Why my laptop can't see Wi-Fi from my Redmi phone: causes and solutions

A laptop refusing to detect a hotspot created on a Xiaomi or Redmi smartphone is a common problem that often baffles users. In most cases, a device running Android MIUI successfully shares the internet, but Windows simply ignores the signal or reports that the network is not found. This can be frustrating, especially when internet access is urgently needed and a wired connection is unavailable.

The main reason is incompatibility of frequency bands or outdated network security protocols. Modern smartphones by default try to launch an access point in the range 5 GHz to ensure maximum speed, while older laptop adapters may only support 2.4 GHz. Furthermore, Windows security systems may block the connection if it appears suspicious or uses an outdated encryption standard.

In this article, we'll detail all possible technical issues that can interfere with your connection and provide step-by-step troubleshooting instructions. You'll learn how to change hidden network settings, update drivers, and reset network parameters to restore a stable connection between your devices.

Conflict between the 2.4 GHz and 5 GHz frequency bands

The most common reason a laptop can't detect Wi-Fi from a Redmi phone is that the access point is operating in the 5 GHz band. Mid-range and high-end smartphones default to this frequency because it provides higher data transfer rates and is less susceptible to interference from microwave ovens or Bluetooth devices.

However, many laptops released more than 5-7 years ago are equipped with Wi-Fi modules that support only the standard 802.11n in the 2.4 GHz band. Physically unable to scan the airwaves at 5 GHz, the computer's network adapter simply doesn't display the network in the list of available connections. This isn't a system error, but a hardware limitation.

⚠️ Note: If your laptop was manufactured before 2015, the likelihood of it supporting the 5 GHz band is extremely low. In this case, switching your phone to 2.4 GHz is the only solution.

To fix this, you need to force the smartphone's access point to switch to compatibility mode. To do this, go to the access point settings and find the "AP Band" option. Change the value from 5.0 GHz to 2.4 GHz. After this, the laptop should see the network.

Problems with network adapter drivers

The second most common cause is incorrectly functioning or outdated wireless module drivers in the Windows operating system. Even if the hardware supports the required frequencies, a software glitch can prevent proper airwave scanning. This often occurs after a major system update or installing a new antivirus.

To diagnose the problem, open Device Manager. Right-click the "Start" button and select the appropriate item. Find "Network Adapters" in the list and expand it. If a yellow triangle appears next to the name of your Wi-Fi module (usually labeled "Wireless," "Wi-Fi," "802.11," "Qualcomm," "Intel," or "Realtek"), the device is malfunctioning.

It is recommended to perform the following steps to restore functionality:

• 🔄 Right-click on the adapter and select "Uninstall device," then restart your laptop—the system will attempt to install the driver again.
• 📥 Download the latest driver from the laptop manufacturer's official website using a cable connection or another internet source.
• 🔧 In the adapter properties, on the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power."

Security settings and encryption type

Security protocols are another barrier that can hide the network from a laptop's view. Android smartphones, including Redmi models, sometimes use a mixed security type. WPA2/WPA3 or exclusively WPA3 for increased data security. Older operating systems, such as Windows 7 or earlier versions of Windows 10, may simply not understand this encryption format and ignore the network.

In your phone's hotspot settings, find "Security" or "Encryption Type." If WPA3 is selected, try switching to WPA2-Personal (AES). This is the most universal standard, supported by virtually all network cards released in the last 15 years. Changing this setting often resolves the issue immediately.

It's also worth paying attention to the network name (SSID). Some systems don't handle names containing special characters, emoji, or Cyrillic characters well. If your network is called "Internet_🏠," try renaming it to a Latin-based name, such as "Home_Network."

Hidden network and other visibility options

MIUI has a "Hide Device" feature that makes a hotspot invisible to others. When this feature is enabled, the laptop won't display the network in the general list, even if it's within range. To connect, you'll need to create a new connection manually, entering the network name and password.

Check your Redmi hotspot settings:

• 📱 Open Settings → Wi-Fi hotspot.
• 👁️ Find the "Hide device" switch and make sure it's turned off.
• 📝 Check if there is a limit on the number of connected devices (maximum 1, 2, etc.).

Why might the network disappear periodically?

A network may disappear from the list if the phone enters power-saving mode and disables Wi-Fi. In the Redmi battery settings, add the access point to the exceptions or select "Unrestricted" mode.

Resetting network settings in Windows

Sometimes the problem isn't with the phone itself, but with accumulated network settings errors in the Windows operating system itself. DNS cache, incorrect TCP/IP settings, or IP address conflicts can prevent new networks from being detected. In this case, it's best to perform a full network reset.

To do this, open the command prompt as administrator. Click Win + X and select "Windows PowerShell (Admin)" or "Command Prompt (Admin)". Enter the following commands one by one, pressing Enter after each:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

After running the last command, be sure to restart your computer. This will reset the Windows network stack to its factory default state, deleting all temporary files and resetting the configuration.

Hardware limitations and compatibility mode

There's also a nuance related to the broadcast channel. Different countries allow different channel ranges. If your phone is set to a region that uses channel 12 or 13 (common in Europe and Asia), and your laptop's Wi-Fi adapter driver is set to the US region (where only channels 1-11 are allowed), the laptop will physically not scan these frequencies.

The solution is to change the driver's regional settings. In Device Manager, select your Wi-Fi adapter, go to Properties, and then the "Advanced" tab. Find "Country Region (2.4GHz)" or "Country/Region" and try changing the value to a different one (for example, #1 (00) or a specific country). This may require some experimentation.

⚠️ Note: The driver settings interface may differ depending on the chip manufacturer (Intel, Atheros, Realtek). If you are unsure of what you are doing, it is best not to change these settings unless absolutely necessary.

Also worth mentioning is the mode 802.11ax (Wi-Fi 6), which is supported by new Redmi devices. Some older adapters may not work correctly with beacon frames of newer standards. In the phone's access point settings, you may sometimes find an option called "Compatibility mode" or "Use compatible AP"—enabling this feature forces the phone to emulate older communication standards.

Frequently Asked Questions (FAQ)

Why can my laptop see other Wi-Fi networks but not the access point from my phone?

The problem is most likely related to the frequency range. Routers at home often operate in mixed mode or on 2.4 GHz, while your phone defaults to 5 GHz. It's also possible that the network name contains invalid characters for your adapter.

Can antivirus software block a phone's hotspot connection?

Yes, some security features in third-party antivirus programs (Kaspersky, ESET, Avast) may classify a mobile hotspot as a "Public Network" and block its detection for security reasons. Try temporarily disabling your antivirus's firewall.

What should I do if my laptop stops detecting Wi-Fi after updating MIUI?

Firmware updates often change default settings. Check if your password has been reset, if the device hiding feature has been enabled, or if the frequency band has been changed to 5 GHz. Also, try forgetting the network on your laptop and reconnecting.

Will rebooting both devices help?

In 70% of cases, a simple reboot of the smartphone or laptop resolves the issue. This clears the temporary cache of network modules and forces them to re-initiate the handshake and exchange discovery packets.
