Hi, Nice to see you again.

On the network map, there are other models apart from Deco X50. Could you please help me mark out the model number?

And how about their connections to other Deco units, WiFi, or Ethernet cables?

As for the speed issue you mentioned here, can I have more details? Which unit has a half-speed? How much speed is it supposed to get?

Wait for your reply and best regards.
