Connection checklist
What to check first
Use the data center selector before entering ranked.
Packet loss matters more than a small ping difference.
Check EA Help if login or matchmaking fails globally.
Restart the game after changing region or network route.
Test one casual match before starting ranked.
Ranked stability
Good server choice rules
Do not choose a server only because it shows the lowest ping once. A stable 35 ms route with no packet loss is usually better than a 22 ms route with spikes.
For team games, the best route is often the lowest average ping across the whole party, not the best ping for one player.
