Cannot connect to Deco Wi-Fi
454847 How to connect a device to my Deco?
Deco supports both wired and wireless connections.
For wireless devices, you only need to search Deco's Wi-Fi name on the client and connect with the Wi-Fi password.
Besides, each Deco provides two Ethernet ports on the back for wired devices such as PC, printers, TVs, etc. You can also connect a switch to the Ethernet port to expand the wired connections.
Note: Deco M3W does not have an Ethernet port.
What can I do if my wireless devices cannot connect to Deco?
If you fail to connect your device to the Deco, the below article will provide you with some suggestions.
On the Deco:
1. Confirm you are connecting to the correct Wi-Fi network and enter the correct password.

2. Refer to the link to check whether the device is on the blacklist. If yes, remove it from the blacklist.
