WiFi Is Not Working At All After Upgrade

Sep 3, 2015

I upgraded from W8 to W10. I have Acer V17. For few weeks, everything seemed to be ok... And then, one week ago, I restarted my computer, and I think I saw some actualisation being installed (I thought I turned them off, but I probably did not...). Since that moment I dont have WIFI. And I mean no WIFI at all - my network center says, there are no WIFI networks to connect to.

But that is not true, because on my phone and other devices, there are WIFI networks. I tried to google the answer and tried few things, but nothing works. In Device manager, my WIFI adapter (Qualcom Atheros) ha yesllow exclamation mark, but when i try to update the drivers, it says, they are up to date... but the exclamation mark is still there, an I have no connection. I am completely hopeless, because I need WIFI for my job. I really hate the moment I decided to upgrade this system.

Why Won't WiFi Connect After Upgrade

Oct 23, 2015

Since I updated to windows 10 I cannot get my laptop to connect to the wireless network. The network shows up as available but when I hit connect it says "cannot connect to this network". When I run the troubleshooter it give me the error 'problems with wireless adapter or access point - not fixed'. I have restarted the computer and the router and made sure the drivers are up to date.

WiFi Is Not Working

Jul 29, 2015

I knew I should've never installed windows 10, but I decided to since it's free and all. When I successfully installed it and tried to connect to wifi, it didn't work. My wifi has small range (so people don't guess the password and use our wifi), but large enough for our whole house. I got right next to my router and it still didn't show up on the Wifi List.

Networking :: Can't Enable WiFi After Upgrade

Feb 10, 2016

I upgraded my friends HP laptop to Windows 10. The issue now is I can't enable Wifi. The card is recognized correctly in Device manager and no issues is found with it. It looks like it is fine. However in the Network Settings WLAN is set to "Off" and when I try to turn it on it always jumps right back to off. eg. I can't enable it.

HP clearly state any laptop bought prior to specific date in 2013 will not get any driver updates from their side for windows 10. And updating through device manager only tells me it's the newest driver available.

The Wifi card i Broadcom 4313GN card. I searched for win 10 drivers but did not find anything.They only offer linux drivers on their homepage...

So any solution to the issue or link to a win 1' driver for this wifi card?

Networking :: WiFi Not Available On Tablet After Upgrade

Feb 10, 2016

I have a Chuwi Hi8 tablet. Yesterday I upgraded the preinstalled Windows 10 RTM to the latest build 10586.104 and got the well-known Wi-Fi Not Available problem.

When I open the Device Manager, I see no problems with the installed hardware. Windows reports that all drivers are installed and work correctly. The same concerns the Broadcom 802.11n Wireless SDIO Adapter.

The website of the device (URL...) does not work a lot. They do not provide a driver package I can use to reinstall the drivers. I even can't register on their forum to request the driver pack.

Networking :: No WiFi After Upgrade From 7 Home

Aug 6, 2015

I upgraded mu Alienware M14 from 7 to 10 using the Media creation tool, and now have no WiFi. Ethernet and Bluetooth both show fine, and a wired connection works perfectly, however, not being able to use WiFi puts a damper on the portability of said laptop.

I've tried the reg delete method, which informs me the key is not found, there was no VPN software installed. I do show a network adaptor under unknown devices, but no matter which driver I choose, it is unable to start. Short of a clean installation, and the loss of personal files and/or hours restoring them or reinstalling.

Ever since that happened, the phone has been restarting (Nokia logo) and then the cogs are displayed for abt 15 seconds and the phone switches off. It repeats this if the USB cable is plugged in. I cannot use my phone.

Networking :: Wireless WiFi Not Working?

Aug 20, 2015

When I first installed Win 10 it was working great got my wifi connection working and everything now it seems I cannot get connected. I have tried several times, putting it mildly. I put in the Modem/router address and password and then I go to the site that shows you the wifi connections and mine is not there. But there are about 10 or 12 that are there. I have tried this several times like I said. And I have rebooted to see if that did anything and it made no diff.

It seems from some of the reading I have done this might be a problem caused by an update. It worked great for several days. And while I am thinking of it can you delete all those other wi fi addresses some how.

Drivers Not Working For New WiFi Adapter

Oct 3, 2015

I got my new Wi-Fi adapter today (TL-WDN4200) and in order to access its 5Ghz connecting capabilities, you have to download the updated drivers off the TP-Link website. I did just that. However when I go to device manager, right click my WiFi adapter and update the drivers. This error message appears when I click on the driver file: [URL] ...

I have windows 10 64 bit. Will that be the problem? since TP-Link has not released any official drivers for Windows 10 yet? Will I need to revert back to Windows 8.1 to access the 5Ghz connection?

Dell WiFi Switch Not Working

Aug 1, 2015

I got a new Dell this year, which came with Windows 7 (Dell Precision M4800), and it was working perfectly until the Wi-Fi stopped working. After hours of research and troubleshooting and updating, I figured out that the one and only reason my WiFi wasn't working was because my hardware WiFi switch was not working. In other words, even when I switch it into the on position, it still stays off.

With Windows 7, there was a convenient fix: go into my Bios, go into the wireless category, and tell the Bios to ignore the WiFi switch. This fix worked, and I forgot all about the problem until I upgraded to Windows 10. The WiFi stopped working again. So I went through all that hullabaloo of updating things, and nothing worked. So I isolated the problem to the WiFi switch.

I went back into my Bios, and found a disclaimer: For Windows 8 systems, the Bios does not affect wireless capability because they use their own OS drivers. In other words, for Windows 8 and up, I can't use the Bios to ignore my broken hardware switch. Here is my question: aside from replacing my WiFi switch, is there a way to turn wireless capability on in Windows 10? Is there a way to make Windows ignore the hardware switch?

I went through hours of customer support as well, and 40 minutes after I told them my switch was broken, they told me, " It appears to be a hardware issue." I do like a laugh, but I actually need my WiFi, I am temporarily downgrading back to Windows 7 until I can resolve the issue. But I really do like Windows 10, so I'd like to go back to it asap.

Networking :: WiFi Intermittent On Lenovo T420 After Upgrade

Oct 24, 2015

After the upgrade I performed a "Reset this PC" with "Keep my files". Periodically the WiFi will die. No networks will appear in the list in the pane which appears when one clicks the icon at the bottom right.The fastest way to fix it is to click the left-most button twice, which seems to disable/re-enable and automatically reconnect to the network. I have checked the router. The problem is not manifesting on another Lenovo laptop upgraded the same way. I am using the latest available network driver.So far I haven't performed a clean install due to the time it will take.

Start Menu Not Working And Can't Connect To WiFi

Feb 16, 2016

Recently I ran to several problems on my windows 10 laptop. My laptop is 4K version of Lenovo Y50. It may have to do something with recent updates, but I am not sure when it occured. So, first problem is, that my start menu is not working. When I press the start button either on my keyboard or in the corner of my screen nothing happens and the same with search bar on my taskbar.

Also, some of the icons on right side of taskbar aren't working and one of them is wifi. I just can't find a way to connect to wifi. When I tried it on locked screen it said "connecting to the network is taking longer than usual" and did nothing. I also can't open the windows 8/10 special settings, it does nothing wherever I try to open it. I am also not home right now and can't connect with ethernet cable which seems to work.

Drivers/Hardware :: LAN And WiFI Not Working Correctly After Update?

Jan 24, 2016

My problem is, that one beautiful day my Lenovo notebook with latest Insider Windows 10 (11102) stop working LAN (yellow triangle) and Wifi (after few minutes of connection gives triangle too). In case of Wifi, I can simply turn it off and on again and it works for few next minutes, but LAN stopped working completely. It says, that in this computer isnt any internet protocol, but in setting both (IPv4&6) are ticked. Lenovo sent me to heaven, because drivers are already included in Win 10, so I cant reinstall it. Uninstall of drivers for LAN and Wifi and automatic new install doesn't work for me.

EDIT: I already tried this, but there isnt any word about driver updates of my LAN and WIFI.
