Windows 8.1 reconnect network share after resume from sleep

Hi Experts,
I have pretty simple setup. The computer (DELL Optiplex 7020) freshly installed with Windows 8.1 x64 and all fresh drivers form DELL website. And the Synology DS1815+ with some disks and latest DSM 5.1.
Also there is an old Windows XP machine connected to the same shared folders.

Everything is running fine until Windows 8.1 machine goes to sleep. After resume from sleep, the Windows 8.1 machine is unable to access networkshare on synology, but in same time Windows XP machine can access to synology.

Internet and other network services are available just after resume from sleep.

The solution is to restart computer - it get working instantly...

Have anybody solved that? What can I try?

Check the power management on the Network Cards. The Network Cards may be going to sleep.

Go to Device Manager, click on the NIC and select Properties, go to the Power Management tab and uncheck the setting that says Allow the computer to turn off this device. Do this for all real Network Cards.

Now go to Power Management, Change Plan Settings, Change Advanced Power Settings and set the Wireless power setting to Maximum Performance.

Thank you for reply, I will give it a try, but I dont have problém with all the network traffic, only networkshares are not working. It seems like Workstation service is freezed, but Im unable to restart it (it just cant be stopped) - when the computer is resumed from sleep.

Dell has had difficulty in past with Suspend and Hibernate.  Dell OptiPlex is a Desktop machine and it may be best to turn Suspend and Hibernate both OFF and set power management settings to Always ON. That will work better for you.

Im very very DELL positive (so I am administering many DELLs for my customers each day) and no other computer is doing that, I believe that is Windows error. I need solution, not workaround...

Windows does not cause a problem with suspend, but Dell has caused issues in the past.
