tp-link Deco XE75 Whole Home Mesh Wi-Fi 6E System

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. If you’re not sure, please launch the Deco app, go to the Network/More->Wi-Fi Settings page to check your wireless password and Wi-Fi name.
2. Refer to the link to check whether the device is on the blacklist. If yes, remove it from the blacklist.
3. Turn off the Fast Roaming feature. Some devices may not be compatible with Fast Roaming thus fail to connect to the Wi-Fi network. In this case, it’s suggested to launch the Deco app and tap More -> Advanced. Find and turn off the Fast Roaming feature.
4. Turn off the 5G Wi-Fi network temporarily. Some smart devices only support 2.4G Wi-Fi and need to be configured with a phone, and they require the phone to be on the same Wi-Fi band during configuration. In this case, turn off the 5G Wi-Fi network temporarily when setting up the smart device will solve the Wi-Fi connection issue. You can launch the Deco app, tap Network/More->Wi-Fi Settings page, and then turn off the 5G Wi-Fi network.
5. Connect your device to the guest network for a try.
6. Change the wireless security type on the Deco app. On the Deco app, you can tap Network/More>Wi-Fi Settings>tap Security to change the wireless security type.
7. Ensure there are no special characters in the SSID and wireless password, such as apostrophes.

This Article Applies to:

If Deco units were working before but stopped working suddenly or the Deco network has an unstable issue, please refer to the corresponding suggestions to troubleshoot. Before troubleshooting, please ensure the Deco units are using the latest firmware version. If not, click here to update.
Case 1. Main Deco drops out or lost internet suddenly.

Check if the modem is still working when the problem happens

Disconnect the main Deco from the modem, and then connect a computer to the same Ethernet port on the modem with the same Ethernet cable. After that, check if the internet is available on the computer.
If the computer has no internet access when connected to your modem directly, please contact your ISP or modem support.

Check the LED status on the main Deco.

If the main Deco has a red LED(please record if it is solid red or flashing red), unplug the Ethernet cable between the modem and main Deco, and then connect them again after 10 seconds, then please check if the issue can be resolved automatically.
If unplugging and plugging the Ethernet cable doesn’t help, please try to reboot the main Deco and see if the internet will be back automatically(wait for about 3-5 minutes).
If still no luck, go to Deco APP -> More -> Internet Connection -> IPv4 to check the WAN IP address of the Deco. If there is an IP address, but Deco has no internet access, refer to the link to change the DNS server to 8.8.8.8 and 8.8.4.4 for a try.

Satellite Deco drops out or lost internet suddenly

1. Confirm LED Status when the issue happens on each Deco unit and confirm which Deco units are having the dropping issue
   Please distinguish solid red or flashing red, and record the MAC addresses of the Deco units, which have dropping issue.

2. Check whether there are any household appliances or metal products near it and the front Deco

The signal source and signal strength can be viewed in the Deco app.

A: If the signal strength displays Strong or Fair, there is no need to move Deco units.
However, if you have more than one satellite deco but only a specific satellite deco drops out, please try to swap the locations of the problematic deco and the working satellite Deco, and verify if the dropping issue happens on a specific location or specific Deco.
B: If the signal strength displays Weak, please try to move the satellite Deco closer to the main Deco, and place them at the same height if they are on the same floor.
C: If the satellite Deco is wired to another Deco, there is no need to move Deco units. Please check if there is a switch between the two Deco units. If yes, please try to remove the switch from the network and connect the Deco units directly. Then please check if the network is stable and record the model number of the switch.
