Was told to open new thread for me issue so here it is.
I only have the problem in GTA V. I get disconnected from my friends party (or he from mine) after anywhere from 30 seconds to 3 minutes.
It started to do this on the 22nd November and as of now I am still getting problems. No point on contacting Rockstar as they just DON'T CARE about the players so I am just hoping someone will read this and have a solution for me.
I have deleted the system cache and my profile from the console, I have connected to network via network cable and wirelessly, nothing else on my network goes down at the same time.
