    Wifi adapter not working! (Windows 10)


    I was trying to change the mac address of wifi adapter. But i accidently chaged the tcp ip. The moment i changed it, wifi adapter just disappered from controlpanel/network and sharing center/network adapters. I also looked at device manager and saw that my wifi adapter had warning sign. In the description of device it says it doesnt work properly and also code 31. I changed my tcp ip back to normal but it still doesnt work. What shall i do !!!!!!!!
    My network adapter: realtek rtl8188ftv wireless lan 802.11n PCI-e NIC

    :)

    Wifi adapter disappears - goes 'hidden'


    Running Windows 10 on an Acer laptop. Over the past month, the wifi connection dropped without explanation/warning.

    First time, the adapter was visible in Device Manager (with a yellow triangle next to it). An interent search found the suggestion to uninstall it and restart. That worked.

    Today, the connection dropped again. In Device Manager at first I could not see the wifi adapter listed. I clicked to see hidden devices and found the adapter and the Bluetooth (which I had not noticed was missing).

    I again uninstalled, restarted, and both the wifi and bluetooth have returned.

    Anyone any ideas as to what is happening, why it's happening, and what I need to do, please?

    I have attached a screenshot of the DM windows as it is now, showing the wifi adapter name, etc.

    Thanks very much

    Problems when sharing WiFi with the Virtual Adapter

    For many years I have always shared Internet to my devices like phone and tablet with my PC's WiFi antenna through the Microsoft Wi-Fi Direct Virtual Adapter, I only use it for that, since I have a cable connection, and I start the wifi with the command NETSH WLAN start hostednetwork previously having done the settings of NETSH WLAN set hostednetwork mode=allow ssid="Wifi" key="password".

    For my devices to connect it is necessary that the Virtual Adapter that is created with that command has access to the Internet, for this I have to share the Internet from my Ethernet adapter to the Virtual Wifi adapter.

    For some time now (a couple of months) I've been experiencing problems when sharing the Internet through that medium. The problem is that when I start the WiFi my devices do not connect, they say "Getting IP address" and never connect.

    I have found the solution and I have to do the following:

    1. Disable the Virtual Adapter with the command netsh wlan stop hostednetwork.
    2. Remove the connection sharing from the Ethernet Adapter.
    3. Activate the Virtual Adapter with the command netsh wlan start hostednetwork.
    4. Adding connection sharing from the Ethernet Adapter to the Virtual Adapter again.

    By doing these steps my devices can now be connected to the Wifi, but sometimes it doesn't work if I do these steps too quickly. I have noticed that if I do step 3 and 4 too quickly it does not work and I have to repeat the process but doing these last two steps more slowly, until the Virtual Adapter gets an IP address 192.168.137.1 from Internet Protocol version 4

    Also this problem does not occur 100% of the time. Sometimes when I run the command to start the Wifi everything happens fine and my devices connect well but this only works after my PC has been on for at least 5 minutes (I haven't counted it). If I run the command as soon as my PC has turned on then it doesn't work anymore.

    As I mentioned before this problem didn't occur before because I had configured a .bat file that ran as soon as the PC was turned on with the NETSH WLAN start hostednetwork command and everything worked fine.

    Now, I would like to go back to before when everything was fine so that when my PC starts up the WiFi too and I don't have to do all this protocol all the time, but with a simple command everything is solved.

    Could someone give me a hand with this?

    Hi,

    Thank you for posting your query in Microsoft Community.

    I understand your concern and will assist you to resolve this issue.

    I suggest you to follow the methods below and check if it helps.

    Method 1: Windows 10 has a built-in troubleshooter to check and fix issues with Internet connection. I would suggest you to run this troubleshooter to check if the issue

    Refer these steps:

    • Press Windows key +X, select Control panel.
    • Change the view by option on the top right to Large icons.
    • Click on troubleshooting and click on the view all option on the left panel.
    • Run the Internet Connection troubleshooter and Network Adapter troubleshooter.

    Method 2 : If the issue persist I suggest you to uninstall and re-install the drivers and check if it helps.

    Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.
