I had the same issue on an Inspiron 13 I just received from the Microsoft Store. Very frustrating. The wireless card kept shutting down and I would have to disable/enable it through the device manager.
I tried the above and it did not work.
I went to the Dell Support site, used my service tag and found an new driver for the network wireless card.
The driver is dated 15 Dec 2015. Once updated this fixed the problem.
Hope this helps.
Thank you for the suggestion, I tried installing the updated Network_Drivers and it resolved the issue. I do not have the wireless connection drops any more.... !
This doesn't work. I've got my wife's brand new computer and it can't even locate the wifi driver. It appeared for a short time under the drivers but now it's gone again. This combined with a black screen upon booting. It's going back so long dell...
This is the exact fix I needed. Download and shuffle it over on a thumb drive and everything works great. Thanks!
This helped solve the problem.
The problem occurred when i used a pen drive this morning. Since then I faced similar problems and had to restart my laptop multiple times. It was very frustrating as I was in the process of completing some urgent task and had to move to another machine.
My problems started after I received an update notice three days ago from Microsoft about a Windows 10 update. As usual, I followed the directions and after one unsuccessful attempt, I finally got the Windows 10 update installed. Ever since that update, my wireless network adapter has been ridiculous. Connects to the net, then loses the connection or should I say it "says" it's connected but when I try to open Internet Explorer, it just can't connect to the Internet. I've tried EVERYTHING and nothing happens. There is a test on Dell Suppirt Assist that has the little FIXIT button. I've used that, restarted my desktop as requested, and it'll actually pull up a webpage for a few seconds...then it loses the connection and is out again. In two days of trying my best to fix this issue, I've only seen maybe thirty seconds of a webpage showing on my screen before its out again. All because of a Windows 10 update. I'm getting to the point where a Mac is starting to sound better and better! Please help...I'm frustrated!
This was so helpful! However, now my Network Adaptor has disappeared from Device Manager. Will I need to download it from another computer and reinstall that way? I got to the part in your instructions where you Update the driver and then it kept telling me that the driver was already installed. Then it just disappeared. I'd really appreciate any insight you might have!
Okay, so my Network Adaptor was just hidden in the list. I clicked Show Hidden devices and it popped right up. Phew. But what do I do if it keeps telling me "Windows has determined the driver software on your computer is up-to-date."? Thanks!
If your driver is up-to-date, there's not a lot more you can do. Are you still having problems maintaining a wireless connection to a network?
I would suggest trying the Dell Support page and seeing if it identifies any needed updates for your wireless hardware. Hopefully you can stay on line at least long enough to identify any possible updates (and then you can use another computer to get those installers). For what it's worth, the Device Manager says that the wireless card I have in my machine is an Intel dual-band Wireless-AC 3165. For that device, the driver update that I suggested worked like a charm.
If you're adventurous, you could try using the Device Manager to uninstall the existing driver for your wireless card and then re-installing the update. That is a very risky procedure; please don't do it unless you have a complete backup and know what you're doing.
