Ok I'll try to be as thorough as I can about discribing my problem.
For the most part my xbox live works great!
I can watch Netflix no problem all day.
Downloads are fast and smooth.
I can play games like World Of Warcraft on my PC all day with no interuptions.
I can play for hours online when I play solo but when I play with my brother (who lives across the street). We get 15-30mins of playtime before I get kicked out of party-> offline and my router needs to be restarted for anything that uses internet in my house to work again.
Nat Settings are OPEN
I have contacted microsoft and they have to clue.
I have replaced my router twice...
Tried on a different xbox same issues
any ideas? need more details just ask! Thanks for reading!
