Today we have a large dependence on mobile data networks and WiFi. Thanks to them we access the Internet from our iPhone and when they fail it is a very big problem.
In the case of data networks, there is not much you can do, since as a general rule the faults are on the side of the telephone operator and they are the ones that must solve it as soon as possible so that you can continue using the service we have contracted.
With WiFi networks, the aforementioned also occurs, but there is also another series of possible configuration problems in our devices or routers that we can easily solve on many occasions. In the following lines, we want to talk about the most common problems that cause the WiFi of the iPhone, iPad or iPod Touch does not work and the solutions to these problems.
As I said, WiFi problems on iPhones are usually configuration problems, that is, software problems. In a way, this is fortunate, as we ourselves can try to solve them without having to resort to third parties as would happen in case of hardware failure (something that can also happen but is much less common).
What to do when your iPhone does not connect to WiFi
The usual WiFi problems of iOS devices are slow or do not directly connect to the Internet. In both cases the possible solutions are usually the same:
Turn off and turn on the device’s WiFi
The old trick of turning on and off is also here. It’s the first thing to try when a WiFi goes slow or does not work directly: turn off and turn on the WiFi on the device. For this, the most advisable is to access Settings – Wi-Fi and slide the Wi-Fi switch to off and then turn it on again.
In this simple way, it is possible that some connectivity problems are solved and as you have been able to see it will not take you more than a few seconds; so it does not hurt to try if this solves the problem.
Restart the iPhone
In some cases, the software that controls the Wi-Fi connectivity of the iPhone fails and it may be necessary to restart certain processes. Since iOS does not allow us to control processes individually, the only thing you can do is to completely restart the iDevice.
After the restart, the wireless connection should return to normal operation, at least if it was a problem caused by a software error.
Delete the WiFi network and reconfigure it
This is usually the definitive solution to the problems of slow Wi-Fi connections. Generally, this failure is caused by configuration changes of the router or Wi-Fi hotspot and therefore deleting it and reconfiguring it in the device that can not be connected solves the problems.
To do this you must access Settings – Wi-Fi and touch the blue icon with the i that appears next to the name of the network. Once inside the network settings, tap on Skip this network. After doing this connect back to the network (you will have to enter the password again) and check if the fault has been solved.
Renew the DHCP lease
In rare cases you may be connected to a network in which the DHCP server has not assigned you an IP address correctly or has given you a duplicate (one that is using another device, this can happen in networks with many connected devices and a DHCP server that is not powerful enough to manage that network).
To solve this problem you can go to Settings – Wi-Fi , touch on the blue icon with the i and then touch on Renew concession. The network will assign you a new IP and if everything went well you can use the WiFi network without a problem.
Reset network settings
Access Settings – General – Reset and choose the option Reset network settings. By doing this all the configuration related to the WiFi network and mobile data of the device will be removed and restored to its default state.
This can solve some problems of the WiFi network, but it will also mean that once restored you will have to reconfigure all the settings manually.
Restore iPhone, iPad or iPod Touch to factory state
The last option before thinking about a hardware failure of iOS devices is to do a full restoration of the iDevice. Doing this supposes to eliminate all the data, apps and configurations of the equipment, so it is highly recommended to try with the previous options before entering to value this option.
Of course, if you finally need to resort to full computer restoration do not forget to make a full backup before using iTunes or iCloud to keep all device data safe.
These are the most common solutions to WiFi connectivity problems that may arise on an iPhone, iPad or iPod Touch.
