Many users want to remove devices from AT&T Smart Home Manager because they see old phones, unknown devices, smart TVs, or duplicate Wi-Fi devices in the connected devices list.
Why Remove Devices from AT&T Smart Home Manager?
Steps to Remove Devices from Smart Home Manager
- Open the App: Launch the Smart Home Manager app on your smartphone or go to myhomenetwork.att.com.
- Log In: Sign in with your AT&T user ID and password.
- Go to Network: From the dashboard, select Network.
- View Devices: Tap Connected Devices to see a list of everything currently using your Wi-Fi.
- Select a Device: Choose the device you wish to remove or restrict.
- Block Access: Select “Block Access” to disconnect the device from your network.
Note: You cannot “delete” devices entirely—they reappear if they reconnect. Blocking them prevents unauthorized access.
Common Reasons to Remove Devices
- Suspicious or unknown device showing up
- A child’s device needs screen-time control
- Old gadgets no longer in use
- Improving bandwidth and speed for active devices
How to Identify Unfamiliar Devices
Each device has a unique MAC address. If you notice a strange name, check your home devices or use the MAC address filter in your router settings.
Refer to this guide on securing smart home networks to prevent unauthorized access.
Can You Permanently Remove a Device?
No, the system doesn’t allow permanent deletion. However, by using “Block Device” and managing passwords or enabling a guest network, you maintain tighter control.
What Happens When You Block a Device?
The blocked device cannot access the internet unless unblocked manually. It appears greyed out in the device list with a blocked symbol. This is useful for managing family schedules or unauthorized gadgets.
Helpful Tips
- Change your Wi-Fi password regularly for enhanced security.
- Enable two-factor authentication on your AT&T account.
- Set up device profiles to schedule access for family members.
Advanced Security Options
Use tools like AT&T Internet Security or third-party options such as Bitdefender Home Network Security to add an extra layer of protection.
Can You Remove a Device from AT&T Smart Home Manager?
Yes, but the wording can be confusing. AT&T Smart Home Manager mainly shows devices that are connected to your network or have recently connected. Depending on the device and your gateway, you may see options such as view details, rename, add to profile, pause, block, or manage device settings.
AT&T’s support page says Smart Home Manager lets you choose Network, then Connected Devices, and only devices connected to your network will show. It also says you can edit device details, add a device to a profile, block it from your network, or run a device security scan if enabled. AT&T support
So if you are looking for a “delete forever” button, you may not always find one. For security, the better solution is usually to block the device or change your Wi-Fi password.

Remove vs Block vs Pause: What Is the Difference?
| Action | What It Does | Best For |
|---|---|---|
| Remove | May remove a device from a profile or device list if available | Cleaning up old devices |
| Block | Stops the device from using your Wi-Fi network | Unknown or unwanted devices |
| Pause | Temporarily stops internet access for that device or profile | Kids’ devices, screen time, temporary control |
| Rename | Changes the display name of the device | Identifying unknown devices |
| Change Wi-Fi password | Kicks off devices that do not know the new password | Best security fix for unknown users |
Why You May Not See a Delete Button
If you cannot remove devices from AT&T Smart Home Manager directly, use the block option or change your Wi-Fi password to stop unwanted access. Many AT&T users search for “delete device from Smart Home Manager,” but the app may not show a direct delete button for every device. That is because Smart Home Manager is mainly a network management tool. It shows connected or previously connected devices based on your gateway’s detection.
If a device is currently connected, you usually manage it rather than delete it. If it is old or offline, it may disappear later, or it may remain in history for some time.
What to Do If an Unknown Device Appears
If you see an unknown device in AT&T Smart Home Manager, do not ignore it. Sometimes an unknown device is harmless, such as a smart TV, printer, tablet, gaming console, Wi-Fi extender, or phone with a private Wi-Fi address enabled. But it can also be an unwanted connection.
Do this:
- Check the device name, brand, and connection type.
- Compare it with devices in your home.
- Pause or block it temporarily.
- See if any of your devices stop working.
- If you still do not recognize it, change your Wi-Fi password.
AT&T says if Smart Home Manager cannot identify the device type, it may show the device as Other or Unknown. AT&T support
Best Way to Remove an Unwanted Wi-Fi Device
The strongest way to remove an unwanted Wi-Fi device is to change your Wi-Fi password. Blocking can stop a device, but changing the password makes sure only people with the new password can reconnect.
AT&T’s Smart Home Manager page says unwanted devices can be handled by blocking them or changing your password, but if you change the password, you must update the password on all connected devices. AT&T Smart Home Manager
How to Change Your AT&T Wi-Fi Password
Use these general steps:
- Open the AT&T Smart Home Manager app.
- Sign in to your account.
- Go to your Wi-Fi or network settings.
- Choose your Wi-Fi network name.
- Edit the Wi-Fi password.
- Save the changes.
- Reconnect your trusted phones, laptops, TVs, cameras, and smart home devices.
After changing your password, unknown devices should not reconnect unless someone has the new password.
Why Old Devices Still Show in Smart Home Manager
Old devices can stay visible for several reasons:
- The device has recently connected to your Wi-Fi.
- The gateway has not refreshed the list yet.
- The same device is using a private or randomized MAC address.
- The device name changed after an update.
- A smart home device reconnected in the background.
- The app is showing a cached device list.
If the old device is not connected and has no internet access, it may not be a security problem. But if it keeps returning as active, you should identify it or change your Wi-Fi password.
Private Wi-Fi Address Can Create Duplicate Devices
Many phones and tablets use private or randomized Wi-Fi addresses. This privacy feature can make the same phone appear as a new device in your router or Smart Home Manager.
For example, your iPhone may appear once under its normal name and later appear again as an unknown or new device. Android phones can do something similar. This does not always mean someone hacked your Wi-Fi.
If you see duplicate devices, check your family phones first before blocking everything.
How to Identify Unknown Devices in AT&T Smart Home Manager
Try these checks:
- Look at the device brand or manufacturer.
- Check whether it is connected by Wi-Fi or Ethernet.
- Turn off one device at a time and refresh Smart Home Manager.
- Check smart TVs, printers, tablets, cameras, thermostats, and gaming consoles.
- Rename devices once you identify them.
- Add family devices to profiles so they are easier to manage later.
Renaming devices is useful because many device names are unclear. A smart TV may appear as a manufacturer name instead of “Living Room TV.” A phone may appear as “Unknown” if privacy settings are enabled.
Should You Block Unknown Devices?
Yes, if you do not recognize the device after checking your home devices, you should block it or change your Wi-Fi password.
For a device that might belong to your family, pause it first. If someone complains that their phone, TV, laptop, or console stopped working, you can identify and rename it. If nobody notices, it may be safe to keep blocked.
How to Keep Unknown Devices Off Your AT&T Wi-Fi
- Use a strong Wi-Fi password.
- Do not share your main Wi-Fi password with everyone.
- Use the guest Wi-Fi for visitors if available.
- Rename devices after identifying them.
- Review connected devices regularly.
- Block devices you do not recognize.
- Change your password if unknown devices keep reconnecting.
Common Problems and Fixes
| Problem | Likely Reason | Best Fix |
|---|---|---|
| No delete button | AT&T may only allow block, pause, or edit | Block the device or change the Wi-Fi password |
| An unknown device appears | Device name not recognized | Pause it, identify it, then rename or block it. |
| The old device keeps showing | Cached or recently connected device | Refresh the app, restart the gateway, or wait |
| The same phone appears twice | Private Wi-Fi address or randomized MAC | Check phone Wi-Fi privacy settings |
| Blocked device reconnects | The password is still known, or the device changed its address | Change Wi-Fi password |
| Smart Home Manager not updating | App cache or gateway sync issue | Restart the app and the gateway |
When You Should Restart the Gateway
If Smart Home Manager shows outdated device information, restart your AT&T gateway. This can refresh the connection list and fix temporary app or gateway sync issues.
Restarting the gateway may briefly disconnect your internet, so do it when nobody is using important video calls, online work, gaming, or streaming.
Final Verdict
The safest way to remove devices from AT&T Smart Home Manager is to first identify the device, then block it or update your Wi-Fi password if it is unknown. To remove devices from AT&T Smart Home Manager, start by opening the app, going to Profiles & devices, and selecting the device you want to manage. If the app does not show a delete option, use Block, Pause, Rename, or remove the device from a profile.
If the device is unknown or keeps reconnecting, the safest fix is to change your Wi-Fi password. That removes access from devices that should not be on your network.

Why can’t I delete a device from Smart Home Manager?

Why does Smart Home Manager show unknown devices?
Smart Home Manager may show unknown devices when it cannot identify the device type or name. Phones with private Wi-Fi addresses, smart TVs, printers, Wi-Fi extenders, and smart home devices can sometimes appear as unknown.
Will changing my Wi-Fi password remove all devices?
Changing your Wi-Fi password will disconnect devices that do not know the new password. You will need to reconnect your trusted phones, laptops, TVs, cameras, and smart devices manually.
Can I remove old devices from AT&T Smart Home Manager?
