Fix Windows 10 WiFi Intermittent Disconnects Problem

Recently we have used the free upgrade offer from Microsoft to upgrade Windows 8 to the latest Windows 10. Well, the installation was quite smooth with few restarts until we struck up with the first issue. The laptop was not able to connect to the wireless (WiFi) network. After fighting hard to install the latest driver files for the network adapter, finally we could able to connect to the internet through WiFi. It did not last long as we struck with the second issue. WiFi was dropping frequently and there were no proper solutions to resolve the issue.

In this article we would like to share all those things we tried to resolve the WiFi connectivity issue.

Fix Windows 10 WiFi Issues

Internet Not Connected

When you have problem with wireless connection, first check whether you can connect to internet by opening a website in Edge or other browser you use. If you notice WiFi icon on the system tray shows a warning with limited or no internet connection then check this article on how to fix this issue. Try the following solutions to ensure you have working internet connection.

1. Run Windows Network Diagnostics

Windows 10 offers a handy option to troubleshoot network related issues. Simply right click on the WiFi icon on the taskbar tray and select “Troubleshoot problems” option.

This will open Windows Network Diagnostics and the system will automatically start detecting the network problems on your PC. Most of the time, this will help to fix wireless related issues. You can also view the detailed information to get the troubleshooting report like below.

2. Network Adapter Issue

When you noticed your PC could not connect to wireless after Windows 10 upgrade, the most possible reason is the network adapter. Follow the below steps to fix this issue:

  • Right click on the “Start” menu and choose “Device Manager” or use the “Cortana” search box next to “Start” menu and open “Device Manager”.
  • Find out the adapter used on your PC under “Network adapters” section.
Check Network Adapter in Device Manager

  • In our case it was “Intel(R) PRO/Wireless 3945ABG”. Go to the provider’s site and download the latest driver file for Windows 10.
  • Uninstall the old driver and install the newly downloaded one.
  • Click on the “Scan for hardware changes” to re-enable the adapter with the newly installed driver.

This should resolve the problem of connecting to the wireless network.

3. Switch Off Airplane Mode

Windows 10 has an option to switch off wireless connection using quick “Airplane Mode”. Click on the WiFi icon on the tray and check your “Airplane Mode” is disabled.

WiFi Connection Frequently Dropping Off

It took few days to realize that the WiFi connection was dropping off frequently due to the problem in laptop. Since we use VPN it was the first suspect and the router being the second one. As the same VPN and router were perfectly working with the iPhone, we were forced to look into the Windows laptop for clue. When looked into the “Events Viewer”, it confirmed that the network was dropped off frequently with the error message “WLAN AutoConfig service failed to connect to a wireless network”.

At beginning we have tried the following steps:

  • Restart the laptop, router and reset VPN settings
  • Disable and enable wireless connection
  • Troubleshoot the wireless connection
  • Disable Windows Defender
  • Check “Task Manager” to see any programs are causing the issue

None of these worked out and the problem returns back intermittently. It was time to dig the issue deeper and below is the list of options we tried to fix the issue. For us, finally the option 2 worked out and we could successfully connect to WiFi without dropping off.

Option 1 – Disable Network Discovery

Open “Network and Sharing Center” and click on the the wireless internet connection you are using.

Click on the “Wireless Properties” button under “General” section which will take you to the properties of your wireless connection. Disable the option “Look for other wireless networks while connected to this network” under “Connection” tab.

Note: SSID is the name of your wireless connection, ensure to have a unique wireless connection name for your router to avoid confusion.

Option 2 – Adapter Power Management Settings

Open “Network and Sharing Centre” and click on your wireless connection name. This time click on the “Properties” button under “Activity” section.

Change Power Settings of Wireless Adapter
Change Power Settings of Wireless Adapter

You will be taken to “Wi-Fi Properties” popup and click on the “Configure” button for your wireless router connection. The next popup will show the network connection properties of your wireless router and disable the option “Allow the computer to turn off this device to save power” under “Power Management” tab.

Option 3 – Disable IPv6

IPv6 addresses are introduced with the depletion of IPv4 addresses and currently both IPv4 and IPv6 are used by most of the services. You can give try by disabling IPv6 connection under your “WiFi Properties”.

Warning: Disabling IPv6 will affect accessing certain websites available only through IPv6 and also you may not able to create workgroup.

Option 4 – Restart Computer Browser Service

Right click on the Windows taskbar and click on the “Task Manager” option. By default the “Browser” services will be in a “Running” status which can be seen under “Services” tab. Right click on the “Browser” service and “Restart” it.

Option 5 – Tun Off Bluetooth Discovery Mode

If you have enabled Bluetooth on your laptop, navigate to Bluetooth settings and click on “More Bluetooth options”. Then disable the option “Allow Bluetooth devices to find this PC” under “Discovery” section.

Conclusion

We have looked into all those Microsoft and other popular forums and it is clearly evident that the wireless connectivity problem is something to do with Windows and not related to the router. Unfortunately the issue is not addressed with any appropriate solution. Though option 2 worked for us, you may need to try out different options to make the WiFi connectivity stable.

  1. Power management . . . . . . . . my bluetooth mouse would disconnect all the time. Finally figured out it was the power management setting. Now wifi intermittantly goes off. Can’t believe that I did not think to check power management. Thanks for the clue . . . and the solution!

  2. New PC came with Windows 10 and I’ve been using a wireless dongle. I’ve been experiencing these wretched drop outs as well. Thank you for putting this very helpful list together. I’ve gone through all of them, and now appear to have a stable internet.

  3. I have the same win10 wifi issue with my laptop. I tried all these options but none of them works. Occasionally I found, if I turn on airplane mode for a few seconds and then turn it off, the wifi will work for a relatively long time. Try it if other ways all failed.

  5. I have a Toshiba S55 with Windows 10.

    After an hour I have booted it, it is impossible to work. Continously disconnects from my local wifi and cannot see mi wifi to reconnect to it. I have to disable/enable the adapter several times to reconnect and keep an stable link.

    Meanwhile my cheapest cell phone and other toshiba with Windows 7 that I have, are working perfecly.

    In my opinion, it is a bug.
    I have the lattest drivers, change from DHCP to fixed IP address, execute a lot of network commands, and reinstall W10. Nothing works!!

  6. Hi, after a month of fighting with dropping wifi, reinstalling system, bios, wifi card etc I solved issue by… installing card driver that had been released on 01.Nov.2017!!! My wifi stopped working on October,12 this year and now it is working. So, my suggestion is. Try to install drivers one by one starting from the newest.

  7. Most of these fixes work only if your connection is stable enough that you can complete them before losing the connection. In my case, I have about 5 seconds before the connection is lost again. Can any of these be done in those few seconds that I’m connected? Or is there a way to modify them without the connection being “live”?
    I have the most recent update for the wireless driver. All my other devices work fine (but they’re all iOS and macOS).

    • You can try almost all the above fixes without connecting to internet. If the problem persists, it could be on your Windows OS and not on the wireless adapter. So you can contact your computer support or try repairing Windows 10.

  8. I tried all of these methods and none of them seem to work for me, it doesn’t even decrease the amount of times it drops out. Do you have any other solutions I could try? My laptop is brand new only a few days old and it started happening all of a sudden, I had no issues the first two days.

  9. Good morning Sir,

    Thank you for the detailed instructions. Unfortunately, nothing worked for me.

    In option 4 the “browser” by default is stopped. Any idea why?
    When i try to start it, it goes back to stopped after a while.

  10. Option 2-power management helped reduce the drops. But new occurrences of dropping have started to show up. My other laptop (win7) stays up, so I am trying turning off IP6 (thanks for the screenshots to get to that rabbit hole). Although I suspect, I need to turn off Bluetooth as well (running WiFi connected to phone).

    Thanks for building such a complete list, with thorough instructions.

  11. Thanks so much!

    My issue related to Bluetooth Discovery Mode – After 3 days of frustration, Wi-Fi has been up for nearly 24 hours now – thanks for your information and help.

    • The wireless driver has to be repaired at each restart of the laptop, with the Intel ProSet app. It disappears at each restart.
      After the repair it works fine, no disconnections. very unique problem. any solutions please?

  12. I have installed Intel PROset/Wireless software v. 19.20.00 and after running it to repair driver the wireless showed up again and worked. Only when IU reboot it is back to the same fault, no wireless showing and have to run the repair software again every time before I can have a wireless connection active. Any permanent solutions? This has also started with the installation of the anniversary edition of Windows 10 on a brand new lenovo thinkpad E570 just unpacked.
    Another issue is the Hello setup, the software opens a small black windows for a couple of seconds and then it fades aways, not allowing me to setup the fingerprint sign in option.
    Thanks for the help you can provide, if any.

    Best regards

    Pedro

  13. Your tutorial is very useful and provides another way to fix Windows 10 Wi-Fi issues. As for me, I used a way which is based on a program to repair Wi-Fi stop working on Windows 10.

  14. I followed the steps to update the wireless driver but failed. Then I used Driver Talent to update and I made it. After reboot, the problem was gone. Thank you for your instruction. You listed the detailed guidance with step-by-step. You are so patient. Thank you again.
