Frequently asked internet speed questions

How do I test my current or upgraded speed?
Operating your device over a wired connection delivers the best speed.1 Testing speed over a wired connection ensures you have the most accurate reading of your internet service. Wi-Fi delivers good, but slower, speeds due to the wireless technology.

We provide a speed test site for you to check your current speed.

Note: Third-party sites may not be able to test AT&T Fiber speeds.

Perform a wired connection speed test
  1. Go to a computer that’s connected by wire to the AT&T gateway.
  2. Close any other applications on your device.
  3. Shut down any other Wi-Fi enabled devices including tablets, smartphones, computers, game boxes, and DVRs.
  4. Run the AT&T Internet Speed Test from a desktop or laptop wired to your gateway to see download and upload speeds.

Perform a Wi-Fi connection speed test

  1. Connect to your Wi-Fi home network using your desktop or laptop.
  2. Close any other applications on your device.
  3. Shut down any other Wi-Fi enabled devices including tablets, smartphones, computers, game boxes, and DVRs.
  4. Run the AT&T Internet Speed Test from a desktop or laptop connected through Wi-Fi to see download and upload speeds.

How do I improve my speed?
Sometimes a speed test you run may be slower than the speed you’ve purchased. In many cases you can take steps to improve your speed experience. A variety of situations influence your internet speed:
  • Make sure your equipment meets minimum requirements.
  • The age of your equipment – Having the latest equipment and software updates will improve speed.
  • The Wi-Fi technology embedded in your equipment – Older Wi-Fi security technologies, such as WEP, slow down internet speed and pose a security risk.  Set your devices to auto-update to the latest Wi-Fi standard technologies, such as 802.11ac or 802.11n. Check with your device manufacturer for specific information.
  • The number of devices sharing your network – Each device shares your internet connection, dividing the bandwidth and speed.
  • Your video set top boxes using internet bandwidth – Internet video and data use the same internet connection. Video takes priority over data. If your set top box is turned on, it may be using some of your available bandwidth, potentially slowing your Internet.

For the best speed experience, try these tips:

  • Update computer, tablet, and smartphone software with the latest device Operating Systems (OS).
  • Limit the number of devices using Wi-Fi by turning off ones that aren’t in use.  Examples are unused set top boxes, game systems, tablets, and smartphones.

Is my equipment slowing me down?

You may use a variety of internet-ready devices at home including desktops, laptops, tablets, smartphones, and smart televisions. Each device has a maximum connection speed to the Internet. Two devices tested from the same area may not have identical speed test readings because of differences in hardware and software capabilities.

Older computers may not be capable of operating at Fiber speeds. We know it's a little complicated to check all of your system's capabilities. Check our tips below on how AT&T ConnecTech can assist.
  • Network Interface Card - Ensure your network interface card is gigabit capable.
  • Windows OS - Ensure you have the latest 64-bit operating system available for your PC. Windows Vista, Windows 7, Windows 8, and Windows 10 are all Fiber capable.
  • Mac OS - OS 10.6-10.11 are Fiber capable.

The Wi-Fi technology embedded in your devices impacts the speed you experience, even on the Fiber network.
  • Newer smartphones and tablets - iPhone, iPad, and most Android devices are enabled with 802.11n Wi-Fi technology, and typically connect at 50-80Mbps speeds.
  • Laptop computers - Most new laptops are enabled with 802.11n Wi-Fi technology and operate at similar speeds as smartphones and tablets. Test speed using a wired connection for the best results.

Older Wi-Fi enabled devices operate more slowly and may affect your overall home Wi-Fi speed experience. The good news is that Wi-Fi technology is advancing rapidly. Next generation devices that incorporate advanced Wi-Fi capabilities like 802.11ac will provide faster Wi-Fi speeds. AT&T has enabled Fiber with 802.11ac technology in select gateways.

For the best speed experience, try these tips:
  • If you have an older network card, upgrade to a newer card that supports 1Gbps.
  • If your smartphone or tablet is older, consider upgrading to more powerful, speed-friendly Wi-Fi devices (with 802.11n or 802.11ac Wi-Fi technologies).
  • Call ConnecTech at 855-525-1840 for repair support that can pinpoint ways to solve your home network issues. Use promo code Fiber.
  • Microsoft Windows users can download the PC Maintenance Toolbox  to run the PC power test.
  • Mac users can download the Mac Maintenance Toolbox.

How do I get the most out of Wi-Fi?

Many things impact your in-home Wi-Fi experience, including walls, obstructions, and nearby Wi-Fi devices, especially older, slower devices. Cordless phones on 2.4GHz may also interfere with your connection. In addition, the operating systems and age of your devices could contribute to poor performance and pose a security risk.

For an improved Wi-Fi experience, try these tips:
  • Remove obstacles between your device and your router or gateway.
  • Change the location of the gateway to avoid unseen obstacles such as studs and metal pipes in walls. Mirrors and glass also affect Wi-Fi performance.
  • The distance from your gateway or Wi-Fi extender affects your Wi-Fi speed performance. The closer you move your device to your gateway or extender, the better the speed.
  • Older Wi-Fi security technologies, such as WEP, slow down internet speed and pose a security risk. Set your devices to auto-update to the latest Wi-Fi standard technologies, such as 802.11ac or 802.11n.
  • Place your equipment on an elevated surface, such as a desk or shelf, and never on the floor.
  • Purchase a Wi-Fi extender to improve coverage in your home.

Why do many websites and video streaming services run slower than expected?

Not all websites operate at 1 gigabit speeds. Many users visit a site at the same time, often causing the website to slow, especially during heavy traffic times like Black Friday. Even some third-party speed test sites cannot accurately test speeds on the AT&T Fiber network.

In addition, the manner in which website content providers connect to the Fiber network matters. Because websites and video streaming services choose the network paths, speed, and capacity by which they connect to the Fiber network to deliver their service, your experience of their service may vary, and may slow during busy periods.

Your AT&T Fiber service provides an outstanding high-speed experience when you visit multiple websites on multiple devices at the same time. Remember, it's essential you understand the speeds enabled by the hardware and software of your PC, smartphone, or tablet.
