A specific client has no internet access when connected to Deco, while other clients work fine with the Deco network.

1. Check if the client obtains an IP address. If not, reboot or reset the client.

2. Check if the client has been configured a static IP address. If so, change the client to obtain the IP address automatically.

3. Update the driver of the client’s wireless adapter.

4. Check if the client is included in a profile under Parental Control, which is paused or in bedtime.

If the problem remains, it’s suggested to contact the support of the client.

If above suggestions can’t solve your problem, it’s suggested to contact TP-Link support
