Network is disconnected
« on: December 23, 2010, 08:19:36 AM »

I have been using my DNS-343 perfectly fine since I got it over a year ago.  I am using firmware 1.03 (with 4 1.5TB drives installed).  Just today after travelling with the DNS-343 for a few days by car and setting it up with a new router, it gets the message "Warning: Network is Disconnected".  When it first boots up, I do see that it is detected on the network since the router shows a connection on the port, but after about 3/4 of the boot cycle, it drops from the network, and is not pingable.  I am guessing it is some sort of ethernet card issue in the DNS-343, but it is odd that it is detected during initial boot-up.  I'm looking for advice to determine if it truly is a hardware issue with the DNS-343, and how to fix it.  I don't have easy access to a cross-over cable, hence connecting directly to my PC is not my first choice.

Thanks,
Eric

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?
Is the DNS getting a Dynamic IP address from the main host router? I recommend using a Static IP address ON the DNS set to 192.168.#.34 or .40.
Swap out LAN cables. Link> Cat6 is recommended.

HI,

What did you do ?

i got the same just today (6 years later ...)

What is the Mfr and model of main host router that your PC and the DNS is connected to? I presume you are using a host router?

model host routeur is tp-link AC 750

i reboot few times for now
it s not always says  "network is disconnected" (weird)

on Traffic Statistics from router i can see now:
Quote

MAC Address    Packets    Bytes    Packets    Bytes    ICMP Tx    UDP Tx    SYN Tx

which 192.168.0.106 is the dns-343 but without mac address

edit:
and with D-link easy search utility,  i have nothing no device and on Firefox no access setting (time out)

Try swapping LAN port slots on the back of the router. Try different LAN cable. Use one from one device that is working.
Power down the DNS then back on after making this change.
Power OFF all devices accept for the one wired PC.

Ya, the DNS is not getting an IP from the router...106?
Which address is your PC?

Possible that maybe something wrong with DNS LAN port. Does it have two LAN ports in back? Try the other if it does.

Mfr = Manufacturer> TPLink

I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Let us know how it goes please.

Ya the OP hasn't been back since they originally posted. So I think phone with D-Link support would have better results. You may have a faulty unit.
Only other thing to try is to take the DNS to a different location and see if it connects. Say a friend, neighbor or family member.

So can you connect to 192.168.0.32 while the DNS is connected to the router with your PC connected to the router as well?

A Few of questions.

1) does the unit complete the boot sequence?
2) do the fans start running at startup?
3) have you tried another power supply? (the 19v 4.74A supply for a laptop computer will work)

The reasons for these questions is that we had similar problems with one of our DNS-343 boxes a few years ago. We used the power supply from an Acer Aspire 9200 to test and everything started working again and has been running 24/7 with that power supply ever since.
A power supply that is beginning to fail will generally supply enough power to start the boot process (the LAN comes early in that) but when the drives try to start the voltage drops causing the switching off quite a number of functions the OLED screen remains working because it is a low voltage item.
