I just set up my Synology DS213J at the weekend and everything went well, apart from my sons PS3. Basically, the NAS works well with other wired and wireless devices in my home network apart from a wireless PS3. It streams perfectly to my other PS3, although this is wired. It also connects perfectly to a wireless WDTV which is located right beside the problem PS3. I may be wrong, but I have ruled out a router issue as it works with other devices wirelessly. I have also checked settings on the problem PS3 and media server is enabled and it says UPnP is okay. Therefore, I think it must be related to having two PS3's on the same network, but I just can't solve it. Any assistance would be greatly appreciated.
