I just recently put a new power jack in my laptop.
Everything worked fine except for now my wireless does not work.
I have a Dell Latitude D620 laptop. I keep getting an error that says the radio is disabled.
I try to enable it and it does not save the setting. It reverts back to disabled.
The FN - F2 keys do not turn the wireless on. It does nothing.
The wireless switch on the side seems to be very loose and the LED does not light up.
I've went into the wireless utility to enable it and I still get the error that says it is disabled.
It is recognized in my device manager and it says it is working properly.

I'm game for taking the whole thing apart again....I just don't know what to do from this point.

Any guesses would be great.
I don't have the money to send it back to Dell and, of course, the warranty has expired.

I had the same problem with a Sony Vaio. It seems one of the updates put entries in my registry to start a Vaio Lan Manager with Windows.


Check these keys to see if any kind of a 3rd party Lan Manager is running. If so, delete the entries and reboot.

Sorry about the lateness of my answer, but I just had the problem.

Good luck.

Thank you, edjer 184

can you explain this in a way I can understand, I dont get what I have to do, can someone explain in steps
Could someone explain the whole keys thing to me as well please because I don't know how to do all of this. Also I do not have the icon with the two arrows either. I could really do with help please and thank you!
where can I find the hkey_localmachine???
Look for Regedit, run it. Then look through the HKEY_LOCAL_MACHINE folder for the other folders and follow it etc.

I wouldn't recommend playing around with your registry if you're not familiar with what you're doing tbh.

For the Sony Vaio problems connecting to the wireless network look for the Sony utility "Vaio Smart Network" If you can get that to run and provide you with a little control panel with three icons for wirless, wired, and phone - you tick the checkbox on the wireless and your little LED for the wireless card will light up and you are back in business.
Thanks dude..
This solved it. Thanks
worked! thanks!
Thank you
hey guys...

I have a Vaio FJ58GP, and having the same issues with the wireless! I've been reading everyone's comments but still trying to figure out a solution. any help will be much appreciated.

the issue is my laptop isn't picking up any networks. the h'ware switch in front of the machine is switched on, tried everything from uninstall to reinstall software/drivers, still no go. when I connect my router/modem with an Ethernet cable, I am able to connect to the network.

so the question is, is there anything I can do before buying a new wireless card? I looked in the BIOS but couldn't find any wireless on/off switch, unless I am looking in the wrong place.

Thanks in advance.

I have a Dell Latitude Laptop and I have the same problem. I took it to the store where I bought it for a new battery and since then, the wireless networks stopped appearing and so I don't have wireless internet connection. In the Wireless Network connection window there are "no wireless networks in range" and it says "make sure the wireless connection is on" but I don't know where that is....many of the comments that I've read don't help me at all...there is an "i" button in the top center of the laptop...is that it?
try the dell control point manager and check if airplane mode is turned on. took me the best part of a day updating drivers and reinstalling programs to find it.
Hi I am Noemi. I reformat my toshiba laptop from Japanese to English however the wireless LAN enable diable tool is missing and is looking for version. Also, it says that the support device is missing. Please help me about this. Please email me at retrogirl143@gmail.com
Thank you
I have found that most laptops have both a hardware switch and a software switch for wireless. On a Vaio I was asked to troubleshoot, the software switch was off. The control is usually accessed by keystroke or in my case, an icon in the System Tray on the Taskbar (lower right hand corner of your screen). The control for the Sony is not very noticable. Took a few minutes to uncover. I'm thinking the previous suggestions about deleted registry keys would also work because they delete the Sony software in favor of Windows management software.
Thank you
There are many reasons a wireless radio will stop functioning. First and foremost check to ensure your wireless radio switch is turned "on"

If this is the case then ensure you have wireless network drivers installed. (right click my computer, properties, hardware, hardware manager, network adapters)

If it appears to be installed correctly, Try this, Start > Run > type in "services.msc" (without quotes) scroll down the list for "Wireless Zero Configuration" right click, check properties, in the startup ensure it says "automatic" then simply click on "start" Once it's started, right click on your wireless connection icon, select "view available wireless connections" (should still be blank) click on "change advanced settings" then "wireless network" tab and ensure the check box that says "Use windows to configure my wireless settings" is checked...
Apply and OK all and then refresh your wireless network list.

Hope this helps.

Hey, I had this problem on my acer aspire 3680. I think the radio got disabled when my roommate unplugged my ac adapter and the battery drained while the laptop was still on. The only thing that worked for me was to update/reflash my BIOS. It fixed the problem right away, so it may work for others as well.

Hey aj,
I got a acer 3680 also and my wireless switch is not working. Can u help me and tell me step by step on how u got yours to work. Thanks..
Thank you

if wifi switch is not working, just disable wifi control/wifi switch on bios to turn on always the wifi.

Thank you
looks like you unplugged something or broke something or dropped solder on the motherboard.
Thank you

I have a latitude z. The solutioon was -but simple- yet it took a long time to figure out.

There is a small switch that controls the wireless on the left hand side of the computer close to the screen. Battery life is improved if the wireless is turned off, but then the wireless doesn't work. Duh.
Thank you
I had the same problem with my new Sony Vaio - was working online with my laptop in my lap, got up to get a drink, and found myself logged off. Could not find the wireless switch. The trouble shooting guide does NOT tell you where Sony engineers decided to hide your switch. It is located two inches to the left of the audio jack in the front, under the keyboard. It has the word "wireless" next to the indicator light in the front but it doesn't tell you where the switch is located. A simple arrow pointing below would be a brilliant idea that Sony engineers could not produce in their brains. You have to look underneath the laptop, lift it up and then you'll see the switch. When you hold the laptop against your body, it's actually very easy to turn the switch off without knowing what happened and then you scratch your head because you lost the wireless connection. Another sloppy Sony design, that makes the customer feel stupid for not finding the switch.
omg u just saved my night. I know NOTHING about computers therefore didnt know what the hell they meant by using the hardware switch. I thought it was something in the computer I had to find. I was ready to pull out my hair not being able to find it in the computer somewhere. thank you thank you thank you!!! xoxoxoxo
Thank you
I have the same problem too and my computer is a Sony Vaio VGN-NR160E. I have found a file in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
named NSUFloatingUI "C:\Program Files\Sony\Network Utility\LANUtil.exe"

Do I delete this?
Thank you
I have a Vaio 38E, after last windows update I had a problem with WIFI as follows:-

Switch was on, Light was off!!
Diagnosis = no problems yet still no internet...

Initial fix was to go into the sony vaio smart network and turn off the wifi then turn on again...
(either use wifi switch off then on, or double click the two arrows on bottom right of screen, then go into wifi/wireless LAN, then settings turn off apply, then on then apply).
this works but gets annoying as you have to do it everytime you shut laptop or turn off.....

Looked for hours searched all over the place, was getting really p**ed off... then I found it..... after looking at it at least 100 times previously....

There is a check box to start the Sony Vaio Smart Network on startup...
(in the same place I was using to turn off and on the wifi !!!! see above)

deselect this option... and hey presto it works..
If you need it it can still be found in the programme menu....

Much easier than deleting registry files.... and reinstalling wifi....

Hope this helps, :)
