You may have a driver problem. First, simply try to set up a new wireless connection. If that doesn't work, try this.
While hardwired go to:
http://downloadcenter.intel.com/SearchResult.aspx?lang=eng
(just copy and paste into address bar of browser if necessary, or type it as one long string.
Under "products" choose "wireless networking". Under "Operating System", find your specific O.S.
Under "Download Type", choose "drivers". Then scroll down to find the drivers you need.
Download and install the driver package
If this doesn't work, repost with more information concerning the make, model of your computer, type of operating system, and be very specific. Give as much info as possible

Installation instructions:
Immediate Installation/Upgrade of Drivers on Local Machine
To install or update on this machine now, click 'Install Now' below or use standard OS installation methods

To Install or Update Later:
1. Click Start, Run and then browse to the directory where you extracted this archive.
2. Double click Setup.exe and click OK. Follow the on-screen instructions to complete the install.
3. Right Click on "My Network Places, Choose properties and finish configuring your network.

Manual installation:
1. Click the My Computer and choose Properties, From Hardware tab, choose Device Manager.
2. Right click on Network Adapters and choose scan for hardware changes.
3. The Plug and Play Wizard should pop up. Follow instructions but don't select an Intel adapter from the list. Click on Have Disk.
4. Enter the path to the directory where you extracted this archive and click OK. Then follow the instructions to install the drivers. When the adapter is added, it appears in the Network adapters list.
5. Click OK and then Close. If prompted, restart Windows.

Optional Manual Update
1. Click the My Computer and choose Properties, From Hardware tab, choose Device Manager.
2. Right click on the adapter you wish to update under Network Adapters and choose Properties.
3. From the Driver Tab of the pop up, click the Update button.
4. Enter the path to the directory where you extracted this archive and click OK.
5. Follow the on-screen instructions to update the drivers.

NOTE: If you are installing a driver in a computer with existing Intel adapters, be sure to update all adapters with the same new software. This will ensure that all adapters will function correctly.

Troubleshooting
-Make sure that you use the drivers from this archive.

- When updating base drivers, if PROSet was installed, PROSet needs to be updated also. If you have downloaded the minimum Web Pak, you will need to download the full Web Pak to obtain the updated PROSet files before being able to access the PROSet application.

-In your computer's BIOS settings, make sure "Plug and Play OS" is set to YES.

-Make sure the driver is loaded and the protocols are bound.

-Check the Windows* Event Viewer for error messages.

-If you are attaching to a NetWare* network, check your frame type and verify that NetWare client or server software has been installed.

-Test the adapter with the Intel PROSet advanced configuration utility or with the DOS diagnostic provided in the Tools Directory contained in this archive.

-Check with your LAN administrator - you may need to install supplemental networking software.

Intel(R) PROSet II
To start Intel PROSet II, double-click the Intel PROSet icon found either in the lower right hand corner of the screen or go to Start/Settings/Control Panel/Intel PROSET II. To run diagnostics, select the adapter and click the Diagnostics tab, then click Run Tests. For additional information, click Help in the Intel PROSet window.
If this doesn't help go here:
http://www.piriform.com/speccy
Download and install the software. This will tell you everything you need to know about your computing environment that you will need to know to repost the question and get a definitive answer.
Open Device Manager (Start > Control panel > Hardware > Device Manager), look for anything that has a ?, or a yellow triangle w/an exclamation mark ( ! ). Make note of it in your next post.
Good luck
If this helps you resolve your problem, please
consider giving me a rating of 4.It will help me
as well. Thank you.

Cannot stay connected to internet with wireless dell laptop for more than a minute


This will either be a driver glitch or a problem with the router or your internet provider. Start by uninstalling the wireless drivers from the device manager, then reboot. The machine will find the wireless and reinstall the drivers automatically. If this doesn't fix it, then you might want to call your internet provider and have them check out your router and connection.
