Wi-Fi slow? Test your speed, try quick router fixes, switch to 5 GHz, tune adapter and power settings, change DNS and stop bandwidth-hungry downloads.

Not sure this is your exact issue? Every WindowsHelper guide is scoped to one specific problem — not a generic troubleshooting checklist — so if the title above matches what you're seeing, this is the right guide.

What 'slow Wi-Fi speed' actually measures

Your Wi-Fi connection has a negotiated link speed — how fast your PC and your router are actually talking to each other — separate from your internet plan's speed and separate from whether the connection stays up at all. Slow Wi-Fi speed means that link itself is running well below what it should, even though you're connected, staying connected, and have internet access.

This is different from Wi-Fi that drops or won't connect, and different from general browsing slowness that can happen even over a wired connection — this is specifically about the wireless link's own speed being weaker than it should be, which is its own narrower thing to pin down.

How to tell it's the Wi-Fi link speed, not something else

How serious is it?

Usually minor

Some speed drop-off with distance from the router is normal for any Wi-Fi connection — that's simply how wireless signal behaves.

Worth taking seriously

A large, consistent gap between this PC's Wi-Fi speed and what other devices get on the same network, even nearby, is worth understanding rather than assuming it's just distance.

Why moving closer to the router isn't always the fix

Distance is the obvious first thing to blame, and it genuinely matters — but a weak link speed can also come from how the PC's adapter negotiated the connection, interference, or the network itself, and none of those improve just by standing closer if they're the real cause.

Figuring out how much of your specific slowdown is distance, and how much is something else entirely, is what WindowsHelper is being built to help work out rather than assuming it's always about the router.

Common questions

Is this the same as my internet being slow?
Not quite — this is about the wireless link's own speed specifically, which is a different measurement from your overall internet plan's speed, though a weak link can drag your effective speed down too.
Why is my phone faster than my PC on the same Wi-Fi?
That's a useful clue — it points toward something specific to this PC's connection to the network, rather than the Wi-Fi network or your internet plan being the limit.
Will a Wi-Fi extender fix it?
It can help if distance and signal strength are genuinely the cause, but if the real limit is something else about the connection, an extender won't necessarily move the needle.
Does the speed I'm paying for match what Wi-Fi can deliver?
Not always directly — Wi-Fi has its own speed ceiling separate from your internet plan, so even a fast plan can be capped by a weaker wireless link.
