Wi-Fi & Internet Problems
Wi-Fi that won't connect, drops out, or works everywhere except one computer — what's usually behind it and what's worth checking first.
Wi-Fi and internet problems are often blamed on the router when the actual fault is somewhere else entirely — a specific computer's network adapter, a driver that needs updating, or an internet plan issue that has nothing to do with Wi-Fi at all. The first useful step is usually working out how widespread the problem is: does it affect every device, or just one computer? Is it a connection problem or a speed problem? The guides below cover the most common patterns, from a computer that won't connect at all through to internet that's technically connected but not actually working.
