Somebody held up a phone with a Wi-Fi QR code on it, or taped one to a router, and your laptop has no obvious way to read the thing.
It does. The route is the Camera app rather than anything in the network settings, and there is one switch in it that nobody finds.
I read what this machine has for Wi-Fi before writing, and one of the readings is the reason a lot of home networks quietly stop sharing anything.
Microsoft's route, which is not where you would look
Start here, because Settings is a dead end for this.
⭐ Microsoft documents it on its connect to Wi-Fi page: "Open the Camera app. Select the barcode mode icon to switch from photo mode to barcode mode."
⚡ Barcode mode is the switch people miss. In photo mode the camera just takes a picture of the code.
⚠️ Then: "Point your device's camera at the QR code that contains the Wi-Fi connection information."
⛔ A link appears in the Camera app, and it opens Settings. You are not typing anything.
What happens after you scan it
Two steps, and the second is a choice worth reading.
⚡ Microsoft's wording: "In Settings, confirm that you want to add and connect to the Wi-Fi network."
⭐ You also decide whether it reconnects on its own: "You can choose if your device will connect automatically to that network when it is in range."
⚠️ Say no to that on a network you are visiting once. Say yes at home.
⛔ The password is never shown to you. It goes into the profile and stays there.
The requirement that stops most desktops
One line, and it is the whole answer for a lot of people.
⭐ Microsoft names it plainly: this route is for "Windows devices that have a camera".
⚡ A tower under a desk usually has none. No camera, no barcode mode, no scan.
⚠️ A plug-in webcam counts, and the Camera app will use it.
⛔ When I checked here, the machine had one wireless adapter and it was connected. A missing adapter is a different fault altogether.
Going the other way, which Windows barely does
This is the half people actually want, and it is thinner than you expect.
⚡ Your phone can show a QR code for the network it is on. Windows has no equivalent for a network it has merely joined.
⭐ Microsoft's mobile hotspot page does mention one, telling the other device to "enter the password or scan the QR code, and then connect".
⚠️ We could not find anywhere on that page that says where the code appears or whether Windows draws it at all. The sentence is there and the screen is not described.
⛔ So do not go hunting Settings for a share button. Windows will simply show you the password instead.
What this machine reports, and one number matters
Read rather than assumed, and the last one surprised me.
⭐ Ten saved Wi-Fi profiles here. Every network this laptop has ever joined keeps its own entry, silently, for years.
⚡ One wireless adapter, connected, with working internet. That is the ordinary state.
⚠️ The active network is set to Public. ⛔ I did not expect that on a home connection, and it is not a fault.
⛔ Public quietly turns off network discovery and file sharing. If a printer or another PC never appears, this is why.
Public or private, and why it matters here
Ours, and it is the practical half of scanning a code at somebody's house.
⚡ A network you joined by scanning a code lands wherever Windows puts it, and Public is the safe default.
⭐ Public is right on cafe and hotel Wi-Fi. It hides your machine from everything else on that network.
⚠️ Private is what you want at home, or your own printer and your other PC stay invisible.
⛔ It is one setting per network, in Wi-Fi properties. Moving files between two machines needs it too.
When the scan does not work
Four causes, cheapest first.
⭐ The Camera app is still in photo mode. Look for the barcode icon before anything else.
⚡ The code is not a Wi-Fi code at all. Plenty of printed codes are just a web address.
⚠️ The code is for a network that is not in range. Windows adds it and cannot connect until you are there.
⛔ Or the network has changed its password since the code was printed. Which kicks every device off at once.
Status: Wi-Fi state read on this laptop, 29 August 2026, Windows 11 Home 25H2 build 26200.9168, against Microsoft's own connect and hotspot pages. ⛔ No network name, password or profile name is published, no network was joined or left, and nothing was changed.
How do I scan a Wi-Fi QR code on Windows?
Open the Camera app, select the barcode mode icon to leave photo mode, and point it at the code. A link appears in the Camera app that opens Settings, where you confirm adding and connecting. Microsoft says this works on Windows devices that have a camera.
Can Windows generate a Wi-Fi QR code?
Not for a network it has simply joined. Microsoft's mobile hotspot page refers to another device scanning a QR code, but does not say where that code appears or whether Windows draws it. For an ordinary network, Windows shows you the password instead.
Why did my PC join the network but nothing else shows up?
Because the network profile is probably set to Public, which turns off network discovery and file sharing. This laptop reads Public on its own connection. Set a home network to Private in that network's Wi-Fi properties and your printer and other PCs reappear.
Do I need an app to scan a Wi-Fi QR code?
No. The Camera app that ships with Windows does it in barcode mode. The Microsoft Store carries several third party scanners, and none of them is needed for this.
The Short Version
- The route is the Camera app, not Settings, and barcode mode is the switch people miss.
- Microsoft says it works on Windows devices that have a camera. A desktop often has none.
- After scanning, Settings asks you to confirm, and offers automatic reconnection.
- Windows will not make a QR code for a network it has only joined.
- Microsoft's hotspot page mentions a code without saying where it appears.
- This laptop holds ten saved Wi-Fi profiles from networks going back years.
- Its active network reads Public, which switches off discovery and file sharing.
- Set a home network to Private or your own printer stays invisible.
Where to Next
Open the Camera app and find the barcode icon before you need it. Ten seconds now saves the fumbling later.
If you are on a desktop with no camera, ask for the password instead. There is no scan route for you.
Then check whether your home network reads Public or Private, because that one decides a lot.
Set home to Private and leave every cafe and hotel on Public.
And if you have found a Windows screen that does draw a Wi-Fi QR code, tell me where it is in the comments. I could not find one.
