As stated in my previous response, 'I have followed the connection troubleshooting with no relief. I play on Sydney Servers and my ping ranges from 9-14ms to 11-16ms when I log into game. Changing DNS did not assist either (I tried a variety of these)'
I have tried all popular DNS such as the google DNS you listed as well as local DNS, I have tried a variety of MTU settings including automatic also.
I still get packet loss every single game, it doesn't run smooth at all.
As mentioned in OP this started after an update early in Season 4.
I've been playing Apex since the end of Season 1 and never had any issues previously.
