In wireless networking there might be different causes for drop connection issues besides the driver:
- Interference: possible sources can include cordless phones, microwave ovens, and other 802.11 Wi-Fi networks. Check that the channel your access point or wireless router is using, is not overlapping or in use by another nearby access point. Software tools such as inSSIDer* can be useful to help select the best channel for your access point or wireless router. If using 2.4 GHz band, use only channels 1, 6 or 11. You may also use the 5GHz band if the router is dual band capable.
- Firmware: the firmware of the router if outdated may cause unexpected behavior with newer devices. This may occur with certain router models only.
- Conflicting software: Antivirus or firewall software may interfere.
- WiFi security (authentication) settings: Choose a good security type and verify the settings in the router and the client’s wireless profile match; avoid mixed settings (TKIP+AES) whenever possible. For troubleshooting purposes you may test with the connection as unsecured and check if the issues still occurs.
- Hardware integration: the wireless adapter or antennas could be defective or not properly installed. The wireless adapter is sporadically not being detected by the system (in BIOS or operating system). You would suffer from connection drops all the time and every network.

I suggest you checking all possible troubleshooting steps at your disposal; we are investigating the issues that are not solved with latest driver. Please verify if you get events with the IDs 5007 and 5055in the Windows* Event Viewer (Control Panel, Administrative Tools) at the time the issue occurs. Kindly share the details from those events if available. Information such as operating system, AP brand and model, firmware version and authentication method is also valuable.
