ISP 1000 Mbps. Deco M5 wifi from Deco feature "Test Internet Speed" always <600 Mbps. Deco M5 Speedtest.net via Ethernet port around 800-900 Mbps.
Speedtest.net via Ethernet directly at modem always 800-900 Mbps. Set up as Access point. From Modem, each ethernet port goes directly to each Deco M5 via cat6 LAN cable.
LED on each Deco is stable green. In Deco app, each slave shows "<--> Ethernet".
Please suggest how to make it faster.
Appreciate every comment.
