Model: Deco M5  
Hardware Version: V3
Firmware Version: 1.6.5

After upgrading to 1.6.x I found out that there are some domain I cannot get in, e.g. pan.baidu.

I checked the Deco app, and ensure that firewall didn't blocked and no parental control had setup.

Hi, have you tried to change the WAN DNS to 8.8.8.8.8.8.4.4 to see whether it helped?

Please also try to add https://pan.baidu.com/ under the whitelist of Malicious Content Filter:

I tried to downgrade back to 1.6.1 but the problem still exist.

I changed the router for testing and it can connect to baidu com.

Quite sure that is the Deco M5 problem.

I recalled that at 1.5.x my Deco M5 can still connect to baidu com and pan.baidu com

Thanks for the update.

In this way, could you please send an email to support.forum@tp-link.com with the following information:

1. A picture of the IPV4 settings under Deco APP>More>Internet connection.

2. May I know who is your internet service provider?

3. Would there be any error message when you failed to access these websites?

Wait for your reply.

Best regards.
