What do RSSI, SNR and noise floor mean?
RSSI estimates received signal power; SNR compares signal with noise; noise floor reflects background energy. Stronger signal and adequate SNR generally reduce retries, but thresholds are device/use dependent.
RSSI/SNR/noise over time; retries; modulation.
RF specialist for anomalous readings.

Use platform values comparatively by client/location; avoid a single universal pass/fail threshold.
On another provider's router
Other ISP apps may expose only bars.
What to be careful of
