Why do I receive packet loss(Apex Legends Ranked mode only)

When I play Apex Legends Ranked (only Ranked), I receive packet loss every few games or every game. I don't know what to do anymore. I have tried Ethernet and switching servers. It is not the first time I have had this issue. I had it 5 years ago; some repairmen came because the wires were bad and replaced them, and now the issue has come back. But now it is not the wire. I have talked to my internet provider, and everything they say is that there is nothing they can do, so now I'm here. I don't know what to do, and I can't have fun when I play this game anymore because of the packet loss. Please, anybody, help.
