Hi! I’d be happy to help you get your AT&T Cell Booster back online. To clarify, you mentioned that after rebooting your router and then bypassing it, the Cell Booster still isn’t connecting to the internet—is that right? Also, could you tell me what the status lights on the Cell Booster are showing—are there any blinking or solid lights (and what color)?

Meanwhile, here are some initial steps we can try to get this sorted:

1. Power cycle your Cell Booster
Unplug the power cord from the wall outlet or the booster itself, wait about 10 seconds, then plug it back in. Sometimes a fresh reboot helps it establish a new internet connection. It can take up to 30 minutes for it to stabilize after rebooting.

2. Check Ethernet connection
Ensure that the Ethernet cable is securely connected between the Cell Booster and the device it’s plugged into (since you bypassed the router, hopefully directly to the modem). Confirm the cable isn’t damaged and try swapping it with another cable if you have one on hand.

3. Confirm internet connectivity on the modem
Since you bypassed the router, the Cell Booster should connect directly to your modem. Can you confirm if the modem is providing internet to other devices when directly connected? This will help rule out any internet service issues.

4. Verify modem’s LAN port status
Some modems may have LAN ports disabled or require special settings when connecting devices directly. Check if the port you plugged the booster into is active and not restricted.

If after doing these, it still doesn’t connect, it would be helpful to know exactly what the Cell Booster’s LED lights are indicating, as that can give clues about what part of the connection is failing.

Let me know what you observe, and we can dig deeper from there!

Yes booster not connecting to internet. Booster power light blinking white, internet light blinding amber, o other lights are on. Have done unplug and reboot several times. connections from to booster working and modem providing service to other devices modem LAN port is active and not restricted.

Thanks for the detailed info—that blinking white power light along with the internet light blinking amber usually indicates the booster is having trouble establishing a full internet connection or activation1.

Since you’ve already power cycled multiple times and confirmed the modem and LAN port are working for other devices, here are some next steps to try:

1. Check for firmware updates
Sometimes the Cell Booster firmware needs updating to resolve activation/connectivity issues. The booster updates automatically via the internet, so without a connection it can get stuck. Since you can't connect now, a reset might nudge it to try again.

2. Perform a Factory Reset of the Cell Booster
To reset the booster:
- Locate the reset button (usually a small pinhole on the device).
- Use a paperclip or similar tool to press and hold the reset button for about 10 seconds until the power light changes (often blinking faster or turning off/on).
- Release the button and wait for the booster to reboot fully, which can take up to 30 minutes.
This resets all settings, so you might need to set it up again through the app after.

3. Verify your booster registration
Check in the AT&T Cell Booster app or your AT&T account that your booster is still registered and active. Sometimes after network changes or resets, the device may need reactivation.

4. Review router or modem settings once more
If you’re bypassing the router, ensure the modem isn’t providing a private IP or applying any firewall that might block the booster’s registration traffic.

If the reset and checking registration don’t resolve the issue, it could be worth contacting AT&T support directly for account-side checks or possible provisioning errors.

Would you like me to guide you through the factory reset process in more detail? Also, do you have access to the AT&T Cell Booster app to check status or registration there?

I just did a factory reset. will check registration and make sure setup is completed. I will have to check with Internet provider tomorrow to verify if the modem provides a private IP address, which I don't think they do.

Thanks for the update! Since you’ve done the factory reset and plan to check registration and modem IP details, that’s a great approach.

Regarding your question about setup issues with the AT&T Cell Booster app after a factory reset:

1. Download and Open the AT&T Cell Booster App
Make sure you have the latest version of the app installed on your phone or tablet (available from the App Store or Google Play). The app helps guide you step-by-step through registering and setting up the booster after a reset.

2. Follow the On-Screen Setup Instructions Carefully
After the reset, the app should detect your booster and guide you through reactivating it on your AT&T account. This involves connecting to the booster’s temporary Wi-Fi network the first time, then confirming device details and account info.

3. App Connectivity Issues
Sometimes the app may not detect the booster immediately if it hasn’t fully rebooted or established a network link yet. Try waiting a few minutes after reset, then refresh the app or restart it.

4. Troubleshooting Common App Setup Problems
- Make sure your mobile device running the app is connected to the same internet network or can access the booster’s temporary Wi-Fi.
- Disable any VPNs or firewall apps temporarily on your phone during setup, which might block the connection.
- If you get stuck, restarting both the booster and your phone’s app can help refresh the connection.

5. Review Booster Status Lights
Even after reset, check if the power light changes from blinking white to solid white and the internet light turns green, which means the booster is fully connected and activated.

6. If Setup Fails
If the booster won’t register or the app doesn’t list your device, it might be a provisioning issue on AT&T’s side or related to your internet provider’s network settings. In that case, contacting AT&T support for backend checks is recommended.

For more detailed setup instructions, the AT&T Cell Booster app and official AT&T support articles provide step-by-step guides for post-reset activation 1 10.

AT&T Cell Booster not working but modem is providing service to other devices

Hi! It sounds like your AT&T Cell Booster isn’t working even though your modem is delivering internet service to other devices. Let’s troubleshoot this step-by-step to get your booster connected again.

Since your modem is functioning properly, here’s what I recommend:

1. Power Cycle the Cell Booster
Unplug the power cord from the booster for at least 10 seconds, then plug it back in. This simple reboot can often clear temporary glitches and allow the booster to re-establish its internet connection1.

2. Check Ethernet Connection
Double-check the Ethernet cable between your modem and the booster. Make sure it’s firmly plugged in, not damaged, and ideally try swapping it with another cable to rule out cable issues.

3. Confirm Booster’s Status Lights
Note the color and behavior of the power and internet lights on your booster. For example, solid white power light with a green internet light usually indicates a good connection. Blinking amber or white could indicate connection or activation issues1.

4. Verify Modem Settings
Since other devices connect fine, ensure your modem is providing a public IP address and not assigning a private IP or firewall that could block the booster’s activation or connection. Sometimes ISP equipment or settings interfere with these devices.

5. Use the AT&T Cell Booster App
Open the app to check the booster’s registration and status. If it’s not registered or activated properly, the app will guide you through setup or troubleshooting steps10.

6. Factory Reset if Needed
If problems persist, performing a factory reset on the booster can clear any misconfigurations. You mentioned you’ve reset before, so keep this in mind if other steps don’t help1.

7. Contact AT&T Support for Provisioning Help
Occasionally, the issue is on AT&T’s side with the booster provisioning or account registration, especially if the app can’t register the device. It can be worth contacting AT&T support for backend troubleshooting.

If you’d like, I can guide you step-by-step through any of these actions, or help interpret the booster’s light status to narrow down the issue. Just let me know! Are there any specific lights showing on your booster right now?

Cell booster not connecting to internet after router reboot. Have now bypassed router. No connect.

Hi! Since your AT&T Cell Booster isn’t connecting to the internet after rebooting your router and even after bypassing it, let’s go through some focused troubleshooting steps to get it back online.

1. Verify Ethernet Connection
Make sure the Ethernet cable is securely plugged into the WAN (internet) port of your Cell Booster and directly into your modem or router. Since you bypassed the router, the cable should connect from the booster directly to the modem’s active LAN port. Try swapping the Ethernet cable with a known good one just in case1.

2. Power Cycle the Booster and Modem
Even though you’ve rebooted before, try a power cycle sequence: first unplug power from the modem, wait 30 seconds; then power off the Cell Booster, wait 10 seconds; next power on the modem fully, then after it’s online power on the Cell Booster. Sometimes this helps the booster re-establish its connection6.

3. Confirm Booster Status Lights
Check the LED lights on the Cell Booster. Typically:
- Power light solid white indicates it’s on and stable
- Internet light solid green means connected to the internet
- Blinking amber or white signals connection or activation issues
If your internet light is blinking amber or another color, the booster isn’t connecting properly and may need a reset or configuration1.

4. Factory Reset if Needed
If the above steps don’t help, perform a factory reset on the booster by pressing the reset button (usually a pinhole) for about 10 seconds until the power light blinks. Then set it up again using the AT&T Cell Booster app or web interface. This clears any misconfigurations that happened after reboot4.

5. Check Network Settings and Firewall
Some modems or gateways apply firewall rules or restrict ports that can interfere with the booster’s connection to AT&T servers. If you have access, ensure the modem/router is not blocking traffic or using a private IP scheme that could cause conflicts5.

6. Use the AT&T Cell Booster App for Setup and Status
Open the AT&T Cell Booster app on your smartphone to check the booster’s registration status or any error messages. The app can guide you through reactivating or troubleshooting connection issues if needed10.

If after trying these steps it still doesn’t connect, there may be a provisioning or network issue on AT&T’s side or with your internet provider. In that case, contacting AT&T support directly for further assistance with your account and booster activation would be the best next step.

Please let me know what the current status lights on your booster are and if you’ve tried the factory reset already. I’m here to help you get this resolved!
