@David-TP Hello. Problem solved. I set an IP address in the DHCP using Deco MAC ID and now, it works.

@Sunshine The Main Deco as internet IP. Deco Apps says: Adresse IP ok but no access to internet. And Deco led is RED That is strange because the computer I'm using to write this message is connected...

@Sunshine I already rebooted deco 10 times at least and IP adresse is ok as I can have access to internet through Deco Wifi. The problem is that Deco is still solid red and complain no internet...

When I came back to my home, I found all Deco XE75 with solid red led. It is usualy bacause deco doesn't have internet access but I'm usung my computer connecter to DEc wifi and I have internet...

@MikeBali Hello, did you get answer from Tp-link support? I have same problem. Thanks

@Harbifh Hello, exactly same problem with all my Apple devices using IOS17: internet doesn't work with the deco. Deco works well with other devices (android and Windows). Any idea ? thanks
