AT&T Slow Wi-Fi - Fixes & Things to Know
Learn how to improve your Wi-FI speeds and why your internet is not working like you think it should
First, let's try some fast fixes to speed up your Wi-Fi.
|Restart the modem||Clear up the modem environment||Turn off devices not in use|
|This clears up the backend process that may be slowing your service down.||Electronics emit interference. Too many electronics can affect Wi-Fi performance.||Some devices may be pulling internet resources. Turning them off may stabilize speeds|
If the above does not work, we have more tips and information to help you understand why services may not be working as they should.
Optimize your settings
Just like your TV, the modem has different channels. One channel has the sports you like and another may have a favorite show. Others have nothing you want to watch or find useful. The Wi-Fi channels are the same, some work better than others. Some can help improve Wi-Fi coverage and speeds. Updating the Wi-Fi Channel is easy:
- Sign in to Smart Home Manager
- Once signed in, scroll to the "Let's Scan for Better Wi-Fi"
- Select "Scan Now"
Smart Home Manager will find the best channel. If you want to manually sign in to the modem to test channels on your own, we have instructions just for you:
- Update your radio
Helpful Hint: Each home is different so you may need to test a few channels.
Does your plan support all your devices?
We live in an age where everything is connected to the internet. If you have AT&T Fiber, you should not have any issues. If you have a low-tier plan like 100Mbps, 50Mbps, 25Mbps, or lower, depending on how many devices are connected can negatively impact your experience. In instances like this, you have 3 options:
- Optimize your settings & improve the modem environment
- Upgrade to a higher-tier plan
- Prioritize which devices should be online
With the Smart Home Manager, you'll find your internet plan and the number of devices connected. Also, our Speed Calculator can help you determine if you have the right plan or if you are using more than your plan can support.
Remember, each device shares a portion of your internet signal. If you have multiple users or devices on the internet at the same time, you may experience slow speeds, slow browsing, or downloading. Check out our Internet Plan & Number of Devices to learn more.
If electronics, like speakers or sound systems, are near the modem, the interference those devices emit can affect your speeds and slow down speeds. The links below go over how you can improve the modem environment and the best spot for the modem.
Heads Up: It is normal for wireless speeds to drop in half. Run a wired speed test with only 1 device connected. If your wired speeds test within your plan range, you'll need to improve the environment or optimize your settings. Learn why now.
