Pl 8% - 45%

Hello guys. I came here cuz i cant find solution for my packet loss. Im from croatia and playing on EU and CIS server and everything was great until last 2weeks. I had ping 40-60ms and PL was 0%. Then my PL go wild and jumping to 45% while ping was still 40-60ms. Changed to american server and my ping go 120-150ms and PL 1-10%.
Playing on wire not on wifi,having good pc and good stable internet. I tryed lot of solutions from internet but nothing worked. Other games are perfect and there is no problems with ping and PL. Saw post there gajin saying thier servers are working great and dont have problems.
Boys i need help😞
