Android software updates bring new features, security patches, and performance improvements, but they can sometimes cause network problems. Users may experience slow internet, dropped Wi-Fi connections, or mobile data not working after an update.
Fortunately, most network issues can be fixed with simple troubleshooting steps without needing technical expertise. This guide explains why network problems occur after updates and provides practical solutions.
Restart Your Phone
After a software update, temporary glitches can affect network connectivity.
Fix: Restart your Android device. Rebooting resets network settings, clears minor software bugs, and often restores stable Wi-Fi and mobile data connections immediately.
Toggle Airplane Mode
Airplane Mode temporarily disconnects all wireless connections, which can help resolve post-update network issues.
Fix: Swipe down from the notification panel, enable Airplane Mode for a few seconds, and then disable it. This refreshes your mobile and Wi-Fi connections.
Forget and Reconnect to Wi-Fi Networks
Saved network settings from before the update may conflict with new software configurations.
Fix: Go to Settings → Network & Internet → Wi-Fi → Saved Networks → Select Network → Forget, then reconnect by entering your password. This ensures a fresh connection.
Reset Network Settings
Software updates can sometimes corrupt network settings, causing connectivity issues.
Fix: Navigate to Settings → System → Reset Options → Reset Wi-Fi, Mobile & Bluetooth. This resets all network settings without affecting personal files. Reconnect to Wi-Fi and mobile networks afterward.
Check SIM Card and Mobile Data
Updates may reset APN settings or mobile data configurations.
Fix: Ensure your SIM card is properly inserted. Go to Settings → Network & Internet → Mobile Network → Access Point Names (APN) and verify your carrier’s APN settings. Update them if necessary.
Disable VPNs or Proxy Connections
VPNs and proxies can interfere with network performance, especially after software updates.
Fix: Disconnect from VPNs or proxies and check if the network improves. Only reconnect when privacy or security requires it.
Update Carrier Settings
Carrier settings updates often accompany Android system updates. Missing or outdated carrier settings can affect mobile network functionality.
Fix: Check for carrier settings updates via Settings → About Phone → Carrier Settings and install any available updates.
Check for Pending System Updates
Occasionally, the first update may have bugs affecting connectivity, and manufacturers release quick patches to fix them.
Fix: Go to Settings → System → System Update and ensure your phone has the latest updates installed.
Limit Background Data Usage
Post-update, some apps may behave differently, consuming more data in the background.
Fix: Go to Settings → Network & Internet → Data Usage → Background Data and restrict apps that don’t need continuous internet. This prioritizes active connections for better performance.
Reset Router or Modem
If Wi-Fi issues persist, the problem may be with your network rather than your phone.
Fix: Turn off your router/modem, wait 30–60 seconds, and turn it back on. Reconnect your phone and test the connection.
Clear Cache Partition (Optional)
Sometimes, leftover system cache from the update can cause network instability.
Fix: Boot your device into recovery mode and clear the cache partition. This doesn’t delete personal data and can resolve persistent connectivity problems.
FAQ Section
Why does my Wi-Fi stop working after an update?
Updates can reset network settings or introduce bugs. Restarting, reconnecting, or resetting network settings usually resolves the issue.
Will resetting network settings delete personal files?
No. It only resets Wi-Fi, mobile data, and Bluetooth settings.
Can a software update break mobile data?
Yes, if APN settings or carrier configurations are changed. Reconfiguring or updating carrier settings usually fixes it.
Do VPNs affect network after updates?
Yes. VPNs can cause slow or unstable connections, especially if not compatible with the new software version.
Should I clear cache after an update?
Clearing the cache partition can fix lingering bugs and improve performance, including network connectivity.
Final Thoughts
Network issues after Android software updates are common but usually easy to fix. Restarting your device, reconnecting to Wi-Fi, resetting network settings, verifying APN configurations, and updating carrier settings typically restore normal connectivity. Regularly checking for system updates and maintaining good network practices ensures your Android phone remains fast, reliable, and fully functional after software updates.
