Question about Dell Inspiron 1420 (dndwja2_5) Intel Core 2 Duo T7250 (2MB cache/2.0GHz/800Mhz FSB) 250GB/1000MB PC Notebook

2 Answers

Dell Inspiron 1420 Wireless adapter is not working; I had the wireless network perfectly fine a while ago and now that I wanted to use it again, won't let me. The light of the wireless switch is not ON when is supposed to be ON, what happens is that whenever I move the wireless adapter's switch the Bluetooth goes on an off, and the connection status says: "The dependency service or group failed to start". I went to Services and tried to Start the WLAN AutoConfig service manually and didn't work showing an error 1747: The authentication service is unknown. I'm in the point whether to think that the minicard is not working or that the minicard is not being powered, if so How can I fix it?

    Hello, I already did that and nothing yet. I'm going to try and restore the computer from my last log in, and see what happens. Do you know a way to test if the card is good? besides moving the switch, maybe taking the card out.

OK ..if you use a external card ..you need a driver to install for it ...and after that make the settings ..
But ..assuming that you etalking about the laptop's internal wireless card ..the following steps must be done ..
First ..you have to make sure that you turned on the wifi card from the button ..
than if you have it on ..go to device manager by right click on the my computer and choose properties...than hardware ..than device manager ,,
In there look under the network and see if the card is present and not in yellow with ask sign on it ..If it is like that it means that you need the driver and reinstall it ..
If it is not present at all in the network area..it means it is disabled..and in this case..the first step is to right click on the network are a..and choose scan for hardware changes..This will scan the devices and if it is the case will get your card visible again ...Right click and enable it ..and also run the update driver ..to reinstall it ..
if there seam not to be a driver available in your system ..get on the support site and download the wireless driver for your operation system and run it again ..
Here is the link ..

Usually this kinda issue is caused by the lack of driver in the system ..and after installing it things will be ok
IN the last resort you have to get into BIOS settings by pressing F2 on start up ...and once in there look for a feature called optimal factory defaults(settings) and engage it ...Save the changes in bios settings by pressing F10 and restart ..
This will enable the card if it is disabled for some reason ...and if you want you can start with this operation in the first place ..cause if it has no driver ..after doing this it will ask for it automatically ..

Welcome to Fixya

You might need to reinstall the driver of the wireless network card first since everything is working a while ago. Restart the computer after reinstalling the driver. Power cycle the router also to refresh the connectivity.

Please reply this email for any update.

Thank you for using Fixya!

I have a Dell Inspiron Laptop. I recently reformatted it. Now It does not recognize wireless connections. I cant connect to the net Can anyone help?


When you reinstalled Windows, Windows probably did not include a driver for your wireless adapter. A driver tells Windows how to interface with a certain device, such as a wireless adapter. You can easily download the driver online and install it. Once installed, restart the computer and you should again have the ability to connect to wireless networks.
I've gone to the Dell website for you and found the correct driver. Please visit this link: http://support.dell.com/support/downloads/driverslist.aspx?os=WLH&catid=5&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=INS_PNT_PM_1525&hidos=WLH&hidlang=en&TabIndex=&scanSupported=False&scanConsent=False
On that website, I would first try downloading the first driver on the list. If that doesn't enable your wireless after a reboot, try the other ones. After the correct driver is installed, your wireless will be working again.

I have a Dell Inspiron 1420 that has a Microsoft Windows Error message that will not go away even when closed. It says "Dell Wireless WLAN Card Wireless Network Controller stopped working and was closed"....


Try Deleting the wireless card from Device Manager.

Beware though, if you do this all your wireless settings, such as network names and keys,will probably be deleted as well.

Then right click on the name of your computer and click scan for changes and that will then reinstall the card. Can't say it will help but it's woth a shot.

Network and audio devices not working


It sounds like you may have either a faulty motherboard or a problem with the drivers. I would first try reloading the drivers by downloading the latest ones from the Dell support site.
Let me know if this helps. If not we can try some other things.
Thanks.
