Problems with Wi-Fi on smartphones are quite common. There are a lot of questions on the forums, with the wording “Xiaomi Redmi 3S Wi-Fi does not turn on, what should I do?” The question is quite relevant, so the answer can be found in this article.
The first thing to check is the availability of the Internet as such. Verification is best done using another device: laptop, smartphone, tablet. it doesn’t matter. All that is needed from them is a check of the router’s operability and the presence of an Internet signal as such. If it is not there, the problem does not apply to our router or smartphone. After verifying this, you should immediately dial the support service number.
Situation one: connection settings failed
Diagnosing this is very easy:
- Open the settings;
- Select Wi-Fi;
- Make sure the module is active;
- We are looking for our network;
- Check the connection to it;
If the smartphone is in the right network. everything is fine, you need to go to the next step. If not, then try to connect to it. Usually, this helps, otherwise we “forget” the connection, after which we try to implement it again. Did not help? Reboot the device. If nothing comes out again, we proceed to a more complex solution to the problem: changing the type of encryption of the router.
By default, all manufacturers install WPA2 PSK channel encryption for most of their routers, which allows to achieve high security indicators, however, it can cause network problems on mobile devices. To solve them, open the router settings through a browser and change the encryption to just WPA or WDS. Standards checked, the problems should go away.

If the phone again refuses to connect to the network, go ahead and change the signal frequency from b \ g \ n to b \ g, check the region is correct.
Sometimes, the provider blocks the distribution of the Internet for devices where the region is incorrectly defined. After that, the smartphone should definitely connect. You can also try changing the distribution channel from 1 to 11, but this helps very rarely.
Situation two: the smartphone connects to the network, but cannot access the Internet
Most often, a failure occurs due to working DHCP. the protocol for automatically obtaining an IP address, which is hidden in the advanced network settings. We open them, find the corresponding item and disable the protocol, if necessary, put a tick in front of the item “use static IP” and enter the desired value, which is taken from the router.
How does DHCP interfere with the internet? If the provider gives you a permanent ip-address, and the smartphone tries to periodically pick up a new one, because of which the Internet becomes impossible. When using dynamic addresses, everything should work stably, without unnecessary “tricks”.
The second probable obstacle may be an empty network proxy, due to which, for example, Xiaomi Redmi Note 3 Pro does not connect to Wi-Fi. To solve this problem, open the advanced settings again, put a tick in front of the item “advanced settings” and select the empty field or “no”.
There are also special programs for smartphones that allow you to configure the network "without too much noise": Wifix Manager, Wifi Fixer and others. They manage the parameters of the wireless connection, collect all the settings in one place, which is undoubtedly convenient, automatically diagnose and fix problems, if they, of course, relate to the software part of the device.
