Hi,

You can configure Deco M5 as access point and connect the 2 Deco units via wifi.  Modem--home router--Deco (AP mode) )))(((Deco (Repeater unit). 

The configuration steps are the same, while you need change the operation mode to Access point.

Note: Open Deco app, tab more-advanced-operation mode to change it. 

Then there may 2 networks, one from the home router, the other one from the Deco, while they are still on the same subnet cause the Deco works as an access point. Meanwhile, you can change the wifi name to the same. 

With Deco works as an access point, some advanced features do not work anymore, like parental control, antivirus,speedtest and so on. 

If you wanna use these features, configure Deco M5 as the main router is a good choice; and for the existing home router, you can connect it to the Deco by wifi or by cable to extend the wifi range as well. 

May it help and have a nice day. 

Hi,

You can change the wireless network name to the same under the 2 network scenarios.

Meanwhile, for the seamless roaming, it depends on whether your client devices support this function also.

May it help and have a nice day.

Kevin_Z, thank you for your advice. If i were to connect the Router (Archer) to the Deco by LAN cable (with the Deco as the main router), can i configure the Archer to be broadcasting the same wifi network as my Mesh so i don't have to "connect" to another network when i move along the house?

 

Second question. If i were to do Modem > Archer Router > Deco M5, by changing the wifi name, will i make the Deco network to be the "same" as the network broadcasted by the Acher router, asking for the same reason as I do not want to "connect" to another network when i move along the house. I like the "mesh" style where its all one continous wifi network.
