Consider the following scenario:
- You connect a Windows Vista-based computer to a wireless
network.
- You put the computer into hibernation (S4).
- The computer resumes from hibernation and then tries to connect
to a new wireless network from its preferred network
list.
In this scenario, the computer waits 30 seconds before it starts connecting to the new wireless network.
This issue occurs because the Nwifi.sys component waits 30 seconds for the wireless network scanning process to finish. If the original network cannot be found during this 30-second period, the computer tries to connect to a new wireless network from its preferred network list.
A hotfix is available to reduce this 30-second delay to 10 seconds.
Note If the computer takes longer than expected to connect to a wireless network, this hotfix may not resolve the issue to your satisfaction. This hotfix is intended only to reduce the length of the wireless network scanning process by 20 seconds.
