@Marvin_S sorry i didnt know that and just sent mail as it shows on thread. Thank you so much. App version is 3.8.129. The network optimization i mean auto channel choose. In this way i have to go to network optimization to change channels but some other routers and mesh systems choosing channel automatically all the time. 

  @Marvin_S I dont wanna steal your time but i have one more question. I have a Zyxel DX3300-T1 Wi-Fi 6 VDSL2 modem provided by my ISP. I live in an apartment, and fiber optic internet comes to the building, but VDSL is used from the building’s distribution box to my apartment(FTTB). I can set the ISP modem to bridge mode, and they also share the PPPoE username and password with me. I live in Turkey, and my ISP is Türk Telekom.Which setup do you recommend me?

Network Setup Options:

1. Option 1:

• Modem: In standard mode, Wi-Fi enabled.

• Deco: In Access Point mode.

• The modem and Deco use the same SSID and password.

2. Option 2:

• Modem: In bridge mode, Wi-Fi disabled.

• Deco: In Router mode, with PPPoE connection.

3. Option 3:

• Modem: In standard mode, Wi-Fi disabled.

• Deco: In Router mode, with Dynamic IP configuration.

4. Option 4:

• Modem: In standard mode, Wi-Fi disabled.

• Deco: In Access Point mode.
