high-ping

My ping used to be 110-120 ms for the last 3 months but yesterday I updated my windows 10 from 1806 to 1809 . Now, my ping on SEA server is 313+ and it won't come down at all, it reaches 500ms at times. The ping I get on EU servers is around 160-180ms. PS: I'm from Pakistan. I play PALADINS...
