The title says it all, I updated the wifi driver to "Marvell Semiconductor, Inc. – Net – 15.68.17013.110", and after that update, I can't connect to a 5GHz wifi connection, I can only connect to 2.4 GHz. when i try to connect to the 5GHz, it says: "Unable to connect to this network". Uninstalling the wifi driver, and restarting the device did help me get the 5GHz connection back to my Surface book, but when i decided to try to install the same driver again, and try to connect to 5GHz again, the same "Unable to connect to this network" appears. Does anyone have this issue?

    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,

    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

    To be clear, you installed the beta driver 15.68.17015.112 because you could not connect to Tenda's mesh network at 5GHz with the previous .110 driver and still have this issue?

    I now have exactly the driver version installed as mentioned above. Still can't connect to 5Ghz WLAN with Surface Book 1. Connecting to Tenda Wifi MW 6. Awfull speed of 12Mbs instead of 65Mbps as my Smartphone nearby has....
