Wi-Fi problems are usually fixable — no new router required

Most home Wi-Fi trouble comes from a handful of causes: a router in the wrong spot, crowded channels, dead zones solved the wrong way, or a speed problem that was never the Wi-Fi at all. These guides walk through each one in plain language, starting with the free fixes.

Start where most problems actually are

Before spending a dollar, check the order things usually go wrong: the router's position, the channels it's using, and whether your internet connection itself is the bottleneck. Only when those are sorted does new hardware make sense — and then the choice between mesh, extenders, and access points matters more than the brand on the box.
