Hi all, so this issue cropped up yesterday, where the network adapter (Marvell AVASTAR) just disappeared from my device list. I know SP3s have a lot of issues with adapters, but I can't seem to find anything quite for this.
I've tried rebooting, refreshing, and factory resetting everything. It seems to be a driver/detection problem - there's no adapter listed in the device manager, though there is an entry for an 'Unknown USB Device (Device Descriptor Request Failed).' I've tried uninstalling that, uninstalling and reinstalling the drivers, adding the adapter as legacy hardware, and switching up that order. One time it was detected and working, but it stopped when I rebooted. With the adapter added through the Add Hardware wizard, I'm able to see the proper entry in the device manager and the Unknown USB Device entry is gone (usually, it still shows up sometimes). It still has that yellow exclamation mark with it, giving a Code 31 error (Windows can't load the drivers required for this device).
Also, I'm not totally sure I'm attempting to install the drivers properly. I'm using the downloads from the microsoft website (https://www.microsoft.com/en-us/download/details.aspx?id=38826), but I'm still second-guessing what I'm doing. Because the Windows version is 8.1, I figured I should install the Surface Platform Installer (SurfacePro3_Win8x_151026_0.msi) but when I go to use the device driver installer, it just says it wasn't able to find drivers for my machine. I also have the Win8.1 msu file but that just says the update is already installed.
I know there've been widespread Surface Pro 3 issues with the adapter dropping after sleep or after an update to Windows 10, and I had experienced those problems before, but this just sort of happened out of the blue and isn't fixable through just a reboot. If anyone can provide some guidance here, I'd really, really appreciate it.
I have no Wireless adapter showing under Control Panel → Network and Internet → Network Connections. I just see Bluetooth and Ethernet.
How do I reinstate the Wireless adapter in Windows so I can make a connection to a wireless network?
I am also missing the option to 'manually connect to a wireless network', as shown here:
It is a desktop Windows 10 machine with a Linksys AC1200 USB wireless adapter plugged in and I am trying to connect to a 4G hub.
Linksys AC1200 is present and enabled in Device Manager (reporting as Linksys WUSB6300). The drivers are the latest from the Linksys website.

I had similar situation where the network drivers and the hardware were fine (Device Manager listed all network adapters and Linux used the network just fine, but there was no network in Windows 10 and no Network Connections in network settings). My guess is that I had Cisco AnyConnect VPN installed in Windows 8.1 and then upgraded to Windows 10 where it all got messed up.Many users experienced that and there were many suggestions and none of them worked.
Eventually I had to run the following command to reset the absent network connections:
The first time it failed and gave many errors. Then I tried
netcfg -d command again and then it was successful (bizarrely). Then I rebooted and suddenly Windows 10 started picking up networks.
Now it can associate with WiFi AP securely but it still fails to get an IP address.. well, at least something.

This is a known issue with Win 10 if you have older VPN software installed like Cisco or in my case Junos. What worked for me was to uninstall the VPN and reboot. However the articles out there suggest registry editing:
Start CMD as an admin
reg delete HKCRCLSID{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f
next in the same CMD:
netcfg -v -u dni_dne

reboot and wifi should be back.
However I got the 'registry key not found so I unstalled the VPN, reboot and wifi is back. Next I installed a new version from Win 10 store and everything works great!

Go into Device Manager and see if the driver is installed under the Network Adapters category. In device manager you can also check if the driver is disabled or not. You can open Device manager by following these steps, or you can search for devmgmt.msc in the search bar from the Start Menu.
If the driver is not installed, go to the manufactures website and download it.

PS: If you want to create a wifi hotspot (when your wireless adapter is working properly), try the following command in Command Prompt

I just had the same issue. Drove me nuts. No connection options listed except Broadband and dial-up (what year is this??), with an Ethernet connection.I saw that a Windows Update had been installed this morning, about the time that the wifi crapped out. Did a system restore back to the update installation and voila---my wifi adapter was back.I knew it was something with the laptop because my tablets and phone wifi were both fine.

I have had same issues but got it resolved. Always turn off the wifi of PC/Laptop before shutdown. Whenever PC/Laptop is again started wifi adaptor will be available under network adaptor tab. Switch on Wifi and search for required wifi network.Hope this works for all.

Yesterday, between one minute and the next, the network adapter went missing from the device manager. It has shown up randomly again and vanished within 10-15 minutes. Currently it has been missing from the list for around 12-14 hours. I have turned on 'Show hidden devices' and it doesn't show up there either. I've downloaded the latest driver package from the Microsoft website and tried to manually install the drivers. The device is fully updated with all the latest updates. I plugged it in to a wired network and checked and it says the device is fully up to date.
This is what my device manager looks like for network adapters.
The following occurs when I try to install the drivers from the downloaded Surface Pro 3 driver zip package.
As you can see, despite picking the correct driver it doesn't actually show a device to install. I'm not sure if this is related to the fact that it is missing from device manager completely or not.
I've done a fully RESET on the device twice to no change at all. The screenshots above were taken directly after a full Windows 10 RESET.
I've also searched all the various posts to try and resolve it and nothing seems to line up. As shown above, I can't actually update my drivers as it won't let me pick anything.
