Hi @SKL50 

Thanks for posting in our business forum.

You can refer to this:

What If My Windows Computer Is Not Accessible or Pingable Over the VPN/VLAN In

This is a more of a problem with your computer/device firewall settings. Not a router level issue if you have not configured any stateful ACL.

  @Clive_A Thank you for your answer, but it's not Windows related. I actually don't own a windows PC. 

I have the issue with synology, homematic, reolink hubs/gateways. All not pingable interestingly a wired Mac is pimegable from the other wireless network. 

This provides you a lane to think about the firewall if it is the reason for the problem.

I have not had a problem with the VLAN interface for years after it was added.

If you connect the computer A and B to the router directly and disable the firewall, do they ping?

I don't know what device or OS you have, nor how to disable their ICMP firewall if there is one. You need to refer to the OS manual. But the truth is, a VLAN interface by default without ACL config, allows pings.

A cellphone can be used to test as well to prove what I write. If you want a demo, I can get you a video.

It magically works now. I did not change any configuration, but I disconnected each device with a problem from the wired port (like hue bridge, reolink hub, etc.) and connected temporary a Apple Laptop. The Apple Laptop was accessible as expected. Afterwards I disconnected the Apple Laptop and plugged in the original device again. Suddenly no issues anymore. Device is accessible, as expected initially. Tbh this seems like a super weird bug.

 

ER7212PC is weak in performance as we added a feature in the previous firmware. It might be a sync issue where the config was not applied timely.

I must say it I'm astonished to read those explanations. It is not the first place where it is explained this way. Information that the hardware performance is weak is not mentioned anywhere on the product specs and looking at the number of devices it can theoretically support (2 switches and 10 EAPs) I would expect that the features available in the device work properly. But it seems that the device is not designed properly. I would have no problem with paying a bit more for it, still benefiting from its compact 3in1 build but avoid all the limitations caused by weak performance.

The product was not first released to the general public.

It was only sold to the partners who resell it to the retail store setup. Or a similar small setup where the performance is not hungry.

Since the product was released, the queries regarding the purchase of this model, at least from my replies, are not recommending it as it is not future-proof in my view.

Second, the product was not perfect, and it has clearly marked support for only 2 switches and 10 EAPs, which for the EAP was increased from the limited number to 10 as of now.

Third, the product was okay at its launch, but as the features grow with every firmware update, it performs worse than at its launch. That's also expected.

In my view, this stuff, except for a decent computer with Software Controller and hardware equivalent to ER8411, other models are not as powerful as my standard, and that's why I called it "weak" in this situation, which is also my perspective in explaining this to you. And it indeed cannot catch up with the update of the controller as a matter of fact. If you look at it in a different way, removing the controller from the ER7212PC would still make it a decent router (alone).

Not sure what you are astonished by. It is not the case that the thing is designed improperly. It is the controller that grows into bloatware(for this thing, it is bloatware. Too big and demanding for it.) as you asked for more features and the features require more CPU usage, RAM and space. And it cannot support both the controller and the routing well like its first firmware release.

There was no 8411 when ER7212 was released or other models like ER707-M2 or ER706W. Due to the performance issue, you have ER7212PC V2, which is equipped with better hardware.

Like a cellphone you use for years and with each update, you got bloatware, kernel update and more advanced features and it becomes laggy.

Edit:

Not to mention that the OC200 may be experiencing slowness under certain circumstances on config sync as it now hits its bottleneck. The delay in sync has been there since day 1 of the Omada. That's why it is called "Configuring" in status.
