I would start by seeing if you are indeed getting packet loss on your connection by following the steps below and let me know the results of this test to see what is taking place with your connection. 1. Open a command prompt on a client PC, via the Start Menu search for "cmd". 2. Type "ping www.bungie.net -n 300". (This will ping the address 300 times. Substitute 220.127.116.11 with whatever address must be tested.) 3. Copy the results and paste them in your response to us.
