Problem
Packet loss is not always “bad Wi‑Fi”
Loss can be driver bugs, USB3 interference, saturated uplink, or local CPU failing to service the NIC fast enough. VantarisPro pairs network diagnostics with process and system context.
Why ping looks fine but voice drops
VoIP and games need low jitter, not just average ping. Bufferbloat, roaming, and DNS latency add variance. Local CPU spikes also delay NIC processing—misdiagnosed as radio issues.

Questions about this topic
Should I switch channels?
RF planning is step one—still correlate with local CPU and driver health.
Do USB docks affect Wi‑Fi?
Yes—USB3 noise can desense 2.4 GHz radios; test with distance or cable shielding.
Is Ethernet mandatory for gaming?
Often recommended—use diagnostics to prove whether Wi‑Fi is the limiter.
Can VPNs add loss?
Yes—note VPN state when comparing traces.
