Frequently Asked Questions (FAQs)
Why does my phone disconnect from WiFi when the screen is off?
This is often due to power saving settings. Many phones are configured to automatically disconnect from WiFi when the screen is off to conserve battery life. Check your phone’s WiFi settings and disable any options related to “WiFi sleep policy” or “keep WiFi on during sleep.”
Why does my phone keep switching between WiFi and cellular data?
This behavior can occur when your phone detects a weak or unstable WiFi signal. It automatically switches to cellular data to maintain a continuous internet connection. Adjusting your phone’s WiFi settings to prioritize WiFi or to only use cellular when WiFi is unavailable can help. Also, ensure you are within range of the WiFi signal.
Why does my phone connect to WiFi but say “no internet”?
This typically indicates a problem with the router’s connection to the internet, not your phone itself. Verify that your router is properly connected to your internet service provider and that the internet connection is active. Restarting the router will often fix the issue.
