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.
- 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!
