Why Won't My Laptop Connect to Wi-Fi? 9 Fixes That Work

There's nothing more frustrating than sitting down to work, stream or game and finding your laptop simply won't connect to Wi-Fi. Your phone connects fine, everyone else in the house is online, but your laptop (or PC) just sits there spinning or showing "no internet access" or "can't connect to this network". Don't worry — this happens to almost everyone at some point, and in most cases it's a quick fix.

Below we've listed the most common reasons your laptop won't connect to Wi-Fi, followed by 9 fixes ranging from the blindingly obvious to the more technical, plus a reliable backup option if you need to get online right now.

Before jumping into fixes, it helps to know what's usually causing the problem. The most common culprits are:

• Wi-Fi is switched off — either in Windows/macOS settings or via a physical switch or function key on the laptop itself
• Airplane mode is enabled, which disables all wireless connections
• Incorrect Wi-Fi password entered, especially after a router reset
• Outdated or corrupted network drivers
• Router or ISP issues, including outages or the router needing a restart
• Weak signal due to distance from the router or interference from walls and other devices
• Incorrect network settings, such as a bad IP configuration
• A faulty Wi-Fi adapter inside the laptop itself

Work through the fixes below in order — they're arranged from quickest to most involved, so you'll usually solve the problem long before you reach the end of the list.

It sounds basic, but it's worth checking first. Many laptops have a physical Wi-Fi switch or a function key (often Fn + F2 or similar) that toggles wireless on and off. Check your Windows or macOS network settings too — it's easy to knock it off by accident.

If Airplane Mode is enabled, your laptop won't be able to connect to any wireless network. Check the Wi-Fi icon in your taskbar or menu bar and make sure it's switched off.

The classic "turn it off and on again" fixes a huge number of connectivity issues. Restart your laptop, unplug your router for 30 seconds, then plug it back in and give it a minute or two to reconnect fully.

Go into your Wi-Fi settings, select your network, choose "Forget" (Windows) or "Remove Network" (macOS), then reconnect from scratch and re-enter your password. This clears out any corrupted connection data that might be causing the issue.

Thick walls, floors and even large appliances can weaken a Wi-Fi signal. If you're working from another room, try moving closer to the router to rule out signal strength as the problem.

Both Windows and macOS have built-in diagnostic tools that can automatically detect and fix common network problems. On Windows, search for "Network Troubleshooter" in the Start menu. On a Mac, hold Option and click the Wi-Fi icon for diagnostics.

Outdated Wi-Fi drivers are a common cause of intermittent or failed connections. On Windows, open Device Manager, expand "Network adapters", right-click your Wi-Fi adapter and select "Update driver". On a Mac, driver updates are handled through regular macOS software updates.

If nothing else has worked, a full network reset can clear out deeper configuration issues. On Windows, go to Settings > Network & Internet > Advanced network settings > Network reset. Note that this will remove any saved Wi-Fi passwords, so make sure you have them to hand.

If every device in the house is struggling, the problem may not be your laptop at all. Check your provider's outage map or contact them directly — it may simply be a case of waiting it out.

If you've worked through the list above and you're still not online — or you just need a guaranteed, stable connection right now for an important call or a large file transfer — the simplest fix is to bypass Wi-Fi completely and plug in.

Most modern laptops, ultrabooks and MacBooks don't have a built-in Ethernet port, so you'll need a small adapter to bridge USB-C to a standard network cable. This is genuinely one of the most useful bits of kit to keep in a laptop bag: it takes Wi-Fi troubleshooting out of the equation entirely, and a wired connection is typically faster and more stable than wireless anyway.

The Nikkai USB-C to Gigabit Ethernet Adapter plugs straight into any USB-C port and gives you a Gigabit RJ45 Ethernet connection, no drivers or setup required — just plug it in, connect an Ethernet cable to your router, and you're online. At 0.25m and pocket-sized, it's small enough to leave in your bag permanently as a backup.

If you'd rather have everything in one lead with nothing to lose, the Maplin USB-C to RJ45 Ethernet Cable combines the adapter and cable into a single unit — handy for a permanent desk setup.

And if you regularly connect your laptop to a monitor, keyboard and other peripherals, it's worth stepping up to a full docking hub rather than a single-purpose adapter. The Nikkai USB-C Multiport Hub adds Gigabit Ethernet alongside HDMI, VGA, three USB-A ports, an SD/microSD card reader and USB-C power delivery — effectively turning any USB-C laptop into a fully wired desktop setup in one connection.

Don't forget you'll also need an Ethernet cable to run from the adapter to your router — our CAT7 Flat Ethernet Cable is a slimline option that's easy to run under carpets or along skirting boards if you're setting up a permanent connection.
