@David-TP Hey David Copper Field 😁 Today im facing an issue with WAN port when i connect my device to LAN port so the speed on WAN port goes to 100 Mbps from 1000 Mbps. I have seen my ethernet port speed on my ONT before that it was 1000 Mbps but now it's only 100 Mbps but why?? 🤔🤔 Don't forget to add option in Deco to auto detect WAN port speed because this feature is missing in Early Access it was available in Beta firmware and also some of my IoT devices took very long time to connect to Deco M4 after reboot or when power supply came back like Tuya Smart Plugs, Tuya Smart Bulbs, Huawei Solar Inverter and Midea AC even i tried Connection Preference and Turned OFF Mesh Technology on these devices but nothing changed still same issue.

Did the newly-connected LAN device have a 100 Mbps Ethernet port?

Does it make any difference if we enable the QOS and set the bandwidth to 1000 Mbps download/upload?

By the way, would a power restart of the ONT and main Deco help fix this issue temporarily?

Thank you very much.

Best regards.
