Understanding Eufy Wi-Fi Requirements

Critical Eufy Wi-Fi Facts:

1. 2.4GHz ONLY: All Eufy RoboVacs use 2.4GHz Wi-Fi exclusively (NOT 5GHz)
2. During Setup: Your phone must ALSO be on 2.4GHz
3. After Setup: Phone can use 5GHz (RoboVac stays on 2.4GHz)
4. Router Distance: Must be within 30 feet during initial setup
5. Security: Supports WPA/WPA2 (NOT WPA3-only networks)

Why 2.4GHz? Better range through walls, lower power consumption, cheaper hardware. 5GHz offers faster speed but robot vacuums don't need high bandwidth.

Common Mistake: 90% of setup failures happen because phone is on 5GHz during setup. App can't find RoboVac because they're on different bands.

Try This First (3 Minutes)

Before detailed fixes, try these instant checks:

• ✅ Confirm 2.4GHz Wi-Fi (1 minute) - Check phone Wi-Fi settings, ensure connected to 2.4GHz network
• ✅ Restart RoboVac (1 minute) - Power switch off/on
• ✅ Move closer to router (30 seconds) - Place RoboVac within 10 feet of router during setup
• ✅ Restart app (30 seconds) - Force close EufyHome app, reopen

↳ Most Common Cause: Phone on 5GHz network during setup (42% of cases). App can't communicate with RoboVac on different band.

Fix 1: Ensure 2.4GHz Wi-Fi Connection (Works 42% of Time)

Why This First: Most connection failures trace to phone/RoboVac on different Wi-Fi bands.

Symptoms:

• Setup gets stuck at "Connecting to Wi-Fi"
• App says "Device not found"
• Setup worked before, stopped after router change
• You have dual-band router (2.4GHz + 5GHz)

How to Fix:

Step 1: Identify Your Wi-Fi Bands

Check Router Settings:

1. Log into Router: Browser → type router IP (usually 192.168.1.1 or 192.168.0.1)
2. Find Wi-Fi Settings: Look for "Wireless" or "Wi-Fi" section
3. Check Band Settings:
   • Single SSID (same name): Both bands use same network name (harder)
   • Separate SSIDs: 2.4GHz and 5GHz have different names (easier)

Separate Band Names (Recommended):

• Name 2.4GHz: "YourNetwork-2.4G"
• Name 5GHz: "YourNetwork-5G"
• Makes it obvious which band you're on

Step 2: Connect Phone to 2.4GHz

If Bands Have Different Names:

1. Open phone Wi-Fi settings
2. Select network with "2.4G" or "2.4GHz" in name
3. Connect to that network
4. Retry Eufy setup

If Bands Share Same Name:

1. Move Away from Router: Walk 30 feet away
2. Forget Wi-Fi Network: Phone settings → Forget network
3. Reconnect: Phone should prefer 2.4GHz at distance
4. Verify Band: Check Wi-Fi details (some phones show "2.4GHz" vs "5GHz")
5. Stay at Distance During Setup

iPhone Band Check:

• Settings → Wi-Fi → Tap (i) next to network name
• Doesn't always show band clearly
• Alternative: Use "Network Analyzer" app (free) to see band

Android Band Check:

• Settings → Wi-Fi → Tap network name → Advanced
• Shows "Frequency: 2.4 GHz" or "5 GHz"

Step 3: Retry Setup

1. Keep phone on 2.4GHz
2. Open EufyHome app
3. Add Device → Follow setup prompts
4. Should connect within 60 seconds

Time: 8 minutes
Cost: Free
Success Rate: 42%
Difficulty: Easy to Moderate

💡 Pro Tip: Temporarily disable 5GHz on router during Eufy setup for guaranteed 2.4GHz connection. Re-enable after.

Common Questions

How do I know if my router is 2.4GHz or 5GHz?

Check router label (usually on bottom). If says "Dual Band" or "AC1200+", has both 2.4GHz and 5GHz. Single band routers (older, N300) are 2.4GHz only. In router settings, wireless section shows bands.

Can I use Eufy with 5GHz-only mesh Wi-Fi systems?

No. If your mesh system only broadcasts 5GHz (like some Eero or Google Wi-Fi setups), Eufy won't connect. Check mesh app settings—most allow enabling 2.4GHz band. If not, need different router or manual control mode only.

My Eufy connected fine for 6 months, now suddenly offline - why?

Router firmware update may have changed settings (enabled AP isolation), or router itself glitched. Restart router first (unplug 30 seconds). If that fails, restart Eufy (power off/on). 95% of sudden disconnects fix with these two restarts.

Do I need Bluetooth on for Eufy setup?

Depends on model. Newer models (X9 Pro, X10 Pro, L70) use Bluetooth Low Energy during initial setup, then switch to Wi-Fi. Older models (11S Max, 15C, 30C) use Wi-Fi only. Enable Bluetooth during setup to be safe.

Can I control Eufy without Wi-Fi connection?

Yes. All models have AUTO button on top for manual start. Scheduled cleaning and app features require Wi-Fi. If Wi-Fi setup fails permanently, use manual mode or remote control (if included with your model).

Why does setup fail at 95% complete?

Router rejecting final connection handshake. Usually AP Isolation or MAC filtering. Check router for these settings. Also try temporarily disabling router firewall during setup (re-enable after).
