Network dropouts

[kdn]

Can anyone explain what these black dots mean for dhcp? Every time we have a user report a drop off we can coincide these with a "dhcp did not occur" in this case the user is sitting at the desk, not moving and it seems like a roaming across Ap's has occurred but the user experiences a loss of network for minutes at a time.

trying to understand what is causing this?

Have you tried to Enable/Disable "Inter-Station Traffic" setting... Go into your SSID, then click on Additional Settings  >>>Optional Settings >>> Customize and you will see a checkbox there for that Inter-Station Traffic.  Check or uncheck it, push it out (Not sure if you will have to do a full Push or a Delta, maybe try a delta to a single AP), and see if that goes away.  Let us know how it goes please.  Thanks,

any update?  I know with one of the firmware updates Extreme added some DHCP line - you will have to search community posts for that - which caused massive issues... maybe thats come back in the latest firmware update? - which im having issues with.

I’ve seen this before, those black dots show when a client doesn’t complete DHCP after roaming. The device jumps between APs but loses its IP for a bit. I’d check if all APs use the same VLAN and if the DHCP relay is set up consistently, that usually fixes it.
