Hi,@VolkerS 

Thank you for posting on our business forum.

To confirm, are you experiencing that the previously established Mesh connection disconnects after upgrading the firmware of your EAP610-Outdoor?

You mentioned in your post that "The EAP615 is recognized and adopted as a wired access point." We would like to confirm further: is your EAP615 actually physically connected to the upstream network via a wired cable?

Have you attempted to manually reconnect the EAP615 as a Mesh EAP to the EAP610-Outdoor after the firmware upgrade? If you still cannot add it successfully, is there any error message displayed during the process?

In addition, we would like to kindly collect more information for further analysis:

• What type of controller are you using, and what is its current version?
• What is the current firmware version of each of your EAP devices?
• What's the topology of your network?

This information will help us analyze your case more accurately. Thank you very much for your cooperation.

Hello,

The EAP615 can be adopted as an access point in the OC 300. It can no longer be used as a mesh repeater.

The EAP 615 is broadcasting an SSID, but I cannot connect in standalone mode because no IP address is being assigned.

There are no error messages because I can't even access the system.

In addition, we would like to kindly collect more information for further analysis:

• What type of controller are you using, and what is its current version?
• 
• What is the current firmware version of each of your EAP devices?
• 
• What's the topology of your network?

The EAP615 can be integrated as an access point.

The EAP615 cannot be configured in standalone mode because I cannot assign a password.

I can't see which setting I've overlooked.

The EAP615 cannot therefore be managed manually.

I bought and tested two new EAP615Wall devices today. As a result, the EAP615Wall devices can be ruled out as the source of the problem, since they shipped with an older firmware version.

These also failed to integrate into the system as mesh repeaters.

That leaves only the EAP 610 outdoor device with its firmware update.
