Cannot see my network on Windows 7 running under Parallels 10
Probably the virtual network interface of your Windows 7 VM uses "Shared Network". Reconfigure the NIC to bridged network and choose Ethernet or Wi-Fi (like indicated in the screenshot below) depending on your network configuration:


if your iMac is connected to the Linksys XAC 1900 via Ethernet choose "Ethernet"  
if your iMac is connected to the Linksys XAC 1900 via Wi-Fi choose "Wi-Fi"  




You might want to check the Firewall configuration in your Windows 7 VM as well. If the settings are to restrictive the network devices won't be visible.
