On the consequences of overheating broadband routers, Catherine Hiley, broadband expert at USwitch, told Express.co.uk: “We’re all struggling to keep cool in this heat wave, and electrical appliances like routers are no different. Just like laptops, phones and game consoles, routers need ventilation to remove excess heat. Therefore, they should not be placed in or near direct sunlight.
“A lot of us put them near windows because they are attached to cables that run through the outside walls. So if yours is overheating, try moving them further inside the property. Keep them in a shady spot and make sure the room is well ventilated. ” should be enough to avoid overheating; if you are using a fan to keep it cool, make sure the router is benefiting from the moving air as well.
“If your router regularly overheats, it may indicate that the device is having a problem or is getting too old to function properly. If this is the case, it may be worth asking your provider to send you a new router or to buy a compatible one through a trusted dealer. “
