Let's get your Xiaomi connected reliably to Wi-Fi.
Try This First (3 Minutes)
Before detailed troubleshooting, try these quick checks:
- ✅ Verify 2.4GHz Wi-Fi (1 minute) - Xiaomi ONLY connects to 2.4GHz, not 5GHz
- ✅ Reset Wi-Fi on robot (30 seconds) - Hold Wi-Fi button 3-6 seconds until voice prompt
- ✅ Restart router (2 minutes) - Full power cycle of Wi-Fi router
- ✅ Check robot placement (30 seconds) - Place robot within 3 meters of router during setup
↳ Most Common Cause: Attempting to connect to 5GHz Wi-Fi network instead of required 2.4GHz (43% of Xiaomi connection failures).
Fix 1: Ensure 2.4GHz Wi-Fi Network (Works 43% of Time)
Why This First: Xiaomi Mi Robot vacuums use 2.4GHz Wi-Fi ONLY. Cannot connect to 5GHz networks. Most modern routers broadcast both frequencies, causing confusion.
Symptoms:
- Setup fails during Wi-Fi connection step
- App shows "Cannot find robot" or "Connection failed"
- Recently upgraded router or changed Wi-Fi settings
- Works at friend's house but not yours
How to Fix:
Step 1 - Check Your Network Frequency:
On Smartphone:
- Open Wi-Fi settings
- Look at connected network name
- Common patterns:
- "YourNetwork" = Usually 2.4GHz
- "YourNetwork-5G" or "YourNetwork_5GHz" = 5GHz (won't work)
- Check in advanced Wi-Fi details for frequency
On Router:
- Log into router admin panel (usually 192.168.1.1 or 192.168.0.1)
- Navigate to Wi-Fi/Wireless settings
- Find frequency band settings
- Should show both 2.4GHz and 5GHz networks
Step 2 - Configure Router for Best Compatibility:
Option A - Separate Network Names (Recommended):
- Log into router settings
- Find 2.4GHz network settings
- Rename 2.4GHz network distinctly (e.g., "MyHome-2.4G")
- Leave 5GHz network with different name (e.g., "MyHome-5G")
- This prevents accidental 5GHz connection attempts
Option B - Temporarily Disable 5GHz:
- Router settings → Wireless
- Temporarily disable 5GHz band
- Connect Xiaomi robot to 2.4GHz
- Re-enable 5GHz after robot connected
- Robot will stay on 2.4GHz
Step 3 - Connect Phone to 2.4GHz Network:
- Critical: Your smartphone MUST be on same 2.4GHz network during setup
- Disconnect from 5GHz network
- Connect to 2.4GHz network
- Verify in Wi-Fi settings before proceeding
Step 4 - Restart Setup:
- Open Mi Home app
- Remove Xiaomi robot from app (if previously added)
- Reset robot Wi-Fi (hold Wi-Fi button 3-6 seconds)
- Add device again → Robot Vacuum → Select your model
- Follow prompts - should connect successfully now
Time: 10-15 minutes
Cost: Free
Success Rate: 43%
Difficulty: Easy to moderate
💡 Pro Tip: After successful connection, you can switch your phone back to 5GHz. Robot stays on 2.4GHz independently.
If This Doesn't Work: Try Fix 2 - router compatibility settings
