Testing 1 Gig Speeds

With speeds this fast, there are limitations experienced by all carriers and providers. Also, be aware that your speed will only be as fast as your device(s) and can be constrained by the processors, the network adapter, the operating system, the browser and the memory in your PC, Mac, iPad, Kindle, etc. 1 Gig speeds^ are to one device and require:
  • Your Computer: needs a Gig Ethernet port
  • Your Ethernet cable: 5e or better
  • Your Modem: needs a Gig Ethernet port
^ Tests run over a Wi-Fi connection may not represent your full broadband connection speeds. Learn about factors that can affect your Wi-Fi connection speeds.

Area of Concern
Solution
Your Computer
Your computer needs a Gig Ethernet port. There are other factors on your device that can affect your speeds like the operating system, processor, memory, network adapter, the browser and the number of apps you have running.

Recommended Computer Specifications:
  • Operating System: Windows 7 Pro 64-bit
  • Processor: Intel® Core™ i5-3320M CPU @ 2.60GHz (4 CPUs)
  • Memory: 16 GB
  • Network adapter: 1 Gig
  • Wireless*: 802.11ac connected @ 5 Ghz
*802.11ac has a theoretical speed of 1.3 Gbps and a real-world speed of between 70-100+ Mbps. Real-world speeds consider factors like interference and distance.
Your Ethernet Cable
The Ethernet cable has been evolving since 1985. As technology changed, different categories of Ethernet cables started being developed. Each category has a different maximum data transmission speed.

Category Cable Type* Max Speed
3 UTP 10 Mbps
5 UTP 10/100 Mbps
5e UTP 1 Gig
6 UTP or STP 1 Gig
6a STP 10 Gig
6 SSTP 10 Gig

*What is UTP and STP?
Your Modem
Your router's Ethernet ports and wireless radio need to be fast enough to handle your speed. Check out the "Ports" and "WiFi" column on the CenturyLink modem compatibility table to see what your device is capable of.

Recommended Modem/Router Specifications: *802.11ac has a theoretical speed of 1.3 Gbps and a real-world speed of between 70-100+ Mbps. Real-world speeds consider factors like interference and distance.

^The only CenturyLink modem that supports 802.11ac is the Technicolor C2100T (not available yet). Using 802.11ac requires the purchase of additional equipment like the D-Link AC1200.
Other Devices
If you have multiple devices using your high-speed Internet, your 1 Gig speed will be shared with those devices. Be aware of devices can eat up your speeds: other computers, gaming system, web enabled camera, DVRs, TV's, routers, VoIP phones, wireless printers, smart phones, Android, iPhone, iPad, Smarthome, Roku, Apple TV or Chomrecast.
Wireless Speeds
Speed tests performed over a wireless connection don't reflect your full connection speed. Keep in mind that wired connections are faster, more secure, more dependable and should be used whenever possible. With that in mind, we can show you some tricks to improve your wireless connection.

You can get the fastest Wi-Fi speeds possible in your environment by having a computer and modem/router both using 802.11ac* and connected @ 5 Ghz.
  • Your Computer: 802.11ac* Wi-Fi adapter connected @ 5 Ghz
  • Your Modem/Router: 802.11ac* Wi-Fi radio connected @ 5 Ghz^
*802.11ac has a theoretical speed of 1.3 Gbps and a real-world speed of between 70-100+ Mbps. Real-world speeds consider factors like interference and distance.

Troubleshooting Slow Speeds
1. Make sure you meet the following requirements:
  • Your Computer: has a Gig Ethernet port
  • Your Ethernet cable: is 5e or better
  • Your Modem: has a Gig Ethernet port (Check Ports column)
2. Let's try some stuff:

A. Make sure your equipment is set up correctly and that your modem is not filtered.

B. Power cycle your modem.

C. If you have another phone jack in the house connected to your Internet line, try connecting the modem to the other phone jack.

D. Run the speed test again.

E. If your speed test 'results' continue to be slower than the 'target speeds' contact Tech support.
