i can't connect to xbox live all the attempts what happens?

Tente reiniciar seu roteador e seu xbox, verificou se a qualidade da sua internet está boa? Pode ser algum problema relacionado.

[Mod Translated - Try restarting your router and Xbox, have you checked if your internet quality is good? It may be some related problem.]

In addition to
AquarrzSudnnym:

does it give any errors, is it wired or wireless?

if so check your modem, are there any error lights on it?

Check Support for unable to connect solution and

Power cycle your console and network hardware

To perform a power cycle reset, follow these steps:

1. Unplug the power cable from the back of the router, modem, or gateway for five minutes. If you have a router and a modem, unplug the power cable from both devices.
   
2. Restart your Xbox One console:
   1. Press and hold the Xbox button
      in the center of your Xbox One controller to open the Power Center.
   2. Select Restart console.
   3. Select Restart.
      Note If the console appears to be frozen, press and hold the
      Xbox button on the console for 10 seconds, until the console turns off. After the console shuts down, touch the
      Xbox button on the console again to restart.
      
3. After five minutes, plug the modem or gateway in first and wait for all the lights to return to their normal state.
   
4. If you are using a router, plug in the router and wait for all the lights to return to their normal state.
   

If it is an update issue you will certainly get an error code when trying to connect. Can you describe what happens when you try to go online?
