Can't enable Dell Wireless 1390 WLAN Mini-Card

"The radio of your wireless adapter is not currently turned on. Please press the Cancel button and turn the adapter's radio on."


I press cancel.



I check the "Enable Radio" box in the Dell Wireless WLAN Card Utility.



I press "Apply."



I get the error -- "The Dell Wireless WLAN Card is still disabled. Slide the Wireless ON/OFF switch to enable it or press Fn-F2 to enable it."



Pressing FN-F2 does not fix the problem, and I don't think there is a manual switch.



Suggestions?

    The green light is not on. FN + F2 does not make it turn on/off for me.
    It is installed in device manager. It doesn't appear with an exclamation mark. I have taken the card out and put it back in. I have uninstalled and install with updated drivers. I think I need to replace the card...

    There is a light above the keyboard, second from the right that shows green if the wireless is turned on. Holding FN+F2 does toggle the on. then off. DO you see a light go on them off when you use these keys? Have yoiu checked Device Manager to see if the WLAN has the driver installed? If it does not appear on the list, or appears with an exclamation mark,

I had the exact same problem and went through the same steps that he did. It was only when I searched for a physical wireless switch (on the left side of my Dell D630) that the problem was solved. I didn't even know it was there and must have inadvertently knocked into the off position.

I was using the wireless network, disabled the radio and after reboot was unable to get it to save the enable click. After reviewing all software options listed here - checked wireless adapter setting in BIOS - it was turned off! Turned this on in BIOS and upon boot was able to access wireless network again. Hope this helps you.

Look on the right or left-hand side of the laptop, you'll see the switch. It's got the wireless symbol ((i)) next to it, and if you can see red next to the slider switch, it's OFF. Slide it the other way to ON and the red disappears. Problem solved, you won't get the error message again, and you should be able to connect to your wireless network. Most people don't even know about that switch until it slides to OFF by mistake, like while you're carrying the laptop around or something.
Or, if that doesn't solve it and you have an Inspiron 1545, try pressing the F2 key (without the Fn key) if it has what looks like the wireless symbol ((i)) on it. Normally you would hold down the Fn key at the same time to enable the "function" of the F2 key, but for some reason Dell reversed the function keys so that what WOULD have been Fn+F2 on older models is now just F2 on its own (without the Fn key).

For those with a manual switch, use the switch to enable the radio feature.

for others without the physical radio switch, first try fn+f2 or Ctrl+f2. If that doesn't work, re-install the device driver for the wireless cards and then try it (fn+f2 or Ctrl+f2)

I just read through the replies to this and looked on the left side front of my Dell Vostro 2510 and found a manual switch. This fixed my problem.

I had this problem; checked to see if Wireless was off in BIOS.

Nothing I did worked, including pushing the fn+f2 key. So I checked if the wirelesses was off in the BIOS. there is also a option for what the wireless switch will do; I picked the option for it to do noithing (think the actual option was "none)

Rebooted and bam, my radio was on!

According to the manual there is no hardware switch. This issue is either driver related or software related.
You can try going inot the Device manager:
1. Right click My Computer
2. Choose Manage
3. Select Device Manager

Then uninstall the WLAN device and reboot.

I am not sure about Dell Laptop. But in most of the laptops there is switch to enable/disable wireless. Please check your manual. (Mostly it should be on any of the four sides and not at the bottom of the laptop)

Dell Wireless 1390 WLAN Mini-Card driver


Hi. You can download the driver from Dell website. I strongly recommend that even there will be more recent versions out there, stay with the versions released by Dell, Dell before releasing a driver tests it with the systems to ensure full compatibility and zero-problems with other devices:

Dell Wireless 1390 WLAN mini-card driver

Also for future needs, it's advisable that you go to the following web page:

And enter the service tag of your Dell computer, so that you could get drivers specific to your system.

How do you turn on wifi for dell latitude d610


There is not wireless switch on this model. To turn on your wireless you will need to hold down FN + F2. If this does not turn on your wireless its most probably disabled in the Bios. To enable it, press the F2 key at the Dell Logo on startup, move down to wireless, press enter and move to wireless control, make sure its set to Fn+F2/App, then move down to wireless devices and make sure it set to on. Press Esc, and save changes and exit.

Wireless card in E1505 Dell not finding networks in range


The 1390 WLAN Minicard may not be configured to communicate with your wireless router.
Check the wireless router settings, (check the wireless settings on your other computer) and configure the 1390 WLAN with the same settings eg. SSID, WEP/WAP encryption, etc.
Is MAC address filtering enabled on your wireless router, if so add the MAC address of the 1390 WLAN to the MAC address list in the wireless router.

Check the TCP/IP properties of the 1390 WLAN card the Internet protocol should not have a fixed IP address, set it to Obtain an IP address automatically including the DNS.

Use the Ipconfig command to see the IP configuration of the network cards.

Use the Ping command to see if you can communicate with wireless router.

Internal wireless card has been disabled. How do you fix this?


Hi car7924,

First, make sure that the wireless switch on the left side of the computer is turned on (this should make the WIFI light go on -- beneath the lower right corner of the screen). If it doesn't work, then try going to Start Menu > Control Panel > Network and Internet Connections > Network Connections.

You should see the Wireless Network Adapter in the window that comes up. If you don't, you need to download the driver for that adapter. The most common adapter in the D820 is the Dell 1390 WLAN MiniCard, and the driver for it can be downloaded at the following web address:

http://drivers.softpedia.com/get/Other-DRIVERS-TOOLS/Others/Dell-Latitude-D530-Wireless-1390-WLAN-MiniCard-Driver-A17.shtml

If, on the other hand, you do see the Wireless Network Adapter, but it says "Disabled" underneath the name, then right-click it and select "Enable." This should make it work.

I hope this helps - please let me know if I can be of any further assistance.

Kind regards,
H2H
