    there should be only one network card or buildin network connection. unless the machine is a server, even with that, dual network card is very difficult to configure.

    if you have 2 network card, try to remove one.

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.
    Router
    Address
    Username
    Password
    3Com
    http://192.168.1.1

    Netgear
    http://192.168.0.1
    admin
    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 resolve "Limited Or No Connectivity Errors" in Windows


When attempting to set up or make network connections on a Windows computer, you may encounter a Limited Or No Connectivity error message similar to the following:
Limited or no connectivity: The connection has limited or no connectivity. You might be unable to access the Internet or some network resources.

This message can result from any of several different technical glitches or configuration problems. Follow these steps to resolve Limited Or No Connectivity errors in Windows.
1. Determine whether your network access is functioning properly (that you can reach local network resources and the Internet). If you are using a broadband Internet and Windows XP Service Pack 2, this message is often a false error report. See Microsoft Knowledge Base article 892896 for details on how to work around this error appropriately.
2. If your network access is non-functional. continue to the following steps.
3. If your computer connects to the network through a broadband router , resetting (powering off and on) the router may resolve the issue. If not using a broadband router, or if resetting your router only temporarily resolves the issue and the error message re-appears later, continue to the following steps.
If connecting to your network using Wi-Fi and using wireless security, your WEP or other security key may not be set properly. Check the wireless security configuration on your computer's network adapter and update if it necessary.
4. If connecting to your network using an Ethernet cable, your cable may have failed. Temporarily replace your network cable with a new one to determine whether this resolves the issue.
5. If using a broadband router and DHCP on your network, check your computer's IP address to verify it is valid and not a private address that starts with 169.254. An invalid address of the form 169.254.x.x signifies your computer's inability to obtain a usable IP address from your router.
To resolve DHCP configuration problems, proceed to the following steps.
6. Reboot your computer, router (if present) and broadband modem together, then re-test your connection.
7. If your connection remains non-functional, run the Windows Network Repair utility on your computer.
8. If your connection remains non-functional, update your router settings to change from dynamic to static IP address configuration, and set an IP address on the computer appropriately.
9. If your connection remains non-functional, unplug your router and connect the computer directly to your broadband modem. If this configuration is functional, contact the manufacturer of your router for additional support.
10. If your computer is connecting to your network directly through a broadband modem, or if your Internet access remains non-functional after following the instructions above, contact your Internet provider for support.

Network Driver Issue/Internet Connection issue


you can try a couple of things, on the back of the router is a small reset button, you will need a pen or pencil to push this button, hold it in for 10 sec. or so, until the router resets, and try to connect then, or unplug router, leave off for 10-15 sec. plug back in and wait fir it to reset this way, or a more involved way is to go to your DOS or command prompt window, type in this as follows

ipconfig /release

(wait a few seconds for this to do its thing)

ipconfig /renew
(if this doesnt work ask your parents if they put a block on the router)

Keep getting message that cable has been disconnected..


First off, you need to update Windows.Go to where your modem is, unplug the ethernet cable from the router and connect direct to your computer, and run Windows update. You may have to reboot several times before all the updates have been implemented.

Then, the flag message you have been getting "cable disconnected" indicates to me that the flag is coming from the internal network card of your computer, not the wireless client in the computer. You need to make sure the wireless client is setup properly to see the router.

Do you know if security has been setup on the router? If so, we will need to walk down that road to get it set up on your laptop.

But first things first. Get the computer updated, and reply back answers tot he above, as well as what Operating System,s you are running.

My network says that it can't find the internal wireless adapter


You may have to reboot your PC and try to connect again.
If you have "Viewed all available networks" and tried to connect to your Wireless network but cannot what kind of error message are you getting ?

To quickly find out if you have Internet Connectivity coming in at all from your Internet Service Provider turn off your wireless switch on your laptop and try to connect a cat5 directly from your PC ( connect cat5 cable to what looks like a slightly larger telephone jack on the side or back of your laptop) to the back of your router and see if you browse the internet. You may have to reset your router (unplug and plug)

Make sure your wireless is on, disable WEP on the router and see if you can connect, if you can try againwith WEP. If this fails try and use the hex key instead of the WEP password set up on the router. Also make sure that your router is doing DHCP over WEP or you won't be able to resolve web pages even if you are properly connected to the Internet.

Wireless network card in PC loses connection


The best reccomendation I might make is to stop using the manufacturer's proprietary management software. Use Windows' own built in wireless management. You can select this by selecting the network adapter in the 'network connections' control panel and checking the box that says 'let windows manage this device' That should fix the problem. Also, try getting the most recent updates for both windows and the network adapter.
