Recently, Microsoft released some new driver updates for several Surface devices, but some surface owners report that they are unable to connect to Wi-Fi networks using the 5GHz band after installing the update. What causes Wi-Fi connections issues? How to fix it? MiniTool has the newest information about this issue.

Surface Driver Update Triggered Wi-Fi Connection Issue

Recently, Microsoft released some Surface driver updates. However, many surface users are complaining about the new Window update. Why complaining? What happened?

On July 31, Microsoft released the firmware update for AVASTAR Wireless-AC Network Controller, aiming to improve Wi-Fi connectivity. However, some Surface users reported that they have trouble in connecting to 5Ghz Wi-Fi networks after installing the update.

A user from Reddit has shared his experience. Let’s see what he experienced.

I updated the Wi-Fi driver to "Marvell Semiconductor, Inc. – Net – 15.68.17013.110", and after that update, I can't connect to a 5GHz Wi-Fi 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?Reddit

He is not the only one who encountered the error “Unable to connect to this network” after installing the updates. There are other users reporting similar issues on the Reddit thread, Microsoft Answers and the Feedback Hub.

Some users said that they can still connect to networks using the 2.4 GHz band. While other reports online stated the Wi-Fi failed completely at both 2.4 GHz and 5 GHz.

The update included two new drivers: the "Marvell Semiconductor, Inc. – Bluetooth – 15.68.17013.110" driver for Bluetooth and the "Marvell Semiconductor, Inc. – Net – 15.68.17013.110" driver for Wi-Fi.
