Please, provide more detail information: When did the issue start happening? Sometime in April or early May Did you perform any network or configuration changes around that time? No What's the switchport configuration? Default settings: Port status Enabled Type Trunk Native VLAN 1 Allowed VLANs all Access policy Open Link negotiation Auto negotiate (1 Gbps) RSTP Enabled (Forwarding) Port schedule Unscheduled Port isolation Disabled Trusted DAI Disabled UDLD Alert only Tags none PoE Enabled Port mirroring Not mirroring traffic Are all client devices that having issue with the same model, OS, etc.? No, not all. We mostly use Dell Latittude laptops but have Dell desktops as well. Are there any recent Windows updates? No. Have you tested updating the Windows OS, drivers etc. to the latest? Manually disconnecting wireless on the machines that have both wired and wireless connected seems to resolve the issue. This goes for desktops as well. When PCs connected via Wired - when exactly disconnected - when it goes to standby / sleep mode etc.? This is intermittent. We can't think of anything else than the PC is sending traffic on both the wired and wireless interfaces. THe PC is not going in sleep mode. THe user is actively working on the computer and gets disconnected. Do you see any Event logs for the specific devices? Nothing out of the ordinary. Have you taken packet captures? Does the PC still have IP address? No, because it's intermittent and we can't reproduce it at will. When you configure the PC with a Static IP address - does it experience the issue? I haven't thought of that. The PC's obtain DHCP addresses. Ensure the Meraki switch is running the latest firmware Yes, neither the old nor the new firmware resolved the issue.
