Sony Vaio wireless switch problem

Solved/Closed

Hello,
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.

Thanks,
Kimberly

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 wireless, 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.

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.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

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.

Hi there,

I have exactly the same problem with my Sony Vaio and I have no idea to fix it. Sorry but what do you mean by entering the keys HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion­\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\­Run

Can you please, please send me the details on how to do this?

thanks a lot.

Hey! I had the same problem for a while, but then magically I had an epiphany after searching for 40000 hours on how to fix the LAN switch. On the bottom right hand side of the screen there is a green and purple arrow facing opposite directions, double click it. (It's hard to remember everything) I think it will bring up a picture with a bunch of boxes on the left side, click the wireless network one. TA-DAAAAAA!!! If you can figure out how to connect my Vaio (with Windows Vista) to a nonbroadcasting wireless network with WEP security (i have all the codes) I WILL LOVE YOU FOREVER

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
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.

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

I have a latitude z. The solution 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.

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, :)

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.

For those that have a problem with the switch turned on and NOT having the LED light on, as well, I found a solution from another forum. This site happens to be the first site when "GOOGLED" and I thought I'd put this here.

Just remember to reboot your Sony Vaio.

I have an HP. click start, then programs, then network and internet.

Make sure your hardware switch is turned on. If that doesn't help, then here's something u can try.

Go to Device Manager and disable the wireless card and enable it again. That worked for me. :)

Anyone having issues with the wireless switch / button etc not enabling their wireless, first check that the device is not disabled in BIOS. To check this, press F10 (or whatever it says on the first boot up screen when you power on your laptop) to enter System (or Computer) Set Up. Navigating around there you'll find a section called devices or something like that. Make sure the wireless card is not set to disabled.

If the card is disabled in BIOS then no amount of jiggery-pokery in the registry etc will work!

My HP laptop wireless switch wasn't working, and eventually I got it working again by the following:

write down or back up all your BIOS settings
remove external power and battery
(most important!) remove BIOS backup battery (a small watch-type cell, mine is next to the hard drive)

after 30 seconds or so, replace all batteries and power up

BIOS will give you a error of some kind (Check-sum for example) when you boot,
go into BIOS setup and reenter your date and time and any other data. Mine only needs date and time
but in case yours is different, be sure to write down your settings beforehand.

That fixed my wireless switch problem.

On a Dell Vostro Laptop there is a physical switch on the left hand side that can disable the wireless - make sure it is pushed forward.

Thank you so much (not that any of you should be looking at this thread anymore) for over a month I thought I had a broken wireless switch, and have been using a wireless USB and unloading and reloading drivers, etc, etc. , but Kimberly here reminded me to try the FN - F2 key - duh.

My husband manages to disable his wireless by pressing shift and F2 at the same time. The solution for him is to use the Windows key +F2. Hope this helps.
