We are experiencing problems with Realtek PCIe FE family NICs on certain models of Toshiba Satellite Pro C660 laptops - specifically those fitted with Core i3 processors.
After building the laptops using a standard image you can start Device Manager and see the NIC included in the list of discovered and active devices. The network works just as expected.
If you then do a soft reboot the NIC disappears from Device Manager. It's not even listed as an unknown device - it just doesn't appear at all.
If you perform a further soft reboot the NIC magically re-appears and works as normal. The process is repeatable i.e. the NIC disappears every alternate soft reboot.
If you do a full power cycle
i.e. remove battery and switch off the mains suppy, then the NIC always appears as normal!
I've seen problems listed elsewhere relating to these particular NICs and sleep mode. So I disabled Windows Power Management from affecting the device. I also checked the BIOS for any NIC related power options, but couldn't find any. The BIOS has been updated, as have the Realtek drivers, PCI drivers etc.
The config summary is:
Toshiba Satellite Pro C660 - sub-model PSC0RE seem to be the only models affected. These are Core i3 based so may have a different motherboard from the other C660 models which work fine.
Windows 7 Pro 64-bit with SP1 plus updates ( 32-bit also seems to fail)
These machines are all being freshly built with a standard image created using MDT. The image works flawlessly on a wide range of other hardware. No Realtek drivers are embedded in the image. These are install either by MDT, or manually during testing/debugging.
Realtek PCI Express NIC drivers V7.094 - the latest from their site.
Grateful for any help anyone can provide. Starting to run out of ideas.
