Phenomenon Description:

We have been alerted to an issue where some GPON ONUs or sticks are only able to negotiate at 1Gbps when connected to the 10Gbps SFP+ Combo port of our Archer BE800/BE900 devices, despite potentially having a 2Gbps service plan with their ISP.

 

User feedback can be found in these community threads:

We understand the importance of achieving the full potential of your network and are committed to providing a seamless experience. To assist you in resolving this issue, please follow these troubleshooting steps.

 

Troubleshooting Suggestions:

 

1. Check Compatibility

Please ensure that your GPON ONU device is compatible with 10G WAN ports. It's suggested to refer to the manufacturer's specifications for details.

 

*We have found that certain 2.5Gpbs GPON modules, such as ODI DFP-34X-2C2, HUAWEI MA5671A, and Nokia G-010SA, work well with our routers. If you're using one of these modules, you should be fine with the connectivity as well as potential speed. However, it's always best to check the specifications before purchasing.

 

2. Firmware Update

Make sure your BE800/BE900 router is running the latest firmware for optimal performance and compatibility. Visit our website for the latest updates and installation instructions.

 

3. Restart the GPON Module

To refresh the connection, carefully remove the GPON module from the SFP+ Combo port on your BE800/BE900 device. Then, gently insert it back, ensuring that it clicks into place securely to ensure a proper connection. This simple step can often resolve intermittent connectivity issues.

 

Workaround:

If the GPON ONU stick still negotiates at 1Gbps rather than the expected 2.5Gbps, we recommend exploring the solutions discussed in the GitHub forum. Additionally, we're offering beta firmware for the Archer BE800/BE900 V1 that allows you to modify the port settings.

Note: Please be sure you have read the Terms and Conditions for TP-Link Beta Firmware before proceeding.

 

After updating, please refer to the steps shared by community member d5aqoep in the following link. These instructions will guide you through modifying the port settings to potentially resolve the negotiation issue:
