Hello Friend

Thanks for your help, I have the same problem and tried all the steps you mentioned even upgrading bios to A06 with no results.

Unfortunately i have purchased 10 inspiron 3420 and my problem is bigger

This is the first time i feel disspaointed od Dell.

Do you have another way to help us?

Hi, 

For me it was the Wi-Fi device problem, I also expecting same for you.

You can do one thing, call DELL customer care and ask them to replace.

thank you

That's the other issue, I have already asked them and the response was to run the PC diagnostic from web page and the result is that all is ok. Everything was working.

I have cloned this pc to the other 9 and after the generalization with sysprep, the wifi stop working.  Any idea or suggestion?

I have tried one more time instaling (not cloning) all the windows but the wifi is still not working.

Hi ensozh/Santosh Sahu,

Please install the drivers in the order mentioned in the below link.

Kindly attach the snapshot of the device manager if issue persists.

Try the following:

- Safe Mode with networking: If that works, the problem is with a start-up programs or a start up services (solve by process of elimination).

- If the wireless profile is corrupt, try deleting and readding it

- try reinstalling the device driver from the "manufacturer" (Intel, Broadcom, or RealTek)

When it drops, is it no internet, or not connected (huge difference).  If no internet access -- most likely software.  If it is losing connection to the Wireless Access point, it could be the wireless card -OR- wireless antenna (typcially in back LCD cover).

what happens with a wired connection -- if it drops, you are a router or internet connection problem.

I have a same problem.this laptop is very bad.i have a dell inspiron 3420, 14 laptops, access point cisco 4410.all laptops are wireless problem.working properly and some time connection drop.this problem coming 6 to 8 times per day.after this problem we need to connect manually.

Hi Newuser,

I would suggest you to check for the ‘Network Controller’ listed under ‘Other Devices’ in ‘Device Manager’. Please share the ‘Hardware ID’ of the ‘Network Controller’ if it is listed. You may follow the steps below:

• In ‘Device Manager’, right click ‘Network Controller’.
• Click ‘Properties’.
• Click ‘Details’.
• Search for ‘Hardware ID’.
• Provide the numbers after VEN and DEV.

Keep me posted with the information. I will be glad to assist you.
