@pawanwazza ea explained why your connection can fluctuate in that thread I linked earlier it’s your isp traffic.
This is all taken from the help page about how your isp routes you below.
EAS FC uses game data centers so that someone else’s connection doesn’t impact your own gameplay. The game data center handles the distribution of gameplay information to all players.
The center collects inputs from your game at a set interval of time, and then sends this information back to everyone else in a match. This happens at the same time for all players and is determined by their individual connections.
For example, if one player is streaming 4K movies and trying to play on a weak Wi-Fi signal, their activities shouldn’t impact anyone else in that match. The game data center still sends the information back at the same time.
A game data center acts as the host of the match in multiplayer matches.
How does EA decide where to place game data centers?
We work with industry-leading enterprise technology partners for our game data centers and place them in high-population areas with quality technology vendors.
Our vendors provide us with robust technology that can process data from tens of millions of players. Adding more centers doesn’t automatically result in a better player experience. For that reason, we carefully analyze the long-term effects on the players in the surrounding region before implementing a new game data center.
Why do some players connect to a distant game data center?
EAS FC will always try to connect you to online matches on your best game data center. Although that’s often the nearest one, this isn’t always the case.
Internet service providers (ISP) generally don’t send data from Point A to Point B directly. They route this data across locations, sometimes across the globe. This can be a physical networking infrastructure limitation of some ISPs or part of their business model. These decisions are ultimately handled by ISPs based on their unique needs and situations.
In some cases, your connection to a game data center is the best connection available at the moment, even if it’s farther away. However, your connection can be routed elsewhere if internet issues impact the route that your network traffic would normally take, or if one of our game data centers is experiencing technical problems.
