Two things come to mind, both related to network address translation (NAT) not being configured properly in the router connecting you to the NBN.
1. Multiple computers/phones/t/tablets sharing the the same address without NAT will behave similarly. Turn everything off except one device and try that.
2. Buried deep in the tcp/ip setting is the maximum transmission unit (MTU) size that defines the transport layer block size. Normally with NAT this should be 1492 or less but if it’s larger the comms sort-of works but is slow and links often stall, as you describe, yet tests will pass.
Up to you to check that in Windows - and you may need to resort to the command line.
