Most Wi-Fi problems show a network that won’t connect. This one is different: your Chromebook doesn’t see any networks at all, not even ones sitting right next to the router. That points to the Wi-Fi radio itself, not a single bad connection.
Quick answer: First confirm Wi-Fi is actually turned on and the toggle isn’t stuck. If it is on and still nothing appears, reboot, then try Settings > Reset network settings. If a completely fresh scan still shows zero networks on a device that used to work fine, the internal Wi-Fi card or antenna cable is the likely culprit and the Chromebook needs a hardware inspection.
Why Would a Chromebook See No Networks At All?
- Wi-Fi is toggled off, or ChromeOS has it disabled after an update or a Powerwash
- Airplane mode got turned on by accident, which disables Wi-Fi along with Bluetooth and mobile data
- A software crash in the network stack after a botched update, which usually clears with a restart
- A loose internal antenna cable or Wi-Fi card, common after a drop, a repair, or a fall
- A dead Wi-Fi module, which is rare but does happen on older devices
If your Chromebook sees networks but just won’t join yours specifically, that’s a different problem — see the general Wi-Fi connection guide instead.
How to Fix a Chromebook That Shows No Wireless Networks
- Click the status area (bottom-right clock) and confirm the Wi-Fi icon is on, not grayed out. Also check that airplane mode is off.
- Restart the Chromebook completely — press and hold
Power, then select Restart. Many “no networks” cases are a stuck network stack that a full reboot clears. - Go to
Settings>Network> Reset network settings, confirm, then restart again. This clears corrupted Wi-Fi state that can suppress scan results — full steps in how to reset network settings on a Chromebook. - Test whether other devices near the same router see it. If phones and laptops also can’t see it, the problem is the router, not your Chromebook.
- Open the Diagnostics app (
Launcher> search “Diagnostics”) and run the network test to see if ChromeOS reports the Wi-Fi hardware as present at all. - If a recent drop, spill, or repair lines up with when networks stopped appearing, suspect a loose antenna connector or Wi-Fi card rather than a settings issue.
Still No Networks Showing Up?
If a reset and reboot don’t bring back a single network, and the Diagnostics app shows the Wi-Fi hardware as missing or failing:
- Check whether the issue started right after opening the case for a repair — see how to open a Chromebook for how the antenna cables typically route near the hinge
- Try a USB-C to Ethernet adapter as a workaround while you sort out the Wi-Fi hardware — see how to use a USB-C to Ethernet adapter on a Chromebook
- Check your Chromebook’s AUE date before paying for a hardware repair on an older device
- A dead internal Wi-Fi card typically needs a repair shop, since it involves opening the case and reseating or replacing an internal component
FAQ
Why does my Chromebook see other networks but not mine?
That’s a router-specific or band-specific issue, not a dead adapter — see Chromebook can’t find 5GHz Wi-Fi for the most common cause.
Can a ChromeOS update break the Wi-Fi adapter?
It can cause a software-level glitch that hides all networks, but this is almost always fixed by a restart or a network settings reset, not a sign of failed hardware.
How do I know if it’s the router and not the Chromebook?
Check whether a phone or another laptop sitting next to the router also fails to see it. If every device is blind to the network, the router is the problem, not your Chromebook.
