UPDATE: Experts are sounding the alarm over the dangers of connecting certain devices to your Wi-Fi router’s USB port. With the rise of versatile modern routers, many users may be tempted to plug in their gadgets, but this could lead to serious risks.
Many routers now come equipped with USB ports marketed for convenience. However, not all devices are safe to connect. Plugging in the wrong hardware can result in network slowdowns, security breaches, or even permanent damage to your router.
Authorities warn that charging smartphones directly from a router is particularly risky. While it may be technically possible with some routers, the limited power output—often between 2.5 to 4.5 watts—means most devices won’t charge effectively. For example, an iPhone 17 Pro Max may charge slowly or not at all, leading to overheating issues that can shorten the router’s lifespan.
Instead of relying on your router for charging, experts recommend investing in a dedicated charging hub, such as the Anker 122W Max 6-Port Charging Station, available for around $15 to $40. This ensures devices receive the proper power without risking your router’s health.
Additionally, while connecting external hard drives to create a network-attached storage (NAS) solution seems convenient, it can pose significant risks. Not all routers have the capability to handle large storage devices reliably. Many routers still operate on USB 2.0, which results in slow data transfer speeds. Drives over 8TB may fail to run or disconnect randomly, leading to frustrating data access issues.
Security concerns also arise when using USB ports. Cybersecurity experts emphasize that untrusted USB devices can introduce malware into your network. Hackers often exploit these ports as entry points for cyber attacks, potentially allowing unauthorized access to personal files or even overwriting router firmware.
To protect against these threats, users are advised to only use trusted devices and regularly update router firmware. Enabling WPA2 or WPA3 encryption and using guest networks further enhances your security.
In summary, connecting your smartphone, a large external hard drive, or any untrusted USB device to your router’s USB port poses serious risks that could compromise your entire network. Stay informed and safeguard your home internet setup by following these expert recommendations.
