GPON Terminal + HAP AC^2

Dear Friends,

I need your help with my network based on HAP AC^2 + GPON Huawei Echolife Hg8010.

I’m using an sfp via GPON terminal which connected to my HAP AC^2.
The Router itself shares net via Ethernet to TV, office, and kids room; via wireless with other devices (tablet, phones).
The problem is when I connecting GPON directly to the router I have all thee units connected in network and wireless are working too.
But when I do connection GPON to Router via ethernet socket plug (due to GPON is at entrance of my apartment and router is in another room) I’m loosing all my network wired and wireless having “No internet access” message at taskbar.

My specs are:

GPON Huawei Echolife Hg8010
HAP AC^2 on basic setting
Windows 10 x64
Winbox 6.42.7

I’m guessing your ethernet wiring between GPON Huawei and desired hAP ac location is faulty.

Test your line between the wall plugs.
