Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Please give me some details as to what is happening.
1 - has this setup worked before, where it is?
2 - how old is the DiskStation ?
3 - any major events lately, for the DiskStation, or the network ?
4 - if a login to the DiskStation is required for your computer to see it (i.e. for it to be visible in Finder), then is it logged in, on that computer ? even if you think it is logged in, sometimes the login and authorization state can be so 'jammed up', that you have to log out completely, restart the computer, then log in again, to get it working/authorized/up/found again.
Thank you for the very articulate and detailed roundup of the components of the situation.
I must clarify for myself:
It isn't that your computer isn't accessing the DiskStation... you can access it from Safari on your computer.
How do you access it from Safari? through what URL or what sort of URL (please do not post any username or password ***** this is NOT a secure forum and your information will be visible to anybody.)
OK. Thanks for clarifying.
Now I think this shows that what I said before, could be the case.
But you say there's a PowerLine network adapter involved, and also your Apple TV is not recognized or not on the network.
Is the PowerLine adapter connection vital, or on the link that leads to, the DiskStation ?
Ideally, I would conjure up a network map with wizardry.
But instead, let me ask a series of questions, please:
1. Diskstation-to-Extreme by Ethernet or Firewire, OK.
2. Apple Mac computer by Ethernet to PowerLine adapter, OK.
3. Then, what is there between PowerLine and Extreme ?
When you access the DiskStation through its IP Address etc. in Safari browser, you're using a somewhat different method than going through the Finder.
The issue I raised about authentication or login status when accessing through Finder, might be valid.
But also, what's the network path that Finder has to take? if it is hopping through too many routers, too many bridges, too many adapters (probably the PowerLine adapter, since they often throw a loop into local networks), then it may simply not be possible.
Make sure you're logged in! as far as the computer is concerned, not just the access-through-Safari... to the DiskStation.
(Or is it, that Finder ought to prompt for login, for username and password, and doesn't get that far?)
I think the issue would be best addressed this way:
1. determine your computer's IP address
2. from that determine the address range of the PowerLine adapter (likely to be a problem.)
3. And let me know the DiskStation's local IP address (if it isn't something like
then don't let me know what it is, please.)
When you configured your Powerline adapter, you must have configured it to a network IP Address, correct?
Do you know what that was?
Thanks, ***** ***** not needed. Just trying to assess what sub-net each part is on.
Then I confess I don't have a solution to this.
It's best that I Opt Out of the case, with apologies. ... but first:
Can you open a Terminal window on your Apple computer? (Ctrl-T will do that, usually.)
Then type this info the Terminal window (assuming your DiskStation's IP Address locally is 192.168.1.10, but substitute whatever that address actually is into the command):
and let me know what responses the command produces (mind: put in your DiskStation's actual IP Address on the local network, like the one you put in the URL when accessing it in Safari)...?
OK. Hold Ctrl, press C, to end the command.
In case I didn't get through... what is the IP address of your DiskStation, as entered in Safari when accessing it through Safari browser?
What results do you get from
No network path or not a ping-path.
I've run out of ideas and must Opt Out. This opens the case to other Experts. Thanks for your patience so far.
