Brits warned heatwave could BREAK their Wi-Fi – three ways to ensure your route keeps running

In order for your WiFi router to work properly, it is important to keep it in a cool place.

With a heatwave sweeping across the UK this week, your WiFi could go down if it gets too hot.

Catherine Hiley, telecoms expert at, shared three key tips for keeping your router cool.

Avoid hotspots

If your router is on or near the window sill, you may want to move it to a different location.

Direct exposure to sunlight is not ideal at all.

The best room is in a central location where there are fewer windows and it’s cooler.

Not only are windows bad for exposing your box to sunlight, they also send signals out to nowhere.


WiFi routers need space to ventilate.

Place it on a firm, level surface – and not close to other objects.

“Routers have built-in fans to help cool them down,” explains Catherine.

“That means they need space around them to vent the hot air created by all the processing they have to do.”

“If your router is surrounded by a lot of other objects, it won’t be able to ventilate properly and could overheat.”

Disconnect obsolete devices from the power supply

The more devices trying to connect to your router, the harder it has to function.

Turning off WiFi on devices you’re not using can help relieve stress during hot times.

“The more devices you have connected to your router, the more difficult it must be to keep them all online, increasing the likelihood of slowdowns or shutdowns,” explains Catherine.
