Check if the wireless switch is present or not present.
Manually Enable the Wireless Adapter if present
Check the side of the notebook computer for a sliding switch.
Wireless Switch in the On Position
First you turn off the system flip it upside down then locate the battery and take the battery out and make sure you disconnect the ac adapter,.

I have replaced my dell inspiron 6400 screen cover. Now my wifi connection does not work. I am getting a message "no wifi networks found". Manual diagnostics tool shows "scan test"...

1st : check if the wireless capability of your notebook is enabled. There might be a switch or button that needs to be pressed to enable the wireless capabilty of your notebook.

2nd : check the device manager if the wireless network card is listed with no question mark or exclamation point. if it has, then reinstall the driver.

3nd or the wireless card might loosen.. at the bottom of your notebook, you will find several screws there. look for a small box usually with 2 screws. Open that up and you should see a black and white cable connected to a small card. Ensure those 2 cables are connected. Ensure that the laptop is powered off when you do this. Then try it again.

Hope that works.

I have reloaded XP on my 6 year old Dell Inspiron 500m and it appears to have forgotton it has a built in wireless adaptor. The wireless network icon only shows in the 'my connections' display when I...

For starters, make sure the wireless adapter is turned on. Some laptops have an external switch. Also, look to see adapter is enabled in the Device Manager (control panel > system). If you do not see an device manager, you may need to reinstall driver for the adapter. All drivers that came with system can be found online at Dell's support website.

I'm trying to set up a new wireless router but i get a messagw that says thw network adapter is not working

Open the Device Manager and check if the wireless device is listed under the "Network Adaptor".

You may also check in the "System Information" window for all the network adaptors installed and functional in the Computer.

Follow the steps given below to access the "System Information" window:

(i) Please press the Windows key on the Keyboard and then press the "R" key while holding down the Windows key to open the Run dialog box.

(ii) Then, please type "msinfo32" in the Run dialog box and click OK to open the System Information window.

(iii) In the left pane, click on the plus sign next to the Components then on the Network adaptors. This will display all the installed and functional network adaptors in the right pane. Check if wireless adaptor is listed.

If the wireless adaptor is not listed at any of the places then you may try restarting the Computer and reinstalling the wireless driver.

If the Computer still shows the message then the issue may be with the wireless adaptor.

Not sure I understand you what you mean. Let me recap:
1) Your LAN adaptor was working before you reloaded Windows XP Pro.
2) Now it’s not showing up in “Device Manager”.
If this is the case, there must be some software driver missing. Make sure there are no other devices that have an error. Double check Dell’s website at and select "I'm looking for drivers and downloads". If you don't have the proper version of Adobe you will be prompted to install it. Once installed return to "drivers and downloads" and enter the "service tag", (serial number) of the laptop. Dell keeps a listing of drivers for every customer's computer they sell.

Your responses are intended to improve the level of service provided. Please show your appreciation by rating your experience.
Thank You.
