Wireless network failed

Hello everyone.

I got in trouble now.

Firstly I found I cannot open start menu with clicking the icon nor pressing win key. Since I can shutdown pc with cmd so I didn't care.

Then I found I cannot connect to WiFi.The WiFi around won't be shown on the tab.And I cannot open the action center neither.I managed to reach the setting of wireless network by entering Control Panel, going to "Network"option and clicking "Connect VPN",and toggling to wireless network card.There was no available WiFi shown though I have many WiFi hostspots here.

My windows version is 14393.I have installed it before,and met such question.But after a restart it come to work.

I have checked the drive and it shows good.

It means good.

Also I check the system


This is Chinese and it says no difference and no error.


Yeah,I have installed VM.I installed Kaspersky as anti-virus software.
Emm,I have moved the user folder to disk E while I installed this time.

I am really puzzled and would you like to help me?
============================update==============================

I may find the cause of the bug.


According to https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

this represents "The task has not yet run."

Any help would be appreciated.


I shall try this first

Hi RochustCN

This looks like a very old adapter, last updates on Intel's site is for XP in 2012. You may find upgrading the Wireless Adapter in your machine or buying a USB Wireless dongle will provide you with improved stability and speed.

If you wish to attempt fixing I would create a restore point.

I would start with reset your Network within Windows 10. Click Start => Settings => Network and Internet. Bottom of right hand window, Reset Network. This will cause you to loose all wireless passwords.

I would then power down router, wait 20 seconds and power on.

In the advance settings of your power plan I would go to the Wireless adapter settings for battery and plugged in and ensure they are set to maximum.

Then open Device manager, find your wireless adapter, right click, then properties. If there is a power management tab remove the check mark that allows computer to power this device down to save power.

Some people have found disable IPv6 helps. Here is a link to a Microsoft site. Use left most option. You can see it can be enabled just as easily.

You may also want to see the networks around you to see if a new one is now causing interference. Ideally you want your network to use a channel that no one else is using. That isn't that realistic. As such pick one where the other networks are weakest.

inSSIDer 3.1.2.1 Download - TechSpot

Depending on how far away you are from router you will get better signal with the 2.4Ghz network or better speed with the 5. Pick 2.4 for stability. You also don't want to be using WEP security protocol.

You may also shut off WifiSense and the other option below it for connect to opening networks. Click Start => Settings => Network and Internet => Wifi. Then in window on right scroll down to WifiSense and shut it off as well as the two options below it.

Also watch router placement. It should be in the clear and should not be located near devices that create electrical interference / noise. (Cordless phones, Microwaves, transformers)

The simplest and cheapest thing to do is buy a wireless dongle.

Newer technology, better speeds and current support. Some are quite small and very effective.

I have updated:the WiFiTask has not yet run.

How could you confirm that wireless adapter failed?

Interesting question as we seem to be dealing with more of a software failure and I use the term "software" very loosely.

If you run that inSSider tool I provided link to and it runs solid, that is it shows you your networks and others around you, you could have some confidence that the adapter is working. However as this is drivers and protocols being used between laptop and router the tool won't show you what is going wrong. There are tools for that but as you can't modify drivers easily you are just spinning your wheels.

One other thing you could do to prove system. Download and burn a cd with Ubuntu on it. When you use the cd do not install it to your hard drive. It has an option to test drive Ubuntu from CD. It is pretty robust and will likely install everything you need to to test drive. It comes with Firefox. You could do some surfing. I'm very sure Wifi will operate very well. This would confirm it is a Windows "software" issue. If Ubuntu doesn't work either it would confirm adapter is shot.

Please don't install Ubuntu as it will modify your boot records, just test drive.

If machine is just for surfing and you like Firefox or Chrome, Ubuntu is free. It is quite easy to use and could be installed permanently.

Well,I'm really grateful for your support.

It's proved the wireless network adapter is OK.

It costed me two days to repair the registry which was broken by following the solution I mentioned.It always informs me that "Not all data was successfully written to the registry. some keys are open by the system or other process, or you have insufficient privileges to perform this operation."

when I googled it ,I could find none but repair installation.Someone says I may edit the registry by PE.

When I tried safe mode and wanted to add key,I was mentioned with "you do not have permission to create a new key".When I googled this sentence,I find answer.

Today I repaired it and someone advised me to create a administrator user and try it.When I log in using this account,WiFi is available.I still don't know the bug.

Thank you again.

Depending on how much software and customizations you've done it may be easier to do a Clean install.

This would give you a new registry and should resolve your start menu issues. So people dread a clean install due to customizations, licensing keys etc.

Should you decide to perform there is a solid tutorial on it.
