How to Fix a Router That Feels Hot and Drops Connections
Your router is uncomfortably hot to the touch and keeps dropping Wi-Fi connections - here's how to cool it down and restore stability.
What's Happening
Your router feels hot enough to fry an egg, and your internet keeps cutting out at the worst possible times. This is one of the most common hardware issues with routers, especially in warm climates or enclosed spaces. The good news? Most overheating problems can be fixed without buying new equipment.
Quick Checks (Do These First)
- Feel the router. If it's too hot to comfortably touch for more than 3 seconds, it's overheating.
- Check the location. Is it in a cabinet, on carpet, or stacked with other electronics?
- Look at the vents. Are they dusty or blocked?
- Count the devices. Do you have more than 15 devices connected simultaneously?
- Check the power adapter. Is it also hot or making any noise?
Step-by-Step Fixes
Fix 1: Improve Airflow Around Your Router
- Unplug your router and let it cool for 10-15 minutes
- Move it to an open location - on top of a desk or shelf, not inside furniture
- Make sure there's at least 4-6 inches of space on all sides
- Keep it away from heat sources like game consoles, cable boxes, or windows with direct sunlight
- Position it vertically if it has a stand - this helps heat rise naturally
- Plug it back in and monitor the temperature over the next hour
Fix 2: Clean the Vents and Interior
- Unplug the router completely
- Use compressed air to blow dust out of all vents (hold the can upright)
- If you're comfortable opening it, remove screws and gently clean inside with compressed air
- Check for dust buildup on circuit boards and cooling components
- Reassemble and place in a well-ventilated spot
Note: Opening your router may void the warranty. If it's still under warranty, skip this step.
Fix 3: Add External Cooling
- Get a small USB-powered fan or laptop cooling pad
- Position it to blow air across the router's vents
- Alternatively, use a small desktop fan pointed at the router
- Monitor if connection drops decrease over the next 24 hours
You can find small USB fans for under $10 that run silently and make a huge difference.
Fix 4: Reduce the Load on Your Router
- Access your router's admin panel (usually at 192.168.1.1 or 192.168.0.1)
- Look for a device list or connected clients section
- Disconnect devices you're not actively using
- Consider using wired Ethernet for stationary devices like game consoles and smart TVs
- This reduces the wireless workload and heat generation
If Nothing Worked
If your router still overheats after improving ventilation and cleaning, the internal components may be failing. Check if your router is several years old - older models run hotter than modern designs. You might also have a faulty power adapter delivering incorrect voltage, which causes excess heat. Try borrowing a compatible power adapter to test if that's the issue.
When to Call a Pro
If your router continues overheating despite all these fixes, or if you notice a burning smell, stop using it immediately. Overheating routers can be a fire hazard. If you're not comfortable opening electronics or need help setting up a replacement, professional help can save you time and frustration.
