Cannot See Computers in Workgroup

[munruss]

Strange one. Just upgraded my router to a dlink DIR-655. All is stable and working fine. Wireless network is up and running with matching SSID with both router and wireless devices. Laptops are Vista.

Network Discovery/File Sharing is enabled and the proper network services are running.

Any reason why I cannot see any computers on my network?

I can ping them by IP and computer name.

Check their IP addresses and subnet masks. Make sure the IP addresses are on the same subnet.

Software Firewalls Trusted Zone (or what ever it called on your Firewall) has to be adjusted to the New IP scheme.

Also check the Permissions.
----------------
Permission and Security issues with Vista/Win7, check the following settings.
All users that are allowed to share need to have account on all the computers that they are allowed to connect to.

Everyone is an account, it means a group of all of the users that already have an account and been established as users.
Using the Everyone feature saves the need of configuring permission to each of theestablished users, it does not mean Everyone that feel that they would like to login.

Users that do not have an account on the computer are Not part of the Everyone Group.

If security on the LAN is Not needed and users are Not established, then switching On the Guest account provides semi-open configuration.

---------------------

Point to the a Folder that meant to to be share. Right click and choose properties.
In the properties

Click on the Security tab shown in the pic bellow to the right) and check that the users and their permission (shown in the pic bellow center and left) are correctly configured. Then do the same to the Permission tab.
This screen shot is from Win 7, Vista's menus are similar.

In both the Security panel, and the Permission panel you have to highlight each User/Group and examine that the Permission Controls are checked correctly.

When everything is OK, Reboot the Network (Router, and computer).

* Note . The Groups and Users shown in the screen-shoot are just an example. Your list will look the way your system is configured.

Thanks! This is what happened. I had a Buffalo router and used a SSID name for a long time. Then, I purchased the dlink DIR-655 and used the same SSID name. So, all I had to do was minor modification on my wireless devices. All I did was bump the encryption from WPA to WPA2. Everything else stayed the same.

I noticed last night that I was able to see all computers on my network when I changed the SSID and the workgroup name to something else. When I tried to use the original SSID name, I couldn't see the computers again.

So, there is something up with the original SSID name with my wireless devices. I had cleared everything out and started over...no dice! I'm using a new SSID and workgroup name and all is fine.
