I have a dlink 825 wireless router (just 1), and all my wireless devices work just fine, they are connected via the 2.4ghz band. Even the xbox that connects wirelessly works online fine it just doesn't see the network drive.
I have one PC that is connected wirelessly and one that is wired. Both see the dns-323 as VOLUME_1 and VOLUME_2 (I have 2 drives) and I can access everything regardless of wireless or not.
Also, I physically plugged the xbox into the router and it still doesn't see the drive. So it doesn't appear to be a wireless issue, perhaps an xbox settings issue.
All help and suggestions are appreciated.
