Model: ER8411  
Hardware Version: V1
Firmware Version: 1.3.6 Build 20251028 Rel. 12399

ER8411 doesn't recover from the lost internet connection automatically. I had to click on the connect button from the controller UI. It doesn't even allow me to connect from the tplink omada cloud. I had to do it when I'm connected to the local network.

 

Connection attempt fail

 

 Here are the logs. The connection attempt fails until I click on the button. It connects immediately when I click on the button.

Hi  @Sathiya 

Thanks for posting in our business forum.

May I ask is this SFP WAN/LAN3 port the only WAN connection port on your ER8411? Is the connection button referred to the WAN configuration port on Internet settings? Can you descrbe your network topology as well?

Based on your situation, we suggest that you can try to connect the computer to the modem directly or try to replace the ER8411 with a different available router if possible.

Thank you for the response.

No, I have a WAN port which works fine.

 

Is the connection button referred to the WAN configuration port on Internet settings?

The connect button is in the device overview (right sidebar) > Ports tab > WAN tab. Please see the screenshot.

 

 

Can you descrbe your network topology as well?

ER8411 x 1

HSGQ-XPON-Stick x 2 (in WAN and WAN3 for connecting to ISP)

SX3206HPP x 1

EAP615-Wall x 1

 

Based on your situation, we suggest that you can try to connect the computer to the modem directly or try to replace the ER8411 with a different available router if possible.

Whenever I try to connect the computer, it always connects successfully. I just need to click the "connect" button manually, and it connects immediately. Unfortunately, I don’t have any other compatible router to test.

Hi  @Sathiya 

Thanks for your valuable reply.

Since your WAN port works fine without such connection issue, may I know the Internet connection type of this port and the ISPs of these 2 ports (WAN&WAN/LAN3)?

Or you may try to setup the PPPoE connection with another SFP WAN port to prevent physical hardware issue if possible.

  @Hank21 Thank you for the swift reply.

The WAN port uses GPON, while the WAN/LAN3 port uses EPON. One thing to note is that the ISP in the WAN port is stable and rarely disconnects. I never faced similar issues on the WAN port. Either it is not occurring, or I'm unaware.

 

Or you may try to setup the PPPoE connection with another SFP WAN port to prevent physical hardware issue if possible.

That's a great idea, but it requires considerable effort and is not immediately feasible.
