@davoimail94 thanks for getting in touch. After updating the BIOS, can you advise the following -

a) If you press the Fn and PrtScr button is the wifi now enabled?
b) Is the wireless card detected in the BIOS? (To access the BIOS power on the system and keep tapping the F2 key. It should be listed under System Information then Device Information under WiFi device)
c) Do you have the wireless and bluetooth enabled in the BIOS?(Access the BIOS as above and then select Wireless. Ensure both are set to "All Enabled"

@davoimail94 Hi David, 

Thats good to hear the WiFi card is at least detected. it sounds like now have either a configuration error or a connection error.

First off, I would reinstall the wireless driver again. Here's the link - https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=WMN95&osCode=WT64A&productCode=latitude-e7450-ultrabook

Once that's installed you need to check and see if the system can see network connections. At this point I would work through the following troubleshooting wireless networks guide - https://www.dell.com/support/article/us/en/19/sln297740/windows-10-wireless-networking-usage-and-troubleshooting-guide-for-the-home?lang=en

Once that's done, install the bluetooth driver for the system - https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=565N6&osCode=WT64A&productCode=latitude-e7450-ultrabook

Then follow this bluetooth troubleshooting guide to pairing devices - https://www.dell.com/support/article/us/en/19/sln297856/how-to-pair-dell-bluetooth-devices-in-windows-10?lang=en

Hi Alan,

I'm experiencing the same issue, my E7450  is not detecting wifi networks.

I tried to re-install your recommended wifi driver, but my laptop showed "operation is unsuccessful".

What is your recommendation?

Thanks,

@Rch204 the error that you received may depend on the correct wireless card being installed in the system. It could also be an issue with the folder that you are extracting the file to.

Before looking at potential software issues, I would look at troubleshooting the hardware first.

a) Is the wireless card seen in the BIOS? (Power on the system and keep tapping the F2 key in rapid succession. The card should be listed as a device under System Information)
b) Is the card set to function with the wireless switch enabled? (From within the BIOS, look for the Wireless Section. The boxes should be ticked for WiFi and for the wireless switch)
c) When you boot the system in Windows, do you have a red X in the system tray over the wireless icon?

I'll drop you a private message for your service tag so I can check what wireless card was purchased with the system.

Hello.

I solve my problem with replacement my home and office Wifi routers, and now it's work great.

 I'm still not understand reason. why some Wifi signal's not detected, or detected and losted.

Hi 

I found same issue for wifi and I was trying to reinstall but it's showing unsuccessful. Then I tried to see in BIOS option that my wifi driver installed or not. I found there " intel wirless" nothing else. How can I reinstall wifi driver for Dell latitude E7450?

Before trying to install the wireless I would recommend ensuring the hardware is detected and enabled correctly. 

a) Is the wireless card seen in the BIOS? (Power on the system and keep tapping the F2 key in rapid succession. The card should be listed as a device under System Information)
b) Is the card set to function with the wireless switch enabled? (From within the BIOS, look for the Wireless Section. The boxes should be ticked for WiFi and for the wireless switch)
c) When you boot the system in Windows, do you have a red X in the system tray over the wireless icon?

Once that information has been checked you need to install the correct wireless card driver as there are various different cards available. As you have mentioned seeing Intel in the BIOS that would suggest it's one of the Intel cards. I would recommend installing this driver - https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=8k8hc&oscode=wt64a&productcode=latitude-e7450-ultrabook

Hi Alan!

Thanks for the speedy response. I have checked the above sections and found the problem in wireless. In wireless section, there is nothing! I clicked in "Wireless" showing empty.Under the page there is another option to import default setting. I don't know what should to do now.

BTW, I have downloaded the driver from the given link and installed that but still it's showing "your connection was interrupted" while browsing the websites. But WiFi showing connected as well. After a certain time, loaded the page and then after couple of mins showing again interrupted. 

Thanks a lot. 

Hey Guys tried all those fixes and it did not work.

i then re-seated the wifi module and it worked first time 

Cheers

2 solutions: 1- Disable and enable WIFI card. 2- open network card properties, choose configuration, then power management tab, uncheck "allow this computer to turn off this device..." Best Regards, Alaa
