PROBLEM WITH NETWORK DRIVER

There are several possible reasons to have a connection fail. You could have a driver issue, the network adapter may have failed, the passkey/SSID aren't correct (for wireless connections) or the router/WAN network is down. (The WAN being disconnected happens with my systems at regular intervals.) If the router/access point has been secured to limit the number of devices on the network or only allow certain MAC addresses, use a different device to log in to that router and increase the number of allowed devices. (This will depend on the make/model of your router. It's probably under the Advanced settings.)

What type of hardware are you using (laptop/desktop/tablet)? What make and model is it? If you have both wired and wireless network adapters, try making a new network with the other adapter. Also try to create a new network connection for the current adapter.

You can check for driver issues from the desktop clicking the Windows key + X (on systems with keyboards) and choosing the Control Panel. Then under System and Security (or Hardware and Sound) choose the Device Manager. Scroll down to the Network Adapters and expand that section by clicking on the plus sign. If there is a triangle with an exclamation point or a red x, then you have a driver issue. Use another machine to download the drivers and place them on a USB drive or other external media. Install the drivers. (If you can use a different network adapter, then just download and install the drivers.) Try the network trouble-shooter to identify a problem.

If updating the drivers doesn't work, check if other devices do connect to your network. If another device works, try a USB network adapter (or for a desktop, a PCI/PCI-e network card). You may need to disable the on-board network adapter in the BIOS. (This is hardware dependent again.) If other devices can't access the network, try directly connecting a wired network to your DSL, FIOS, or cable modem. If the direct connection doesn't work, then contact your provider. If the direct connection works, try a new router/access point.

I hope this helps.

(note: on an older XP laptop with only USB 1.0 ports, I recommend replacing the device, instead of a USB network adapter. The USB port speed will make the network connection excessively slow.)

you lost your PC drivers, You must find driver for network adapter for windows7, after install it apdate you drivers for windows 7 from toshiba.com

let me tell you its very easy.

Follow these steps to connect your Linksys adapter to available wireless connection:-

1.With this adapter you must have received a disk of driver for this adapter.
so install the drivers disk first.

2.Once the driver disk install then now you can search for available wireless network name.

Download the driver from another computer that's connected to the Internet onto a USB flash drive. Transfer the file to the computer without the network driver. If you have a disc with the drivers, then just reload that. If not and since you can't connect to the Internet to download the driver, you need a USB flash drive.

You have to connect to your network without using wireless then u have to go to the linksys website and download the windows 7 driver. Install that driver then u can connect with wireless. Worked for me! Gl.

Have you installed tnhe drivers for your Network Adapter? Without the drivers the adapter is, as far as the computer knows, not there. Did you get a disk with your computer and/or adapter? If so install the drivers and problem should be solved.

You need to Update the Drivers for your Wireless Adapter...Download the Drivers from here

After downloading the drivers you need to unzip the file...After you unzip the file you should un-install the adapter drivers/software from Programs menu...Leave the adapter connected to the PC and reboot your computer...Once the computer is rebooted you should see a message "Found new Hardware"...Select the option Install it from a specific location and click Next, then select Include this location in Search and browse to the place where you have unzipped all the files and select the Driver folder and click O.k...Then click Next and it should install the adapter drivers...

NOTE : This installation doesn't install the software(Linksys Monitor)...

Once the Adapter is installed, Click on the Start button >>> Control Panel >>> Network Connections- Right click on the "Wireless Network Connection" icon and select "View Available Wireless Networks"- If you see your wireless network in the list, highlight it by 'single' clicking on it- Now click on the 'Connect' button below- If your wireless network is secured, it would ask you to provide the network key- Provide the wireless network key and confirm it again in the confirmation box and click "Connect"...It should connect to your Network and Internet...

go to dell.com, under support you can put in either your service tag number or model number and then you will be able to download not only the network adapter driver, but all the drivers you need.

i) Click on Start button ---->Select option Control Panel------>Select Network Connections----->
  a new window appears showing the "internet connections icon " Such as:

  Local Area Connection 1 or 2 or 3 and since you are not connected it will show this icon as:

eg1:  Local Area Connection 1 or 2 or 3
        Network Cable Unplugged, Firewalled
        VIA compatible Fast Ethernet  

        in this case u can download VIA network drivers....from internet..


                      or 

       eg2: Local Area Connection 1 or 2 or 3
       Network Cable Unplugged, Firewalled
       Realtek RTL8139 Family Fast Ethernet NIC

       in this u can download "Realtek RTL8139" network drivers.... from internet(which is showing              model no: RTL8139 through google search engine )


                                         (OR)


ii)        Click Start button ---->Select RUN option ----> type in the text box devmgmt.msc --->Select                Network Adapters....

           but this will show wheter ur network adapter or NIC is VIA or Realtek or......but does show the             correct Model NO: of VIA or Realtek....
  
            so i would suggest to follow the step (i)
