Marvell Semiconductor, Inc. – Net – 15.68.17013.110 WiFi driver breaks 5GHz connection on the Surface Book (1st Gen i5 with dGPU 256 GB)

Hi Barb,

Yes, exactly.

The problem started with the Update 1903, that installed .110 driver. Many times there was no connection possible. Reverting back to previous driver 15.68.9114.29 from 09.02.2017 temporarily solved the problem for me. But not constantly. After some time, the problem occured again. Sometimes it was again not possible to get any Wifi connection at all. Very frustating. Sometimes, connecting to the Wifi Bridge from Smartphone (Huawei Mate RS) helped. But also not every time. I also tried the "registry Workaround" mentioned here: https://support.microsoft.com/en-us/help/3120242/poor-wireless-connectivity-on-surface-devices-running-windows-10-and-u

Also tried to fix the driver to 5Ghz but then no connection possible at all. Reverted it back to "Auto".

Currently speed with 2,4GHz connection is okay with about 45 Mbps. But that may also be only 12Mbps sometimes.

Nothing is stable at all with the Wifi connection :(

Kind regards,

Chris

if you have this issue with the .112 driver, it is critical that you use the Feedback Hub app to file a problem report and include all the details of the Tenda firmware and model number. They know about the issue with .110 and the .112 released to Insiders is supposed to fix issues.

Can you triple check that device manager shows the .112 driver? Once you verify this and file the Feedback Hub report, please get a shared link from your problem report and reply with it here. I will attempt to escalate this after I have your link to your report.

Hi Barb, I am having this problem again for the 3rd time! Windows auto-updated again, after the maximum pause period for updates, and on schedule, my Wifi completely dies again... How can I possibly work this way?

Edit:

-I can't fix the issue this time..... My computer is essentially useless. No option to Roll Back Driver, and steps from previous two fixes not working now.

-Deleted Marvell Avastar driver > Ran driver pkg SurfacePro_Win10_18362_19.091.8173.0.msi  > Removed Pkg > Restarted > Ran SurfacePro_WIFI_Win10_15063_1804907_1.msi > Restarted 

-Driver Version is now: 15.68.9114.29 > Driver Status is: "This device cannot start. (Code 10)  {Operation Failed}"

What do i do now.....??? Other driver packages for SurfacePro 5 are all newer than this, and give same driver problem.

@Eddy Atinda: 

How are we supposed to install an Insider Preview, when I can't even get on the wifi?!

So we are supposed to manually roll everything back, and then subscribe to essentially be on Beta version of Windows (i.e. a less stable then official release)... so basically we'd have to deal with other potential bugs to just get our computers working normally?? This is crazy.

I keep having to switch back to my Macbook which I tried to move to a Surface from, just to get my Windows computer working... dont you think this is a little crazy...? Can you imagine why Apple users don't want to use Windows when there are constant stability issues, that render the computer useless. 

Why can't you just make it work, and stop forcing a bad update driver on us??

Im seriously just going to ditch Windows and go back to my 2012 Macbook Air. In seven years, I never had a such a stability problem with Apple.
