The LAN cable may be faulty. Try using another LAN cable.

Samsung Smart TV makes noise lasting 3-5 seconds then produces Network Cable messages. Started 2 days ago and is happening more frequently.


You could check to see if Samsung has a Firmware upgrade for this issue at their Consumer web site. Doubt it will fix your problem though. Are you using a wired LAN connection? If so then check it and make sure it is not loose, or that your router has not been powered off. If all checks good, or you are not using a wired LAN connection you will need to replace the main board. I can not give you a part number because you did not include your model number in your complaint. I hope this helps.

I am getting a 'Check Network Connection' error message. I have checked all wires and turned the copier on and off again but the message still comes up. Grateful for assistance with this


Check network connection means that the device is not communicating with the local LAN. This could be due to:

  1. Cable connection to LAN interrupted
  2. Wireless connection (if used) not enabled
  3. IP address settings incorrect
  4. WLAN validation password incorrect.
Check to ensure that the network settings are correct in the configuration menu. Ensure that if you are using a wired LAN that the LAN cable is connected between the copier and the LAN outlet.

Can't configure the network with ethernet cable


Hey, you're almost there. The connection between the no-wireless PC over ethernet to the DAP-1360 Repeater is fine. The reason it can't connect to your LAN or the internet, however, is that the repeater isn't actually repeating your Ofir network, it is instead creating it's own, completely isolated wireless network (Ofir_EXT).


The D-Link setup and documentation is confusing, and doesn't have proper instructions for the repeater setup.


Rerun the setup wizard, setup as a repeater, then select manual configuration method.


Now, enter the wireless network name of your the network you want to extend (in this case, Ofir). Then enter the same security and password etc. for Ofir in the following fields, just like you were connecting to Ofir from a smartphone or laptop.
Once that is finished, you should be up and running. If things worked, you should NOT see any new wireless network. There should be Ofir and just Ofir. Wireless repeaters work invisibly, you'll still connect to the same network like you always did, but now it will have much improved range thanks to the DAP-1360. The computer entherneted to it should be networked on the wireless LAN and have internet access after this as well.



Good luck, I hope my instructions were clear. Wifi networking is easy, it's understanding all the manufacturers less-than-intuitive software that makes it hard.

"Ethernet cable unplugged"


A few things to try. Plug the cable into a different port on the router to rule out a bad port on router. Try a different ethernet cable (they do go bad). If this is an older router it may not be able to do logic swap on the pins and you would need to use a cross-over cable and not a straight through. Also check in device manager and make sure the computer is not allowed to disable the lan adapter in power saving mode. Also if your really want you can test your ethernet port by buying or making your own loopback plug. Look up ethernet stander T568A. You basically would buy a empty ethernet jack and run a short wire from pin 1 to pin 3 and a wire from pin 2 to pin 6. This will simulate sending data to another device (the other device will simply be the receiving pins on your own ethernet jack.

When I connect my Linksys WRE54G to PC with lan cable. Always get the message "Site survey fail"


> Site Survey fail

It's your wireless adapter that is "sniffing" for available Wireless Networks, and is finding NO networks.

Disable your wireless adapter, and connect the Ethernet cable, to exclusively use the "wired" connection.

Had 3 d-link routers that keep giving off the error message that the "network cable is unplugged" all different models at different locations connected to differnt computers any ideas?


Hi, either there is a broken cable or faulty connector some where or the Lan card in your pc is faulty.

1/ Check all cables
2/ start with one router and connect that up by its self, without any other router.Connection should be made as close to the pc. You know the usual setup, modem,router,pc.
We are trying to narrow it down.

If pc still says network cable unplugged then make sure the lan card, in your pc is seated properly.Are you using a seperate lan card or the the motherboard connection.

I have just found that this product was discontinued in 2003,you are probably better of buying a new one.

But any how let me know how you get on.

Its always show at the the monitor the " A network cable is unplugged".


If you are connecting to the Internet using a wireless connection and your LAN card in the computer does not have a LAN cable connecting it to a hub or router then you will get a message "A network cable is unplugged".
If you don't use a wireless connection and you only connect to the your network/Internet then the problem is either the LAN cable has come loose in the computer's LAN card or at the router or the LAN cable is faulty.

Due to the power fluctuation my dell laptop 1501 inspron's lan port or network adapter has been burned so whenever i insert network cable in it. it show the message of network cable unplugged


Most laptop lan ports are onboard so replacement would mean replacement of the entire Motherboard. A very costly option. I suggest buying a USB to NIC adapter from your local PC store and just use that for LAN connections.
(side note: get a good brand, cheap USB to NIC/LAN converters sometimes drop connections randomly so spend a few extra $$$ for a good one)
