Windows 10: Wifi Adapter lost the ability to connect to 5ghz network after windows update ???

This morning I woke up and find out that my pc is not connecting to any network anymore. I tried several times to reconnect the 5g network that I've been using a long time ago. But every time it just says "Can't connect to this network". My laptops and phones have no problem connecting to this 5g network Then I tried to use this adaptor to connect to a 2.4g network and it successfully connected.

I am not sure what happened, but there is a windows 10 update that installed automatically while I was sleeping: KB4571756 OS Build 19041.508.

I went into the advanced properties of my wifi adapter, I have been here before and I noticed that the properties for 5g connection have disappeared??? I am so confused on what happened...

I have lost my wifi ability. My device manager has no network adapter listed.

I have lost my wifi ability.

My device manager has no network adapter listed.

It seems I am not alone in this predicament (thanks Windows 10!).

Any suggestions gratefully received

 

My 5GHZ wifi network is no longer appearing.

I have been connected to my 5ghz wifi network for a while around two days ago it disappeared from my list of available networks but is still on my known network.

In order to fix the issue i have:

-reset my router

-uninstalled and reinstalled my network adapters drivers

I am not to knowledgeable about network issues, and i know the 5ghz wifi connection is available and works because i am using it on other devices and the connection is fine and fast.

 

5GHz WiFi network not detected in Windows 10 in Bootcamp

Hi,

Windows 10 Pro does not detect a 5GHz WiFi network.

Others in my office are using Windows 10 and they can connect to the 5GHz wifi although they have an Intel wireless adapter, mine is Broadcom.

We have one 2.4 GHz and one 5GHz wireless network setup in our office, but my Windows 10 only shows the 2.4GHz network in the list of available connections.

There is a wall between my room and the wireless routers but even if I take my laptop to the router room it still does not pick up the 5GHz network.

The 2.4GHz network works but the connection is slow unless I take my laptop to the router room.

I'm running Windows 10 on Bootcamp on my Macbook Pro.

When I boot into OSX it successfully detects and connects to the 5GHz network but when booted to Windows 10 it only picks up the 2.4GHz network. The network adapter obviously supports 5GHz as it works in OSX.

Here are my system specs:

• Macbook Pro 2012
• Intel i5 dual core 2.5GHz
• RAM 4GB
• OS X El Capitan 10.11.2
• Bootcamp Windows 10 Pro 64bit - version 15511 - OS build 10586.494
• Wireless network adapter: Airport Extreme / Broadcom 802.11n Network Adapter
• Driver version 7.35.118.40
• Driver date 24 July 2015
• Radio types supported 802.11n 802.11a 802.11g 802.11b

Can anyone help me make the 5GHz work under Windows 10?

Many thanks

Rob
