@Dagoy Multiple things to keep in mind here: The latest firmware for M4 (V2) is 1.5.5. For V3 it's 1.5.1 afaik. You need to update the V2 model and V3 models separately via web ui. However, it looks...

@Papaey M4R is the name for all Deco M4 models. Check the bottom of your M4. It should say "Ver.: 2.0" or something like that. That's the hardware version.

@stellaren The firmware with "manual signal source selection" is in beta testing for M4 (V4), it'll be rolled out to other hardware versions of M4 in the future.

@PedroLourenco You need to wait for the next firmware where they support for manual signal source selection will be included

@Loco9 You also need to update the firmware... the latest version is 1.5.5 (20220823)

@Heymarcoh Deco E4 provides 100 Mbps only on Ethernet, not on Wi-Fi.
