Windows 10 - WiFi does not work

This seems to be a problem affecting a lot of people based on my last 11+ hours of trying to fix it and seeing so many posts on the Microsoft support site, some here on Dell, and elsewhere on the interwebs.

Ever since I updated to Windows 10 (I have the 'Pro' version, although I doubt that makes a difference), I have not been able to connect to the Internet via WiFi. I am using my iPhone to connect at the moment. I am hoping you all might be able to help. 

I have a Dell desktop, although this problem seems to affect laptops too. Here's my system:

Dell XPS 8700
Processor: Intel Core i7-4790 CPU @ 3.60 GHz
Installed memory (RAM): 8.00GB
System type: 64-bit Operating System, x64-based processor

Windows Internet Connection Troubleshooter

I have run the trouble shooter (Right-click on WiFi icon in system tray) at least 20 times, but no luck. 

RedmondPie.com

A post on RedmondPie.com seems to have the most knowledgeable suggestions, although unfortunately none have worked for me, but they might for others. I am also mentioning it so that you know I tried the main suggestion in the post, which is also on the Microsoft website (deleting a VPN something-or-other from the Registry), and many of the suggestions in the comments:

Revert to Previous Network Adapter Driver

One of the suggestions, which seemed to help a lot of people, is to revert back to the previous network adapter driver. I tried it, but it did not work. Here is my installed driver, and the previous one, which I installed using the "Roll Back" function (Device Manager > Network adapters > Dell Wireless 1704 802.11b/g/n > Properties > Driver > Roll Back Driver):

INSTALLED DRIVER:
Dell Wireless 1704 802.11b/g/n (2.4 GHz)
Driver Provider: Broadcom
Driver Date: 7/30/2015
Driver Version: 7.35.295.0
Digital Signer: Microsoft Windows Hardware Compatibility Publisher

ROLLED BACK DRIVER:
Driver Provider: Broadcom
Driver Date: 6/2/2013
Driver Version: 6.30.223.256
Digital Signer: Microsoft Windows

I went back to the current driver (Version: 7.35.295.0) and tried Update Driver, but that did not work.

Dell SupportAssist

I used Dell SupportAssist - checked my system, and it did find the problem - no wireless connection. Interestingly, it said the signal strength from my router is "very strong", but it was not able to fix the underlying problem. This result made sense because I am able to connect to my wireless via my iPhone 6 and my Chromebook.

Windows 10 Updates

I have run all Windows 10 Updates. 

Dell Technical Updates

I subscribed to Dell Technical Updates, and installed two Recommended updates related to the network adapter:

BCM_Wireless_WT4_D3P4M_A01_Setup_ZPE

Release date:7/29/2015 3:10:01 AM

I had great hopes that these installations would fix the problem, but alas, my hopes were dashed. 

Reboots

I rebooted after each fix attempt.

Internet Service Provider

I called my ISP (Charter). I reached someone right away, and she was very polite and professional. She confirmed that my router was working fine. She said a good number of customers have had this problem after installing Windows 10, but that unfortunately it was not something they could solve since it is a Microsoft problem. Although she recommended contacting Dell (after ascertaining that I had a Dell PC), and even had the Dell support number for me. (It was after hours, so I'll have to wait until business hours to call Dell, but I'll wait to see if I receive any replies here first.)

Microsoft Support

I called the Microsoft support line, after spending 2-3 hours on their support forum, waited on hold for 52 minutes, and then was disconnected. I called back and received a recording saying they were not open. 

System Restore & Reset

I tried a system restore, but that (predictably) did not work, since the problem is with Windows 10. 

I tried a system reset--losing all the programs, er, I mean 'apps', I had installed over the past month since I but the XPS 8700--but it did not help.

Any Suggestions?

Please let me know if you have any suggestions to fix this vexing problem.

Thank you very much,

Mark

RE: Windows 10 - WiFi does not work

I can hardly believe it, but I solved it. 

The clue was in that long printout from the Windows troubleshooter:

Windows cannot connect to "[my WiFi name]"
The wireless network security key is not correct.

I spent a lot of time trying to figure out how to correct the network security key. Somewhere along the line, I figured I would uninstall the network adapter. I had reverted to the previous version, and when that didn't work, updated it, but I realized I had never uninstalled it. 

It took me a while to figure out how to reinstall it. Eventually, I used the Dell process of detecting my computer and then telling me which drivers were recommended for my system.

I installed two of the top 3 - one of them, an Intel driver, would not install. I am pretty sure this is the one that fixed the problem:

BCM_Wireless_WT4_D3P4M_A01_Setup_ZPE (1).exe

I did have to reboot, and then I right-clicked on the WiFi icon in the system tray, selected my WiFi, clicked "Connect", and then it asked me for my network security key. Fortunately, my ISP, which provided the router, makes it easy to find the security key (sticker on the router). I typed it in, and lo and behold, I had WiFi again. 

I sure hope Microsoft fixes this problem so that more people do not have to spend nearly 14 hours searching for a solution!

RE: Windows 10 - WiFi does not work

I think that was a second copy of the driver, so it will probably be listed as:

BCM_Wireless_WT4_D3P4M_A01_Setup_ZPE.exe

RE: Windows 10 - WiFi does not work

Update:

After reviewing my notes, it might have been the following two driver updates that helped. These driver updates are specific to XPS 8700, but I imagine there similar updates for other Dell desktops, laptops, etc. Dell made it much easier with the System Detect tool.

I also highly recommend subscribing (via email or RSS) to Dell Technical Updates. They are almost a secret (not on purpose) as it is hard to find the "how to subscribe" info by searching the Dell website. That link will take you to the right web page though.

RE: Windows 10 - WiFi does not work

I have Dell Inspiron 14Z. I had windows 8.1 but upgraded to Windows 10. After the upgrade, the wi-fi gets disconnected all the time. I have to restart my computer for the Wi-Fi to work again. Sometimes, the Wi-Fi works by simply using the troubleshoot problems option available after right clicking on the Wi-Fi icon. This is not a good thing. All my other devices - iPhone, iPad, MacBook Air connect to Wi-Fi without any issue.

I uninstalled the Wi-Fi driver and re-installed but the problem persists. Does Dell Support have any suggestions? I could not find any solutions from Microsoft support forums.

Network Adapter for Wi-Fi is Intel(R) Centrino(R) Wireless-N 2230, Driver Version 15.18.0.1

RE: Windows 10 - WiFi does not work

I was having a similar problem.  I updated the drivers, which didn't resolve it. 

What appears to have resolved it was going into the configuration of the WiFi adapter and clearing the checkbox allowing the computer to turn off the device to save power.

RE: Windows 10 - WiFi does not work

Had similar problems on a new Dell 8700 but also on a XPS 13.

The 8700 was finally fixed by following step 6 from Microsoft to purge all the network drivers:

windows.microsoft.com/.../fix-network-connection-issues

There are a number of network drivers installed now that weren't there previously.
