If you have a tariff plan with very limited data traffic - let's say a couple of gigabytes or so - you certainly know how frustrating it is to deal with an iPhone that has difficulty connecting - or does not connect at all - to the Wi-Fi network -Fi from home, the office or the bar we usually go to. Not a small problem, the Wi-Fi that does not connect: if we have to download iOS updates, watch a movie or listen to music in streaming or download large files, the wireless connection to the home network is an obligatory choice , almost.
Luckily, fixing iPhone Wi-Fi connection problems isn't too complicated. In the vast majority of cases, in fact, it will be enough to carry out small maintenance operations and change some settings of the iPhone to go back to connecting to the wireless network. Let's see together what to do to solve iPhone Wi-Fi connection problems.
Check that the Wi-Fi is active
The first thing to do when the Wi-Fi does not connect is to check that the function is active on our iPhone. And, secondly, that the wireless network to which we want to connect is visible in the list of available connections. We open the control center of the iPhone - just a swype from bottom to top - and check that the Wi-Fi icon is colored; otherwise, press on the icon and wait a few seconds for it to activate and connect. While we're at it, let's also take a look at the airplane mode icon: maybe we activated it during the night so as not to be disturbed and forgot to deactivate it.
For a more in-depth check, we can open the iPhone Settings, press on Wi-Fi and see if the wireless connection switch is on "On" or "Off". Furthermore, from here we can also verify that the Wi-Fi network to which we would like to connect is available or not. Perhaps the problem of Wi-Fi not working does not depend on the iPhone, but on problems with the router or telephone line.
Enter the Wi-Fi password
If, after activating the iPhone's Wi-Fi, we still have problems connecting to the network, we can try to check whether or not the Wi-Fi is password protected. To check, just open the Settings, press on Wi-Fi and then press on the network to which you would like to connect: if it asks for the password, enter it and wait for the synchronization between the two devices.
If the iPhone still can't connect, keep your finger pressed on the "offending" Wi-Fi network and choose Forget this network in the window that appears. After a few moments, the network should appear again in the list of available ones: press the name again and enter the Wi-Fi password.
Force restart your iPhone
Wi-Fi connection problems can also be caused by a temporary bug or glitch in your iPhone's operating system. For this, it is advisable to perform a forced restart of the iPhone, which will terminate all active processes on our device and guarantee us a "clean" start. For the forced restart, just hold down the Home button and the shutdown button simultaneously, until the Apple symbol appears on the display: at this point you will have to release the combination of buttons and wait for the operating system to finish loading.

To do this, open the iPhone Settings, then General, Reset and Reset network settings. This will also delete your Wi-Fi networks and passwords, cellular settings, and previously used VPN and APN settings. In short, a clean slate will be made of everything we had done and saved regarding network connections, both in terms of cellular networks and Wi-Fi.
Disable location services
Wi-Fi, unlike what we might think, is not just for surfing online. The iPhone (but also Android smartphones) use it to improve the accuracy with which they locate us on maps, thus managing to provide us with better location services. However, this can also affect the performance of the wireless connection, so much so that the Wi-Fi could even suddenly stop working. If desired, however, we can deactivate this particular location service without compromising the correct functioning of the GPS location.
Open the iPhone Settings, choose Privacy, Location and scroll down the screen until you find System Services. Here we identify the item Wi-Fi network and deactivate it, in case it is used to improve our localization.
Restore the iPhone to factory settings
If none of the tricks described so far has made it possible to get the iPhone's Wi-Fi working again, we just have one last card left to play: reset the device to the factory settings. First of all, make sure you have backed up the data in memory (photos, videos, messages, documents, etc.) so that you can recover them later; otherwise take some time to complete this step.
Once the iPhone backup is done, open the iPhone Settings, press on General and then Restore. Here we choose Initialize content and settings and wait for the operation to complete. If the Wi-Fi does not work again at this point, it is very likely that it is a hardware problem and therefore the only solution is to contact the Apple service center closest to you.
