That can also be due to using network drivers that are:
1) Designed for Windows XP
2) 32-bit Unsigned Drivers
3) 32/64-bit driver that's signed but not WHQLed
4) Out of date / Has bugs
5) BIOS bug when resuming from S3/S1
If possible, try to go to the vendor of your computer and update the network driver or the manufacturer of the part and get a reference drive. Make sure the drivers are both *signed* and *WHQL*ed.
