Step 2: Choose Your Method of Access
T-Mobile offers a couple of primary ways to view connected devices:
Sub-heading: Method A: Using the T-Life App (Recommended and Easiest!)
The T-Life app (formerly the T-Mobile Internet app) is your most convenient tool for managing your T-Mobile Home Internet. It's designed for ease of use and provides a comprehensive overview of your network.
Step 2A.1: Download and Log In to the T-Life App
Download the T-Life App: If you haven't already, download the T-Life app from your device's app store (Google Play Store for Android or Apple App Store for iOS).
Open the App and Log In: Launch the T-Life app. You'll need to sign in with your T-Mobile ID. If you don't have one, you'll need to create it. Business Internet customers generally do not sign in with a T-Mobile ID but may have a separate login process.
Navigate to Home Internet Management: From the T-Life Home screen, select Locate > Things > Manage. Alternatively, you might find a direct option like "Manage My Home Internet" on the home screen.
Step 2A.2: View Connected Devices within the App
QuickTip: Repetition reinforces learning.
Access My Wi-Fi Screen: Once you're in the Home Internet management section, look for a "My Wi-Fi" or "Network" screen.
View Device List: On this screen, you should see a list of devices currently connected to your gateway. The T-Life app is designed to clearly display:
Device names (if available)
Connection type (Wi-Fi or Ethernet)
Signal strength (for Wi-Fi devices)
Drill Down for Details: For more specific information about a particular device, tap on its entry in the list. This will often show you details like its IP address and MAC address.
Sub-heading: Method B: Accessing the Gateway's Web Interface (For More Advanced Users or Troubleshooting)
While the T-Life app is fantastic for most users, sometimes accessing the gateway's web interface directly through a browser offers a bit more granular control or is necessary for troubleshooting. This method is generally recommended if you encounter issues with the app or prefer a desktop interface.
Step 2B.1: Connect to Your T-Mobile Gateway's Network
Ensure Direct Connection: Make sure the device you're using (computer, laptop, tablet) is connected to your T-Mobile Gateway's Wi-Fi network or directly via an Ethernet cable. Disconnect any active VPN sessions as they can interfere with local network access.
Step 2B.2: Open a Web Browser and Enter the Gateway IP Address
Open Your Browser: Launch your preferred web browser (Chrome, Firefox, Edge, Safari, etc.).
Enter the IP Address: In the address bar, type the default IP address for your T-Mobile Gateway. The most common IP address is
http://192.168.12.1 Note: For some older models like the Askey LTE Wi-Fi Gateway (TM-RTL0102), the IP address might be
http://192.168.1.1
Press Enter: Hit the Enter key to navigate to the gateway's login page.
Step 2B.3: Log In to the Web Interface
Enter Credentials: You'll be prompted to enter a username and password.
Default Credentials: For many T-Mobile Gateways, the default username and password are located on a label on the underside or back of the gateway itself. Look for "Admin Username" and "Admin Password."
Changed Credentials: If you've previously changed these credentials and don't remember them, you might be able to reset them to default via the T-Life app or by performing a factory reset on the gateway (use with caution, as this will erase all your custom settings).
Click Log In: Once you've entered the credentials, click the "Log in" button.
Step 2B.4: Locate the Connected Devices List
The exact location of the connected devices list can vary slightly depending on your gateway model and firmware version. Look for sections or tabs labeled:
"Client List"
"Connected Devices"
"Network" (and then look for a sub-option like "Client List" or "Devices")
"Devices"
"Basic" or "Advanced Settings" (then look within for network or device management)
For example, on some models, you might need to select "Expert" then "Network" and then "Client List."
Within this section, you should see a detailed list of all devices connected to your gateway, including:
Device Name (if available)
MAC Address
IP Address
Connection Type (Wi-Fi or Ethernet)
Connection Status (Active/Inactive)
Step 3: Understanding the Connected Device Information
Once you have the list, take a moment to understand what you're seeing:
Tip: Look for examples to make points easier to grasp.
Device Names: Some devices will self-report a recognizable name (e.g., "iPhone," "Living Room TV," "MyLaptop"). Others might show generic names or just their MAC address.
MAC Address: This is a unique hardware identifier for each network-enabled device. It's often the most reliable way to identify a device, especially if its name is generic. You can usually find the MAC address of your devices in their network settings.
IP Address: This is the numerical label assigned to each device on your network. It's how devices communicate with each other and the internet.
Connection Type: Differentiates between devices connected wirelessly (Wi-Fi) and those plugged directly into the gateway (Ethernet).
Step 4: Identifying Unknown or Unauthorized Devices

This is where the real detective work begins! Go through the list of connected devices and cross-reference them with devices you own and expect to be on your network.
Make a List: It can be helpful to make a physical list of all your devices (phones, tablets, laptops, smart TVs, gaming consoles, smart home gadgets, etc.) and their approximate MAC addresses if possible.
Look for the Unfamiliar: Pay close attention to any device names or MAC addresses that you don't recognize.
Check Active Status: If a device is listed as "Active" but you know it shouldn't be, it's a red flag.
Consider Temporary Guests: Remember if any friends or family recently connected to your Wi-Fi.
Step 5: Taking Action on Unknown Devices (Crucial for Security!)
If you find an unknown or unauthorized device, it's time to act swiftly.
Sub-heading: Option A: Changing Your Wi-Fi Password (Strongly Recommended!)
This is the most effective way to remove unwanted guests from your network.
Access Wi-Fi Settings: In the T-Life app, go to "My Wi-Fi" or "Network settings." In the web interface, look for "Wi-Fi Settings" or "Wireless Settings."
Change Network Name (SSID) and Password:
Change the Wi-Fi Network Name (SSID): While optional, changing the SSID can make it harder for old connections to automatically rejoin.
Change the Wi-Fi Network Password (Key): This is the critical step. Create a strong, unique password that combines uppercase and lowercase letters, numbers, and symbols.
Save Changes: Apply the new settings.
Reconnect All Your Devices: Every legitimate device will be disconnected from your network. You'll need to reconnect them using the new Wi-Fi password. This ensures only trusted devices regain access.
Sub-heading: Option B: Temporarily Pausing Internet Access (Using T-Life App)
Some T-Mobile Gateway models, when managed through the T-Life app, offer the ability to pause internet access for specific devices. This is great for parental controls or temporarily disabling a device you suspect is causing issues.
Select the Device: In the T-Life app's connected device list, tap on the device you wish to manage.
Look for "Pause" or "Block" Options: You might see an option to "Pause Internet," "Limit Internet Time," or even "Block" the device.
Confirm Action: Follow the prompts to confirm the action.
Note: The "Block" feature might not be a permanent block in all cases and often works by preventing future connections with the current password. Changing the Wi-Fi password is a more definitive way to remove unwanted users.

Step 6: Regular Monitoring and Best Practices
Periodically Check: Make it a habit to check your connected devices list regularly, especially if you notice unusual network activity or slower speeds.
Keep Your App Updated: Ensure your T-Life app is always updated to the latest version to access the newest features and security enhancements.
Strong Passwords: Always use strong, unique passwords for your Wi-Fi network and gateway admin interface.
Consider a Guest Network: If your T-Mobile Gateway supports it (some do via the T-Life app), set up a separate guest Wi-Fi network for visitors. This keeps your main network more secure.
Firmware Updates: Ensure your gateway's firmware is up-to-date. T-Mobile usually handles this automatically, but it's good to be aware.
By following these steps, you'll have a clear understanding of what's happening on your T-Mobile Home Internet network, ensuring both security and optimal performance.
