Thank you for your reply. I tried all the above steps, but still the problem persists.

My System model is

Processor: Intel(R) Core(TM) i5-2450M CPU @2.50GHz

Installed memory: 8.00 GB

System Type: 64-bit operating system

2. Click on ‘Device Manager’.
3. Click the + sign to expand the ‘Network Adapters’ entry.
4. Right click the wireless adapter and click 'uninstall'.
5. Once done, click on 'Start' and click on 'Control Panel'.
6. Click on 'Programs and features'.

9. Enter your system's Service tag and select the operating system.
10. Go to 'Network' and click on the appropriate wireless driver for your system.
11. Click on 'Download File' and select 'Single-file download'.

In case the issue still persists, BIOS update might fix this issue:

Note: Please save any unsaved data as your system will restart automatically after updating the BIOS. Disconnect all the external peripherals like printer, camera, scanner, external hard drive, flash drive etc. Also, the battery should be charged 10% or above.

1. Click on the link to update the BIOS: http://dell.to/UmY8yD

3. Click ‘Run’ to update the BIOS.

Keep me updated. Please reply for any further questions.

Dear vikram M

Thanks you for your reply.

I have tried to uninstall the wireless driver but I am bit confused to do it.

I opened device manager and clicked + sign to expand "Network Adapters" entry 
and following entries were displayed,
>Bluetooth Device (Personal Area Network)
>Bluetooth Device (RFCOMM Protocol TDI)
>Intel(R) Centrino(R) Wireless-N 1030
>Microsoft Virtual Wifi Miniport Adapter
>Microsoft Virtual Wifi Miniport Adapter #2
>Realtek PCIe FE family Controller

Please Note, in above ">Microsoft Virtual Wifi Miniport Adapter and 
>Microsoft Virtual Wifi Miniport Adapter #2" has not working symbol. 

I right clicked on ">Microsoft Virtual Wifi Miniport Adapter 
and checked the properties and it shows the device 
status "This device cannot start. (Code 10)"

and similarly on ">Microsoft Virtual Wifi Miniport Adapter #2" and 
it shows "Windows has stopped this device because it has reported problems. (Code 43)"

I am not sure which one is the appropriate wireless adapter to uninstall and reinstall 
it again to rectify my problem. So I kindly request you to mention the wireless 
adapter to uninstall.

Awaiting for you response.

Thank you!

iamdhinesh,

Please continue with DELL-Vikram M

I would like to add this information.

Did you try this tweak?

Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.

If yes, you cannot uncheck the power management box for the Microsoft Virtual Wifi Miniport Adapter(s) or they go missing.

Rick,

Thanks for your reply.

I think I did one mistake. I have not only unchecked the box "allow computer to turn off this device to save power" of wireless adapters, but I did the same thing for "Microsoft Virtual Wifi Miniport Adapter and

Microsoft Virtual Wifi Miniport Adapter #2" , power management.

After that incident only I noticed the error. So I kindly request you to suggest me an appropriate solution.

Thank you!

iamdhinesh,

For the Microsoft Virtual Wifi Miniport Adapter and Microsoft Virtual Wifi Miniport Adapter #2 make sure to go back and check the box, allow the computer to turn off this device to save power. The adapters should not go missing with the box checked.

If the still go missing, then reply back and maybe DELL-Vikram M has another solution.

Rick

Rick,

I did it. Just check the attached picture.

iamdhinesh,

Use the system for a day and see if the Microsoft Virtual Wifi Miniport Adapter and Microsoft Virtual Wifi Miniport Adapter #2 goes missing or gets the yellow exclaimination marks.

Post back and let us know.

Rick

Hello

I am having the same thing happen to my laptop. I have done everything you have said to do and it still does it. My laptop is an M5040 not really sure where to go now. Help please

I am having the same issue with the DEL E7440 running W7 using the Intel Wireless AC 7260.  This is an issue as I have meeting all day and I don't want to disconnect form the network when I pop the docking station or when I close my lid.

I found a workaround!  I normally do not install the “Intel WiFi Software” to control since windows does a decent job at it.  Well as a hail marry pass I installed the software and now when I close the lid wireless stays on.  Also I found out that if you have a docking station and you have Ethernet connected to the docking station, wireless radio will shut off.  So if you want wireless to never shutoff, install the Intel software (different then the driver) and unplug any Ethernet from your docking station.

Hey SSN-PAUL, 

I'm sorry that you too have the same problem. Now I have a different problem, When I close the LID (ON Main Power) internet disconnects automatically. But When I close the LID(on Battery) internet does not disconnects. This is really bugging me. No technical guys can solve this issue. Very disappointed. 

Hi Dhinesh,

I have a Dell Inspiron 15z and just spent the last 2 hours trying to fix it. What just did it in the end was a simple BIOS update. I had exactly the same problem as you:

Lid open, on charger: OK

Lid open, on battery: OK

Lid closed, on battery: OK

Lid closed, on charger: NO WIFI

Try the BIOS update again, maybe this will help.

All the best mate!

Same problem with Vostro 3550. I will try using IntelPRO tools later to see if it will change something.
