Hello, I just received my Flint 4 and I'm trying to configure it with my Huawei MA5671A ONU, which was working correctly with my previous router. I'm experiencing an issue with the SFP+ port on the Flint 4: - **Huawei MA5671A →** connected to the 10G WAN port via a media converter: everything works correctly, and I can get around 1.5 Gbps over Wi-Fi (after setting uci set network.wan.vendorid=xxxxx) - **Huawei MA5671A →** connected to the Flint 4 SFP+ port directly: the connection works after setting uci set network.secondwan.vendorid-xxxxx Is there a specific configuration needed for the SFP+ port to make the MA5671A negotiate at 2.5 Gbps? Thank you! ---

Hi, Thank you for the detailed information. From the current results, the MA5671A can establish the connection successfully through the Flint 4 SFP+ port, but the SFP+ link is currently running at only 1 Gbps. Could you please collect the following logs to help us investigate this issue? 1. Please remove the MA5671A,wait one minute, then run: ```auto dmesg -c > /dev/null ``` 1. Then insert the MA5671A, wait about one minute, export the output of: ```auto dmesg ``` 1. After the one-minute wait, also run and share the output of: ```auto swconfig dev switch0 show ``` Please also export the Router Log and send the logs to us via private message. > **How to export logs:** > > ![image](https://forum-static.gl-inet.com/original/3X/3/f/3f9dc5396be55054ea7ec1e98575a2d1bdf5ab98.png) > **How to send private messages:** > > ![image](https://forum-static.gl-inet.com/original/3X/e/8/e83457cd7af566bb0db86f5b13857fc4fbc4e843.png) Once we receive the information, we will investigate this further.
