Connection Stability Tester
Free Online Controller Connection & Signal Test Tool
Test your gamepad's connection stability, signal strength, and detect disconnection issues. Monitor real-time connection quality for PS5, PS4, Xbox, Switch Pro, and PC controllers. No download required.
Connection Stability Test
Monitor your controller's connection quality in real-time
Connection Stability Monitor
How it works: This tool continuously monitors your controller's connection status, tracking disconnections, signal drops, and input responsiveness over time.
Start the test and use your controller normally. The tool will detect any connection instability, dropouts, or lag spikes during the monitoring period.

Analyze the stability rating, disconnection events, and timeline to identify connection issues.
Understanding Connection Stability
Learn about what affects your controller's connection reliability
Wireless Interference
Wireless controllers can experience interference from other devices operating on similar frequencies, causing connection drops.
- WiFi routers (2.4GHz band)
- Other Bluetooth devices
- Microwave ovens
- Cordless phones
Power & Battery Issues
Low battery or insufficient USB power can cause intermittent disconnections and unstable connections.
- Battery below 20% threshold
- USB hub power limitations
- Faulty charging cables
- Damaged battery cells
Hardware & Software Factors
Driver issues, firmware bugs, and hardware defects can all contribute to connection instability.
- Outdated controller firmware
- Driver conflicts
- Worn USB ports
- Damaged Bluetooth antenna
Tips for Improving Connection Stability
Optimize your setup for the most reliable controller connection
Use Quality USB Cables
Use the original cable or a high-quality replacement. Cheap cables often cause intermittent connections.
Reduce Distance
Keep wireless controllers within 10 feet of the receiver. Walls and obstacles weaken signals.
Minimize Interference
Move away from WiFi routers and other 2.4GHz devices. Use 5GHz WiFi when possible.
Update Firmware
Keep your controller firmware updated. Manufacturers often fix connectivity bugs in updates.
Maintain Battery
Keep battery above 30% for optimal wireless performance. Replace rechargeable batteries every 2-3 years.
Direct USB Connection
Connect directly to motherboard USB ports, not front panel or hub ports, for best stability.
Troubleshooting Connection Issues
Common problems and solutions for unstable controller connections
Random Disconnections
Possible Causes:
- Low battery or power issues
- USB power saving enabled
- Wireless interference
- Driver conflicts
Solutions:
- Charge controller fully before testing
- Disable USB selective suspend in Windows
- Move away from other wireless devices
- Reinstall controller drivers
Won't Stay Connected
Possible Causes:
- Pairing issues with Bluetooth
- Damaged USB port or cable
- Controller needs reset
- Conflicting Bluetooth devices
Solutions:
- Remove and re-pair the controller
- Try different USB port or cable
- Reset controller to factory settings
- Disconnect other Bluetooth devices
Weak/Unstable Signal
Possible Causes:
- Distance too far from receiver
- Physical obstructions
- Damaged wireless antenna
- Low quality Bluetooth adapter
Solutions:
- Move closer to the receiver/console
- Remove obstacles between controller and receiver
- Try a USB Bluetooth adapter extension
- Upgrade to a better Bluetooth adapter
Intermittent Lag Spikes
Possible Causes:
- System resource constraints
- Background applications
- USB bandwidth saturation
- Driver polling issues
Solutions:
- Close unnecessary background apps
- Connect to USB 3.0 port
- Update USB host controller drivers
- Check for system thermal throttling
Frequently Asked Questions
Common questions about controller connection stability
What causes controller disconnections during gaming?
+Controller disconnections can be caused by wireless interference, low battery, USB power saving settings, driver issues, or physical damage to cables/ports. Wireless controllers are more susceptible to interference from WiFi, Bluetooth devices, and even microwave ovens. For wired controllers, faulty cables or loose USB connections are common culprits.
Is wired or wireless more stable?
+Wired connections are generally more stable than wireless. USB provides consistent power and eliminates wireless interference issues. However, modern wireless technologies like Xbox Wireless Adapter and PlayStation's proprietary wireless offer excellent stability when properly configured. Bluetooth tends to be less stable than dedicated wireless protocols.
How do I fix USB power saving disconnections?
+In Windows, open Device Manager, find your USB Root Hubs under "Universal Serial Bus controllers", right-click each one, go to Properties, Power Management tab, and uncheck "Allow the computer to turn off this device to save power". Also disable USB selective suspend in Power Options under USB settings.
Why does my controller disconnect when I use it?
+If your controller disconnects specifically during use, it may be due to a loose cable connection, a faulty cable that disconnects with movement, or a damaged USB port. For wireless, rapid button presses or stick movements can sometimes overload poor Bluetooth connections. Try a different cable, port, or reduce distance to the receiver.
What polling rate should I use for this test?
+For most testing, 125Hz (8ms) provides a good balance between detection accuracy and system load. Use higher rates (250Hz/500Hz) if you're testing a controller that supports high polling rates and want to detect very brief dropouts. Lower rates (60Hz) are sufficient for basic stability testing and use fewer system resources.
Can a bad cable cause stability issues?
+Absolutely. Damaged, low-quality, or charge-only cables are a leading cause of connection instability. Internal wire breaks can cause intermittent connections, especially when the cable moves. Always use data-capable cables (not charge-only), preferably the original cable or a high-quality replacement. If stability improves with a different cable, the original was likely faulty.
