Optimize your Internet speed

Setting up your AT&T Internet for the first time? Trying to speed up your connection?
Learn about the factors that can affect Internet speed - and steps you can take to get the most out of your service.  

Do I have enough speed for what I want to do?

Every connected device in your home consumes some of your Internet speed. That’s why it’s important to have a plan that supports all the things you want to do. 

Activities that can affect speed

  • The number of devices connecting to the Internet at the same time 
  • Running multiple apps that connect to the Internet at once
  • Multiple devices streaming music, TV, movies, or videos
Have lots of connected devices? You may have outgrown your Internet plan. And we may offer speed plans that weren’t around when you set up your network. So, upgrading your plan could be an option.

What can I do to get the best speed from my network?

  • Place your Wi-Fi® gateway in a central location, off the floor and standing upright.
  • Avoid obstructions (like metal) and common sources of interference (like baby monitors and microwaves).
  • Move wireless devices closer to your gateway. The farther away they are, the weaker the signal and the slower the speed. Or, add a Wi-Fi extender to improve coverage throughout your home.
  • Use a wired connection for computers and laptops. Save your Wi-Fi signal for devices like smartphones, tablets, and home assistants.
  • Restart your gateway now and then to reset your connection.

Is my equipment affecting my speed?

Gateway good to go? Next, check your device, computer hardware, and software. How well they work when connected to your network impacts speed. 

If you haven’t already, try:

  • Turning off connected devices that aren’t in use. They may still be using speed.
  • Clearing your cache and cookies.
  • Using 1 firewall at a time.
  • Disconnecting from VPN or proxy servers.
  • Closing apps and browser tabs you aren’t using and exiting streaming apps when you’re done watching or listening.
  • Restarting devices regularly. 
  • Turning off auto updates on apps, gaming consoles, and PCs.
  • Updating anti-virus software, drivers, firmware, and computer and device software.
  • Keeping 10% of your hard drive free.
  • Updating PC, laptop, and tablet network cards.

What else affects speed?

Your geography and environment affect performance too! Speed slows: 

  • In areas with higher Wi-Fi use
  • In crowded neighborhoods and apartment buildings
  • During peak times

Other causes

  • Interference from neighboring networks
  • Wi-Fi device limitations
