My first DNS-320 failed so I got a replacement from eBay. Trying to set it up, have put the old HDDs in. Running D-Link Sharecenter Setup Wizard, it recognises the NAS as 192.168.0.32 but when I click on it, the power LED doesn't blink as it should, and I can't log in. I have tried pressing the recessed reset button. Both NAS and PC are connected to my router by ethernet. I can't log in to that IP address in a browser. Is this replacement also faulty?

Link>Welcome!

• What Hardware version is your DNS? Look at the sticker behind or under the device.
• Link>What Firmware version is currently loaded? Found on the DNSs web page under status.
• What region are you located?

What Mfr and model is the main host router?

Remove both HDDs and see if you can get the set up wizard to work? Try installing one new or a drive that doesn't have anything on it and test...

PC Web Browser Configurations
What browser are you using?
Try Opera or FF or  IE11

[RobertSteed]

Thanks. It is hardware version A1. I can't tell what version firmware is loaded because I can't log on to the NAS.
I've tried Cyberfox (based on Firefox), Microsoft Edge and IE 11 - it makes no difference.
I'm in the UK.
The router is Huawei HG633.
I'll try to find a spare HDD for testing tomorrow...

Robert, another thing to try.  Download Netscan by SoftPerfect https://www.softperfect.com/products/networkscanner/ , assuming you are using a windows operation system (32 and 64 bit versions available in the same zip file and it is free). Unzip it and use the correct version for your OS and start by setting the IP range as 192.168.0.1 and end with 192.168.0.254 then click on run and let it do its thing.  It should show you the IP address if every running item on your network and, hopefully, the NAS will show as 192.168.2.32.  If it doesn't then you have a problem which may or may not be fixable.

EDIT:
Because it didn't feel right I looked up our copy of your router manual and assuming you haven't changed the DHCP settings (can you even do that with the TalkTalk supplied unit?) and find the IP range is in the 192.168.1.1 subnet.  Therefore you need to set the IP range in Netscan to 192.168.1.1 and 192.168.1.254 then your NAS should appear somewhere in that range.  If you find it just put http://192.168.1.xxx (with xxx being what is shown in Netscan) in the address bar of your browser and you should get access to the built in webUI which will allow you set the unit up.

Thanks for your help ivan.
I didn't change the DHCP settings. SoftPerfect Network Scanner didn't find the NAS in the range 192.168.0.0 to 192.168.0.255 nor 192.168.1.0 to 192.168.1.255. In fact it doesn't find anything in the former. Sharecenter Setup Wizard still comes up with 192.168.0.32. The NAS doesn't appear in the router web interface connected devices list.

OK, the fact that you haven't changed anything on your router means that everything on your network is in the 192.168.1.0 to 192.168.1.255 subnet.  The fact that the CD based setup wizard 'finds' the defaults is not that surprising when it has nothing to find.  We have never used that with any of our, or our clients, NAS boxes (it doesn't run on OS/2 which is what we use).

Now, a couple more things to check before declaring the unit a lemon.

1) with the unit powered up and the network cable connected do the LEDs on the network socket light and does the router indicate that there is a physical connection?

2) with at least one disk plugged in does the disk LED show any activity at power on?

3) as one of my service girls just said 'check that the power supply is giving the correct 12v @ 3A.

[RobertSteed]

1) The LED to the right of the ethernet plug in the back of the NAS is flickering indicating network activity, presumably.

2) The disk LEDs come on briefly then go off, then come back on solid for several seconds, then flicker for a short period (you can hear the HDD activity) then they go back on solid.

3) 12V 4A you mean. I don't have a multi-meter or whatever is used to test a power supply. I have two PSUs, the one from my original DNS-320 and a third party replacement I bought. The NAS behaves the same using either.

[FurryNutz]

Look at your main host routers DHCP IP address clients table, do you see an IP address listed there for the DNS? If so, what IP address is listed here?

Thanks for your help ivan.

[RobertSteed]

That's what I meant by "The NAS doesn't appear in the router web interface connected devices list" - the NAS doesn't show on the router.

[FurryNutz]

Any chance you can test the DNS out on a different router? Just to see if it could be a router issue. I presume if the DNS does the same thing with a different router, you may have another bad unit. 

[RobertSteed]

I can't use a different router but I tried connecting this PC directly to the NAS with a cross-over ethernet cable, and nothing came up when trying to connect, nor in SoftPerfect on the same subnet (192.168.56.n). I could try the unit on my dad's router tomorrow as I'm going to his house.

[FurryNutz]

Ok, seems like this unit is bad too. If you can try at your dads as one last effort to see. Then you'll know.

Crazy that you have seen two bad units...

You say the LED to the right of the network socket is blinking, is the LED on the left on solid?

Yet another thing to try if you can borrow a network switch. Cable the NAS to the switch and also cable the router and your computer to the switch then see what Netscan can find.  What this does is remove the router from the network, just leaving it as the DHCP server and internet gateway (this is how we setup our clients and individuals that want us to setup their systems. Ourselves, we use managed gigabit switches and our main server as the DHCP server, internet access is by an ADSL modem).

If you can't get it to work the last resort is to take it apart and inspect the solder joints around the ethernet socket for dry joints because everything sounds as if it is working - you just can't connect to it.

[RobertSteed]

The left-hand light comes on and flickers at start-up, then stays off, and the right-hand light flickers. What does the left-hand LED indicate?
Alas I don't have access to a switch nor any knowledge of soldering etc.

[ivan]

The left LED is the connected speed indicator and shows a solid colour when connection and speed have been negotiated (it should be a solid colour all the time). 
The right LED is the activity indicator and blinks when there is activity on the network.

The fact the left LED blinks says that it is trying to negotiate a speed for connection but appears to not be able to do so (LED off).  This could indicate several things, 1) a bad cable, 2) a bad connection to the router, try another port (can be checked by using a switch ), 3) the NAS may be set to a fixed IP address that is on a different subnet (hold in reset button for 15 seconds at startup of unit to return to factory defaults), 4) the unit might be faulty.

There have been cases where, for some unknown reason, a router and NAS box will not work together.  We have always solved this problem by using a simple 5 port gigabit switch available for under 20 euro (it also allows expansion of the network at a later date as well as positioning a wifi router in an optimum position).
