PDA connect to newtwork and works fine, after PDA goes to sleep it wont connect anymore.

Can someone have any idea how to solve this?

Hi Goran,

What are the WLAN settings? Like wlan type, auth type, encryption type.

Try to enable proxy ARP and see if that helps.

@goran_stamenkovic Check if these devices has any recommended WLAN settings.

If everything is looking good, we have to take OTA (over the air) packet captures while reproducing the issue. Captures will tell us who is in fault and what can be done.

Check if changing default DTIM value helps or if device has a standard DTIM value recommendations.

In the capture I dont see any other traffic than ARP.

What I requested was OTA captures where we can see what traffic exchange is happening between AP-client while you reproduce the issue.

Hi Goran,

Refer the below KB article.

https://support.ruckuswireless.com/articles/000002607

Note: You have to select wifi1 for 5G radio captures and wifi0 for 2.4G radio captures, in wireshark.
