Wireless network not working after windows 7 reinstall

I did a custom reinstall on my dell latitude e5420 laptop using dell windows 7professional 64bit sp1dvd and now my wireless network is not working. I tried turning the switch on and off, restarted my laptop, and I also went to dell suport and downloaded all the recomended drivers and it still doesnt work. I dont know why its like that and I really need help with it.

I went to device manager and noticed that under "other devices" there is a yellow exclamation mark on the network controller.

Re: Wireless network not working after windows 7 reinstall

Hi,

This can be an issue with the missing network drivers on the computer.

Install the wireless drivers on the computer.

Update the wireless network drivers for the computer.

  1. Visit the following website: http://dell.to/T2hKYc
  2. Enter the Service tag of the computer in the box provided and click “Submit”.
  3. In the next page, click drop down arrow to select the Operating System which is installed in the computer.
  4. Under category Network, select the drivers accordingly and click “Download File” and save the file on desktop.
  5. Follow the on-screen instructions to update the Wireless drivers.

If the issue persists, check the wireless connection in Safe mode with networking (restart the computer and tapping F8 on dell logo. Select Safemode with networking).

Also, try updating the update the wireless router's firmware to the latest available.

For more information, I have provided a link below which can fix the issue:

RE: Wireless network not working after windows 7 reinstall

I purchased a used Dell Latitude E6320 with no OS installed, which was fine because I would in any case have erased the disk before using it. 

I first loaded Ubuntu LTS 12.04 using a live disk and it ran fine. Specifically, the wireless indicator light turned on and I was able immediately to log on to my network and access the internet.

I then downloaded Windows 7 professional 64-bit from digital river content (X17-59186.iso) using another computer (iMac) and burnt the image to a disk. I used that disk to install a fresh OS in my laptop. At the point where it asked for the MS product key, I provided the key which was in the laptop's battery compartment. 

The Windows 7 installation proceeded normally, but when it was finished the wireless indicator light was not illuminated. There was no network connection. I went to network connections, but the control panel said "no connections are available." Troubleshooting couldn't identify the problem. When I tried to set up a networking connection I got the message, "Windows did not detect any networking hardware."

I shut down Windows and again loaded Ubuntu from a live disk. In the process of booting, with wireless indicator light came on and I was immediately able to log on to my network and access the internet.

I concluded that the Windows OS build I loaded did not contain all the necessary network drivers for my laptop. When I tried to download wireless drivers from the Dell site to a USB drive using my iMac (as I have no internet access running Windows on the laptop), the site wanted first to download and install the Dell System Detect application. This of course would not install, since I was trying to download it to a USB drive, so I was not able to download the drivers.

It seems I am stuck in a loop where my laptop lacks the drivers to access the internet, but the only way I can download the necessary drivers is via the internet. 

Can you suggest an alternate build of Windows 7 which would have the drivers which I require, or, alternatively, some way to load the necessary drivers into my computer without use of a direct connection to the internet.

Many thanks.

Hi DELL-RAJESH R,

I have the exact same problem with what have been mentioned above and follow the same solutions that you've proposed, unfortunately it doesn't work as well.

I've tried clean re-install Win7 again this time following the advice using Latitude E5420: Windows 7 Driver Install Order as link below,

www.dell.com/.../EN

but it still doesn't resolve the issue.

I have other laptops (E5400, Lenovo and Asus) that works perfectly using the same home WIFI and my iPad + Android also have no problem connecting to the same WIFI. So confirm it is this E5420.

Appreciate your further advice on this.

Same problem here.  What a dumb situation!  And the first report was about 5 years ago, so there is no hope that Dell will ever address this.

I just turned my son-in-law's laptop into an internet-less doorstop.

Thanks Dell!

If you are incapable of understanding that after a Windows 7 OS install that you need to install the drivers in proper order, then your case is hopeless.

Don't blame it on Dell!

Windows 7 Installation Media is from 2011... and it lacks drivers for most newer hardware such as wireless cards. If you expect basic driver support natively then you'll need to use a newer Operating System such as Windows 10 Version 1709 (September 2017) which has a much wider set of native drivers.

Otherwise you'll need to manually download the drivers on another computer and copy them over using a USB flash drive and install them.

Yeah, and possibly create more problems for him than not having wireless.

Buyer beware!
