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

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?

    I am seeing the same issue with a total WiFi failure on all bands and channels.

    In our case the problem seems to limited to WatchGuard AP325 8.6.0-646.

    They work with WatchGuard AP120 8.6.0-646 and other APs.

    Rolling back the driver restores normal operation.

    I have the same problem with my Surface Pro 6.  Upgraded to driver 15.68.17013.110 and I couldn't get connected to my wifi either.  I tried forcing 2.4 and 5 Ghz neither worked.  I am using UniFi AC pro access points.  Rolling back to an older version got me back online.
