Wireless connection is lost when the wireless session times out in Windows 7 or Windows Server 2008 R2

This article describes an issue that occurs when the wireless session times out in Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1. A hotfix is available to fix this issue.

Symptoms:
This issue occurs when a Windows 7-based computer is connected to a wireless network by using the Wi-Fi Protected Access II (WPA2) protocol and the wireless access point (AP) starts a new exchange of WPA2 keys. In the four-way handshake, the Windows 7-based computer sends a Message 2 (M2) with an invalid message integrity check (MIC) and secure bit.

Note This issue may occur every 12 hours or more frequently, and it takes one minute to regain the network connectivity.

Cause:
This issue occurs because the WPA2 key context is not set correctly before the four-way handshake rekeys. Certain variables are not reset after the previous four-way handshake. This causes the secure bit to be set incorrectly and the stale Pairwise Transient Key (PTK) to be used to calculate the MIC in the M2 key messages. Some (specifically but not limited to Cisco) APs reject the M2 messages because of these errors.
