    Have you guys tried the "Show hidden devices" in device manager?
    Yes, I tried that as well, all 3 adapters that I need are missing (ethernet, wifi & bluetooth)

    Acer has some wifi/bluetooth chips where the manufacturer of those chips have not updated their drivers. Check out the driver's download site and you'll probably find that they had no idea that Windows 10 existed. I´m not at home now so I can't look up the manufacturer for the chip now but Acer's site will state what models support Windows 10. For those models not on the list, well, we'll have to wait and see if they will be added if and when the driver's manufacturer updates their software.

    I'm not as tech savvy as tall. I upgraded to windows ten and my network adapter isn't working. In the bottom right corner where networks are usually listed it says "not connected-connections available" but when I go to search for networks it won't recognize any.

    My drivers have been uninstalled reinstalled and it shows up in devices. If I got into wifi options it shows networks that I can approve or decline, however it won't let me connect to the Internet...

    Hi There.

    I have the similar issues, apart from the Wi-Fi seems to sometimes work and then just disappears!!
    Really annoying....

    I am running a Dell M3800 with a clean install of Windows 10 Pro x64.

    The info below seems to have worked for my issue thus far.......
    Steps that I have taken include:
    : Disabling "Allow the computer to turn off this device to save power" from the device settings (Device Manager)
    : Edited the Power Plan from control panel and set the 'Wireless adapter- power savings' to "Maximum Performance"
    : Edited the Power Plan from control panel and set 'PCI Express Link- State Power Management' to "OFF".

    This appears to have resolved the issue so far.
    The WiFi was switching itself off after around 20 minutes to an hour, but 2 hours in and seems to be stable.
    Will let u know if anything changes.
    Good luck....

    Wireless Network Adapter disappeared after Windows 10 upgrade


    Mine was fixed by the same as Robbie (quoted below). I went into Device Manager and deleted the driver for the wireless device, then restarted the PC. However, the PC wouldn't restart without my first attaching a live Ethernet cable to the PC. Once I did the driver was installed automatically, and the PC booted fine.

    I had the same problem with my WiFi tab disappearing this morning. I just went to Device Manager>Network Adapters and uninstalled/reinstalled the driver for it and it came back and it has been working fine since. I'm even using it now. Hope this helps and let me know if this suggestion works for you. Have a good evening! :) - Robbie

    I had the same problem, my WiFi was missing from Network and Sharing, and disappeared from Device Manager. I tried several solutions I searched for, none of them were useful seeing as the driver was missing from Device Manager. I assumed the WiFi adapter just broke. I didn't try reverting back to Windows 8 or anything, I tried restating several times, was still missing. Finally I decided to just shut my computer down and go to sleep. The next morning I turned it on and surprisingly the WiFi appeared in Network and Sharing, and was recognized in the Device Manager as well. WiFi still didn't work so I just downgraded the version of the driver in Device Manager and everything worked again. WiFi was missing after a Windows 10 upgrade just like happened to you. But looks like it fixed itself after just shutting down and letting it rest for a few hours.

    I have similar kind of problem except that after upgrading to Win 10 wireless was working fine; let me tell some history and symptoms.

    It started when I noticed there is a big delay when I want to open network and sharing center and change settings, such as dns server. I tried many solutions I saw on web: virus scans with various antivirus software; trying a repair with sfc/scannow command, resetting tcp/ip protocol etc.; finally decided to reinstall the wireless adapter driver.

    The worst part started after, even though I reinstalled it back, and even tried a newer driver, I cannot connect any more over wlan. The point is not the driver; in device manager it shows that the driver is installed and the device is working fine. However, the “hp wireless assistant” says that, when you turn on wifi in it, “it is disabled in the device manager and should be re-enabled there” (I repeated this enabling/disabling several times). The wireless adapter icon in the “network and sharing center” disappeared, so did wifi settings under network section. The connection icon on the right of the taskbar now says there are no active connections (there are). In short, the system somehow “lost its wlan capability”. Some other info that could help in diagnosing: I tried an external wifi adapter to see what happens; even though it seems to be installed in device manager correctly, like the internal one, it doesn’t work. I tried going to safe mode and un/reinstalling drivers. I have connection over ethernet cable. I haven’t installed recently (just before this problem started) something suspicious like vpn or antivirus software, I have always used Microsoft’s security essentials.
    It will be so difficult to make a clean install for me at the moment, and even I’m not sure whether it would fix the problem; so I’d appreciate if someone could offer a way around.

    Ok guys well I have figured out the issue windows has a fast startup option in it power management so what this does is throws everything into sleep mode to get it back is what I did if you have a laptop is unplug the laptop hold down the power button for 10 secs to clear the sleep mode did this twice to make sure. After doing so i started windows back up imagine that windows took longer to load so i came to another option to my wifi adapter to never go into sleep mode which fixed it you can also go in the power options and turn off the fast startup. You go to control panel>hardware and sound> power options now in this click on the left where it says choose what i do when i hit the power button. Down at the bottom there are shutdown settings that are grayed out click on the change setting that are currently unavailable. They will now become ungrayed and uncheck turn on fast startup this should solve your issues. This should also work for anything that is wireless i.e. going into airplane mode or not seeing wireless bluetooth.
