@Ethan-TP Thanks for the suggestions - I tried exactly these with no luck.
My Omada Controller does not allow me to capture packets from my ER707-M2 router. I went into the Tools and chose the "Packet Capture". When I try to select the Router as the source, it just says "This device does not support packet capture." I am sure, an ER707-M2 can capture packets.
Similarly I cannot use port forwarding...

My software Omada controller (attached to this router directly) version is 5.15.24.18.

Maybe is it the Essential Controller and not the Central Standard Controller?  How can I tell them apart?

How can I download the Central Standard Controller if this is the problem? I do not even heard about this edition of the Omada controllers...

Thanks in advance,

Gyula
 

  @Ethan-TP Thanks for the tip! I upgraded the all the firmware (router, switch, APs) - it was a surprisingly easy process, with no data loss 

For example the cable test just started to work with the switch in the Omada controller. It did not work earlier if I remember correctly (?)

But when I tried the packet capture it showed the same message: "The device does not support packet capture."

Please help me, what would be the problem?

Thanks in advance,

Gyula

  @Ethan-TP I followed the guide you referred to and was able to collect all the information I wanted. It is now clear that the problem not at the network level, as all network communication are working as expected.

Thank you for your help, I really appreciate it!
