How to see who's connected to my WiFi on my Redmi 9

Slow page loading speeds, sudden connection drops, or simply paranoia about the security of their personal network are the main reasons why smartphone owners begin to look for uninvited guests on their Wi-Fi. This issue is especially pressing for users of popular budget models, such as Redmi 9, which are often used as the main tool for managing home Internet.

Xiaomi and Redmi owners are luckier than many other brands, as the shell MIUI (and its new version HyperOS) offers built-in tools for network diagnostics. However, to get a complete picture and, most importantly, the ability to block intruders, the phone's default settings alone may not be enough.

In this article, we will examine in detail all the available methods: from built-in security features to professional utilities from Google PlayYou will learn how to distinguish yours Redmi 9 from someone else's device in the connection list and what steps to take to protect the channel.

Checking through MIUI's built-in security features

The first place an owner should look Redmi 9, is the system's "Security" app. Xiaomi engineers have integrated a basic network scanner into it, allowing for a quick assessment of the situation without installing third-party software. This method is fast, but it doesn't always provide complete information about connected devices.

To run a scan, open the Security app (green icon with a shield) and scroll down to the "Wi-Fi Security" or "Wi-Fi Scan" section. The system will automatically scan your current connection and display the results. If the network is protected by a weak password or contains known vulnerabilities, you will see corresponding warnings.

However, it's important to understand the limitations of this method. The built-in scanner often only shows the number of connected devices, but doesn't always display their MAC addresses or names. Basic diagnostics It is useful for a quick check, but it is not suitable for deep analysis.

⚠️ Note: The menu location may vary depending on the MIUI firmware version. If you don't see the "Wi-Fi Security" option, try going to "Settings" → "Wi-Fi" and tapping the arrow next to your network name.

Using specialized scanner applications

If built-in tools aren't enough, third-party apps come to the rescue. Android-smartphones, including Redmi 9, there are many utilities that can scan a network more deeply than standard tools. The market leaders are considered to be Fing, WiFi Analyzer And Network Scanner.

Using these apps is simple: after installation, you grant geolocation access (required for Android's Wi-Fi module to work) and start scanning. The program displays a list of all devices on the network, their IP addresses, MAC addresses, and, often, the manufacturer of the network equipment.

The main advantage of these snails is the level of detail. You'll be able to see not just "Device-123," but, for example, "Samsung TV" or "Unknown Vendor." This allows you to quickly identify whether an unknown device is your smart kettle or your neighbor's phone.

The system may ask you several times to confirm access to the local network. Agree, otherwise the application will not be able to see other devices within the perimeter.

Analyzing the list of connections via the router's web interface

The most reliable and accurate way to find out who is using your Wi-Fi is to access your router's settings. Redmi 9 You can easily accomplish this task using any browser (Chrome, Yandex Browser, Mi Browser). This method gives you network administrator rights.

To log in, you need to know the gateway IP address. On a Xiaomi phone, you can find this by going to Settings → Wi-Fi → (your network name)The "Router" line will indicate the IP, usually it is 192.168.0.1 or 192.168.1.1Enter this address into the address bar of your browser.

After entering your administrator login and password (often found on a sticker underneath the router), find the "Wireless," "Wi-Fi," "Client List," or "DHCP Client List" section. This will display a complete table of all active connections with MAC addresses.

⚠️ Note: Router interfaces (TP-Link, ASUS, Keenetic, D-Link) vary significantly. If you can't find the section you need, check the manual for your specific router model, as menu names may vary.

Compare the number of devices in the list with the number of devices you have. If you see any extra devices, write down their MAC addresses. The web interface is the easiest way to block access to uninvited guests by adding their addresses to the Blacklist or disabling MAC filtering.

MAC Address and Device Correspondence Table

When analyzing the list of connections through a router or app, you'll encounter a series of numbers and letters—MAC addresses. Understanding their structure will help you quickly identify a device, even if it's labeled "Unknown."

Please note the "MAC Address Randomization" feature, which is implemented in Android 10 and later. Your Redmi 9 It can use a random MAC address for each new network to enhance privacy. This can be confusing when setting up router filtering if you're used to static addresses.

What is MAC address randomization?

This is a security feature that causes the device to generate a random address instead of the factory default when connecting to new networks. On the Redmi 9, this can be disabled in the advanced Wi-Fi settings for a specific network if the router uses MAC filtering.

Signs of unauthorized network access

How can you tell if someone is stealing your internet connection before conducting a thorough diagnostic? There are indirect signs that should alert the owner. Redmi 9Ignoring these signals may result in personal data theft or a significant reduction in connection quality.

First, pay attention to the data transfer indicator. If nothing loads on your phone or tablet, but the Wi-Fi light on your router is blinking wildly, the channel is busy. Other signs include the router heating up when idle and a decrease in response time when gaming or watching 4K video.

Another alarming symptom is the inability to connect to your own network when all devices in the house are turned off. If the router displays "Maximum clients reached," it means someone outside the home has reached the limit.

Methods for protecting and blocking other people's devices

Once you've identified the intruder, you need to act quickly. The simplest and most effective method is to change your Wi-Fi password. Once you change the access key, all devices will be disconnected, and you'll have to reconnect your devices.

A more flexible method is to use a "Guest Network." Set up a guest Wi-Fi connection for friends and visitors, while hiding your main network or using it only for trusted devices. Many routers even allow you to limit the speed of the guest connection.

If you use the ecosystem Xiaomi, check if anyone is connected via Wi-Fi Sharing. This feature allows guests to connect via a QR code, but sometimes access remains open for too long.

⚠️ Important: After changing your password or setting up MAC address filtering, be sure to reboot your router. Some devices may retain old connection settings and attempt to connect in the background, creating a load.

Setting up notifications about new connections

For constant monitoring, you can set up a notification system. Some modern routers (for example, Keenetic or ASUS with proprietary utilities) can send push notifications to Redmi 9 with each new connection.

If your router doesn't support these features, install a scanner app that can run in the background and send alerts. For example, Fing has a "Fingbox" feature (requires separate hardware) or a paid subscription for real-time monitoring.

It's also worth regularly checking the client list in the web interface, once a month. It only takes a couple of minutes, but it will give you confidence that your digital fortress hasn't fallen. Don't forget to update your router firmware, as new versions often patch security holes.

Can a neighbor hack WPA2?

Theoretically, yes, using password dictionaries and specialized utilities. Therefore, avoid simple passwords like '12345678' or your date of birth. Use a long passphrase.

Frequently Asked Questions (FAQ)

Why does my Redmi 9 show that the connection is limited even though the password is correct?

This may happen if the router has blocked your phone by MAC address or if there is an IP address conflict on the network. Try forgetting the network in the Wi-Fi settings and reconnecting, or reboot the router.

Does the app see the list of devices if I'm not connected to Wi-Fi?

No, to scan your local network, Redmi 9 must be connected to this specific Wi-Fi router. It's impossible to see home network devices via mobile internet (3G/4G) without port forwarding and complex configuration.

Are free WiFi scanners safe to use?

Most popular apps are safe, but be careful when granting permissions. Don't grant access to contacts or the microphone unless the network analysis app requires it. Read the privacy policy.

How to hide your Wi-Fi network from strangers?

You can disable SSID broadcasting in your router settings. This will remove the network from the general list, and to connect, you'll need to manually enter the network name and password in your phone's Wi-Fi settings.
