Need to Disable and Enable Wifi and LAN on boot to connect

Hi experts,

I have a (3 month old) Sony Vaio S laptop, that has a connectivity problem for the last 2 months.

Every time I boot the laptop, I need to "disable" then "enable" the WiFI adapter or LAN adapter (depending which one I want to use) before it will connect.  The attached 7 screenshots show the process i take, including ipconfig settings at the time.

I've tried:
 - installing the latest drives from Intel website
 - updating all other drivers from the Vaio Update tool
 - ensuring Windows Update is 'up to date'
 - resetting the IP/Winsock stack through netsh
 - unchecked theadapters "Allow the computer to turn off this device" property.
 - this is experienced both at home, at my work, and at client offices, so I can discount a router problem

What is odd is that the WiFi card is Intel, and the LAN NIC is Realtek... but both exhibit the same problem.

I've also experienced a few BSOD's when waking from sleep, which point to NDIS.dll being the problem (I used BlueScreenView to get that).

Sony support want me to reinstall the OS; which seems extreme to me.  Its my main source of income (being a  traveling software developer) so it takes ages to setup with all my applications and so on.  Reinstalling the OS is just not practical.

I'm hoping that this is something that has been experienced, and identified before...

Looking forward to your help!

Thank you,

Deactivating AV products and/or firewall softwares does not remove their filter drivers. For a real test, uninstall those and reboot.

Upload dmp file for analysis.


If possible disable virtualbox network adapter..reboot and then check.

I would backup my data, return the computer to Sony and tell them to fix it.

What does the output from ipconfig /all look like before you disable/enable the adapter?

Does this occur anywhere?  Or just at certain locations, say like only at home and "location#1" and then it works correctly at "location#2"?

Thanks all for your comments.

 - actually I've no AV installed (corporate Kaspersky not deployed .. an oversight!)
 - firewall is standard Windows firewall which i don't believe can be removed

 - Virtualbox was installed shortly after purchasing the laptop, so it very well could be when the problems first started.  This is therefore was a good place to start, so  I uninstalled VirtualBox completely, yet the problems still exist.
 - Minidmp .. eeehhh.. yeah, I have one.  Very reluctant to upload the files I have as they do contain identifiable information (and I do have certain 'clearances' to consider).

 - I've come close to that!! I've contacted Sony a few times, but there inevitable suggestions always end up with a full factory reset, which I'm trying to avoid.  But at some point I may well just DBAN and return for a replacement.

 - ipconfig /all doesn't reveal any more, that to list the same adapters as per screenshots (albeit with information about those adapters).  My point of the screenshot was to show the WiFi adapter "missing", even though it was present and correct (showing as enabled) in the network Connections dialog.
 - it occurs in multiple locations - in fact I've traveled to 3 different countries, attending multiple offices in the last few weeks, and the behavior has been the same .. so its definable not the router!

So - further progress.

Around the same time that VirtualBox was installed, I had also installed (and paid for) Stardock's Start8.  Out of sheer blind luck I thought: lets disable that service, and restart...

 - no further WiFi problems.
 - no further BSOD's on sleep.

I'll be getting my money back then.

Thanks for the input guys, you might not have hit the answer, but it helped focus what I should look for.
