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 have the exact same issue with a Surface Pro 6 on the latest drivers and W10 Pro version. After wake I have to manually turn off - on the WiFi to have a connection again. This is so far the only cumbersome fix there is and quite annoying for this product level. Hopefully it will be fixed soon or I'll manually force an older driver and turn off W10 updates for a while.
I believe there are also issues with Skype that continues to freeze when the webcam is in use after a few minutes. With hangouts/Messenger/webcam application there are no issues.

(and I keep asking what they have tested internally). -

2019-08-07T13:30:51+00:00 This is the router I'm using (the standard one from Telenet Belgium) http://www.ktech.no/CG6640E\_User\_Guide\_English.pdf
note: no issues with any of the 10 devices connected via LAN / WiFi ac 5GHz / 2.4GHz
I think I'll just install the older firmware update that was working. So far a rollback seems to often be the only quick solution for Microsoft pushed W10 and firmware updates.
