Solution 1. Turn WiFi Off and Back On
This simple fix resolves many connection issues. Start by checking if the WiFi icon appears in your status bar. If not, your connection may have dropped.
To toggle WiFi:
- Go to Settings > WiFi
- Toggle the switch next to WiFi off, wait a few seconds, then turn it back on
If this doesn't work, check your router. Look for indicator lights showing internet connectivity. If the router appears offline, restart it by unplugging for 30 seconds, then plugging back in.
Solution 2. Toggle Airplane Mode
Airplane mode disables all wireless connections, including WiFi. If it's accidentally enabled, your iPhone won't connect to any networks.
To reset connections:
- Go to Settings and turn Airplane mode on
- Wait 30 seconds
- Turn Airplane mode off
- Try connecting to WiFi again
Solution 3. Check WiFi Assist Settings
WiFi Assist automatically switches to cellular data when WiFi connectivity is poor. While helpful, it can sometimes prevent proper WiFi connections.
To adjust WiFi Assist:
- Navigate to Settings > Cellular
- Scroll down to find WiFi Assist
- Toggle it on or off as needed
Solution 4. Restart Your iPhone
A simple restart can clear temporary software glitches affecting WiFi connectivity.
To restart:
- Press and hold the sleep/wake button or power + volume down buttons
- Drag "Slide to Power Off" to turn off your iPhone

Solution 5. Disable VPN Apps
VPNs can interfere with WiFi connections, even when not actively in use.
To disable VPN:

Solution 6. Restart Your Router and Modem
If your iPhone connects to other WiFi networks but not your home network, the router may be the issue.
To restart networking equipment:
