Re: I am so, so, SO sick of EA's connection problems. CONSTANT disconnects.
With a game like NHL, rubber banding would make the game near impossible to play. If you have high latency, you'll probably see this happen. Once your connection gets too bad though, the disconnect will occur.
An FPS typically doesn't have an object like a puck that is continually in play. You shoot a gun and there's a beginning point and end point. It's a lot less complicated than a puck that is reacting to players, equipment and the environment. In order for it to be properly updated for both players, you're going to need a solid connection. It doesn't have to be fast. It just has to be stable and have a decent ping. My ping is normally around 40 ms and I'm not getting any lag. However, when I was on a wireless connection with about 15 feet between my system and the router, I regularly lagged and disconnected. That could have been due to multiple wireless devices in my home as well. Once I switched to a wire, all of that went away. I also switched to using my own router and modem instead of the combo unit my ISP provided. I researched it and found out they were known to have issues and not be good for gaming.
I understand the dangers associated with stretching a wire across a room. I've been doing this for years and there have been a few times it's been tripped on. Thankfully my pets ignore it. I can see how that might be an issue for some curious animals though.
If you do some research on wireless, I think you'll find a lot of information backing up how it's not a suitable connection for gaming. Hopefully, when 802.11 ax is more common, that won't be so much of an issue. I understand you're skeptical when every support person tells you wireless is the problem, but keep in mind, we troubleshoot these issues all day, every day. The overwhelming majority of those connection issue cases are from people on wireless. Hopefully, the Powerline helps. I know it has worked for some. I'd switch if I could trust them, but my wired connection is just too solid to give up.
The error message means you lost your connection to Xbox Live. You'll see that when you're trying to play digital content. It can't be verified you own it without being online. That also could mean there's an outage with Xbox Live though. It would be good to check their status page here if it repeatedly happens - https://beta.support.xbox.com/xbox-live-status.
