Bootcamp No WiFi under Windows 10

Windows 10 isn't even in public beta at this point. It's a "technology preview". Apple doesn't support Windows 10 in boot camp at this point.

The Windows 10 preview doesn't work with a lot of stuff at the moment.

If you really want to play with it, install it in VirtualBox or VMWare Fusion or something. At least the networking functions will work that way. Setting custom screen resolutions is still difficult if not impossible as it doesn't work with the display drivers in most virtualization packages that provide custom scaling, etc.

Please Help

In response to samjudo58

After i scan for hardware change in the device manager the error pop up and said my driver could not be install (code 28).

please let me know if there is other solution.

Note:

I upgrade my window from 8.1 to win 10

I also have scaling problem, which make all my icon become small.

This sounds really really stupid, perhaps I didn't even have this problem but I tried everything on the forums (uninstalling the network adapter, downloading new drivers from the support, hibernation/sleep, various coding)...but I clicked "multilingual Canadian english"(we spell things differently from time to time).... After 6 hours of research that is pretty darn stupid. Little did I know I should have simply stuck with the american keyboard... #makeamericagreatagain 😉

Hi there!

I am having this problem for a second time. First time, the suggested fix worked! Then my windows machine updated and now it doesn't work again.

I also can't even find the Broadcom driver... Maybe therein lies the problem?

Thanks!

Guys, Deleting and reinstalling broadcom isn't going to do a single thing unless you have a very specific type of mac. The newer macs require the "Windows" or "Apple support software" and that's what installs the drivers for these specific things. To get this go to bootcamp with you wininstall disk and uncheck everything accept install Windows support software and let it do that. Now take the drive out and start back into windows. Hit command E and look for you drive. Now go to bootcamp and run the setup file. This will install everything you need and then will restart. This will help you get where you need to go. Now if you've got that installed and still nothing works then do as they're saying below. Also if wifi seems to be slower here than on your native OS then go to devices manager and go to update the broadcom driver and navigate in that to your wininstall disk > bootcamp > Drivers > Broadcom and install the correct one.

I am having this same exact issue. I have filed a bug report with apple on this.

With the Bootcamp support software installed on a Mac book Pro 2016 15" Fully built out (2 TB ssd, 16 GB, i7 2.9 turbo to 3.8)

After bootcamp is loaded and the latest windows 10 build is installed, wifi goes in and out. Or wont connect at all.

Multiple other devices can connect. But somehow with windows 10 64 bit installed, it will not work properly.

I already tried multiple fixes, including deleting the driver then reinstalling it several times. This seems more Software driver related than Hardware related. Searching for the Broadcom driver package using the PCI/VEN hardware ID results in nothing. Trying to goto Broadcoms website they only have linux drivers available for download.

I am using the latest OSX sierra, with all of the updates, and the latest version of Bootcamp. I have also installed that latest Bootcamp support tools. What more can i do?

Why is this problem being ignored?

If you right-click on the Wireless adapter and check the drivers version, what is the current version of the driver? I will assume that the OSX side wireless works without any issues on the same SSIDs.

Right click Broadcom Netxtreme Gigabit Eithernet and uninstall it.

And under Model install Broadcom 802.11n network adapter (Broadcom)

The Netxtreme Ethernet (wired) and 802.11n(wireless) are two different adapters. Unless you re-install both drivers, your WiFi will not work. In some cases, on newer tbMBPs, disabling 802.11n/ac bands may also solve the problem, depending on your specific Wireless network configuration.

Same issue New MacBook Pro 2016 fully max.I hope you guys at Apple can fix it or simply is no reason to have new mac .

You should try running OS X once in a while. 👿.

Wireless works for a change 😝😁 and you do not have to go looking for 10 different drivers. The AMD GPU works.

I know it works,but my connection to 5G network is not working"cannot connect to network.New mac book pro I really good machine but before is launch should be also checked with boot camp capability.Since a lot of producers using mac with windows.So simply to connect to 5G network making me struggle for week already.Just to download and install my softwares.As well mac getting really hot during work on windows.Hope this gonna be fix asap .

If the 5G works properly on the OS X side, it requires changes in Registry for the Broadcom driver on the W10 side to match. You can use Device Manager and look at bands, channels, etc.. of use NetMon to capture packets.

There is no 'fix' yet. I suggest looking at the details of your OS X 5G connection and capturing settings and duplicating them on the Windows side via the Device Manager and adapter configuration. It can be very tedious.

At first, frankly I have thought “That’s stupid comment!, why does the monitor connection affect the network driver problem!”. However there was no solution I could come up with more. In addition, in Japanese apple community site, other guy said that a certain USB-C port (the guy said one port of two USB-C, back on left side) of MacBookPro affects wi-fi connection with its electrical noise because USB-C and wifi antenna are very closely located in-side structure; they mutually electrically interfere).

I am totally not sure about the true reason. But just to cope with this trouble, I believe it worth to try it. By the way, when I connect the external monitor, I use the USB-C port on right side (using USB-C > D-sub adapter).

See USB 3.0* Radio Frequency Interference Impact on 2.4GHz Wireless Devices - White Paper and Does USB 3.1 still interfere with 2.4GHz wireless? - Ars Technica OpenForum .

There are known issues with 10.12.1 and Broadcom Wireless. Does the OSX side work correctly?

Please see Re: Wifi keeps dropping in Windows 10 (BootCamp) on new tbMBP 15" as an example.

Try disabling Hyper-V. See my answer here https://discussions.apple.com/thread/7718308
