My Surface Pro 3 will not show any available wireless networks. I check the usual stuff and ran the troubleshooter. I tried updating the driver but the system says I have the latest driver. I'm not sure what to do. I did do an Internet search and I'm not the only one with this problem. Anyway, if any can help getting my WiFi to discover wireless networks please help! Here is my Windows 10 Build number info.  ( Version 1803 - OS Build 17134.590 )

    Hello RoyFender ,

    Oh! Sorry to hear about that, It's none of our intention for this to happen and definitely this is not the experience we want for you. 

    Please follow this link: Fix Wi-Fi problems in Windows 10 .

    Thanks.

    I think I am having the same problem.  For the past few days (since 2/20/19?) my Marvell Avastar controller is mostly not working.  I can occasionally connect to the network for a short time, then the connection breaks again.

    I have tried uninstalling, reinstalling, and rolling back the device driver.  Usually starts up for a very short time, then breaks again.

    I have also tried the generic help listed in the "Fix Wi-Fi problems in Windows 10", but it did not help.

    I am very suspicious of a recent windows or office 365 update...

    Please help!

    After some research I believe my problem is the Bluetooth driver/hardware. It's tires together with the Wireless Adapter. I still haven't found a fix though...

    I uninstalled a Win10 update and rebooted.  Some hours later, I got another update notification - and this time it included a Marvell driver update, too.  I installed and it has been working fine for 24hr+.   I think it is now fixed...   Eric
