I'd suggest updating the NIC driver in Device Manager. But, the message "A Cable is Unplugged" tells me that the NIC port, the CAT5, or the port where is is connected to your modem/router may be faulty. Try moving the cable to a different port on your modem/router, first. Then, try another CAT5. If still a problem, the NIC port is probably faulty. Hope this helps.

    Since those suggestions didn't work, the modem/router could be faulty. Connect your CAT5 cable with another PC or laptop. Let me know.

My Dell desktop using Windows XP can't connect to my Belkin 5720 router but my laptop still works?


This sounds like a hardware failure, but just in case go to your computer Control Panel-Network Connections(Network and Sharing Center for Vista and above), and check your Network adapter settings. If your Network card is not showing, you may have a driver issue, or a bad NIC (Network Interface Card). It shouldn't matter that your router says" wireless hardware not detected", because you are hardwired from the computer to the router. I would check to see if you may have turned off, or blocked Ethernet connections on your router, I would then change my Cat5 (Ethernet) cable, and finally open the desktop and change out the NIC (Network Interface Card).

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)

I am a Support Tech for the Army and really can't find a solution to this problem. When I plug in my Cat5 cable it still says network unplugged only on my M90 computers, all other Dells I have connect find...


Perhaps the "other" Dell's network cards have auto-sense, and you're using a crossover cable... when you shove it into the M90, you get nothing because the wiring of the Patch Cable is not right.

Try a known good "straight through" patch cable.

Wireless connection works but no plug in connection


The wired nic in your laptop will have a separate ip address than your wireless nic. I suspect you either have the router not set to hand out ip addresses, the info it is handing out is wrong, or you may have a static ip set. Did you ever have the laptop working on the wired nic?

Try disabling the wireless connection, plug up the cat 5 cable, open a dos prompt and type;
ipconfig /all

Notice the information. Now unplug the cable, enable the wireless connection and do the same for the wireless nic. The ip address should be different, but everything else should be the same. Let me know what you find.
