How to Fix WiFi Not Working on Android: Step 1 – Restart Router and Phone

Over 70% of WiFi not working on Android issues resolve with a simple restart. This clears temporary cache, resets network conflicts, and refreshes the connection between your device and router.

1. Unplug your WiFi router from power for 30 seconds.
2. Restart your Android phone (hold power button → Restart).
3. Plug the router back in and wait for all indicator lights to stabilize.
4. Reconnect your phone to WiFi and test internet access.

Pro Tip: Place your router in an open, elevated area — avoid corners, cabinets, or near microwaves, cordless phones, or Bluetooth devices that cause interference.

How to Fix WiFi Not Working on Android: Step 2 – Forget and Reconnect to WiFi Network

Saved WiFi profiles can become corrupted over time, leading to authentication failures. Forgetting the network forces a fresh connection and often resolves WiFi not working on Android instantly.

1. Go to Settings → Network & Internet → WiFi.
2. Tap your network name → Forget.
3. Tap the network again and enter the correct password.
4. Wait 10–15 seconds and check if internet works.

If other devices also can’t connect, the issue is with your router or ISP — not your phone.

How to Fix WiFi Not Working on Android: Step 3 – Reset Network Settings

This resets WiFi, mobile data, and Bluetooth configurations without deleting apps or photos. It’s one of the most effective ways to fix WiFi not working on Android caused by misconfigured settings.

1. Open Settings → System → Reset options.
2. Select Reset WiFi, mobile & Bluetooth.
3. Confirm and restart your phone.

Note: You’ll need to re-enter WiFi passwords after this step.

How to Fix WiFi Not Working on Android: Step 4 – Update Android Software

Google releases monthly security patches that fix known WiFi bugs. Outdated firmware is a common reason for WiFi not working on Android in 2025.

1. Go to Settings → System → Software update.
2. Tap Check for updates.
3. Download and install any available updates.
4. Restart your phone after installation.

Tip: Use mobile data or a friend’s hotspot to download updates if WiFi is down.

How to Fix WiFi Not Working on Android: Step 5 – Change DNS to Google or Cloudflare

Your ISP’s DNS servers are often slow or unreliable. Switching to public DNS fixes “connected, no internet” and speeds up browsing — a proven method to fix WiFi not working on Android.

1. Go to WiFi settings → Tap your network → Advanced.
2. Change IP settings from DHCP to Static.
3. Enter:
   • DNS 1: 8.8.8.8 (Google)
   • DNS 2: 8.8.4.4

   Or use Cloudflare: 1.1.1.1 and 1.0.0.1

4. Tap Save and reconnect.

How to Fix WiFi Not Working on Android: Step 6 – Eliminate Signal Interference

Physical barriers and electronic interference are major causes of WiFi not working on Android. Use a free WiFi Analyzer app from Google Play to:

• Detect crowded channels
• Switch to channel 1, 6, or 11 (2.4GHz) or 36–48 (5GHz)
• Identify interference from neighbors or devices

Move closer to the router, remove phone case, and avoid thick walls or metal surfaces.

How to Fix WiFi Not Working on Android: Step 7 – Disable Battery Saver & Power Modes

Battery optimization kills background WiFi processes to save power. This causes frequent drops and is a silent reason for WiFi not working on Android.

1. Go to Settings → Battery → Battery Saver → Turn OFF.
2. Tap Battery usage → Find WiFi-related apps → Set to Unrestricted.
3. On Samsung/Xiaomi: Disable Adaptive Battery and Performance Mode.

How to Fix WiFi Not Working on Android: Step 8 – Set Static IP Address

DHCP conflicts prevent internet access even when connected. Assigning a static IP bypasses this and stabilizes your connection.

1. WiFi → Tap network → Advanced → IP settings → Static.
2. Enter:
   • IP: 192.168.1.150
   • Gateway: 192.168.1.1
   • DNS 1: 8.8.8.8
   • DNS 2: 8.8.4.4
3. Save and reconnect.

How to Fix WiFi Not Working on Android: Step 9 – Boot in Safe Mode

Third-party apps (VPNs, cleaners, ad blockers) can interfere with WiFi. Safe Mode disables them temporarily.

1. Press power button → Long-press “Power off” → Tap Safe Mode.
2. If WiFi works → uninstall recently installed apps.
3. Restart normally to exit Safe Mode.

How to Fix WiFi Not Working on Android: Step 10 – Factory Reset (Last Resort)

Backup everything first! A factory reset eliminates deep software corruption, malware, and conflicting system files — fixing WiFi not working on Android in 95% of persistent cases.

1. Go to Settings → System → Reset options → Erase all data.
2. Confirm and wait for completion.
3. Set up your phone and test WiFi.
