File Explorer goes from a shared directory to "Network" after waking from sleep

When I open a network shared directory with File Explorer, and put the computer into sleep, and then wake it, File Explorer's address is changed to "Network" and a yellow notification bar shows the following message:

"Network discovery and file sharing are tued off. Network computers and devices are not visible. Click to change..."

Can I make File Explorer remain at the same shared directory, in this case?
