Why Wi-Fi is not connected on the Xiaomi Redmi phone: reasons and solutions

A situation where your Xiaomi Redmi suddenly stops seeing wireless networks or endlessly tries to connect to a well-known router can unbalance any user. MIUI HyperOS, or hardware features, can cause the communication module to work in an unstable way, most often because of conflicting power saving settings or errors. DHCP-servers that are easily fixed by software.

However, if the phone persistently writes “failed to connect” or the Wi-Fi icon just disappeared from the notification curtain, you can’t ignore it. This can be a sign of both a banal firmware failure and more serious hardware damage to the antenna module after falling or getting moisture. In this article, we will analyze all possible scenarios, from simple reboots to complex manipulation of the engineering menu to return your gadget to stable Internet access.

It's important to understand that diagnostics starts with the exclusion of external factors. Before you go into deep system settings, make sure that the problem is in the phone, not the router or the provider. Try connecting another gadget to the same network: if there is Internet there, then you need to dig in the direction of your Android device.

Basic diagnosis and rapid elimination methods

The first step is always to "softly" reboot the system. Unlike just turning off the screen, a full reboot clears RAM and restarts all system services, including the wireless module drivers. Often this is enough to reset the hung connection process. If a simple reboot does not help, try to switch flight mode: activate it for 10-15 seconds, and then turn it off. This action forcibly reconnects all the radio modules of the phone.

Another effective method is to forget the problem network, and the system might have saved the wrong authorization settings or the old password, go to the Wi-Fi settings, click on your network name, and select Delete or Forget the network, and then re-enter the password. MAC-Addresses in a particular network settings on “Random” because some routers block devices with altered or conflicting identifiers.

And don't forget the trivial lack of resources. If you have dozens of apps on your phone, it can aggressively restrict the background activity of network services to save power. Close the extra tabs and try again. Also check if you have a third-party "Internet speed" app or VPN that can block the connection.

⚠️ Note: If after the reboot the Wi-Fi icon is completely gone (even when it is off, it is not in the settings list), this is likely to indicate a hardware dump of the module or its plume.

Software resetting of network settings

If simple methods fail, you need to do a deeper reset of your network settings, which will bring all your connection settings (Wi-Fi, Bluetooth, mobile Internet) back to factory values. It's important to note that your personal files, contacts, and photos won't be deleted, but you'll have to re-enter passwords from all Wi-Fi networks and re-connect your Bluetooth headphones or watches.

To perform this operation on Xiaomi Redmi, you need to go to the settings menu.The path may vary slightly depending on the version of MIUI, but it usually looks like this:

Settings → Connection and Sharing → Reset Wi-Fi, Mobile Networks and Bluetooth

Once this is selected, the system will ask you to confirm the action by entering the unlock password or the pattern lock. Once confirmed, the phone will automatically restart. This method is especially effective when errors have accumulated in the network configuration files that interfere with normal communication. DHCP-data exchange with the router.

There's also a hidden test menu that you can access through dialing, and by entering ##6484##, you'll be taken to the CIT engineering menu, where you can select "WiFi" and start testing the module, and if the test shows an error or freezes during the scan phase, the problem is hardware-based.

Conflicts IP-addresses and settings DHCP

One of the common reasons why a phone sees the network but can’t access the internet is because of conflict. IP-The router may not give a new address to the device if its record rental table already has a device with the same address. MAC-If you're using the address, or if you're running out of addresses, then you can use manual adjustment. IP-address.

To change settings, click the arrow next to your Wi-Fi network name in the list of available connections (or select Change Network). Under IP Settings, switch from DHCP to Static. You will need to enter the following data (example, depending on your router):

• 📍 IP-address: 192.168.1.128 (last digits can be changed from 2 to 254)
• 📍 Gateway: 192.168.1.1 (usually the router's address)
• 📍 Length of network prefix: 24
• 📍 DNS 1: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)

Use of public use DNS-servers such as Google or Cloudflare often solve long-term problems. IP-Providers sometimes respond slowly to their requests. DNS, That's what causes the phone to time out. DNS Faster alternatives can speed up the connection process at times.

If and after the manual registration IP-no connection, check if the router is filtered by MAC-Your Xiaomi may have been accidentally blocked in the router's security settings.

Impact of energy saving and MIUI optimization

The MIUI shell and the new HyperOS are known for their aggressive power optimization, which can kill the Wi-Fi process as background and energy-intensive, especially if the battery is low, causing the phone to periodically lose the network or even refuse to turn on the module.

To rule out this factor, check your battery settings. Go to Battery and Performance (or simply Battery) and find your energy saving settings. Make sure Balanced or Performance mode is on, but Ultra-Savings mode is off. Also, in your application settings, find the Wi-Fi system app (if available in your firmware version) and allow it to auto-start and run in the background without restrictions.

Another reason could be the date and time settings: If the phone has a date that is lost (for example, it is 2020), security protocols (WPA2/WPA3) will not be able to pass authorization, since security certificates will be considered invalid.

⚠️ Note: Some memory cleaners and third-party antiviruses may block network activity as suspicious.

Problems with frequency bands and router

Modern Xiaomi smartphones support the 2.4 GHz and 5 GHz bands. However, older models or devices with defective antennas can not catch a 5 GHz signal, especially through walls. If the router broadcasts networks with the same name (Smart Connect), the phone may try to cling to a weak 5 GHz signal instead of a stable 2.4 GHz.

Try splitting networks in router settings by giving them different names (e.g, Home_2G and Home_5G), and connect the phone to the range 2.4 GHz. It's more range-wise, it's better at breaking through obstacles. It's also worth checking the channel, if your neighbors have routers running on the same channel, you'll get interference. Use Wi-Fi analytics apps to find a free channel.

In some cases, changing the region in the router settings helps. Signal power standards vary from country to country. Installing a region called the U.S. or Australia (where more power is allowed) sometimes works wonders, but it depends on the router model. On the phone side, you can try changing the region in the "Additional" → "Region" menu, although this affects system applications primarily.

💡

Use the Wi-Fi Analyzer app to see how busy the air is. If all channels are clogged, only rebooting the router with a change in the broadcast channel to free will help.

Hardware malfunctions of the Wi-Fi module

If none of the software methods worked, and the phone doesn’t see any network even in the vicinity of the router, it’s likely the hardware that’s the problem. In Xiaomi Redmi smartphones, the Wi-Fi module is often integrated into a shared board or made as a separate chip that’s soldered to the motherboard.

The main causes of hardware breakdowns:

• 🔨 Mechanical damage: A phone fall could have caused chip contacts to detach (dump) or damaged the antenna plume.
• 💧 Moisture: Even a small amount of condensate inside the housing causes the antenna module contacts to oxidize, resulting in signal loss.
• 🔥 Overheating: Prolonged play or charging in hot conditions could lead to degradation of soldering under the chip Wi-Fi/Bluetooth.

You can diagnose this by gently pressing the back cover at the top of the phone (where the antenna is usually located) while searching for networks. If networks appear and disappear, contact is broken. Also, a sign of breakdown is a gray or inactive Wi-Fi icon in the settings that cannot be turned on.

💡

If the Wi-Fi test ends with a Failed error in the Engineering Menu (CIT), and the factory reset does not help, a replacement of the chip or antenna module in the service center is required.
