Networking :: WiFi Connection Lost After Upgrade From Windows 7
Nov 5, 2015
I upgraded from windows 7 to 10-when finished there was a red cross through the wifi icon.Having read numerous forums,I established that there was no old VPN software;I updated the Broadcom 802.11b/g/n software and in network adapter properties,I unticked power management switching off the adapter;also,altered bandwidth to 20_40MHz.As soon as I clicked on that,the wifi switched on!It then works until the computer is switched off;when on again,same problem.If I go to network adapter properties,and disable and then re-enable the adapter,wifi comes on again.

My PC would be connected to WiFi, but I wouldn't be able to go on any site. I restarted my PC and the damn thing locked up on the HP logo screen! So I had to hold the power button to turn of my laptop.

I have a 3 year old Dell Inspiron 15R 7520 laptop with an Intel Centrino Wireless-N 2230 adapter.
Since upgrading to Windows 10, the wifi connection drops out when using battery power and the only way to restore it is to restart the computer using mains power.
"Allow the computer to turn off this device ..... " is unchecked.
I am not the only one with a Dell 7520 laptop running Windows 10 that has this problem.

I had windows 10, free download, on 25 of August, upgrade from windows 8, and the internet connection was fine till about 10 days ago. Trouble shouting result.."Ethernet does not have a valid IP configuration" . Contacted my provider Talktalk, was sent latest router, can connect with mobile wireless to router, can connect with laptop (Windows 7) hard wired, cannot connect with my desktop (hard wired) on which windows 10 is down loaded.
Have checked cable to desktop by using cable with laptop.
What do I need to do to get connected to the internet with my desktop?

The upgrade from 8.1 went smoothly, the only problem so far is that
I lost my Home Network connection and don't see how to re-connect.
My Home Network consists of 3 computers, an ancient XP, a newer WIN7,
an HP Printer and this one running WIN10.
Where do I find the screen(s) that will let me connect this computer to mt Home Network ?

I just upgraded my desktop to 10 Pro and lost the internet connection. The wireless network appears to be working OK. When I run the diagnostic it produces this message.
"The default gateway is not available"...

I updated to Windows 10 from Windows 8.1
Connection to Internet through Wi-Fi is not happening after that though it is happening via LAN Cable.
Whenever I try to connect through Wi-Fi it gets stuck showing Limited Connectivity and No Internet Access.
I went through some threads and found that it can be solved by disabling "Block Internet Connection Sharing" setting in Bit Defender but I am not using Bit Defender.
I am using Windows Defender instead and am not able to find such setting in that.

There is 2 computers and 2 virgin superhubs in the house i live in (not both mine) both ethernet connected. Occasionally i have to unplug my superhub and connect my desktop computer to the Wifi on the other hub which is in the next room.My computer obviously "remembers" the password for the wifi and i used to be able to just unplug my hub and it would automatically connect to the wifi without me having to do anything.
Since switching to Windows 10, when i unplug my hub, it says that it is connected to the wifi however it says "limited" and no websites work, effectively not connected even though it says it is.To solve it i have to leave my hub unplugged and restart my computer and it connects instantly and works. Whilst that isn't a huge problem, i sometimes could do without having to save what i'm doing just to restart the computer as i have never had to do this before.
The same problem also occurs in reserve if you get me. Disconnecting the Wifi and then plugging in the hub, it also says limited connection until i restart the comp. Virgin Media have been of no support whatsoever, to be honest I didn't expect them to be as it seems like a computer/windows problem.

My laptop is for some unknown reason not connecting to the internet via wifi or ethernet. It will also not diagnose the problem as it says The Diagnostics Policy Service is not running and it cannot fix it.

I was attempting to figure out how to fix my internet connection, and there was an option which said disable, which i thought would temporarily disable my connection and allow me to simply reconnect. i hit that disable button, and all of the wifi disappeared from my laptop. I physically have turned the wifi on and off multiple times, but the internet connections box wont even show a wifi option. i connected with an ethernet to the internet, and it works fine. I don't know how to reenable the wifi on this new windows 10 system, since i just got it yesterday. i am using an older acer aspire 5742-6814 laptop.

I have a laptop with Windows 10, and it has been working fine for months. Yesterday I thought I had a connection issue with the Internet, and set the computer aside until it was resolved. Later I checked my phone, and saw that the WiFi is actually working just fine. I have restarted and reset and tried to connect to Hotspots and all sorts of netsh commands.

After the free upgrade all worked properly, then i did a clean install (format) with a bootable usb that i made from media center. 6 days now no Internet connection, no wifi option. I think its the common problem with Wifi on Wos 10. As you realize i have only the windows files in my hard drive, the driver for my wireless adapter (Airties 2410) and the intel management center driver. I tried everything from the many possible solutions but not luck for me, even installing older drivers for my wireless adapter.

I was upgrading from WP8.1 to W10 and all was going fine but then my internet connection went off for about 1 minute and then back on. Ever since that happened, the phone has been restarting (Nokia logo) and then the cogs are displayed for abt 15 seconds and the phone switches off. It repeats this if the USB cable is plugged in. I cannot use my phone.

I have a brand new HP laptop that came with Windows 10 home installed on it. I have downloaded and applied all updates from MS.
I use a Wi-Fi connection to my Time Warner router. I have everything setup and things seem to be running fine.
Here's the deal.
I thought I would try and use my blue tooth external speaker. (Just to see what would happen.) I enabled Bluetooth.
StartSettingsDevicesBluetooth.
After I move the slider (so the status reads (On), .... I see a message that reads "Your PC is searching for and can be discovered by Bluetooth devices".
Two things happen:
The "search" never seems to end. And I lose WI-Fi connectivity.
I finally, move the Bluetooth slider to the "Off" position and my Wi-Fi connectivity returns.
I "do" see my external speaker. And it does work. (As long as "Bluetooth" is enabled.)
But of course, I then have no Internet connectivity and THAT becomes an issue for me.

Since my daughter (2 years old) switched on airplane mode last week, I'm no more able to switch it off and go back to wifi connection.
No more WiFi / airplane mode icons in wifi window on the taskbar, no more airplane mode option on network settings...
Everything disappeared, apart from the airplane mode icon in the right corner of the screen, which I can not switch to WiFi mode...

I upgraded my ageing Dell Inspiron 530 desktop PC this morning from Win7 Ultimate to Win10 Pro. The PC is connected to the router via ethernet cable.All seems fine in terms of the OS, but I have no internet access. I know the router's OK as my other devices are fine.When I run the troubleshooter it flags up "There may be a problem with the driver for the Local Area Adapter".Digging further, it seems the issue is "Windows couldn't automatically bind the IP protocol stack to the network adapter"
Looking at Services, I found the Wired AutoConfig and WLAN AutoConfig services weren't running were set to Manual. I changed these to Automatic and rebooted, but still no joy.The network adapter is an Intel 82652V-2 10/100 and Device Manager says it's working normally and the driver is up to date.

after upgrading from windows 8.1 to windows 10 I have no internet connection.From looking around various forums the problem is usually a VPN or anti virus issue so I have used the f secure removal tool to uninstall my anti virus and used revo uninstaller to remove hotspot shield VPN from my PC before upgrading with no success. The network connections icon looks connected when the pc is first turned on then it changes to the yellow exclamation mark. I have updated the network adpater driver to the latest and also tried plugging in a USB wireless adapter which has the same problem. Will refresh your pc in windows 10 resolve this issue and does this remove all my saved files?

I have no wifi after upgrading to Windows 10 from Windows 7. Looking at Device Manager, I believe my Network Adapter is Intel(R) 82578DC Gigabit Network Connection. Looking online, I do not find a driver for Windows 10.

I have an Insignia 8" tablet that I use to listen to an internet radio station. WiFi connection to my 2Wire 3801HGV router. I have it powered by the AC charger. I have the display to turn off after 5 minutes, never to go into sleep mode when powered by AC. After the 5 minutes the display is turned off, the music continues as expected and will continue for hours. But if I try to do anything I loose my WiFi.Right after the screen is shut off I can enable it again with a stroke. Then the music stops. I no longer have internet access.
Network settings says I still am connected but somewhere the connection is broken. I disconnect from my router and then try to reconnect and it will not. I get, Checking Network Requirements, Can't connect to this Network. The only way I have been able to get connected is to do a restart. I have not found any settings that have been useful. All it should be doing is shutting off the screen. Not go into any other sleep or power down state.

I upgraded my friends HP laptop to Windows 10. The issue now is I can't enable Wifi. The card is recognized correctly in Device manager and no issues is found with it. It looks like it is fine. However in the Network Settings WLAN is set to "Off" and when I try to turn it on it always jumps right back to off. eg. I can't enable it.
HP clearly state any laptop bought prior to specific date in 2013 will not get any driver updates from their side for windows 10. And updating through device manager only tells me it's the newest driver available.
The Wifi card i Broadcom 4313GN card. I searched for win 10 drivers but did not find anything.They only offer linux drivers on their homepage...
So any solution to the issue or link to a win 1' driver for this wifi card?

I have a Chuwi Hi8 tablet. Yesterday I upgraded the preinstalled Windows 10 RTM to the latest build 10586.104 and got the well-known Wi-Fi Not Available problem.
When I open the Device Manager, I see no problems with the installed hardware. Windows reports that all drivers are installed and work correctly. The same concerns the Broadcom 802.11n Wireless SDIO Adapter.
The website of the device (URL...) does not work a lot. They do not provide a driver package I can use to reinstall the drivers. I even can't register on their forum to request the driver pack.

I upgraded mu Alienware M14 from 7 to 10 using the Media creation tool, and now have no WiFi. Ethernet and Bluetooth both show fine, and a wired connection works perfectly, however, not being able to use WiFi puts a damper on the portability of said laptop.
I've tried the reg delete method, which informs me the key is not found, there was no VPN software installed. I do show a network adaptor under unknown devices, but no matter which driver I choose, it is unable to start. Short of a clean installation, and the loss of personal files and/or hours restoring them or reinstalling.

After the upgrade I performed a "Reset this PC" with "Keep my files". Periodically the WiFi will die. No networks will appear in the list in the pane which appears when one clicks the icon at the bottom right.The fastest way to fix it is to click the left-most button twice, which seems to disable/re-enable and automatically reconnect to the network. I have checked the router. The problem is not manifesting on another Lenovo laptop upgraded the same way. I am using the latest available network driver.So far I haven't performed a clean install due to the time it will take.
