Hi all,

I’m having a persistent and frustrating issue with my Deco M5 mesh.

Setup:

• 4× Deco M5 in AP mode

• Ethernet backhaul to a TP-Link MR600

• Separate SSID on the MR600 works perfectly

Problem:

Some clients randomly lose internet access while still showing excellent Wi-Fi signal.

Restarting the device, Decos, or router does not fix it. Connectivity returns later with no clear trigger.

Deco settings:

• Smart DHCP: disabled

• Fast Roaming: disabled

• Beamforming: disabled

• WPA2

• 2.4 GHz + 5 GHz enabled

Has anyone seen this or identified a root cause (band steering, ARP/DHCP issues, firmware bugs)?

Thanks,

Matt
