Microsoft rolled out October 2019 firmware updates for several Surface devices. These updates included battery life improvements for Surface Laptop, Surface Laptop 2, Surface Pro 4, Surface Pro 6, Surface Book 2, and Surface Pro (5th Gen).
Surface users running Windows 10 April 2018 Update or greater can download these updates on their systems. Apart from the changes aimed at improving battery life, the latest batch of updates didn’t include fixes for some major issues related to WiFi Connectivity issues in Surface Pro 6.
The bug was first introduced by some Surface users after installing August firmware updates. People started reporting on Microsoft Answers and Reddit forums that their device fails to connect 5Ghz band WiFi. This problem affected different Surface devices apart from Surface Pro 6.
Apparently, the issue was introduced by a Marvell driver update. The forum reports suggest that the bug restricts users from connecting to 5Ghz WiFi connection with the error Unable to connect to this network. Fortunately, the bug didn’t affect 2.4 GHz WiFi connections.
No Official Fix Coming Soon
This problem left Surface users in despair who spend thousands of dollars to purchase Microsoft’s flagship devices. They expected Microsoft to release a fix as a part of this month’s firmware updates. However, Microsoft didn’t release a corresponding patch to resolve the WiFi Connectivity issues this time. A Surface Pro 6 user complained about the same on the Microsoft Community forum.
“Gee, do you think Microsoft will get around to fixing the piece-of-junk wifi subsystem in the Surface 6 so that it can reconnect to a previously-authenticated connection after coming out of sleep? I was kinda sorta hoping that maybe the latest firmware update might’ve fixed it. But no joy; I still have to disconnect and reconnect to known networks after coming out of sleep. Not a big deal, I suppose…but I thought that by 2019, and version 6 of a piece of hardware, basic stuff like wireless connectivity would just work.“
It looks like Microsoft is still investigating the bug and the company has not even started testing any potential fixes in this regard. People are of the opinion that Microsoft needs to ship a Marvell WiFi driver update to resolve this problem as soon as possible.
If you are one of those who have noticed WiFi issues on your devices, all you need to do is go to the Device Manager and uninstall the latest driver update for your network adaptor.
