Hi  @TomMoerman 

The issue you described is a bit confusing. Please answer the following questions to help us understand the specific problem.

1. When the issue happened, all wireless clients couldn't see the SSID?

2. When the issue happened, if scan the SSID via a wifi scanner, will the SSIDs appear?

3. How many SSIDs did you configure in total? Did you enable both 2.4G and 5G for them?

4. When the issue happened, did all the SSIDs disappear?

5. How can you recover the issue? Do you need to reboot the EAP units, or will the SSIDs reappear after some time? if yes, around how long?

6. Apart from the two EAP610-outdoor, do you have other EAP units? If yes, are they broadcasting the same SSIDs?

In the meantime, you may have a look on the following article to identify if it's related:

Hi  @TomMoerman 

Thanks for your reply.

 No recovery possible

>>>What did you try? Did you try reboot the EAP? Please also try to factory reset the EAP.

Please use a pin/pen to press and hold it for around 8 seconds unitl you see the LED changes.

Hi  @TomMoerman 

After reset, will you see the default SSID for the EAP? Or do you mean there is still no SSID broadcast even under the default settings?

Hi  @TomMoerman 

After resetting the EAP units, did you adopt them to a controller? This will happen if no SSID is created on the controller.

No SSID is broadcasted.

If not, and the EAP won't broadcast wireless signal with defaut settings under standalone mode, it seems that it's defective, you may contact your retailer to check the warranty.
