Internet Service Providers (Comcast, Spectrum, AT&T, Verizon) actively throttle heavy bandwidth users during peak hours. Here is the verified technical guide to eliminate bandwidth pacing permanently.
Broadband providers use Deep Packet Inspection (DPI) to look at the headers of your internet packets. When they detect BitTorrent swarms (Port 6881) or continuous 4K video streams (YouTube, Netflix), they artificially inject TCP bufferbloat to slow down your connection.

WireGuard uses UDP encapsulation with zero identifiable packet fingerprints, rendering ISP Deep Packet Inspection hardware blind.
Many cable ISPs (like Comcast and Spectrum) drop oversized packets. Setting MTU to 1420 in your VPN network settings prevents fragment re-transmissions.
ISPs log your browsing habits by inspecting default DNS resolvers. Use encrypted DoH (DNS-over-HTTPS) or your VPN’s private zero-log resolvers.
