No-WiFi-on-Windows-10-Dell-SystemsOverview: There is a high number of Windows 10 users who are facing no Wi-Fi issue. There are multiple reasons for the Wi-Fi not working. Today in this post we will troubleshoot Wifi issue and will get the Wi-Fi working on Windows 10. Troubleshooting applies to all Windows 10 users including non-Dell users.

So, let’s start with real user’s practical scenarios!

Scenario 1: WIFI Options Are Available, But Dell Is “Not Connected” And Won’t Troubleshoot To Find Networks Or Connect To WIFI At All

My Dell XPS 12 was working normally and my connection to any wireless network was just fine till it randomly “turned off” the WIFI Networks option and started showing absolutely no possible networks for me to connect to when I know there are a ton. Last night when I right-clicked the WIFI icon in the taskbar it did the troubleshooting just fine and got my WIFI Network list back up so I could connect to my router just fine. When I tried troubleshooting this morning, it says, “Troubleshooting couldn’t identify the problem.” I’ve gone to “Explore additional options” but none of the supports have worked. They tell me to select Start, then Settings > Network & Internet > Wifi to see the list of networks, but that’s not working. It’s not on Airplane mode and I’m not sure if this laptop has a physical WIFI switch to turn on (I’m not even sure where the indicator light is for me to check). I do not know what the problem is and I can’t figure out how to solve it :/ Thanks in advance. Please, let me know if you need to know any further information so I can fix this problem.

Scenario 1: Dell Wi-Fi Not Working

I have a Dell Inspiron 15r 5521. I am facing issues with the network driver. Currently, my wifi is working properly, but after a few hours, it stops working. A small yellow sign comes on the wifi icon. When I disconnect the wifi and try to reconnect, I cannot find any wifi networks to connect with. I have to restart my laptop every time this happens. During the restart, it shows a blue screen stating power_state_driver_failure. I have tried to uninstall the network driver and reinstall it. In the network panel, my ethernet port shows disconnected. I have been facing this issue for last 1 month. Kindly help.

Like the above two users there are multiple users who are facing the issue with the Wi-Fi, let’s go ahead and fix this.

Solution 1: Perform Hard Reset

Most of the time hard reset fixes the issue. Unplug all external devices from your computer. The only devices you should leave connected to your computer are your monitor, mouse, and keyboard if the computer is a desktop. Now Shut down your desktop and unplug the power cable from the desktop.

In case of laptop unplug the charger and remove the battery if applicable.

Now press and hold the power button down for approximately 15-20 seconds then plug in the power cable back to the desktop. Plug in the battery and charger back in case of laptop and start the system and try connecting the Wi-Fi. In case the issue still persists move on to the next step.

Solution 2: Switch on the Wi-Fi

Sometimes you never know that Wifi has gone off accidentally by pressing Wi-Fi key on the keyboard. In Dell Systems press F2 or Fn + F2 or PrtScr or Fn + PrtScr whichever is applicable to turn off and turn on the Wifi. Switching on the Wi-Fi may fix the problem. If the issue still persists move on to the next step.

Solution 3: Run the Windows Network Troubleshooter

Make a right click on the Wi-Fi icon located on the bottom right of the screen and click on the troubleshoot problems.

The Windows troubleshooter will identify and troubleshoot the issue. Restart the system, most of the times it fixes the problem.

Solution 4: Perform Power Cycle with Router and the System and Check Other Systems

First, check if the Wi-Fi is working fine on other devices. If the Wi-Fi is not working on any of the devices then it might be an issue from the Internet Service Provider (ISP). Please contact your ISP.

If the Wi-Fi is not working on any particular system then the issue is with the system.

Shut down your PC and then shut down the router/modem. Unplug the power cable from the router/modem, wait for 60 seconds, plug in the power cable back to the router/modem and wait till all the lights are up and running on the router/modem. Now restart your PC and try connecting to the Wi-Fi.

Solution 5: Flush the DNS

Type cmd in the Windows search box and then make a right click on Command Prompt to Run as an Administrator.

When the command prompt opens, type ipconfig/flushdns and press Enter.

Type netsh int ip reset and press Enter.

Reboot your computer and connect to the Wi-Fi.

Solution 6: Update or Install Network Driver

In case there is a yellow bang or red X on the Wi-Fi icon then driver installation/update can fix the issue.

Go online if you have an ethernet cable to connect to your PC and install/update the Wi-Fi driver. If you do not have ethernet cable then use another PC to get the driver on the USB flash drive/storage device and then install the driver on the faulty system.

Solution 8: Perform System Restore

If you think that after installing some driver, updates or installing any app might have caused Wi-Fi issue then you can restore your PC from a system restore point. Restoring your PC undoes recent changes made to the PC.
