Game server inconsistent/laggy

Hello so I load up Apex and I play trios match and my game is perfectly fine but once I hop into the ranked lobbies the internet becomes so inconsistent to the point I don’t even want to play anymore. Certain games are fine and I can actually play the game but MOST games I can’t even play because of how terrible the lag is. I have tested my internet connection plenty of times and every other game besides “Apex” is perfectly fine. I have a nighthawk router to boost my connection, which then has a e-cable that goes into my console. I’ve even tried changing my network plan for xfinity and got the 2Gbps plan and that still didn’t resolve the issue. I hope next update y’all really fix the server’s because this is ridiculous!
