My DIR-825 Rev B1 reset to the factory defaults the other day so I decided to upgrade to the FW Ver. 2.09NA that allows current dates since I had to reprogram it anyway. The FW update went without a problem and did as advertized.
Since I was resetting the router, I was trying to include reasonable security protocols for the network to allow me to implement VPN and remote access protocols for the network. I turned on the IPv6 feature. When I did this, the workstations in the workgroup could no longer access either the shared drives on the server, or the shared drives on the other workstations. This was true for both the wireless signal and the ethernet. When I switched the workstations to connect wirelessly to another DIR-825 Rev A1 using IPv4 protocols, the workstations could find the shared drives on the server and the other workstations. All the workstations and the server are running Windows 7 Professional 64-bit.
Is this normal? I knew that most cell phones and tablets don't work with IPv6. I thought that these workstations with all the latest updates and drivers would not have any problems with IPv6.
Are there other features in the router setup that might have caused these sharing failures? I enabled set TCIP addresses for all the workstations.
