Unable to enable Wireless Adapter in Windows 7? blame Kaspersky
I recently encountered a pretty frustrating problem: on a laptop with Windows 7 installed, I could not enable the Wireless Adapter.
It was pretty weird: in Device Manager, everything looked good: the device was “working properly”. Yet I did not see any wireless networks. In Control Panel\Network and Internet\Network Connections, I noticed that the Wireless Adapter was disabled. I could right-click on it and select ‘Enable’, but that did not change the status: the Adapter stayed disabled.
Network Diagnostics reported there was an “unknown” problem with it. Not very helpful. I googled for hours, tried all kinds of things (disable/uninstall-reinstall/tried older versions of the driver/…) until finally I found this post which gave me a hint: apparently, Kaspersky anti-virus was the culprit! The Kaspersky NDIS filter caused the issue.
Process to solve it:
- Right-click the Wireless Adapter in Control Panel\Network and Internet\Network Connections, select Properties
- UNcheck Kaspersky Anti-Virus NDIS filter
- Select the Wireless Adapter, click Diagnose this device – to reset the adapter
Et voila, I (finally) had a working wireless connection again.
