Overview: Wireless links
Wireless link behavior depends on radio conditions, frequency use and the paths sharing available airtime.
A strong-looking signal can coexist with interference or an inefficient shared path. Frequency-band characteristics and wireless backhaul add context beyond the client-to-access-point link. The pages here identify those radio and topology relationships before a streaming result is attributed to signal strength alone.
Wi-Fi signal quality
Wi-Fi signal quality combines received signal, interference/noise, selected radio behavior and airtime use, so RSSI alone does not predict useful media throughput.Wi-Fi frequency bands
Wi-Fi frequency bands provide different spectrum and propagation contexts, while permitted channels, device capability and actual channel conditions determine the usable link.Wireless backhaul
Wireless backhaul carries access-point traffic toward the rest of the network, with repeated use of a shared radio resource affecting end-to-end capacity.
