Hello all,

I have a sony laptop that has been rebuilt and is connected to our domain. However, after rebooting and attempting to log in. I get the dreaded grayed out login and delayed login and I have pinpointed the issue to the wireless card. If I turn the hardware switch off I can login within seconds, when the switch is on the login in process can be upto 5 mins. Having the client turn the wireless card off during login and turning it back on is not an option.

The wireless card is a Intel® Centrino® Advanced-N 6200. There is only one wireless network profile in windows wireless, I have also removed this as well. I have ensured all updates windows, bios, and system updates have been applied and have even used two different wireless drivers one directly from the Intel and the other from Sony's website to no avail. I made sure to uninstall the Intel Proset wireless software and only installed the drivers.

I have hard coded the dns and ip and ensured dhcp is correct. I have flushed the dns. I've installed and reinstalled the wireless drivers so much that I am upto wireless local area connection 11.  I am at a loss.

Unfortunately I cannot test a different wireless card on this machine. I can state that after I initially logged into the computer using the client's credentials and a few restarts afterwards, I had to reinstall the standard software [office 2007, Adobe acrobat pro], the login process was immediate. I only noticed the issue when I was preparing it for pickup and went to make sure everything was correct as this is for a high level client in my company. We do not support sony laptops and thinkpads, but this is the exception to the case.

I reckon you need the right type of drivers for you machine viz the wireless card.
You can down load the right drivers from

Hi Asidu,

I've downloaded the wireless drivers both from the sony website and through intel. Both drivers different versions give the same issues.

Model - Sony VPCZ-11HGX/X [You will find it labeled VPCZ11HGXX under the models list on sony's laptop]
Wireless card is a Intel Centrino Advanced-N 6200
Drivers I've used so far are
Sony's website File Date 02/03/2010 File Version 13.0.0.107
Intel's Website File Date 3/4/2011 File Version 13.¿5.¿0

The sony installer is silent and does not have much user interaction. I have found where the file extracts itself into the temp folder and ran the setup file from there so that I can tell it not to install the proset utility I have also done this in reverse and had it install the proset utility, but regardless if windows is controlling the wireless or if the intel utility is the login speed is the same.
Also when I remove all wireless profiles, the initial login is fine. So it appears it's getting stuck trying to connect to the WPA2 network we have. If anything is there a way that I can have the logon process forgo waiting for a network connection until after it has loaded into the desktop.

Hi Nice85,

The two important drivers you need are:

and



Install the two drivers and test.
I suggest you remove the current wireless drivers.
Let the system reinstall the drivers after getting the above drivers.

Hi asidu,

I appreciate your efforts in this, but as I stated in the original post. I made sure to do ALL updates including windows and any system updates including the bios update and sony's "special software"

If I remove the WPA2 network from the wireless profile, the laptop logs in like it should ~20-30 seconds. However, if I have the WPA2 Network takes upto 2-5mins. We do have a hidden WEP network and an unsecured guestnet. If I have these profiles in the wireless profile the initial login is fine.

After I isolated it down to the wireless network. I went to check the configurations. I noticed that authenticate as computer when computer information is available was checked. After unchecking authenticate as computer when computer information is available the speed of the login went back to ~20-30 seconds. I am now going to have to replace my desk as it has the molding of my forehead in it. Thank you for your assistance asidu and tjdabomb.

Glad that the problem has been pinned down. That line of approach was not in my mind. Learned some thing new from this problem.

Good luck to you!

After isolating it to a particular wireless connection I was able to resolve the issue. All other suggestions were driver updates that I've already stated I had done in my original post.
