Recognize these? Here's what usually causes it.

- router firmware behavior change
- 2.4GHz channel/compatibility shift
- DHCP/session handling instability
Most fixes happen in the first 3 steps.
Do not reset all Sonoff devices before validating router compatibility regressions.
Tools & Requirements
Step-by-Step Solution
Identify update-related changes
Review router firmware release changes affecting 2.4GHz/IoT behavior.
Apply stable WiFi profile
Use conservative channel/security settings for IoT clients.
Validate reconnect rates
Monitor device uptime and command reliability after adjustments.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the device became unresponsive after a firmware update, a factory reset usually clears the corrupted state — the update itself is rarely the root cause.
Router firmware updates should include post-update IoT stability checks.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
