Try the following solutions:

• Check the LED indicator status of ONT:

If the PWR LED indicator is off, ensure that the ONT is powered on properly.

If the LOS LED indicator blinks, ensure that the PON port is clean and connected properly, the fiber cord is not bent excessively and the input optical power is within the normal range (Rx Power between -28 dBm to -8 dBm on the Status > PON page).

If the PON LED indicator blinks, the ONT is not registered. Contact your ISP or verify the parameters for registration are correct.

• Ensure that your ISP supports self-purchased PON device for internet access.
• If you set the ONT to the router mode:

Ensure that the ONT obtains a valid IP address and gateway on the Status > Device > WAN Configuration page. If not, the WAN connection is not set up successfully. Verify the parameters are correct.

Ensure that the wired device is connected to a LAN port of the ONT or downstream router (if any) properly and set to Obtain an IP address automatically and obtain DNS server address automatically.

Ensure that the wireless device is connected to the Wi-Fi network of the ONT or downstream router (if any).

• If you set the ONT to the bridge mode: ensure that the router or computer used for dial-up is connected and configured properly.

If the problem persists, consult your ISP.
