The Wireless driver isn't working on a ' Vaio.
The Ethernet and Wireless drivers showed the yellow triangle with the exclamation mark in Control Panel. My can't seem to find the original CD, so I've downloaded the drivers from the Sony website.
I've installed the Wireless driver(Intel), but now the WLAN option disappeared from the VAIO Smart Network Utility. When I try to reinstall the Intel Driver I get this message:
A newer product version is already
installed
And I can't see the Wireless Adapter listed in Device Manager.
I've downloaded a driver for the Ethernet card: Marvell Yukon 88E8055 PCI-E Gigabit Ethernet Controller, but I had no luck installing it 🙁
Windows displays this message:
The best diver software for your
device is already installed Windows
has determined the driver software for
your device is up to date.
How can I correctly install the drivers and connect my friends' computer back to the internet?

If the wireless is suddenly missing from the device manager after a driver installation, then the only option possible is that you have installed the wrong driver.
I suggest to rollback Windows to a system restore point dating from before the change, if you still can.
We would also need to know the exact model numbers of the wired and wireless cards in order to verify the right drivers for them. If you don't know them, then you could use a free system information utility such as Everest Home or Belarc Advisor.
