My DELL Inspiron 15 (3521, Late 2012) was working fine when using WIN 8/8.1 but after upgrading to Windows 10, I am not able to connect to WiFi.

Network icon on task manager is showing red X on it. Tried downloading the all latest driver from DELL website but still it's not working.

Anyone please help. Thank you.

Note: I can't use internet on above laptop. I need to download/access internet from other computer and then bring it to laptop if there are any drivers available.

Just downgrade and wait for a later version of Win10, you have a year to upgrade.

Pretty Sure there is an option to Downgrade to an older OS.

I've seen this quite a bit on all manufacturers. I've also seen it with other hardware devices. Seems not everyone was ready with compatible drivers and maybe Win 10 just wasn't quite ready to begin with. I had a HP recently that was a pain to get the wifi working. The latest drivers from Intel and HP broke the adapter so it couldn't even be enabled. Had to roll the system back a month and try 2 - 3 different drivers until I found one that worked.

If you decide to reinstall windows 10 and run into this issue again. I would suggest either doing a clean install of windows 10 or if that is not an option for you... Uninstall the drivers, and any related dell software.

Sometimes there is a vendor/3rd party application used to turn wireless on and off as well as connect to networks.

This might not function correctly with Windows 10, so you need to get it all out of there.

Once drivers and software are removed, download the latest Windows 10 compatible drivers and install them. If there is an option when installing the drivers... try to do the driver only installation so windows will manage your wireless.

Also from what I have found most windows 8 drivers work with windows 10.

Therebis a way to turn off WiFi radio in Win10, see if it was turned off by any random chance.

Could be a dumb suggestion, but try opening Command Prompt (as an administrator) and typing the following, without the quotations: "ipconfig /renew".

Not a dumb suggestion! It is a common troubleshooting step!

However, in this case with a Red X, this means he is not even able to associate and/or authenticate to his wireless network. Association and authentication must occur before an IP address is issued, unless using layer 3 authentication, which if you don't know what that is, you're not using it.

A yellow triangle with an exclamation mark can indicate a problem getting an IP address, in which case issuing a renew command will force the device to send another dhcp request to attempt to get an IP address.
