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.
iMac Line (2012 and Later)
Wireless, unfortunately. Apartment life!
Does the macOS side work properly on the same wireless network?
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.
In Windows Device Manager, you can see the current driver version for the wireless adapter. Can you post the current driver version?
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?
Download the software to a USB2 Flash drive. On the USB, there will be a Bootcamp.xml file. Use a Text Editor and search from Broadcom drivers and check the version for the 802.11ac driver.
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!
Well, that’s not at all clear. Rolling back the network driver cured my ills.
I was able to rollback the broadcom driver and resolve the issue. So frustrating.
Danke, das war’s!!
