How to Create a Guest Network on Xiaomi Mi Router AX1800: A Step-by-Step Guide That Actually Works In the era of smart homes and remote work, network security has never been more critical. Every time a friend, family member, or contractor asks for your Wi-Fi password, you are effectively handing them the keys to your entire digital kingdom. They can potentially access your shared folders, smart cameras, and even connected printers. The solution? A Guest Network . The Xiaomi Mi Router AX1800 (often sold as the AX1800 or the "Global Version" of the Xiaomi router) is a powerful Wi-Fi 6 machine. However, creating a guest network on it isn't as straightforward as on a Netgear or Asus router—especially if you are using the Mi Wi-Fi app or the web interface. This guide will walk you through exactly how to create a guest network on the Xiaomi Mi Router AX1800 that works , troubleshoot common failures, and security tips to ensure your main network stays locked down. Why Your Xiaomi AX1800 Guest Network Might Not Be "Working" Before we dive into the steps, let's address the elephant in the room. Many users complain that after they create a guest network, it either:

Doesn't show up in the Wi-Fi list. Shows up but has no internet access. Connects to the internet but can still see their main network devices (defeating the purpose).

This usually happens because of software version discrepancies. Xiaomi uses two different firmware bases: Chinese ROM (often with English menus) and Global ROM . The steps differ slightly. We will cover both. Prerequisites: What You Need Before You Start To ensure this works perfectly, do the following:

Update your firmware: Go to Settings > System > Update in the Mi Wi-Fi app. The guest network feature was buggy in early 2021 releases but is stable now. Download the Mi Wi-Fi app: Version 5.6.0 or higher. Physical access: You need to be connected to the AX1800’s main network (either via 2.4GHz, 5GHz, or Ethernet cable). create guest network on xiaomi mi router ax1800 work

Method 1: The Mi Wi-Fi App (Recommended for 90% of Users) This is the easiest method for creating a guest network on the Xiaomi Mi Router AX1800. Step 1: Open the Mi Wi-Fi App Log in with your Mi Account. If you haven't bound the router to your account yet, do so by scanning the QR code on the bottom of the router. Step 2: Navigate to "Tools" At the bottom right of the screen, tap on the "Tools" tab (sometimes labeled "Settings" depending on the theme). Step 3: Find "Guest Wi-Fi" Scroll down until you see a section labeled "Guest Wi-Fi" or "Guest Network." Tap on it. If you don't see this option: Your router is in "Access Point (AP) mode" or "WISP mode." The guest network feature is disabled in these modes. Switch the router to "Wireless Router Mode." Step 4: Toggle it "On" At the top of the Guest Wi-Fi screen, you will see a master toggle switch. Flip it to ON . Step 5: Configure Your Guest Network (Crucial Settings) Now you will see several fields. Here is how to set them up so they actually work :

Wi-Fi Name (SSID): Choose something obvious like YourName_Guest or HouseGuest . Do not use special characters like & or # —the AX1800 struggles with these on guest networks. Encryption: Select WPA2-Personal (Do not use "Open" unless you want strangers stealing your bandwidth). Password: Create a simple password (e.g., visitortuesday ). Complexity is less important for guests than for your main network. Band: Choose 2.4GHz only .

Why? The AX1800 allows "2.4GHz & 5GHz" for guests, but many IoT devices (smart plugs, older phones) fail to connect to the dual-band guest network. For maximum compatibility, stick to 2.4GHz. How to Create a Guest Network on Xiaomi

Step 6: The "Working" Settings – Access & Permissions This is where most people mess up. You will see two checkboxes:

"Allow guests to see each other" : Check this if you have multiple guests who need to play LAN games or AirPlay to a guest speaker. Uncheck it for maximum privacy. "Allow guests to access my local network" : LEAVE THIS UNCHECKED.

This is the entire point of a guest network. If you check this, guests can see your PC, NAS, and printer. For a working secure guest network, ensure this box is empty . The solution

Step 7: Save & Reboot Tap the checkmark or Save in the top right corner. The router will apply the settings. Does it work now? Wait 60 seconds. Go to your phone’s Wi-Fi settings. The guest network SSID should appear. Connect using the password. You should have internet access, but you will not be able to ping your main network IPs. Method 2: The Web Interface (For Advanced Users) If the app fails, use a laptop and a web browser. Step 1: Log into the Router Open a browser and go to 192.168.31.1 (or miwifi.com ). Enter your admin password. Step 2: Go to "Advanced Settings" On the left sidebar, click "Advanced" or "Settings." Look for "Guest Network" (often nested under "Wi-Fi Settings"). Step 3: Manual Configuration The web interface offers more granular control.

Enable Guest Network: Check the box. Network Isolation: Ensure "AP Isolation" is turned ON . Band steering: Turn this OFF for the guest network to prevent connectivity drops.
