Internet guides, hardware reviews, latency optimization, and speedrun tips for the modern web.
A bufferbloat grade summarizes added latency during transfers. It is not a score for download speed, idle ping or every internet activity.
Stuck on Moderate or Strict NAT? We explain how Carrier-Grade NAT (CGNAT) shares IP addresses across thousands of homes, breaking multiplayer hosting, port forwarding, and voice chat.
Is 50ms ping good or bad? We grade gaming latency across tactical shooters, fighting games, and MOBAs, explaining tickrate windows, jitter thresholds, and loaded ping.
Latency describes response time; jitter describes variation in latency. Neither is universally more important, and jitter is not meaningfully described as always ten times worse.
Screen mirroring freezing or smart speakers disappearing from your phone? We explain mDNS broadcast flooding, Wi-Fi multicast drop rates, and how to fix smart casting.
Seeing a 'Weak Security' amber warning on your iPhone Wi-Fi settings? We explain WPA2/WPA3 Transitional Mixed-Mode, TKIP deprecation, and how to fix it.
Do your iPhone or MacBook drop Wi-Fi when walking between rooms? We explain Apple's aggressive roaming threshold (-70 dBm), Private MAC address collisions, and how to fix it.
Watching Netflix, YouTube, or Prime Video and the audio keeps playing perfectly while the video freezes on a loading wheel? We explain the telecommunications science behind media buffering.
Paying for high-speed 500 Mbps internet but still rubber-banding in games and buffering on Zoom? We explain why bandwidth has nothing to do with gaming latency and how to fix lag.
