1. RestartNow this is the simplest solution that anyone should try if they can’t successfully log in to the WiFi.
- Try putting your phone in Flight Mode and then turn Flight Mode off.
- Try restarting your iPhone by turning it off using the Power button. Give it some time to turn off and then press and hold the Power button again to turn it on. Probably after waiting for 20-30 seconds, your connection error may be rectified.
- If no device is getting connected to WiFi, the problem is with the router. Make sure that your router is working correctly and try turning it off and on.
2. ResetYou can try resetting the current WiFi configuration. To do this, follow some simple steps:
- Tap on Settings, the gear icon in your iPhone menu.
- Tap General followed by Reset.
- Select Reset Network Settings.
- Tap on Settings>General>Reset>Reset all Settings.
3. Join AgainResetting network settings may not work at times. Resetting all the settings is too much to ask for as you will lose all your preferences at once. So it is better that you forget the network and join again. This can be done easily.
- Tap on Settings. Select WiFi.
- The available channels will be shown and choose the network.
- Tap on Forget this network option. The WiFi network will be disconnected. You can join again to this network manually.
4. ReconfigureUsually, the PC, desktop or phone devices connect to the internet by obtaining the IP address, subnet mask, and DNS automatically. But for some routers or the WiFi network you have connected might be configured to a particular network configuration. This would mean that the IP address, DNS must have some static value. So you will have to enter this value manually to connect to the WiFi. To do this:
- Open Settings and choose the WiFi network.
- Select the option Static instead of DHCP.
- Give the values in the columns. Usually, a DNS address like 220.127.116.11 will work if your network provider has not given you the router configuration before. So try using it.
5. UpdateMake sure that your iPhone is equipped with the latest software update. To check if any new iOS update is available:
- Go to Settings>General>Software update.
- If a new update is needed, it will be shown. After updating your phone, connect to the WiFi.
ConclusionThese are the little tweaks you can try on your phone to fix the error. But every phone is different and might be dealing with a different problem which might be preventing a WiFi connection. If nothing works, try contacting the Apple Support Team to get your issue resolved.
Even if these methods don’t fix your issue completely, you will at least know whether the problem is with the phone or the router so that you can bring it to the attention of experts. Hope it helps.
