I have an HP Pavilion DM4-2070us with Windows 7 Home Premium (64-bit).
The Wi-Fi network adapter installed is a Centrino Wireless-N 1000.
For the past four weeks it has taken "forever" (about 3 minutes) before the laptop can connect to the Wi-Fi network. Upon booting up, a red "X" appears on top of the wireless network icon (the icon with five
vertical bars) in the Taskbar. Approximately three minutes later the red "X" disappears and I have Internet connection.
I am current with Microsoft patches and I have even installed the most current Centrino Wireless-N 1000 driver that I could find at the Intel web site. (The HP support site was of no use...)
I have opened a command prompt as an administrator and entered these commands:
netsh winsock reset catalog netsh int ip reset resetlog.txt ipconfig /flushdns ipconfig /release ipconfig /renew ipconfig /registerdns exit
... and rebooted the computer. Things did not improve.
I have a couple of other laptops that are connecting to the same Wi-Fi network without problems, so I don't think that it is the router to be blamed.
What could possibly be the culprit of this sudden three-minute delay in connecting to Wi-Fi?
