Question about HP Pavilion dv1000 Notebook

NIC hardware failure

Everything was working fine, then poof.....Network cable is unplugged error message. Swapped router ports, swapped network cables, everything points to the NIC. Is the NIC on this device integrated into the motherboard? If so, am I better off investing in a wireless router vs sending this laptop in for repair?

    The exact model is the DV1040US. I have bypassed the problem by purchasing a D-Link PCMIA card with a RJ-45 jack. ($20)Seems a little slower, but it is functional. Still curious if the NIC is integrated to the motherboard though.

Maybe your problem is software related. Maybe a virus changed some settings. I would check all the internet settings and the network card settings. I've seen this happen before. In windows xp click Start/Control Panel/Network Connections. Then right click on your local area connection and Click Properties. Slide the bar down to the TCPIP protocol and highlight it, then click Properties. Make sure you are obtaining the IP Address and DSN Server address automatically. Click the Advanced button and make sure DHCP is enabled.

Can not connect to my wireless router


1. Choose your wireless equipment The first step is to make sure that you have the equipment you need. As you're looking for products in stores or on the Internet, you might notice that you can choose equipment that supports three different wireless networking technologies: 802.11a, 802.11b, and 802.11g. We recommend 802.11g, because it offers excellent performance and is compatible with almost everything.
Shopping list
  • Broadband Internet connection
  • Wireless router
  • A computer with built-in wireless networking support or a wireless network adapter
A wireless router
The router converts the signals coming across your Internet connection into a wireless broadcast, sort of like a cordless phone base station. Be sure to get a wireless router, and not a wireless access point.
A wireless network adapter
Network adapters wirelessly connect your computer to your wireless router. If you have a newer computer you may already have wireless capabilities built in. If this is the case, then you will not need a wireless network adapter. If you need to purchase an adapter for a desktop computer, buy a USB wireless network adapter. If you have a laptop, buy a PC card-based network adapter. Make sure that you have one adapter for every computer on your network.
Note: To make setup easy, choose a network adapter made by the same vendor that made your wireless router. For example, if you find a good price on a Linksys router, choose a Linksys network adapter to go with it. To make shopping even easier, buy a bundle, such as those available from D-Link, Netgear, Linksys, Microsoft, and Buffalo. If you have a desktop computer, make sure that you have an available USB port to plug the wireless network adapter into. If you don't have any open USB ports, buy a hub to add additional ports.
2. Connect your wireless router Since you'll be temporarily disconnected from the Internet, print these instructions before you go any further.
First, locate your cable modem or DSL modem and unplug it to turn it off.
Next, connect your wireless router to your modem. Your modem should stay connected directly to the Internet. Later, after you've hooked everything up, your computer will wirelessly connect to your router, and the router will send communications through your modem to the Internet.

  • If you currently have your computer connected directly to your modem: Unplug the network cable from the back of your computer, and plug it into the port labeled Internet, WAN, or WLAN on the back of your router.
  • If you do not currently have a computer connected to the Internet: Plug one end of a network cable (included with your router) into your modem, and plug the other end of the network cable into the Internet, WAN, or WLAN port on your wireless router.
  • If you currently have your computer connected to a router: Unplug the network cable connected to the Internet, WAN, or WLAN port from your current router, and plug this end of the cable into the Internet, WAN, or WLAN port on your wireless router. Then, unplug any other network cables, and plug them into the available ports on your wireless router. You no longer need your original router, because your new wireless router replaces it.
  • 3. Configure your wireless router
  • Using the network cable that came with your wireless router, you should temporarily connect your computer to one of the open network ports on your wireless router (any port that isn't labeled Internet, WAN, or WLAN). If you need to, turn your computer on. It should automatically connect to your router.
    Next, open Internet Explorer and type in the address to configure your router.
    You might be prompted for a password. The address and password you use will vary depending on what type of router you have, so refer to the instructions included with your router.
    As a quick reference, this table shows the default addresses, usernames, and passwords for some common router manufacturers.

    password

    Internet Explorer will show your router's configuration page. Most of the default settings should be fine, but you should configure three things:
    1. Your wireless network name, known as the SSID. This name identifies your network. You should choose something unique that none of your neighbors will be using.
    2. Wireless encryption (WEP) or Wi-Fi Protected Access (WPA), which help protect your wireless network. For most routers, you will provide a passphrase that your router uses to generate several keys. Make sure your passphrase is unique and long (you don't need to memorize it).
    3. Your administrative password, which controls your wireless network. Just like any other password, it should not be a word that you can find in the dictionary, and it should be a combination of letters, numbers, and symbols. Be sure you can remember this password, because you'll need it if you ever have to change your router's settings.
    The exact steps you follow to configure these settings will vary depending on the type of router you have. After each configuration setting, be sure to click Save Settings, Apply, or OK to save your changes.
    Now, you should disconnect the network cable from your computer.
    4. Connect your computers to the wireless network If your computer does not have wireless network support built in, plug your network adapter into your USB port, and place the antenna on top of your computer (in the case of a desktop computer), or insert the network adapter into an empty PC card slot (in the case of a laptop). Windows will automatically detect the new adapter, and may prompt you to insert the CD that came with your adapter. The on-screen instructions will guide you through the configuration process.

How to Troubleshooting Network




Here you will learn network troubleshooting tips, fix tcp/ip errors, tcp/ip settings, internet connectivity errors, how to fix pc errors, lan connectivity issues, traceroute and ping commands. Whether your operating system is Windows or Linux network problems are likely to arise. Many times the network problems arisee due to improperly configured TCP/IP settings. Following is the basic checklist to identify and troubleshoot the basic networking errors.
1. First of all you should learn what stopped working server or client computer also see if the outage affecting the other computers or only one.
2. If you server stopped working you should inform the users of the server and you should start working on fixing the error.
3. If a single client computer stopped working or disconnected from the network, ask the user of that computer that what recent changes cause the server to stop working such as newly installed software or games, service packs, internet software, new hardware or any other thing.
4. Check the physical network connectivity. The most network problems arise due to the physical layers failure.
5. Check all the network cable connections. You can start at the NIC and check if the green light is blinking then check the hub and see if the computer is getting the link across the cable.
6. Get a cable tester to check the connectivity of the cables.
7. Finally start pinging the network both Windows and Linux have the PING command. You can use ping command in this way start > Run > cmd > type "ping" then IP address of the other computer

Dell Inspiron 1501 10/100 network port not working. I have installed driver and have known good cable in port. Worked until 2 weeks ago. Lights don't blink, onboard LAN turned on in BIOS.


Sounds like a failed NIC.

Things to try:
  1. Flash the BIOS to current version if not already done.
  2. Reset BIOS Defaults
  3. If NIC still doesn't work, try a system restore to a time when it worked.
  4. If that fails, most likely a hardware failure.

Dell E6400 onboard NIC cannot get network connection - "A Cable Is Unplugged". The laptop is undocked with CAT5 cable firmly attached.


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.

Can not connect wirelessly with router


The list of wireless routers that are available in Windows is very limited and the signal strength of any router that is detected is weak. This can occur when the Lite-On USB Wireless 802.11 b/g hardware and Windows are not able to fully synchronize the signal strength data. Figure 1: Example of detected wireless devices when the antenna cable wire is connected to secondary port c01153759.jpg Figure 2: Example of detected wireless devices in the same environment when the antenna cable wire is connected to primary port c01153760.jpg To correct this error , download and install Lite-On USB Wireless LAN Driver Update (sp35177) (in English) from the HP Web site. This update should only be applied if your PC has the Lit-On USB Wireless LAN adapter and is exhibiting the symptom. As a work-around, you can connect the wire that runs from the wireless antenna port to the primary port on the cord as follows: CAUTION: This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.
  1. Open the side panel.
  2. Find the wireless networking board by following the antenna wire connected to the wireless networking antenna port on the back of the computer. Figure 3: Wireless networking hardware c01153761.jpg 1 - Wireless network board 2 - Antenna wire 3 - Wireless networking antenna port
  3. Very carefully, disconnect the small wire from the board by gently pulling the end of the wire away from the board.
  4. Connect the wire to the other available port on the board. Figure 4: Available port c01153762.jpg
  5. Replace the side panel, connect the power cord, turn on the computer, and use the computer again to verify that wireless signal strengths have improved.

How do i have a usb port run a high speed device


The USB port in your computer is not the new high-speed USB 2.0 version, and when you plug a USB 2.0 device in you will get that message. Most USB devices will still work but not give best performance. Just close the message window.

The network cable unplugged message can be disabled through the network settings. Normally Windows is set to display that message when there is no network cable connected. You can just ignore the message.

Ibm think pad t30


Hi,

To my knowledge, your laptop (IBM ThinkPad X30 2672) does not have any built-in WiFi. It's modes of connection are IrDA, modem, Ethernet, USP, Firewire aside from the regular serial & parallel. This would indicate that if you are wireless you either have a USB dongle or PCMCIA card. Please post back with your WiFi brand/model and your Operating System. Further, please post back likewise your WiFi AP/Router brand/model.

The message "a network cable is unplugged" pertains to the absence of a lan cable connected to your Ethernet port.

Good luck, kind regards and will await your second post.

Ethernet not seeing network cable when plugged in


- If you have wireless card enabled, disable it to see if it fixes the issue. - Did you try a different cable that you know works for sure? -Go to the laptop manufacturer site and download the latest driver, it may help. -Try a different port on your router (if you have one), if you don't then check to see if the cable is secured. -reset your modem and router. -Are you using the correct cable type? make sure it is a straight-throug cable and not a cross-over cable.
