I have Windows 7 SP1 64 bits.
Also have a WD My Book World 1 TB with firmare 01.02.06 with MioNet 220.127.116.11
Both connected to a wi-fi router Linsys WRT54G.
It use to work fine. When I was using AVG Internet Security with it’s firewall.
When AVG’s license expired, I uninstalled it and installed Microsoft Security Essentials and activated Windows 7 Firewall with it’s default settings.
Now, when I go to “Computer”, in “Network” (left panel) doesn’t show my WD My World Book.
But if I type “\MyWorldBook\Public” I can access the folder. I can link it as “Z:”
Network map shows My Book World, my PC, the Linksys router and Internet. http://tinyurl.com/3cs9qqa
What I found is, if I turn off Windows Firewall and reboot PC, I go to “Computer” and under “Network” in the left panel, I find the device “MyWorldBook” and my PC. http://tinyurl.com/3vzjo9a
If I turn on Windows Firewall, a few seconds after the “MyWorldBook” and my PC devices disappear from “Computer’s” left panel. However, mapped units works fine. Same if I type manually “\MyWorldBook\Public”.
Specifically, I have to turn off only a part of the Windows Firewall: Public Networks. Don’t know why., but if “Private” part of Windows Firewall is enabled, “MyWorldBook” device is under “Network”.
So, I think that some rule/s in “Public networks” part of Windows Firewall are interfering. The thing is, I can’t find which one.
I found this topic: http://tinyurl.com/62seyeh I think is the same problem.
Hope for any help. In the mean time, Windows Backup works fine even if the device isn’t under “Network”.
