To delete devices from Smart Home Manager, open the AT&T Smart Home Manager app, go to Profiles & devices, select the device, and use the available option to block, pause, rename, remove from a profile, or manage it. In many cases, AT&T does not show a direct delete button for every connected device.
Many users want to delete devices from Smart Home Manager because old phones, smart TVs, tablets, laptops, gaming consoles, or unknown Wi-Fi devices still appear in the connected devices list.
Many users want to delete devices from Smart Home Manager because old phones, smart TVs, tablets, laptops, gaming consoles, or unknown Wi-Fi devices still appear in the connected devices list.
The important thing to understand is this: Smart Home Manager mainly shows devices that are connected or recently connected to your AT&T network. If a device cannot be deleted directly, you can still block it, pause it, remove it from a profile, restart your gateway, or change your Wi-Fi password.
Quick Answer: If you cannot delete a device from Smart Home Manager, block the device or change your Wi-Fi password. This is the best way to stop unknown or unwanted devices from using your AT&T Wi-Fi.

Can You Delete Devices from Smart Home Manager?
AT&T’s official connected devices guide explains that Smart Home Manager lets users view connected devices, edit device details, add devices to profiles, block devices from the network, and run a device security scan if enabled.
Yes, but not always with a simple delete button. Depending on your AT&T gateway, app version, and device status, you may see options like block device, pause device, rename device, add device to profile, remove device from profile, or view device details.
- Block device
- Pause device
- Rename device
- Add device to profile
- Remove device from profile
- View device details
If the device is currently connected, Smart Home Manager may treat it as an active network device instead of something you can simply delete. That is why blocking or changing the Wi-Fi password is often more effective.
Delete or manage the device from the Smart Home Manager app.
Start with the Smart Home Manager app on your phone. This is the easiest place to delete devices from Smart Home Manager or manage connected devices.
- Open the AT&T Smart Home Manager app.
- Sign in to your AT&T account.
- Tap Profiles & devices.
- Open the connected devices list.
- Select the device you want to delete or manage.
- Check the available options.
- Use Block, Pause, Rename, or profile settings.
If you see a delete or remove option, use it. If you do not see one, continue with the fixes below.
Block the Device Instead of Deleting It
If your main goal is to stop the device from using your Wi-Fi, blocking is usually better than deleting. For a related guide, read how to remove devices from AT&T Smart Home Manager. When you block a device, it should no longer be able to connect to your AT&T home network.
Use a block when:
- You do not recognize the device.
- The device keeps reconnecting.
- You suspect someone has your Wi-Fi password.
- You want to stop internet access immediately.
Pause the Device Temporarily
Pause is different from a block. Pause is useful when you want to temporarily stop internet access without fully blocking the device.
Use pause for:
- Kids’ devices
- Gaming consoles
- Tablets
- Smart TVs
- Temporary screen-time control
If you are not sure whether a device belongs to your family, pause it first. If someone in your home says their phone, TV, or laptop stopped working, you can identify and rename the device.
Remove the Device from a Profile
If a trusted phone, laptop, TV, or smart device is blocked by mistake, you may need to add it back as an allowed device. See our guide on how to add exceptions to AT&T Smart Home Manager.
Sometimes users think they need to delete a device, but the device is actually attached to a profile. Removing it from the profile can clean up your device groups.
- Open Smart Home Manager.
- Go to Profiles & devices.
- Choose the profile.
- Find the device.
- Remove it from that profile if the option appears.
This may not remove the device from the entire network history, but it can clean up your family profiles and device groups.
Rename Unknown Devices Before Deleting or Blocking
Before you delete or block a device, try to identify it. Many devices show unclear names in Smart Home Manager.
An unknown device could be:
- Your iPhone is using a private Wi-Fi address
- An Android phone using a randomized MAC address
- A smart TV
- A printer
- A Wi-Fi camera
- A thermostat
- A gaming console
- A Wi-Fi extender
- A tablet or an old laptop
Once you identify the device, rename it clearly. For example, use names like Living Room TV, Office Printer, Kids Xbox, Front Door Camera, or Ali iPhone.
Restart Your AT&T Gateway
If old devices still appear in Smart Home Manager, restart your AT&T gateway. A gateway restart can refresh the connected devices list and clear temporary display issues.
- Unplug the AT&T gateway from power.
- Wait about 30 seconds.
- Plug it back in.
- Wait for the internet service to return.
- Open Smart Home Manager again.
- Check the connected devices list.
Do this when nobody is using important internet tasks like video calls, online work, streaming, or gaming.
Change Your Wi-Fi Password
AT&T’s Smart Home Manager page says the app can help users manage connected devices, schedule downtime, and block access to unknown devices.
The strongest way to delete unwanted devices from Smart Home Manager is to change your Wi-Fi password. This forces all devices to reconnect with the new password.
Change your Wi-Fi password if:
- You see unknown devices repeatedly.
- A blocked device keeps coming back.
- You shared your Wi-Fi password with too many people.
- You think a neighbor or visitor is still connected.
- You want a clean start for your home network.
After changing the password, reconnect only trusted devices.
Delete vs Block vs Pause: What Should You Use?
| Option | Purpose | Best Use |
|---|---|---|
| Delete | Removes device record if available | Old devices or cleanup |
| Block | Stops device from using Wi-Fi | Unknown or unwanted devices |
| Pause | Temporarily stops internet access | Screen time or temporary control |
| Rename | Changes device display name | Identifying your devices |
| Change password | Removes access from devices without the new password | Best security fix |
Why Deleted Devices Come Back
A device may come back in Smart Home Manager if it reconnects to your Wi-Fi, still has your Wi-Fi password, uses a private Wi-Fi address, or appears again because of cached gateway history.
- It reconnects to your Wi-Fi.
- It still has your Wi-Fi password.
- It uses a private or randomized MAC address.
- Your gateway still remembers recent device history.
- The Smart Home Manager app is showing cached information.
- The device is part of a profile or group.
If the same unwanted device keeps returning, changing your Wi-Fi password is the best fix.
Why Smart Home Manager Shows Duplicate Devices
Duplicate devices often happen because modern phones use privacy features that change the Wi-Fi address seen by routers. For example, one iPhone may appear as two different devices if a private Wi-Fi address is enabled. Android phones can also use randomized MAC addresses.
Before blocking a duplicate device, check whether it belongs to one of your own phones or tablets.
What to Do If You See an Unknown Device
- Check the device name and manufacturer.
- Check if it is connected by Wi-Fi or Ethernet.
- Pause the device temporarily.
- Ask family members if anything stopped working.
- Rename it if you identify it.
- Block it if nobody recognizes it.
- Change your Wi-Fi password if it keeps returning.
Do not ignore unknown devices, especially if they are actively using your network.

To delete devices from Smart Home Manager, start in the AT&T Smart Home Manager app under Profiles & devices. If a delete option is not available, use block, pause, rename, remove from profile, restart the gateway, or change your Wi-Fi password.
The best security fix is not simply deleting an old device name. The best fix is making sure unwanted devices cannot connect again.
FAQs
How do I delete devices from Smart Home Manager?
Open the AT&T Smart Home Manager app, go to Profiles & devices, select the device, and use the available options to delete, block, pause, rename, or manage the device.
Why can’t I delete a device from Smart Home Manager?
You may not see a delete button because Smart Home Manager shows devices detected by your AT&T gateway. Some devices can only be blocked, paused, renamed, or removed from a profile.
How do I remove an unknown device from AT&T Wi-Fi?
The best way is to block the unknown device in Smart Home Manager or change your Wi-Fi password so the device cannot reconnect.
Why do old devices still show in Smart Home Manager?
Old devices may still show because they recently connected, the app is showing cached information, or your gateway has not refreshed the device list yet.
Will changing my Wi-Fi password delete all devices?
Changing your Wi-Fi password will disconnect devices that do not know the new password. You will need to reconnect trusted devices manually.
Is blocking the same as deleting a device?
No. Deleting usually removes a device record if available, while blocking stops the device from using your Wi-Fi network.
Why does my phone appear twice in Smart Home Manager?
Your phone may appear twice because of a private Wi-Fi address or randomized MAC address settings. This can make the same phone look like a new device.
