Dear @ossidiana,

so , cattura ( the first i sent)  is data when i'm connected to the AP ( no stream internet) , cattura2 (this one i send you now)  is data when i'm connected to the main router ( that stream right internet.@Fae 

Upon the screenshots, to get the internet access from the router, the IP address should be 192.168.1.X with DNS server 192.168.1.1.

But when you are connected to the AP, the IP address is 192.168.0.x with DNS server 192.168.0.254, that's not from the router.

Did you set the CPE210 in Bridge mode and connect to the router's WiFi (TIM-26177953) after survey? 

Did you enable DHCP server on the CPE210's Network page?

It's suggested to check the configuration of CPE210, if necessary, refer to the guide below to reconfigure it.

How to Configure the Bridge Mode on the Pharos device, https://www.tp-link.com/support/faq/724/

Note:

*At Step 2 from the guide above, please change the LAN IP to fit in the main router’s network, for example, use 192.168.1.254.

*At Step 5, you can customize your wireless name (SSID) and password, and this is the difference between Bridge mode and Repeater mode.

If you still have trouble, please kindly provide the screenshots of the STATUS and NETWORK page on the CPE210.

Dear @ossidiana,

From the STATUS page, the Wireless Signal Quality and Root AP info display N/A, which means the CPE210 is failed to get a connection from the wireless network. Besides, the LAN IP address is the default 192.168.0.254, it seems that you didn't change it.

For the case, please check if the suggestions below help.

1. Upgrade the CPE210 V3 to the latest firmware <200612>.
