Hi guys, been playing games on Steam on Windows 10 using Bootcamp on my 2015 iMac for a couple weeks now, but suddenly I am have huge issues with the internet in when booting windows. I have horrible lag in games that I never had before. No updates present in Apple Software Update and Apple Support says they can't help me. Please help me out, I've been troubleshooting all day and this is incredibly frustrating.

It says Broadcom 802.11ac Network Adaptor #2. Under Driver it says
Driver provider: Broadcom
Driver Date: 10/10/19
Driver Version: 7.77.110.0
Digital Signer: Microsoft Windows Hardware Compatibility Publisher
This version is causing issues for many Mac owners. See WiFi Driver update as well as bluetooth d… - Apple Community as an example.
If you do not have the ability to rollback, you may be able to get the driver from Apple, using BC Assistant -> Action -> Download. Check the Bootcamp.xml and verify, before you try to install the version.
What's the timeline for Microsoft fixing the defective driver they are pushing on us through Windows Update ?
Has Apple informed Microsoft, so they are aware of how many Apple customers are being impacted by this ?
Are you using a Wired network connection or Wireless?
Wireless, unfortunately. Apartment life!
Yes, it works perfectly in macOS and gets the same speeds as my Macbook Pro. I just get the drop when I boot into Windows.
I've found a solution:
Go to the Device Manger - Networkadapter - double klick Broadcom 802 - driver - choose previous driver. :)
Sadly this is not coming up for me! All the other options I can click on, but not the rollback driver one.
Under Action when loading Boot Camp Assistant in macOS, it says Download Windows Support Software. What do you mean by check the Bootcamp.xml? What do I need to look for?
Do I need to download it onto a different usb drive than I currently have Windows 10 installed on? If it is 802.11ac do I just download it on to my original USB then?
This worked! Literally thank you so much, I am so incredibly grateful for your help!
Did you ever find a solution?
It seems we are having the exact issue.
YES! THIS. 100% fixed my problem that just began a few weeks ago. Thanks!
Danke, das war’s!!
I'm having the same issue. Started out of nowhere on Friday. I think it's because of the latest windows update. See if you can recover a backup from a few days ago. That worked for me, except I'm an idiot and accidentally installed the update again and now I'm SOL.
Seems to me it's the update though. I called Apple and Microsoft, neither of which were any help. Hopefully they fix it soon.
Excellent!
Please create a Windows System Restore point, before Windows comes running to mess it up again. 😉 See https://support.microsoft.com/en-us/help/12415/windows-10-recovery-options for reference.
Wifi very slow on iMac running Windows 10 in BootCamp
