SSID vs BSSID: Wi-Fi Network Names and Radio Identities Explained
Explain why one network name can appear through many radios and MAC-like identifiers.

Compare Wi-Fi generations by spectrum/features and realistic upgrade impact instead of maximum marketing rate.
Modern phones and computers can use a different MAC address for a Wi-Fi network to reduce passive tracking. That changes how router reservations, parental controls, and device lists behave.
Dynamic Frequency Selection lets Wi-Fi share parts of 5 GHz spectrum with protected radar systems, which can create waits or channel changes that look like random Wi-Fi trouble.
Wider channels can raise peak throughput but consume more spectrum and can reduce reliability or reuse in congested environments.
Your device-to-router radio link and your modem/ONT-to-ISP access link can fail independently. Learn which indicators belong to which path.
The router and the laptop/phone/server enforce policy at different points. One is not a complete substitute for the other.
Both approaches can produce a predictable LAN address, but they place responsibility in different places and have different maintenance consequences.
Understand how a mesh system extends coverage, why node placement matters, and when wired backhaul is worth using.
Understand personal-mode Wi-Fi security, transition mode, device compatibility, and why a strong unique passphrase still matters.
