Are you sure it's Win 7 and not the router or network config that's causing the problem? Could you try a direct connection or via a different hub, switch or router?
I know it doesn't help but I can confirm I have no problems at all with my 2TB GF Home, it sits on a gigabit ethernet switch (for high speed powerline and direct connections) and via this switch to a venerable old Netgear DG834 ADSL WiFi router. We have 2x Win7 64 bit laptops in the household on WiFi and the GF Home always appears and the drives map correctly. This is with the Seagate dashboard software installed.
One of these Win7 laptops is also used monthly with a direct gigabit ethernet connection for backing up the GF Home to an external usb disk: this is done using a batch file which performs several command line drive letter re-mappings to access each user's folders. Again no problems seeing the GF Home.
Other computers and laptops (still on WinXP) in the house use either WiFi or powerline connections. I didn't use the Seagate dashboard with these, just set up persistent mapped drives through Windows Explorer.
Our stand-alone media player and smart TV find the GF Home UPnP service every time. Films play all the way through no problem.
In short, the GF Home just works and is there on the network whenever we want it.
So what on earth is going on with your setup I wonder? I do hope you get to the bottom it, but it seems to me there are a lot of possibilities and it's probably very difficult to diagnose via forum posts.
Some things I would recommend are:
1) ensure all devices are on the same tcp/ip subnet and the same windows workgroup where applicable
2) give the GF Home a static ip address and reserve this in the router.
3) set up the GF Home user names and passwords exactly the same as the Windows user names and passwords - this allows the network connections/drive mappings to work without having to store specific authentication details in Credential Manager.
