I have done everything that xbox has told me to do to access xbox live. I repeatedly get the error code 80072ee2. I have opened all the required ports, and UPnP was enabled. And nothing. Contacted my isp and they said that the problem is on xbox's end. The internet works fine with all other devices. I hate that xbox refuses to take responsibility for the issue and continues to tell me it is my isp's fault. I really need a solution.
