Connectify Filter Driver Is Disabled
Connectify Hotspot relies on a filter driver to provide Internet to your devices. Sometimes this driver can get disabled, for example by some anti-virus software or by Windows Updates. To re-enable the Connectify LightWeight Filter driver, do the following steps:
1. Open the Network Connections window (Windows Key + R > Type 'ncpa.cpl' & click 'OK') or through the Hotspot UI (Tools > Network Connections)
2. Right-click on your adapter and choose Properties
3. Check the box next to Connectify LightWeight Filter in that window and click OK.
