Create Guest Network On Xiaomi Mi Router Ax1800 Fixed ((top)) [ORIGINAL]
Setting up a guest network on your Xiaomi Mi Router AX1800 is a great way to let visitors hop on your Wi-Fi without giving them full access to your personal devices and home network
Summary
- Use the App: The easiest way to create a guest network is via the Mi Wi-Fi app under "Network Settings."
- Check Mode: If the option is missing, ensure the router is in Router Mode, not Access Point Mode.
- Update Firmware: Missing UI elements are often fixed by updating to the latest stable firmware.
- Manual Security: If you have to create a manual SSID, ensure you manually configure firewall rules to isolate guests from your main devices.
| Issue | Symptom | Root Cause | Fixed Solution |
|-------|---------|------------|--------------------|
| No IP assigned | Devices stuck on “Obtaining IP address” | DHCP server for guest network crashes or conflicts with main DHCP range. | Static IP Range: Set Guest DHCP range outside main pool.
Main: 192.168.31.100–200
Guest: 192.168.33.50–150 (different subnet) |
| Guest sees main LAN devices | Security breach | AP isolation disabled or incorrect VLAN tagging. | Enable AP Isolation: In Guest Wi-Fi settings, check “Allow guests to access each other” → NO.
“Allow guests to access local network” → NO. |
| Slow / intermittent speed | High latency, packet loss | Co-channel interference with main 2.4 GHz network. | Fixed Channel: Set main Wi-Fi to channel 1,6,11 (e.g., ch6). Set Guest Wi-Fi to same channel (AX1800 forces same radio). Reduce beacon interval to 100ms. |
| Clients disconnect every 30 min | Logout loop | Default DHCP lease time too short (2 hours). | Increase Lease Time: Via SSH or config file → Set dhcp_lease_time=86400 (24 hours). Not exposed in GUI – requires advanced access. |
| No internet for guests | DNS failure | Router’s DNS proxy doesn’t forward guest subnet. | Manual DNS: In Guest settings, set Primary DNS 8.8.8.8, Secondary 1.1.1.1. Disable “Use same DNS as main network”. | create guest network on xiaomi mi router ax1800 fixed
