What can I do if my Decos have a wireless connectivity issue? (Case 3)

Note: If Deco’s LEDs are normal, it means that Decos are working fine. Why the clients have connectivity issues when all the Decos’ LEDs are normal? The related reasons for this symptom are special clients, wireless environment, or internal factors. Here are three situations that can locate your issue. (The more details you can provide, the faster we can locate your issue.)

Situation 1:Drop Internet only on wireless clients: (If only one device experience this issue, please tell us the model number directly. If two or more clients experience this issue, please try the following steps.)

  • Check the model number of your dropping devices. If they are windows computers, please try to update the driver of your Windows computers.
  • If the issue still happen, please help us check more detailed information:

         A.Wi-Fi is connected but no internet

  1. Do not reboot any Deco units then try moving the device near one of the Deco units and reconnecting Wi-Fi (turn Wi-Fi on and on), see if the internet could be back.
  2. Please try to enable 5G only guest network

Guidance:

>Open the Deco app, go to Wi-Fi settings, enable the guest network, uncheck the 2.4 GHz guest network, and only leaving 5 GHz (please remember, 5 GHz only). We will use this newly created network for your cellphones/laptops/mostly used devices.

>Rename your guest network (newly created network)

>Connect your cellphones/laptops to the newly created network, you may imagine this newly created network as a network that only serves your most-used devices.

The main wireless network and guest wireless network have two different names, in this way, your phones/laptops, mostly used devices will always be connected to the 5Ghz, which would be much faster and stable.

For example:

Main network: The current name.

Guest network: The current name _new.

Please note: The guest network and host network would be isolated in Router mode. (You may change it into AP mode if you have another router in your house)

  B.Cannot connect to the Wi-Fi

  Disable fast roaming and beamforming. (Open Deco APP and then go to More­--Advanced)

  Create a guest network without encryption.

If the steps listed here do not resolve your issue, please help us collect:

  1. The results of the above troubleshooting steps
  2. TP-Link account ID
  3. The model number of dropping devices and dropping frequency

 

Situation 2:Drop internet on wired clients and wireless clients
