Windows 8.1 preview - No WIFI

    Question

  • I installed the Windows 8.1 Preview and now my "802.11n Wireless LAN Card" does not show any wifi signals to connect to. I have it hooked up with an ethernet cable right now which works fine. It also uninstalled my Avast antivirus. The last thing to uninstall my antivirus and disable my internet was a malware.

    HP Pavilion p7-1414, AMD Quad-core, 6g RAM, 802.11n Wireless LAN Card

  • It is supposed to uninstall the antivirus and leave Windows Defender to do security. I will assume then that it is intended to disable the wifi. I did not see any warnings about this pre-install.

  • Same problem - no WiFi signals. I attached a router configured as a client to access my wireless network. While configuring the client - the internal WiFI started working! After rebooting - WiFi gone again :(   My guess is it has something to do with the new Wireless Hotspot features predicted to be in the final version.

    Thursday, June 27, 2013 4:21 PM
  • Same boat here with my Toshiba. Realtek adapter is enabled and up to date but nothing until I plug it in to LAN. Hoping they come out with a patch really soon since I like the new features

  • Same problem with my SurfaceRT.

    IT sees no net or claims password is invalid even if i try to connect to an open net. 

    It worked perfectly with 8.0 and other devices can connect so in my case it's the surfaceRT or 8.1 that is the root of the problem

  • Same here, i tried enabling the adapter in Control Panel > Network and Internet > Network Connections once i click Enable, it first says Enabling followed by Enabled. But it still wont enable it even tho it says that it does...

  • Same, Realtek RTL8192DE wlan card. Go to properties in device manager. Find this under device status.

    "This device cannot start. (Code 10)

    {Operation Failed}
    The requested operation was unsuccessful."

    un-installed drivers, installed latest from realtek website. still nothing.

    Control Panel - Hardware and Sound - Device Manager (Under Devices and Printers) - Arrow in front of Network Adapters - Right click on your Wireless card - Update Driver Software - Browse my Computer - Let me pick from a list - Pick a driver you think Microsoft is going to like, and if it doesn't work go back and pick a different one.

  • Hello Guys had the same problem and I've been searching the internet behind the solution, I finally found the solution to my Notebook which is a Itautec infoway note N8510 and uses the wireless network card Realtek RTL8723AE the solution was as follows:
    1 - Device Manager
    2 - Network Adapters
    3 - Select the device related to your wireless card
    4 - Click the Right button on the selected driver and Click Update
    5 - A window appears, click the Browse my computer for driver software
    6 - You will see another window, click let me choose a list of device drivers on the computer and displays a list of available drivers select another driver in the list
    7 - Click Next and go!!
    Now make sure you are capturing wifi networks
    this was the solution I found to my computer using windows 8.1 upgraded the store!

  • I've been running 8.1 for about a day on a desktop system. I installed 8.1 Preview using a wired connection. After installation I tried installing an older Dynex card (uses a Broadcom chip). I downloaded drivers from Dynex (I assume they were Windows 7 drivers), and at first the card worked. Later after reboot it would not connect to my router.

    I then tried a USB Linksys AE2500 adapter I had available. Same drill, but this time the installation worked and I'm now using it instead of the Ethernet port.

    The system reacts differently than older versions of Windows in that there's no "hardware wizard" to give you thumbs up or down. I have yet to test with other hardware but it's like PnP is dead.

    OK, I just saw the Brazilian student's fix above. I had uninstalled the Dynex driver and the adapter disappeared from my hardware list. However, when I "scanned for new hardware" the Dynex adapter showed up but this time it's listed as "Broadcom 802.11g Network Adapter" and seems to be working. So we'll see how it goes. Maybe the installation of the Linksys driver helped the Dynex to work?

I have a Toshiba Satellite. i went into  DEVICE MANAGER > NETWORK ADAPTERS > REALTEK WIRELESS LAN > UPDATE DRIVERS > BROWSE MY COMPUTER > LET ME PICK FROM A LIST OF DEVICE DRIVERS ON MY COMPUTER > (then picked the driver with "(Realtek semiconductor Corp.) at the end of it)

    NOT the one with "(Microsoft)" on it.

    This worked for me.

    I have reintsall the Windows 8.1 preview deleting all installed apps , but not my personnal data.....

    When  it's installed the WIFI is still not working , so i''ve do this:

    -Control Panel - Hardware and Sound - Device Manager (Under Devices and Printers) - Arrow in front of Network Adapters - Right click on your Wireless card - Update Driver Software - Browse my Computer - Let me pick from a list

    by chance (i think) there was two Adapter compatible : one of them doesn't work but the one work!!! so try it !! Don't forget to choose wheen you istall Win 8.1 to  delete all installed apps (it will disturb the new system)!
