@Vincent-TP 

Thanks for checking this out.

According to the Omada console, there is no any firmware upgrades available for both EAPs. Here is a screenshot of the firmware versions I have.

By the way, I was able to see the topology correctly up until a week ago without any issue under same software and firmware versions. I have tried restarting all the devices including the controller, but still I'm seeing above incorrect topology.

I have connected both EAPs via a TL-SG1008P, 8 Port Gigabit PoE Unmanaged Switch as follows.

ER605 ---> TL-SG1008P ---> EAP655 ---> ~10 wireless clients

                                        |---> Controller

                                        |---> Wired client (non PoE)

                                        |--->EAP615 ---> 1 wired client (non PoE)

                                                             |---> ~ 5 wireless clients

Thanks,

Charitha

Hi  @Vincent-TP 

I tried steps you have mentioned above. But none of them solve the issue.

I have restared all the devices in the network including the switch. Further I tried force provisioning all the managed devices in the network. But non of them worked even I have tried to view the topology with a private window, and a different browser along with each steps.

Thanks,

Charitha

Try and restart controller..

@MR.S 

Already restarted all the device including the controller. But results are still the same. Not showing any of EAPs or wireless devices connected via EAPs.

Thanks,

Thank all for the advise. 

I was very frustrated. But I did reset my OC200 controller and cleared the cache & Cookies and it worked flawlessly. Thank you all.
