AT&T broadband network
AT&T delivers internet service to your home through copper or fiber wiring, depending on the service you purchased.
- DSL and lower broadband services are usually wired using copper.
- Most high-speed broadband services (IPBB) deliver internet via a hybrid fiber and copper network.
- AT&T Fiber delivers internet directly to your home using 100% fiber network.
Many factors inside your home affect the rate you send or receive internet data. These include:
- Age of wiring inside your home
- Distance between the gateway and your device
- Age and type of gateway or router
- Number of devices connected to the gateway
- Type of connection used
You can access your home internet through a wired Ethernet connection or a Wi-Fi connection.
- Wired connections use Cat5e or Cat6 cables plugged into the Ethernet port on your wall or gateway. These connections provide the best performance, consistently.
- Wi-Fi connections give you flexibility to move throughout your home, but it isn't as fast as a wired connection. You get the best Wi-Fi signal closest to your gateway, with fewer devices running.
- Wireless connections rely on your mobile service provider and are not part of your home internet service. To make sure you are not using your wireless data, make sure that your mobile phone or tablet are connected to your home network using Wi-Fi.
Type and number of devices
Internet devices come in all shapes and sizes. Each device has a maximum internet speed it can reach. But, that speed might not be as fast as your possible internet service level. For example, if your older laptop or tablet only supports 11Mbps and you have 1Gbps internet service, your laptop will never be able to reach the more than 11 Mbps.
When devices connect to your network, they each use a portion of your allotted speed. Multiple devices sharing your internet connection can affect the speed each device experiences.
TV and internet speed
In many cases, your TV and internet enter your home through the same terminal. Using both services at the same time consumes more available bandwidth and can affect your internet download speeds. For example, in certain speed tiers, watching multiple HD TV shows at the same time as very data-intensive internet usage, such as downloading an entire HD movie file on your laptop, may lead to reduced internet speeds as compared with such speeds when no other uses are placed on the home network.
Other networks and websites you visit
Even though you purchased a specific speed and the AT&T network is highly reliable, the websites you interact with may not provide their services at the same speeds. Things to consider as you surf websites:
- Websites may not have the same network speeds as you.
- Website server capacity can impact your Internet speeds.
- Website owners may use other ISPs to deliver content back to you. These network serving arrangements can also impact your Internet speeds.
- Visiting sites during their peak hours may also result in slower speeds.
Additional impacts on internet speed performance and speed test results
As noted, many factors can affect service speeds and speed test results. These include:
- Customer equipment
- Connection type
- Network issues
- Internet usage
In addition, protocol overheads, such as IP overhead in IP technology, diminish internet speed and speed test results. Overhead
(s) means the various control and signaling data (e.g., transmission control protocol (TCP)) required to achieve the reliable transmission of Internet access data.
