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?
