The help does not allow me to play online and it disconnects me too much. I do not know...

I checked my internet and everything is fine. Look at the Xbox services to see if there is a problem with the servers and it shows me that everything is fine. I just checked my Internet on my Xbox and everything is fine. This is shown, W: 0000-000B, X:

Hello Joahan,

Are you wired or wireless? With the console connected to the internet and you run test Xbox live connection, try this test a few times in a row. Reason being is if there is something going on, this might help determine the issue with the constant disconnect.
You may also want to call your internet service provider and ask them to run a diagnostic test on your line, to see if there are any issues through the line.

Thanks,

Brad
