost per Mbps: divide the monthly price by the download speed to see which plan delivers the most bandwidth per dollar.
