If your iPhone 6s started losing Wi-Fi signal after installing iOS 13, you’re not alone. Many users have experienced the same frustrating issue—random disconnections, weak signal strength, or constant reconnecting. Fortunately, there are several fixes you can try before deciding it’s a hardware problem.
Here’s a step-by-step guide to help stabilize your iPhone 6s Wi-Fi connection.
✅ Start with These Quick Checks
- Move closer to your router – A weak signal leads to more frequent dropouts.
- Remove any bulky case – Some cases interfere with wireless signals.
- Avoid interference – Microwaves, thick walls, and wireless cameras can all mess with your Wi-Fi.
Still dropping? Start the real fixes below.
1. Restart Your Modem or Router
Many “Wi-Fi problems” start with the router—not your iPhone.
To power cycle your router:
- Turn off the router/modem using the power button.
- Unplug it from the power outlet for at least 1 minute.
- Plug it back in and turn it on.
- Wait for the signal to stabilize, then reconnect your iPhone.
2. Soft Reset Your iPhone 6s
A simple reboot can fix glitches introduced by the iOS update.
To restart:
- Hold the Side (Power) button until you see the Slide to Power Off.
- Slide to turn off.
- After 30 seconds, press the Side button again to restart.
3. Toggle Wi-Fi Off and On
A quick Wi-Fi refresh can fix temporary disconnects.
- Go to Settings > Wi-Fi
- Toggle the switch Off, wait 5–10 seconds, then turn it Back On
- Reconnect to your network
You can also do this from the Control Center by tapping the Wi-Fi icon.
4. Try the Airplane Mode Trick
This refreshes all wireless radios at once.
- Go to Settings > Airplane Mode
- Toggle Airplane Mode ON
- Restart your iPhone
- After rebooting, turn Airplane Mode OFF
- Reconnect to your Wi-Fi
5. Forget and Re-Add Your Wi-Fi Network
Your saved network might be corrupted after the update.
To reset the connection:
- Go to Settings > Wi-Fi
- Tap the “i” icon next to your network
- Tap Forget This Network
- Reconnect by entering your Wi-Fi password
6. Reset Network Settings
This will erase saved networks, VPNs, and cellular settings.
- Go to Settings > General > Transfer or Reset iPhone > Reset
- Tap Reset Network Settings
- Enter your passcode to confirm
Your iPhone will restart and reset all network configurations. Reconnect to Wi-Fi and test stability.
7. Factory Reset (Last Resort)
If nothing else worked, a full reset may be needed to fix corrupted system files.
⚠️ Backup your data first!
- Go to Settings > General > Transfer or Reset iPhone
- Tap Erase All Content and Settings
- Set up your iPhone as new (don’t restore from backup just yet)
- Test your Wi-Fi before restoring anything
Alternatively, you can do this using iTunes on your computer.
Still Dropping Wi-Fi? Here’s What to Do Next
- Call your internet provider – Ask if there’s a signal issue or outdated router firmware.
- Test with another Wi-Fi network – This helps isolate if the issue is with your iPhone or your router.
- Contact Apple Support – There may be an iOS 13 bug affecting connectivity, or your iPhone could have a hardware issue (like a failing Wi-Fi antenna).
