Routing issue between TPG and Blizzard/ game servers?

Level 1a


I was hoping to get some info on a puzzling issue I've had over the last few days: connection dropping off with the game servers (Blizzard Entertainment). In short, I disconnect with the Blizzard game launcher every 30 seconds or so.


After a loooooong and extensive testing/diagnostics process, both on my end and with their tech support team, I ran a WinMTR test, and Blizzard is adamant that the problem is due to a routing issue between my ISP and their servers (


And indeed, ** when I use a VPN on my machine, the connection to becomes stable ** (but because of the VPN, server ping is around 200ms when it used to be around 30ms)


I ruled out:

- software issues (uninstalled and deleted program data, then reinstalled

- router/port settings (stable connection via my phone network when using USB tethering)

- firewall settings (no recorded packet loss during the WinMTR test, in spite of 10+ disconnects)

- adapter settings / DNS settings (reset the adaptor, manually updated drivers, flushed DNS and restarted the computer a few dozen times for good measure)


I have a TPG NBN Hybrid Fibre Coaxial setup which otherwise works fine. I run Windows 10 Home, and use wireless internet (Killer 1535 Wireless Network Adapter).


Any ideas?
