Blink Sync Module XR Unable to Connect to Xfinity 2.4 GHz Network After Power Outages

Dear Xfinity Technical Support,

I am requesting assistance with a persistent connectivity issue affecting a device on my home network following recent storm-related power outages in Marietta, GA.

Prior to the outages, my Blink Sync Module had been connected and functioning properly on my Xfinity network for approximately two years. After two power outages, the device no longer connects to my Wi-Fi network.

To troubleshoot, I have completed the following steps:

1. Reset the original device multiple times.

2. Power cycled the modem and router.

3. Replaced the Xfinity modem with a new unit.

4. Split the Wi-Fi bands to create separate 2.4 GHz and 5 GHz networks.

5. Attempted connection exclusively on the 2.4 GHz network.

6. Manually added the device MAC address to the router.

7. Attempted setup using multiple mobile devices.

8. Replaced the original device with a brand-new Sync Module XR and repeated the setup process.

Despite these steps, the device still fails to connect to the Xfinity 2.4 GHz network.

Below are the relevant details:

2.4 GHz Network Information

• SSID: 2.4 – DaHouse

• Frequency: 2.4 GHz

• Security Mode: WPA3-Personal Only

• Router MAC Address: [Edited: "Personal Information"]

Device Attempting to Connect

• Device Type: Blink Sync Module XR

• MAC Address: [Edited: "Personal Information"]

Mobile Device Used for Setup

• Samsung Galaxy S24 Ultra (Model SM-S928U)

Given that this issue began immediately after the power outages and persists even after replacing the modem, I would like assistance with the following:

• Confirming that WPA3-only security is not preventing device connection

• Checking for any modem firmware issues or required updates

• Verifying that no security/firewall settings (Advanced Security, xFi, port restrictions, etc.) are blocking the device

• Confirming there are no provisioning issues or network-level restrictions tied to my account

I have been troubleshooting this for two weeks without resolution and would appreciate direct assistance in determining whether it is a modem configuration or an ISP-level issue.

Please let me know if additional diagnostics or remote testing are available.

Thank you for your assistance.
