my q7 max plus won't connect to wifi during setup, the app just times out.

Diagnosis

The Roborock Q7 Max Plus utilizes a network interface card that is strictly compatible with 2.4 GHz frequencies. When the Roborock app times out during the "Connecting to Robot" or "Connecting to Network" phase, it is typically because the robot is unable to complete the TCP/IP handshake with your router. This happens most frequently in modern "Mesh" or "Smart Connect" environments where the router dynamically assigns the device to a 5 GHz band, or where the 2.4 GHz and 5 GHz bands share the exact same SSID (Network Name). The robot cannot distinguish between the two and fails to authenticate, leading to the app timeout error. Additionally, the Q7 Max Plus is sensitive to specific encryption protocols. If your router is set to WPA3 or a "Mixed Mode" (WPA2/WPA3), the robot's firmware may struggle to negotiate the security key, causing the connection to hang. You can confirm this is a network issue if the robot's voice prompt says "Connecting to Wi-Fi" for several minutes before eventually announcing "Connection failed," while your smartphone remains connected to the internet.

How to Fix It

To resolve the connection timeout, follow these precise configuration steps:

1. Isolate the 2.4 GHz Band: Access your router's admin panel via your web browser. Navigate to Wireless Settings and disable "Smart Connect" or "Band Steering." Create a separate SSID specifically for 2.4 GHz devices (e.g., "HomeWiFi_2.4").
2. Adjust Security Settings: In the router security tab, change the authentication mode from WPA3 or Mixed Mode to WPA2-PSK (AES). This is the most stable protocol for the Q7 Max Plus hardware.
3. Reset Robot Network: Press and hold the "Spot Clean" and "Dock" buttons simultaneously for 3 seconds until the robot announces "Resetting Wi-Fi." This clears any cached failed attempts.
4. Optimize Proximity: Move the charging dock and the robot to the same room as your router, ideally within 10 feet (3 meters) of the broadcasting antenna. This eliminates signal interference during the initial handshake.
5. Phone Configuration: Ensure your smartphone is connected to the newly created 2.4 GHz SSID. Disable "Mobile Data" in your phone settings temporarily to force the app to communicate exclusively via the local Wi-Fi network.
6. Re-run Setup: Open the Roborock app, select "Add Device," and follow the prompts. When prompted for the password, double-check for special characters; avoid using symbols like '&' or '%' in your Wi-Fi password as they can occasionally cause timeout errors on this specific model.

If That Didn't Work

• DNS Override: If the robot connects but the app still times out, change your router's DNS settings to Google's Public DNS (Primary: 8.8.8.8, Secondary: 8.8.4.4). Some ISP-provided DNS servers block the specific ports used by Roborock's cloud servers.
• Firewall Port Check: Ensure that your router's firewall is not blocking Port 80, 443, or 8080. If you have a sophisticated firewall (like pfSense or Ubiquiti), create a DHCP reservation for the robot and allow all outbound traffic for that specific MAC address.
• The Hotspot Test: To determine if the robot's Wi-Fi chip is defective, use a second smartphone to create a 2.4 GHz mobile hotspot. Attempt to connect the Q7 Max Plus to this hotspot using your primary phone. If it connects instantly, the issue is definitively your router's configuration or hardware compatibility.
• Region Mismatch: Verify that your Roborock app region matches the hardware version of your robot. If you bought a Chinese-market (CN) version of the Q7 Max Plus but set your app region to "United States," the connection will time out during the server authentication phase.

Heads Up

• Avoid Special Characters: Keep your Wi-Fi SSID and password alphanumeric. Symbols in the network name can cause the Q7 Max Plus to fail the handshake process.
• Firmware Updates: Once connected, immediately check for firmware updates in the app. Roborock frequently releases patches that improve Wi-Fi stability and connectivity for newer router standards.
• DHCP Lease: If you have a very high number of smart devices (50+), your router may be out of IP addresses. Assign a static IP to the robot via its MAC address in your router settings to prevent future disconnects.
