Windows can't find Wi-Fi networks
The Wi-Fi control exists, but Windows shows no available networks. Check the radio and band compatibility; use the missing Wi-Fi option guide if the control or adapter is absent.

Diagnostic signals
- ObservationOnly one network is missing
- Compare its band with the adapter specifications. Other visible networks change the diagnosis from a completely empty list.
Step-by-step solutions
Check that the radio is on
A visible control may still be switched off.
Enable Wi-Fi in Settings > Network & internet. Check the physical wireless switch if present.
Reopen the network list near the router.
Compare supported bands
Not every adapter can discover every network.
Check the router manual or settings for its broadcast band and the adapter specifications for supported bands.
If your router offers a network on a compatible band, check whether it appears. Get authorization before changing a shared network.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Review the adapter mode
Check band filtering before reinstalling anything.
In Device Manager, open the wireless network adapter properties.
If Advanced offers Band or Wireless Mode, compare it with the manufacturer documentation. Record the original value before correcting a restriction; skip this step if the setting is absent.
Still not working?
If the list stays empty near a compatible network another PC can detect, give the manufacturer the adapter model and driver version. Switch to the missing-control diagnosis if Wi-Fi itself disappears.

Wi-Fi option missing in Windows
Windows does not show the option to enable Wi-Fi. First check whether the wireless adapter is present and enabled. Restarting the router alone does not restore an adapter Windows cannot detect.
View solutionWi-Fi connected but no internet
Joining Wi-Fi does not guarantee internet access. Compare another device on the same network to separate a PC-specific problem from a local-network or provider-side issue.
View solutionInternet keeps disconnecting
Connectivity works, then drops again. Record which devices and connection types fail together; that pattern is more useful than repeatedly resetting the network.
