You could try different Darkwake values in your config.plist.

Try turning off Wake on Lan (WOL).

I solved it by installing IntelMausiEthernet from Multibeast. I have Asus Maximus V Gene Z77 with Intel 82579LAN controller.

Didn't fix it for me.

I fixed it by setting the ACPI Suspend Type to SI(POS) (Power on Suspend) rather than S3(STR) (Suspend to RAM). This is on an AMI BIOS.

SOLUTION (for me at least).
Use AppleIntelE1000e.kext, v3.3.3. Later versions cause this problem. I tried v3.3.5 and 3.3.6, but not 3.3.4 as I did not have it lying around, and both cause the problem. I tried installing them in S/L/E and L/E, one at a time.
My MoBo (GA-Z77X-UD5H, rev 1.0) has an Intel NIC that is not supported by IntelMausiEthernet.kext, so this was not an option for me.

Check your current version of this kext in S/L/E or L/E. If it is not v3.3.3 then: 1. make a backup copy; 2. move it to the trash; 3. install v3.3.3 to L/E using KextBeast. Note that L/E is now Apple's preferred location - I read this somewhere while trying to fix this issue; 4. Reboot; 5. Test sleep/awake.

Post back if this works for you as this will helps others.
If this does not work for you then you have your backup copy of the kext to put back in using the method above.

Thanks StuffMac it worked for me on High Sierra though I didn't use KextBeast and fortunately had an old drive that still had El Capitan on it, so had access to the right kext (I think). Also my mobo is slightly different GA-Z77X-UP5 TH but it worked and thats all I care about (-;

On Mojave with Smbios 15.1 and Z97-A board, I had to remove AppleIntelE1000 and install IntelMausiEthernet v2.1 to fix the problem of Internet disappearing after sleep!

Downgrading to AppleIntelIE1000e v3.2.4.2 (included in MultiBeast) seems to have fixed the issue for me. At least when manually sleeping the computer.
