Dell laptop wifi not working:  There are several reasons why your dell laptop wifi wouldn’t work. For the sake of simplicity, we’ll assume that you’ve already tested the wireless network with another computer or device, that you know the WPA password. You’ve confirmed that the wireless network is not at fault, and you’re pretty sure that your Dell laptop’s wireless is what is broken. The first, and likely easiest to resolve is making sure that the wifi antenna is not turned off. Depending on the model of your computer, you might find a physical switch on the front edge. For instance, the Dell Vostro 1500 has a big button on the left side at the rear. However, most Dell laptops don’t have a physical switch. There is a way with a function key combination to turn on or off the wifi. While the computer is turned on and running, try to press the Function key (Fn) and F2 (usually just above the #2 and #3 keys).

This should toggle on or off the wifi. You should see an indication that the wifi has either turned on or off, and the computer will have to make some modifications, so be patient after pressing the Fn+F2 combination. Don’t press it again and again and again. Give it 30 seconds or so for it to start doing something. The next reason that your wifi isn’t working can be related to the configuration of the wifi device. Most versions of Windows have the ability to repair the wifi. You can generally get to this by right-clicking the wifi icon (near the clock) and choosing “repair”. This will go through several diagnostic steps and will attempt to connect to the wifi for you. While you could manually disable and re-enable the driver, dis-associate and re-associate with the wireless access point and release/renew your DHCP wireless address, the “repair” feature does all of these things for you, so you might as well give it a try. If all of this doesn’t work, your next step is to get replacement drivers for the wifi network adapter. Go to support.dell.com and get the most recent drivers. That will likely fix the issue. Finally, there’s always the possibility that the wifi card in your computer is fried. You can replace it with an exact match, but it might be easier to get a USB wifi adapter from a local computer or office supply store.
