I'm in Aus, and I still have moments I go "get f***ed".. however, I did spend way too long trying to fix this issue at launch. I can say my WTF moments are down considerably, par ofcourse the usual BF moments.
I reckon a few things here might help you out. Hope it helps:
Easy / Most useful:
1) Use a wired Ethernet connection
2) Check for CGNAT and opt out if needed. If your ISP uses CGNAT, online gaming can suffer.
Contact your ISP and request: "GNAT opt-out" or a "static/public IPv4".
If your ISP offers a static IP or CGNAT removal option, do that BEFORE chasing dozens of smaller tweaks.
I reckon this is what fixed my connection packet loss outright.
3) Switch from an automatic DNS to known DNS provider, ie.
1.1.1.1
1.0.0.1
Medium Difficulty — router tweaks
1) Make sure UPnP is ON
2) Remove conflicting manual port forwards
3) Turn Flow Control OFF on the router
If your router exposes Flow Control RX/TX settings:
Turn RX OFF
Turn TX OFF
4) Set router Internet/WAN negotiation speed to Auto
If your router has an Internet Port Negotiation Speed option:
set it to Auto
5) Verify MTU
Check your MTU, especially if you are on PPPoE-based internet.
Bad MTU can cause:
fragmentation
packet issues
odd disconnects
inconsistent game traffic behaviour
6) Reboot and test
