Connectivity wireless network connection2 always has limited or no connectivity have tried moving every plugs to no avail.

Desktop computers are not known for their wireless connectivity, but it is possible to make yours one that is.

Wireless network adapters, which enable your desktop to pick up wireless Internet signals, come in a variety of forms, and are all fairly easy to install.

Once you have one installed, getting online wirelessly is almost effortless.

Choose the network adapter that is right for you.

The easiest network adapters to connect do so via USB, but if you have limited USB ports on your desktop, you may want to try another option.

There are also network adapters that plug into your Ethernet port, but if you want to use that port for a landline connection you have, and wireless is your backup, then this also may not work for you.

If that is the case, you can buy an add-in card, which fortunately for Dell owners is very easy to install.

Dell computers are designed to be opened and have add-in cards installed without the use of screwdrivers; check your manual for details.

Install the network adapter and any included software.

The adapter will usually come with a software CD with a notice to run the CD either before or after you have plugged in or installed your adapter.

Go through the setup steps on the CD, click "Finish" when it is complete, and your wireless network adapter should then be activated and ready to receive wireless signals.

Click the notification that pops up letting you know that wireless networks are available; or, if there is no notification, go "Start > Connect To" and all available networks will be displayed.

Double-click on the logo for the network you want to connect to and enter the security key if it is a secure network.

(If you set the network up, you should have the security key saved somewhere with your network settings.

If you are connecting to a nearby hotspot, you will need to ask the permission of whoever set up the connection and obtain the security key from that person.)

Select "Home," "Work" or "Public Location" when prompted to designate what type of network connection this is.

You will then be asked if you want your computer to remember this computer and start it automatically in the future.

If you plan to use this connection regularly, it is a good choice to check the boxes next to both options so that the connection will always be available and you won't have to enter a security key for it again.

Hope this helps.

Try power cycling your router while your computer is connected via wireless (even with limited or no connectivity) . Unplug the router for 15 seconds and then plug it in again. Hopefully the router will assign your computer a new IP address.

have you tried rebooting it?

Try going to Network and Sharing Center - Manage Network Connections. Click on the connection and enable it.
Also try Network and Sharing Center - Manage Wireless Connections, and moving the wireless connection you'd like to use and move it to the top of the list. Select any operations that will enable or connect to the network.

The settings on your wireless router may be the problem.
For example if you have many wireless cards connect to your router over time all of the available ip address may have been taken and your newest card cannot connect. In this example you would need to extend the range of available ip addresses available.

Try to go to start -> settings -> network connections -> and see if your connection is working properly if there is a problem it will say it's limited. If limited try right click and repair, if it won't work try right click on connection then properties and in ip/dns section set all on automatic. 

If none of this will work try to disable firewall for few min and see if it works, to do so go to control panel Windows Firewall,

If password would be wrong you wouldn't be able to connect at all, you can always try to go to available wireless networks and try to disconnect your connection and then reconnect again it should prompt for pass.  

Limited or No Connectivity on Windows XP

Limited or no connectivity indicates that the computer cannot acquire a valid IP address. This is due to incorrect network key you have entered. We need to check the correct WEP key in your router's setup page. Here are the troubleshooting steps we recommend you try:

Note: You need to use a computer hardwired to the router to check the wireless settings.

1. Please open any web browser like Internet Explorer or Netscape Navigator.
2. Connect to the router by typing http://routerlogin.com/basicsetting.htm or http://192.168.1.1 in the address field. Please click Enter or Return key.
3. A window will prompt for a user name and password. The default username is "admin" and the default password is "password".

Note: If it does not take password as the password, you might have changed it when you have run the NETGEAR Setup CD so please try other passwords. If you cannot remember the password, you need to reset the router and run the Setup CD to reconfigure it.

4. Click on Wireless Settings under Setup page.
5. Take note of the SSID.
6. Scroll down, look for the Security Options and check whether WEP (Wired Equivalent Privacy) or WPA (Wi-fi Protected Access) is selected.
7. If its WEP is enabled, copy the value of the selected Key number. If WPA is selected, take note of the Passphrase.
8. To configure the computer with wireless adapter, please consider the following:

Configuring the NETGEAR adapter and Saving the Profile

a. Open the NETGEAR Smart Wireless Settings Utility icon located at the lower right portion of your computer screen. It will then open the Settings tab.
b. Change the Network Name SSID to match the one on your router.

Tip: As an alternative to typing in the SSID, you can use the Network tab to view the available wireless networks. Double click on the desired network.

c. Click the Apply button to activate the connection.
d. Enter a name for your profile (e.g. NETGEAR to Home Network) and click the Save Profile button to store the current settings.

Note: The above procedure applies only if you are trying to connect to a wireless network with no wireless security.

If the computer is using Windows built-in wireless program to manage the wireless adapter, please follow the steps below:

For Windows XP Service Pack 1

a. Please right click on the Wireless icon on the right lower end portion of your computer. Then click on to View Available Wireless Networks.
b. Click on the Advanced tab.
c. Please delete all the preferred networks then click on OK.
d. Right click on the Wireless icon again and click on View Available Wireless Network.
e. Please select your network and click on Connect. If you have Wired Equivalent Privacy (WEP) or Wi-fi Protected Access (WPA) enabled on the router, it will ask you for the network key. The network key will be the Key or Passphrase you have copied from the router setup (refer to step 7). Please type in the Network Key and then confirm it.
f. Make sure not to enable IEEE and then click on Connect.

For Windows XP Service Pack 2:

a. Please right click on the Wireless icon on the right lower end portion of your computer. Then click on to View Available Wireless Networks.
2. Click on the Change Advanced Settings.
3. Click on the Wireless Networks tab remove all the preferred networks then click on OK.
4. Right click on the Wireless icon then click on View Available Wireless Network.
5. Select your network and click on Connect. If you have Wired Equivalent Privacy (WEP) or Wi-fi Protected Access (WPA) enabled on the router, it will ask you for the network key. The network key will be the Key or Passphrase you have copied from the router setup (refer to step 7). Type in the network key and confirm it. Then click on Connect.

Note: You may use the wireless utility of your wireless adapter in connecting to the wireless network but you need to clear "Use windows to configure my wireless networks" on the Wireless Networks tab. Please ask assistance from the wireless adapter vendor for configuration if using a proprietary wireless utility (non-NETGEAR wireless adapters).

why, tell me ur problem briefly.........

Mine always does that when my IP address lease renews but it's an easy fix. You can usually click on the pop up that says limited or no connectivity then in the box that comes up click repair. If you cannot get to that box you can just go to start>control panel>network connections then right click the wireless network connection then left click repair. That usually works for me.
Hope that helps!
