WIFI Stopped Working on Windows 7?
If you have a wireless adaptor that used to connect to a Wifi network and is unable to then your WLAN adaptor is likely disabled. To further verify this, when you go to Control Panel > Network and Internet > Network Connections, your wifi adaptor is greyed out indicating it’s disabled and right-clicking on it, choosing “Enable” does not resolve.
Fix / enable your network adaptor again on Windows 7
- Start > Run > type services.msc (enter)
- Scroll down to WLAN AutoConfig, right click and choose properties
- Change Startup Type to Automatic
- Click Start below the “Service Status” text
To be extra-cautious, you could also make sure the order of your network is set correctly:
- Control Panel > Network and Internet > Network Connections
- Advanced menu > Advanced Settings
- Make sure your Wifi connection (adaptor) is set to the top-most entry
Why does this happen?
Seems it could be a multitude of reasons; it might be that your network card got in a tizzy and or that some condition occurred where your system disabled it. If it keeps happening, this could be a more significant issue. I would do the following:
1. Virus scan your system – I usually use Microsoft’s own Virus scanner as well as Malwarebytes AntiMalware
2. Make sure you have the latest drivers for your network card
