Network dropouts

kdn — Thu, 30 Oct 2025 04:39:29 GMT

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?

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.

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.

Yes its always happened when they have roamed to another AP (although user is not actually moving around)

But why I'm so suspicious of this is because its just one single SSID it happens on and its a small network just 10 AP's one flat subnet and the dhcp server is on the local router interface. So I cant imagine why we get these failures I also don't understand why we need dhcp every roam either if the lease is for 12 hours.

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,

Ok I can confirm its already checked, I think it makes sense to be enabled.

Network dropouts can be really frustrating. It’s worth checking for firmware updates, interference issues, and access point placement, as these are often the main causes. Reviewing logs around the time of the dropouts can also help identify what’s going wrong.

We never really got to the bottom of it, the inter-station traffic was enabled already which we needed to leave on since its a corporate network. Enabling 802.11ax seems to have made the best overall improvement (previously was on AC), I still see the drops but not as frequent and not as noticed by the users
