Wireless not working on dell laptop, it is working on other laptops . It works when it is wired

There is a strong chance that the wireless card inside is bad. I work at a computer repair shop and work mainly with laptops. It isn't uncommon for wireless cards to go bad, before their "time". Usually Dell's have access panels on the bottom of the laptop where you can see the wireless card. It will have 2, sometimes 3 small wires plugged into it. Usually dell' use Dell brand cards, which are really repackaged Broadcom wireless cards in most cases. In your situation, write down what the model number is, go to another computer, look up that model on ebay, buy one, replace it.

Hi,
you can do a quick troubleshooting on the laptop.
1. used another network cable and check that no pins are broken on the laptop.
2. go to device manager and remove the network adapter and reinstall it.

if this don't work. if you have a wireless router, you can connect to the internet over the wireless network adapter on the laptop.

good luck!!

hi there...
1: goto Control Panel > Network and Sharing Center > check the Status it should be like this under Activity http://oi56.tinypic.com/ims8cz.jpg if it has a cross X on it ,then click on Diagnose it will tell you what is the issue.. 2: Download newer SP of your Operation System can also resolve the issue.

If you have connected your net to desktop with wire then simply remove wire from desktop and attache it with laptop......if you have wireless router then there is no need to replace wire.....just turn the wireless on in laptop....both will work simultaneously...

Don't wait tell you laptop is defective, at least buy a new wireless lan before its too late.

You have not mentione the issue. You have just posted that everything is allright and working.

Check what is the ipaddress,tried to shut down the laptop and drain flea power.Then check if the laptop can detect wireless connection. Then ping website in command prompt.Try ipconfig /release and then ipconfig /renew. Try connecting wired internet connection to check if issue with operating system or browser or wireless connectivity.

try gettin a disc what is got the internet on or a wire think

you will find that at support.dell.com enter model number and operating system and that should do it.

find the manufacturer/model # of your wireless adapter and download the latest driver from dell's website (you can go to support.dell.com and enter your service tag/laptop model # if you want).
