Hi all,

I installed an RE315 a few months ago as a range extender to my Orbi Mesh (953). 

The RE315 uses a different SSID from my main network and  only 3 devices use the RE315 SSID.

What I've observed is that the extender sends 7-8 ARP requests every 1-2 seconds on my main network, asking for mac addresses of various devices that are not connected to it. I suspect this is a problem because my IoT devices (WiZ lights) have started behaving erratically (i.e. slow responses/unpredictable). My theory is they are spending too much of time responding to these ARP requests from the 315.

Questions:

a) Why is the extender doing so many ARP requests and that too to clients that are not connected to its SSID?

b) How do I reduce the flow?

FWIW, I tried multiple combinations: I tried to only extend the 5G backhaul of my mesh via the extender (all my IoT devices use 2.4GHz), enabled access control to only allow the 3 devices on the RE315 - nothing seems to stop the ARP requests to a wide range of IPs on my network.

Thanks
