I dont know what is the hardware version, So i select V1. I have only one Deco m5 AC1300. I have 3 questions. Thanks for your valuebla answers.

Question 1: Are Deco & Tether the same applications with the same features ?

Question 2: Gigabit ports. 1 gigabit or 10 gigabit ? I use one of them for receiving the internet from the modem to deco. I use the other one to give internet from deco to my media server. Is it possible to get internet wireless to the deco and use 2 ethernet port to end internet from deco ?

Question 3: is it possible to limit speed of a device to internet ? I know how to give high priority but i want to set like 1Mbps for device 1, 10Mbps for device 2, 5 Mbps for device 3. I couldnt find an option for this. Please consider to add this feature for future update. Is is important for me.
