"Experiencing intermittent slowdowns while running Win 10 ARM on M1 MacBook Air. Occasionally, when accessing a website idle office tycoon APK, upload speeds in the VM become sluggish while download speeds remain unaffected. Speedtest shows 80 Mbps down but only ~0.15 Mbps up. However, there are no issues when using the Mac directly, which achieves 80/80 Mbps speeds. This occurs on a shared network. Unsure if it's a Windows 10 or Parallels NIC driver problem. Temporary fix involves disabling and re-enabling the NIC in Windows. Haven't confirmed if it affects both LAN and WAN, but likely. Events in the viewer suggest potential Netbios-related errors. Considering disabling Netbios, but seeking further insights or solutions."
