Before filing another complaint with your broadband provider, consider the clutter on your desk. Many wireless peripherals—dongles, hubs, cordless phones, even microwaves—operate on the 2.4GHz frequency, the same band many Wi-Fi networks rely on. With offices packed full of these devices, signals crowd each other out, slowing connections even when the router itself is fine.
USB 3.0 adds another layer of trouble. High-speed data transfer through USB 3.0 generates electromagnetic radiation in the 2.4GHz to 2.5GHz range, which can directly interfere with nearby Wi-Fi. The article suggests using extension cables to move USB dongles farther from ports, and physically separating devices to give radio waves more room.
A practical fix is to prune unnecessary connected gadgets and reboot the router. Rebooting clears the router's cache and forces it to pick a less noisy channel. For businesses, this low-cost housekeeping can improve network performance without upgrading equipment or calling in specialists.
