CenturyLink Internet Speeds and Speed Test FAQs
The graphs shown above are the CenturyLink speed test results based on thousands of user speed tests. The results measure your home network and the broader CenturyLink network.
If you’re getting a surprisingly low-speed result, try plugging your computer or laptop into the router with an Ethernet cable, or place it close to the router to avoid interference. The above averages trend low due to the large number of speed tests being run as part of the diagnostics process for home networking issues.
CenturyLink Speed Tiers
CenturyLink speeds are split into three plan tiers: Simply Unlimited Internet (DSL), Simply Unlimited Fiber 200, and Fiber Gigabit.
| CenturyLink Speed Tier | Download Speeds Up To | Upload Speeds |
|---|---|---|
| Simply Unlimited Internet | 100 Mbps | 30 Mbps |
| Simply Unlimited Fiber 200 | 200 Mbps | 200 Mbps |
| Fiber Gigabit | 940 Mbps | 940 Mbps |
More customers are choosing fiber internet plans as this new and advanced connection type delivers fast download speeds, resulting in less latency, unlimited data, and faster loading times. That said, CenturyLink still offers DSL internet through its Simply Unlimited Internet plan, which offers download speeds up to 100 Mbps. This is a decent speed to stream movies and shows in HD on top of occasional internet surfing.
CenturyLink Download Speeds
Generally, download speeds are faster than upload speeds, but CenturyLink’s fiber internet plans have symmetrical speeds. This means its upload speeds match the download speeds. Be aware that the more you use the internet for streaming, online gaming, and overall heavy internet usage, the higher the download speeds you’ll probably need. This is especially the case for large households with multiple users connecting to the internet on multiple devices.
CenturyLink Upload Speeds
Upload speeds aren’t as important as download speeds unless you’re big on uploading large files and photos. It’s highly recommended that you sign up for a plan with symmetrical speeds if it fits within your budget.
CenturyLink Speeds vs. Satellite Speeds
As a DSL and fiber internet provider, CenturyLink is on par with the competition that offers these connection types. CenturyLink plans have faster speeds than satellite internet providers like Viasat and HughesNet, whose download speeds average between 25-100 Mbps. Most importantly, you won’t overpay for slow internet with low data caps – common characteristics of satellite internet plans.
CenturyLink Speeds in Context
CenturyLink speeds aren’t the fastest in the market, as some providers only offer download speeds up to 5 Gbps. However, that just means it has room to grow as it makes its way to becoming one of the fastest internet providers in the U.S.
