lag

My pc is good and my wifi is good but every time ive tried to play this game for the past 6 months if had 50 percent packet loss in and packet loss out is always 0. I stopped buying ea play for it because it just woudnt work. Recently steam was having a free trial of the game so i reistall it on steam linked to a diffrent ea account then before and its fine runs perfectly and i love the game. Then as my trial ran out i bought ea play on steam as i thought the problem was fixed and instantly the packet loss came back. So the file bf2042.exe has always extreme packet loss but bf2042Trial.exe is tottaly fine. Please help me i just want to play.
