Deco M5 / slow network / DHCP
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
We have inherited 5 Deco M5's at a customer site - they are in AP mode, all connected via LAN cable to a Dlink switch. Hardware version mixed v2/v3
Internet access is via an Archer VR2800 router connected to same.
We've been having all sorts of issues with the network, high latency, unresponsive devices etc, for the last week or longer.
This has been isolated to the Decos since - when these were disconnected today - the network recovered and has been stable since.
There are no errors in any of the logs on the switch or router.
I've been over the Deco settings a dozen times. I can't see any obvious issue.
I know Dlink switches are supposed to be a problem, but DLink issued a beta firmware update to fix the IEEE1905 issue which at least allowed them to be detected when on cabled connection.
I thought that was job done (!) but my suspicion is that either the firmware update maybe didn't work or it's thrown up another problem.
Normally I'd replace the switch to test but it's a 24 port PoE (needed for the phones....) so expensive if it doesn't work
Any suggestions ? DHCP appears to be turned off on the Decos (and my understanding is that it doesn't activate in AP mode anyway)
