This constant issue with not connecting and Bungie putting it on our network settings is pure BULLYWACK. I had been playing for months with absolutely no issues, no not one.
Then one day in the middle of a mission the game shuts down and I haven't been able to connect since. All Bungie says is that it's a "Networking " issue on my part.
No, it's not PERIOD. I haven't changed one single setting on my Network and suddenly cannot connect and it's been a month.
I can load and access all other games except Destiny which incidentally is the only one I want to play but can't.
