I have a TP-Link XZ000-G7 connected to my ANONET BB. The main issue is, it is showing Registered (O5), but the PPPoE is sending PADT and refusing to connect. What could be the problem? Is it the OLT blocking it, or the ONU is unsupported? Have configured VLAN in the ONU/Router, but still no result. INFACT, My XC220-G3v works flawlessly, despite it being TP-Link. Is there any new firmware from this year that I am not aware of, which will fix this issue? Or I should buy another ONU?
