Same thing happens to me. I deleted my profile, re-downloaded and it didn't fix a thing. I play in the same house as my boyfriend right next to him hard wired to the same exact router and I'm the only one that gets kicked off. Can't even play for 20 minutes. Same thing with the party too, I went to a different game, my friend was in my party and loaded destiny, signed in and i got kicked offline. SO -blam!-ING ANNOYING.
