Hey guys for those of you who still have a problem with the wifi ...this is what i did to get it working

(Solution 1)

Go to device manager....

Under network adapters

Right click Broadcom Netxtreme Gigabit Eithernet and uninstall it.

Then at the menue bar click search for hardware changes It should come back.

(Solution 2 ) worked for me!

Under other devices

Right click Network Controler and Click update driver.

Hit browse my computer for driver soft.

Let me pick from a list of dev...

Scroll down to Netword adapters

Under Manufacture... Scroll down to Broadcom.

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

Hope it works for you :)

Hello Guys!

I found a soulution to the problem.

-> go in Windows 10 to youre search bar and type -- device manager -- click on it and go to network adapters.

select broadcom and uinstall the driver. Next cick in the top window on action and scan for hardware changes.

the broadcom driver will return and your wifi problem is sloved. let me know if it doesn't work

I tried that but device manager doesn't show any network adapter. I bought a macbook air just last week and installed windows 10 (education) on it. I see only 'network controller' in device manager. On a related note, I did have problems installing Windows 10 on this macbook. After Bootcamp assistant created the windows install disk on a flash drive, the computer restarted but did not automatically go to the install disk to bbot up. I had to restart it again and hold the option key for it to do that. So I still do not get the bootcamp screen when I startup. Could my problem be related to that?

I am glad to hear you could solve the issue before you threw your Mac like Frisbee.

As I posted before,

- Although Apple states "you can use any USB-C port for any equipment or any usage. You do not need to care about the port placement order.",

- actually electrical noises from USB-C ports affects WiFi signal.

- MacOS well handles this electrical noise issue with its OS level, so you can insert any equipment into any USB-C port.

- But for Bootcamp, Apple has not offered any solution to handle this "electrical noise issue".

- So, you just follow the port placement rule for the previous MBP/MBA models which are not installed USB-C. (right side for power supply and USB, left side for monitor and USB.)

THANKS Theweirdone21! That worked for me - Solution 2! I have no idea how you figured it out - but it works.

If you figured this out by yourself, you're AWESOME! Apple should hire you! Listening, Apple?

Thanks Again - you saved me hours/days of headaches.

I can see the wifi router but it won't connect and took some time to figure out why. My workaround this persistent connectivity issue is to unplug my external monitor before connecting to the wifi router. This indicates I may have a power supply or power management issue. This issue only occurs in Bootcamp, not macOS so it's more likely a power management issue than a power supply issue. Maybe the factory fitted dedicated NVidia GeForce 750M in the high-end late 2013 15" Macbook Pro uses a lot of power when piping to a 4K external monitor via displayport. Once I'm connected to wifi in Bootcamp I can plug the monitor back in and proceed without issues.

a finall slotion for this problem

I have a similar problem, except I am using a 2008/2009 iMac (I know, ancient by now) and Windows 7. I have been using Windows 7 on this Mac with wifi for a couple years now without apparent problems, but last week my Mac wouldn't boot up (stuck in endless loading at grey screen) (Windows side did boot up and appeared fine). Long story short, the Mac drive was corrupted and I ended up having to erase my Mac HD, reinstall the OS (I stick with Snow Leopard 10.6.8 on that computer), and restore my files with a Time Machine back-up.

Now having done that the Mac side seems to be back to normal, but the Windows 7 now will not connect to the Wifi. I tried uninstalling broadcom as was suggested here and doing the hardware scan. Broadcom reappeared on the list but my wifi connection did not return. Any ideas?

I am not sure why, but I can fix with the wifi connection issue based on the suggestion of “John of Melbourne May 24, 2017 8:09 PM”

Thanks a lot John!

Before finding the solution (not substantial solution, but you can cope with this issue), I have exactly same issue with the wifi on Bootcamp on Windows10.

• Mac Book Pro 2017 (Model No. A1706),touch-bar, MacOS10 (10.12.6)
• No problem with MacOS side, and other PC or smartphone
• Not only connection failures with specific network, but also with multiple wifi network

And Even after having followed others’ and Apple community's suggestion, such as

(1) Network trouble diagnosis and shooting using with WindowsOS standard function

(2) Uninstall and re-install “Broadcom 802.11ac Network Adapter”,

(3) Re-install the Bootcamp support software,

(4) Manual setting of DNS address (using such as 8.8.8.8, 8.8.8.4 offered by Google as public DNS address), both in Windows and Mac

(5) Switch-off Thunderbolt bridge network on MacOS side

(6) Change setting of IP6 to “Link local” in MacOS side.

(7) Slam MacBookPro to the floor and dispose dust box, and wait 2days until cooling down my anger with both Apple and Windows, and even with every IT gadget… Surprisingly my MacBookPro is unbroken! (But there is a dent on the floor)

However, I had not been able to change the situation.

At that time, I found that John wrote that this troublesome situation happens only when connecting an external monitor before connecting to the wifi router.

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).

I hope what I wrote here lets many people cool down in the situation that you can not help slamming your lovely Mac to the floor even Mac is really robust.

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.

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 .

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

Do you have any unknown devices in Device Manager?

If BC drivers are not installed yet, using Boot Camp: System requirements for Microsoft Windows operating systems - Apple Support find the W8.1 64-bit drivers appropriate for your Mac year/model and test. W10 is not officially supported yet.

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.

Well, it is officially released by now and the Wifi driver still has issues. I can't connect to my WLAN (it works fine with all other devices) but with my iPhone 6 Plus as a hotspot, I have access.

And yes, Bluetooth is still missing.

And no, I do not expect any help from Apple for a Windows problem.

I will return my pretty "one interface only" new Mac Book retina 12" and close the chapter "Windows on Mac" for this life. There is more to do than trying the impossible.
