I have a work L412 laptop running XP Pro that I use alongside a Lenovo docking station connected to the work gigabit ethernet network. When I remove the laptop from the docking station, I am unable to connect to the work wireless network as I just get "Acquiring Network Address", or "Attempting to Authenticate". If I switch the wireless switch off and then on or run the "Repair" option for the NIC, just end up at this same stage. The only way to restore connectivity is to reboot the machine. However, if i boot up the machine out of the dock or not connected to ethernet, I can connect as usual. The problem seems to point to the machine refusing to use wifi after it has been disconnected from the ethernet. I have updated the wifi drivers to the latest version, enabled "Aggressive Roaming" and turned off the option allowing the machine to turn off the wireless to save power. Is there anything I can do to rectify this problem?

Have you received any response from Lenovo? I also have the same problem, and cannot switch between Wired/LAN to Wireless. It's like the system doesn't see it disconnect and tries to stay connected to the previous adapter.
