Xiaomi’s DHCP server is not responding: causes and fixes the error

Mistake «DHCP Server is not responding on Xiaomi devices is one of the most common network issues faced by users as smartphones (Redmi Note 12, POCO X5 Pro and routers (Mi Router) 4A, AX3600**). Translated into Russian, this means that your device cannot receive IP-address DHCP-server, a mechanism that automatically assigns network settings. IP Connection to the Internet or local network becomes impossible.

In 80 percent of cases, the problem is not with the Xiaomi device itself, but with the router, provider, or network conflict settings. But there are also specific MIUI or HyperOS firmware “jambs” that require special attention. In this article, we’ll look at all the possible causes, from a trivial failure to complex IPv6 conflicts, and give step-by-step instructions for each scenario. No water: only proven solutions that work on devices in 2020-2026.

1.Fast solution: reboot and reset the network

Start with the simplest thing: rebooting all devices in the connection chain, which helps in 30-40% of cases, especially if the error occurred after updating the firmware or changing the settings of the router.

How to properly reboot:

• 🔄 Router: Turn off power for 30 seconds, then turn it back on. Wait for full load (indicators should burn steadily).
• 📱 Xiaomi Smartphone/tablet: Press the power button, select Reboot. If the device is stuck, force it to turn off (clamp the power supply). + volume up 10 seconds).
• 💻 Computer/laptop (if connected to the same network): CMD: ipconfig /release && ipconfig /renew

If the reboot doesn’t help, reset the network settings on your Xiaomi device:

1. Go to Settings. → Wi-Fi.
2. Click on three dots in the top right → Additional → Reset your Wi-Fi, mobile internet and Bluetooth settings.
3. Confirm action. The device will restart.

⚠️ Warning: Reset will delete all stored Wi-Fi networks and passwords. Prepare the data in advance for reconnection.

2. Check router settings: DHCP, channels and IPv6

If the error appears on multiple devices at the same time, the problem is most likely in the router settings. Even the factory settings of the Mi Router or Redmi Router can get lost after firmware updates.

Inclusion DHCP-server

By default, DHCP on Xiaomi routers is turned on, but sometimes it shuts down after a crash or manual changes.

1. Go to the router’s web interface at 192.168.31.1 (or miwifi.com).
2. Go to Settings → Local Network → DHCP.
3. Make sure the switch is turned on DHCP-server active.
4. Check the range of IPs distributed: must be type 192.168.31.100-192.168.31.199.

2.2. IPv6 conflict

On Xiaomi routers with firmware 2023-2026, there is often a conflict between the two. IPv4 and IPv6, because of DHCP It stops responding. Try turning it off. IPv6:

1. In the router’s web interface, go to Settings → Internet.
2. Find the IPv6 partition and disable it.
3. Save the settings and restart the router.

2.3. Change of Wi-Fi channel

Congested channels (especially in apartment buildings) can cause delays in obtaining IP. In manual mode, select a channel with minimal interference:

• 📡 Use the WiFi Analyzer (Android) or NetSpot app (Windows/macOS) channel load analysis.
• 🔧 In the settings of the router (Wi-Fi) → Select the channel manually (e.g. 6 or 11 for 2.4 GHz).

Manual assignment IP-Addresses on Xiaomi device

If DHCP-The router server is working, but the Xiaomi device stubbornly does not receive IP, Try assigning a static address manually, and that's a temporary solution, but it can help you figure out exactly what the problem is.

Instructions for MIUI/HyperOS:

1. Go to Settings. → Wi-Fi.
2. Click on the name of your network → Change the network.
3. Enable the option to additional settings (or Show additional settings).
4. In the IP Settings section, select Static.
5. Fill in the fields: IP-address: 192.168.31.100 (if the router has a IP 192.168.31.1) Gateway: 192.168.31.1 Length of network prefix: 24 DNS 1: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)

Save and reconnect to the network.

If the internet is working, the problem is DHCP-If not, check the firewall settings or contact your provider.

⚠️ Attention: For manual assignment IP Make sure that the address selected (192.168.31.100) is not in the range DHCP-router pool (usually 192.168.31.100–192.168.31.199) Otherwise, conflict with other devices may occur.

💡

If the Internet is working after manual IP assignment, but the page miwifi.com does not open, try using the alternative router address: 192.168.31.1:8080 or http://192.168.31.1/cgi-bin/luci (for firmware based on OpenWRT).

4. Update of the router and smartphone firmware

Outdated software is a common cause of DHCP failures. Manufacturers regularly fix bugs in network stacks, so the update can solve the problem without additional action.

4.1. Update of Xiaomi router

For Mi Router/Redmi Router:

1. Connect to the router via cable or Wi-Fi.
2. Go to the web interface (miwifi.com).

For Redmi/POCO/Mi:

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If you have an update, download it and install it.

5.Problems on the provider side: blocking MAC-address

Some Internet providers (especially in Russia and the CIS) link access to the network to the Internet. MAC-If you change your router or reset your router, your provider can block new connections.

How to check and correct:

1. Find out. MAC-Router address: On the sticker below the router (field) MAC or WAN MAC). In the web interface: Settings → Status. → MAC-address WAN.

Contact the provider

Clone. MAC-address

1. In the router’s web interface, go to Settings → Internet.
2. Find the option to clone. MAC-address or use MAC-computer.
3. Save the settings and restart the router.

If the provider uses PPPoE or VPN (for example, L2TP), Make sure that the username / password is entered correctly in the router settings (Settings) → An authentication error can also block the delivery of IP.

💡

If the Internet does not work after changing the router, in 90% of cases the link is to blame MAC-ISP address, whether it's a call for support or a cloning MAC.

6.Reset router to factory settings

If no settings work, reset your router completely, and this will bring all settings back to factory settings, including DHCP, Wi-Fi, and ISP settings.

How to Reset Mi Router/Redmi Router:

2. Hardware reset (if web interface is not available): Press and hold the Reset button (usually located on the back) for 10-15 seconds. The indicators on the router should blink and go out - this is a signal of a successful reset.

After discharge:

• 🔧 Set up the router again (wi-fi name, password, type of connection to the provider).
• 🔄 Update the firmware to the latest version.
• 📱 Connect Xiaomi devices and check if the error has disappeared DHCP.

⚠️ Note: After reset, all user settings (including guest network, parental controls, and port forwarding) will be deleted.

7. Alternative solutions: from VPN to hardware replacement

If all the previous steps didn’t work, consider the less obvious causes and solutions:

• 🛡️ Turn it off. VPN Or proxy: Some of them. VPN-Services (e.g. NordVPN, ProtonVPN) are in conflict with DHCP. Turn them off in the smartphone settings (Settings) → VPN).
• 🔌 Check cables and ports: If the router is connected to the provider by cable, try replacing the patch cord or connecting to another port on the router.
• 📡 Use a different Wi-Fi range: Switch from 2.4 GHz to 5 GHz (or vice versa) in router settings.Some Xiaomi devices don't work well with encryption WPA3 — try WPA2.
• 🔄 Replace router: If an error appears on all devices and the router is older than 5 years, its network controller may have failed. AX6000, Redmi Router AX5400) lacking in this.

For advanced users:

• 🖥️ Check the router logs through SSH (If supported. Command: logread | grep dhcp Look for errors of type DHCPDISCOVER failed or no free leases.
• 🔧 Set up a backup. DHCP-server on another device (for example, on a Raspberry Pi with a Pi-hole).
