Windows 10: WiFi suddenly not working

I was browsing the internet on my PC earlier and the connection kept going on and off. I assumed it was some problems on my ISP's end, so I turned my phone's hotspot on and attempted to use my cellular data instead. It refused to connect to my phone, and now will not connect to my home WiFi either, but my laptop and tablet are next to my PC and connect to both fine.

When I click "Connect" on a network it says "Connecting..." then all the WiFi networks disappear, then they all reappear a second later and it says "Cannot connect to this network". When I hover over the WiFi icon it says "Not connected - Wireless communication is turned off". I have checked the settings and it is not turned off.

I have tried troubleshooting with no help. I have also tried enabling/disabling and uninstalling/reinstalling the WiFi driver. Network Properties says:


Name: Wi-Fi

Description: Dell Wireless 1707 802.11b|g|n (2.4GHZ)

Status: Not operational


Does anybody have any ideas?


Thanks.

Wifi suddenly stopped working - strange result


Wifi stopped working suddenly on my desktop. Now I have to connect with cable to the router but when I open Network Connections it still says the wifi is connected and working. The Ethernet connection has the name of the Wifi SSID.

If I open the details of the wifi connection it says there is no0 IPV4 or IPV6 connectivity although these are checked.

What has happened?

 

Wifi suddenly stopped working - strange result


Hi I recall that while my PC was on over lunch I returned to find those protocols had suddenly and without apparent reason vanished.

Why? Hmm, maybe there's a clue in your event log. Sorry, my crystal ball is down for scheduled maintenance*chuckle

Easy option (hopefully), avoiding use of a possible series of commands:
Download and install Tweaking.com's repair tool (free), lots of cautious stages beforehand. Observe accordingly.
Select ONLY network connection repair.
Run the repair.

If that doesn't work, here's a set of instructions for repairs:

1. Run the built-in Troubleshooter

Right click the network icon on the Taskbar
Pick Troubleshoot problems
Select Identify and repair network problems
Follow instructions in the troubleshooter

1. Reset networking

Launch Command Prompt (Admin)
Copy the lines in the code box below
Right click in the Command Prompt window to paste
Code:
netsh winsock resetnetsh int ip resetnetsh int ipv4 resetnetsh int ipv6 resetipconfig /renewipconfig /flushdns
Restart your machine

1. Disable IPv6

Open Network Connections
Right click on the affected adapter(s) (Wifi, Ethernet, or each one of them)
Select Properties
Scroll down to Internet Protocol version 6 (TCP/IPv6)
Remove the check mark
Press OK

Restart your machine

1. Reinstall TCP/Pv4

Launch Command Prompt (Admin)
enter the following command
netsh int ipv4 install
exit

Restart your machine

1. Restart Your Network Adapters

Open Network Connections
Right click the affected adapter(s) (Wifi, Ethernet, or each one of them)
Pick Disable

Restart your machine

Open Network Connections
Right click the affected adapter(s) (Wifi, Ethernet, or each one of them)
Pick Enable

The tutorials provided are just a list of troubleshooting steps. Use only the steps which apply to you.

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.
