4. Can Deco work without a modem?
Deco is an internet-sharing device and can’t provide the internet itself.
If you don’t have a modem but are able to access the internet directly through an Ethernet jack on the wall, then Deco can be wired to the Ethernet jack and then share the internet with the clients after the configuration is completed.
5. Can Deco work with existing home routers?
Yes, Deco can connect to your existing home router via an Ethernet cable to access the internet.
6. What are the advantages of Deco models supporting HomeShield?
HomeShield is a built-in service, available in all HomeShield routers and Deco Mesh products. It is a home networking protection kit that covers all security scenarios with its network security, parental controls, QoS, and comprehensive reports. For more details, please refer to: https://www.tp-link.com/homeshield/
7. Can I manage my Deco network remotely?
Yes, the Deco system can be managed remotely on the Deco App as long as the network is online.
8. Will Deco Wi-Fi Backhaul, Ethernet Backhaul, and PLC Backhaul work together?
PLC Backhaul and Wi-Fi Backhaul can work at the same time, while PLC Backhaul and Ethernet Backhaul can’t.
If there is no Ethernet cable between the Deco units, Wi-Fi Backhaul and PLC Backhaul will take effect at the same time.
If there is an Ethernet cable between the Deco units, then only the Ethernet Backhaul will take effect.
9. Can the Deco Mesh system work with fiber DSL cable or SIM card directly?
Currently, we don’t have Deco products with fiber ports to access the internet. But we do have VDSL Deco product working with DSL cable and 4/5G Deco working with SIM card.

9. Can I enjoy all features supported by the main Deco If different Deco models work together?
The following features require support from all satellite Decos for proper functionality within the Deco system, including Signal Source, IoT Network, 6G Band, and Wireless Access Control.
•IoT Network
If you enable the IoT Network on the main Deco, only the satellite Decos that support the IoT Network will enable and synchronize their IoT Network as well.
•6G Band
If you enable 6G Network on the main Deco, only the satellite Decos that support IoT Networks will enable and synchronize their 6G Network as well.
•Signal Source
If you enable Signal Source in your Deco system to select a preferred signal source for the satellite Deco and client devices, but a device is close to a satellite Deco that does not support Signal Source, the system will be unable to select the desired signal source for that device.
•Wi-Fi Access Control
If you enable Access Control in your Deco system and set up a whitelist on the main Deco, but one of the satellite Decos does not support whitelisting, it can result in situations where devices not on the whitelist can still connect to that particular satellite Deco.
10. Can multiple accounts manage a Deco network at the same time?
Currently, a Deco network can be controlled by an owner or by a manager account. Only one account can manage a Deco network at a time. If a new management account attempts to log in the other account will be kicked out. This is to ensure network stability and security.
11. How can I switch the main Deco without resetting the whole Deco system?
You can switch the main Deco with another satellite Deco. Here is the guidance: https://www.tp-link.com/support/faq/2400/

Yes, you can change them on the Deco App. Please open Deco App->go to More->Internet Connections->IPV4->Tap Internet Connection Type.
13. Can Deco PX50 build PLC Backhaul with Deco P9 and P7?
No. Deco PX50 uses the G.hn powerline standard while Deco P7/P9 uses the HomePlugAV powerline standard, which is not compatible with each other.
However, the Deco P9 and Deco P7 can build the Powerline Backhaul together.
14. Can the Deco system connect with the existing powerline network directly to access the internet?
We don’t recommend connecting Deco with the powerline network directly. For a better network, it’s recommended to use Deco PX50.

4. How much power consumption does each Deco take?
We can calculate the theoretical maximum power consumption based on the output voltage and current parameters of the power adapter. However, the actual power consumption should be lower than this value.
5. Can I use a DC extension to extend the cable length of the original power adapter?
Normally, we don't recommend using an extension cable due to some possible risks.
1. The quality of the extension cable is uncontrollable, if the contact resistance of the interface is too large, it will cause the interface to heat up and cause safety hazards.
2. The increase in cable loss will increase the output power of the power adapter, resulting in a decrease in the life of the power adapter. If the rated power of the power adapter is exceeded, safety hazards will occur.
If the customer insists on an extension cable, we can provide the parameters of the power cord. However, any problems caused by the extension connection will violate our warranty.
The parameter of the power interface (Male Size)
inner diameter: 2.1mm
outer diameter: 5.5mm
copper column length: 9.0mm
