    LOL Is the next article “Windows 10 does not work after upgrading to Windows 10”? Just teasing…

    Seriously, these are great articles… please keep posting them. Your site is turning out to be the best source for Windows 10 usability topics; and that is quite impressive.

  2. Ha Ha. But thank you. 😀

    no no problem.

    That happened on one of the computers I upgraded. Tried every trick I could find on the internet until I finally just shut off all my sharing options, deleted my network connection in device manager and then rebooted so Windows would reinstall it. Restarted all the sharing options and after that it worked. Additionally, a few days after the upgrade, one of our laptops wouldn’t connect to our NAS. Never did get that one fixed and pulled an old laptop out of the closet and let it upgrade and it works fine. So it seems like networking is the weak spot in Win10.

    Day before yesterday, I updated my OS from Windows 8.1 to Windows 10. But after the update my WiFi is showing limited connectivity. I disabled and re-enabled my WiFi adapter, tried to Roll Back the WiFi driver, then updated the driver, tried to disable the IPv6. I even tried the following commands in the Command Prompt (admin):
    reg delete HKCRCLSID{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f

    netcfg -v -u dni_dne

    But it says that it is not installed.

    I tried to make my phone a hotspot and connect to the internet. It worked.
    I assumed, maybe its the router that might have some problem, and so I took my laptop to my friends place and tried connecting to his WiFi network. I got the same problem again (The WiFi shows limited connectivity).

    Could you please help me out here?

    I currently have the same problem with a Dell Vostro and looking online there are no known solutions as yet.

    I have been working on this issue on a Dell Vostro 3550 just upgraded to Windows 10 with the yellow exclamation on the network connectivity. My solution to the problem has been to manually override the driver from Dell Wireless 1702 b/g/n to 1703 b/g/n, and then change in advanced settings HT mode from HT Mode 40 to HT Mode 20/40

    While installing another driver beforehand, it blue-screened and would not boot back into windows, I had to go into safe mode and uninstall the wrong network driver and reboot before I could continue testing others, so be prepared that this can happen.

    Hope this helps someone else!

    My laptop was unable to find any wifi connections after Windows 10 upgrade. Tried restarting router and laptop, still nothing. Found this link – but before deleting any settings, looked in Device Manager, found wifi adapter had an exclamation mark next to it, clicked on update driver and this resolved the problem

    Important Note to any Kaspersky user.
    I had this issue on my computer and nothing worked (I tried all sorts)

    But I have just upgraded my Kaspersky (in my case Kaspersky Internet Security) from version 15 to the new version 16.
    After doing this I relies that it was Kaspersky which was blocking my Wi-Fi adaptor (I have no idea how).
    Just thought I would pass this on if it maybe could help anyone.
    Also I uninstalled the old version before installing the new which may of also helped.

    My wifi didn’t work running on battery. Restarted and plugged in, works fine. …..

    Gays later used on a/c wifi just fine. Unplug getting ready to shut down finish last post. ….no connection. It’s either a glitch out a stupid sitting that needs changed

  11. RJB

    Have tried all suggestions & nothing has worked – any other suggestions?

  12. Chris

    I managed to resolve this issue by going to: Control Panel > Device Manager > Network Adapters > right click on the troublesome wireless adapter and select properties.

    Go to the “Advanced” tab and on the “802.11n Bandwidth” option, select “20MHz/40MHz Auto” and on the “Roaming Aggressiveness” option, select “5. Highest”. Good luck!

    Hi, I just followed your instructions regarding deleting the registry entry (it wasn’t there). I previously uninstalled my VPN program, reset Windows 10 (and lost several important programs in the process !), uninstalled AND updated the network adapter BUT none of these have worked !!!

  14. Maya

    Hi Anand,

    Tried both commands but for both it will show “The system cannot find the path specified”.

    What can i do about this

  15. Hindi

    Got the same problem today, i wish i didn’t update. i need the internet for a school essay and time is ticking, so frustrating.

    Hi all,

    I installed Windows 10 some days ago and had the same problem with my laptop. There was no Wi-Fi option visible with my Atheros Wi-Fi Network adapter and so I had a driver issue too. I managed to fix it and so thought I’d join just to help out anyone else with the same issue.

    First thing I did was check if “Flight Mode” was on, which mine was and so it was lucky that I checked!
    (for anyone who doesn’t know, just click on the network logo on the bottom right, right-click on Flight Mode, go to settings and select off on the toggle switch. You can just tap the Flight Mode button to toggle, but mine was on and I couldn’t see the Airplane logo on the taskbar until Wi-Fi was set up).

    I then went into Device Manager and there was the usual small yellow triangle warning on the bottom left of the adapter and so I plugged in an Ethernet cable and right-clicked on the adapter icon/text and selected “Update Driver Software..”. It said my driver was up to date, but the Wi-Fi was still not visible and so I then right-clicked the same adapter and selected “Properties”, then the “Driver” tab and then selected “Uninstall”. and restarted the computer.

    I was expecting to reinstall the driver, however as soon as I completed this the Wi-Fi worked and it asked me to change my Wi-Fi settings.
    Hope this helps anyone with the same issue.

    Thanks Chris, I tried every other trick mentioned online but in the end it turned out to be a simple problem. Just by selecting the “20MHZ/40MHZ Auto” it started working. In the end it meant that it was just about using the right type of frequency.

  18. Ross Chineselivesmatter Welfor

    Running windows 10 and no other programs connect to the internet except MS edge, google Chrome is a no go and the same with Steam

  19. Gadah

    I Got mine resolved by just goint to Device manager, then Network Adapters. On the expanded list of network adapters, find your wfi driver. Right click on it, go to properties, and then advanced. In the advanced tab you will see there a list on the left and on the right the status of the highlighted component. highlight “40 MHz intolerant”. If the status in the right panel is “disabled”. click the dropdown menu and select “Enabled”. click ok and you are fine.

    if you conneted first and at the second time you cannot connect, i pull out the battery and it work,

  21. Anton

    Chris, thank you! This also resolved my frustrating issue of always restarting 2x to activate Wi-Fi when power was unplugged and notebook stored. Auto setting worked on 802.11a bandwith.

  22. Riyaz Ab

    HKEY_CLASSES_ROOTCLSID{988248f3-a1ad-49bf-9170-676cbbc36ba3} Key is not found , but still have problem with my wifi in Windows 10, I tried many ways to fix the problem through command prompt..

  23. Micah Frank

    Thank you

  24. Shruti Manohar

    didnt work for me 🙁

  25. Olivia

    Yesterday I updated to Windows 10 and realized that the internet that I connect with would not accept me to use the wifi. I reset the router and it worked, but now today it has the same problem and I had to reset the router again. Is there any way to not have this happen? I don’t want to have to keep resetting the router, it’s disruptive to my family.

  26. Skye

    Ok, I have Toshiba Envy Touchsmart M6-K025dx. It doesn’t have DNI_DNE or the HKEY reg key either. Still, since I upgraded to Windows 10, my laptop won’t see WiFi. For example, I’m sitting at work and I had to restart my computer twice before it even saw my work’s wifi. It said it was still connected to the wifi hotspot on my phone which had been turned off for several hours. I don’t know how to fix this! Please help!

  27. oko

    how about this: after upgrade to WIN 10 wifi recognizes Huawei wifi router, but cannot see any of 2 TP-link routers which I have? I tried different channels, security setup, firmware upgrade. no help. I can see only Huawei hotspot, but not TP link(its standard 2,4ghz model). PC is coming from Lenovo-M53. before upgrade all was working great…thank you

  28. bryan

    Hi Anand!!!.

    Wi-Fi adapter missing after automatic windows 10 update. Yesterday I had this issue on my computer and nothing worked. I tried all sorts.

    Device Manager shows the driver is working, but network and sharing does not list the Wi-Fi adapter.

    I resolved this issue by going to: Control Panel –> Network and Internet -> Network Connections:
    Rick click-on Ethernet adapter -> Add to Bridge

    Waoooooo My Wi-Fi adapter is now available. After I deleted the bridge.

  36. Thanks for posting this. Hope this helps someone someday. 🙂

    This fix the problem for me on 2 different laptops and a surface pro on windows 10.

    Link to fix the wireless connection issue:


  38. After Windows 10 auto upgraded on my laptop [from 8.1], my wifi stopped working. Strangely I could see other networks but not my own. That is, in the list of visible networks, my own network was missing but there were 10 others. On checking the Wifi Adapter I noticed “Unable to authenticate” on it. After checking Wireless Properties for the adapter I found it was trying to connect to the next strongest visible network. I removed that network and that removed the “unable to authenticate” problem. Then I disabled and enabled the wifi adapter and my network showed up. Entered the password and since then it is working.

    You are a legend !
    This worked for me on a HP Elitebook Revolve 810 G1….. Tried so many other options….

  40. Madhav Desai

    Here is the solution to fix the problem with the Wi-Fi adapter after Windows 10 update:
    Go to Device Manager (type ‘Device Manager’ in the Run window for Windows 7/8 or Cortana window for 8/10);
    Go to Network Adapters;
    Find the wireless adapter and uninstall it by right clicking and selecting ‘uninstall’;
    Click on ‘Action’ from the drop down menu and select ‘Scan for hardware changes’;
    The adapter will be reinstalled and will start working as good as earlier.
    The re-installation can also be accomplished by shutting down and re-starting the computer.
    One downside of this process is that all the wireless networks saved on the computer are lost and will have to be re-established.

    I have a similar w-fi problem w/Windows 10. I can connect via my guest network but not with my main network. Performed the driver update (Realtek RTL8188EE 802.11B/G/N), restarted, still could only connect via guest network. My router is a Western Digital N750, it worked perfectly with my old Window7 laptop.

    My 2nd problem is that Windows 10 cannot connect with my router at, not in Firefox or IE so it’s some bizarre Windows10 failure.

    Can someone here help me with these problems?


  42. SmarterEnu

    Such great work activities. Too bad none work, just like my on off off on on on off off wifi after the upgrade.
    Shame on you Mr. Gatges

  43. Z K

    Another possible resolution, specific to Acer laptops.

    Situation: Aspire laptop, only Win 8.1 supported per Acer website. Fresh Windows 10 install, driver for Atheros WiFi card installed automatically. Cannot turn it on via hotkey or through Windows settings panel. Updating drivers does not change situation.

    Solution: Download QuickAccess (and ePower)! They are like Launch Manager and required for the WiFi switch to work. It will, obviously, not be available for laptops “not compatible” with Win10, but can be downloaded off any other laptop’s section.

  44. Jastria Rahmat

    yes me too

    I spent hours trying to get my WiFi to appear after windows 10 was installed. Then, I simply powered off pc, u plugged pc for 30 seconds. Powered it back up, and there was my Wifi. Thanks!
