Jasmine Mannan writes that home Wi-Fi performance issues like buffering or high latency are often caused by airtime exhaustion rather than insufficient bandwidth. A single device flooding the local domain with excessive multicast or broadcast traffic forces routers to transmit these packets at very low legacy speeds, consuming significant radio frequency time and overwhelming the network for all other users.
- Common culprits include misconfigured IPTV boxes, printers, and chatty IoT microcontrollers.
- Enabling IGMP snooping can mitigate multicast storms by limiting traffic to specifically requested ports.
- Creating a separate VLAN or guest network helps isolate problematic devices from main high-speed hardware.
- Packet capture tools like Wireshark can be used to identify the specific IP address causing flooding.
