[HELP!] 5Ghz Wifi Driver for Bootcamp Windows 7 (Macbook Pro 13" 2015)

Hi,

Thank you for your prompt response!

Yes, I get proper speeds in OSX (just checked and it's 5 times my Windows speeds from the same spot).

I tried your suggestion of verifying the original drivers but it seems like the assistant isn't properly set up? I can't proceed when I press continue and the action does not say "download and check Bootcamp..." but only "download support software". I've attached 2 screenshots below.

As for hardware, nothing has been modified.

As an aside, thank you very much for your help Loner T! I feel almost honoured lol, since out of the countless guides and forum posts I've read, I remember your name quite distinctly! I hope we can solve this annoying problem.

Tried the drivers but no dice.

Running the exes did not work and so I tried installing the .inf files manually after unzipping. Chose the ac and multiband drivers from a list for the Win7 and WinLegacy drivers respectively.

Both give me error code 10.

The settings for both drivers did, however, contain a band preference option. Is the listed setting the same as a 5 Ghz preference though?

In any event it did not work and I could find no networks.

Also, when trying to reinstall the driver that was working on 2.4Ghz before so that I could post these results, I came across one that I had been intending to try but did not work for another reason:

Anyhow, what's the next step? Below is the prompt from installing the one that was working on 2.4Ghz. Does the slight difference in the name between all these drivers mean anything (ie the emphasis on "Wireless PCIE Full Dongle Adapter" for the one that does work)?

Downloaded the package, uninstalled all Broadcom drivers (including bluetooth ones), checked for any remaining files but found none. Uninstalled the network controller from device manager and tried running the exes in the package.

Both win7 64 bit and legacy exes ran but immediately gave a prompt saying it wasn't installed correctly. Still unidentified in device manager.

Thus, I tried installing manually by forcing the infs but both gave error code 10 when I picked the 8011.n driver.

Reverted back to my system restore so I could make this post.

I tried messing around with the 5.1.5621 drivers but they gave error code 10 as well. Upon reverting back to my 802.11ac driver however, I kept the property dialog box open from the old driver.

This Frankenstein driver effect occurs and permanently changes the settings:

Wayy more options to fiddle with but not sure if it actually does something. These additional settings have been permanently incorporated even when closing and re-opening properties from device manager.

The 802.11ac driver in comparision only had around 7 options.

I've messed around with this before to similar effect but haven't noticed any significant change in speed. Are there any options in particular that I should try changing?

Aha!

The settings DO affect the card. I disabled the g/b bands and immediately disconnected from my wifi, which is no longer discoverable!

I can still, however, see my neighbour's wifi...possibly meaning there is no "a" channel on mine???

Disabling the a band or setting it to off restores my connection.

Anything I can tweak or do?

I just downloaded both Acrylic and Wireshark. Don't really know how to use either nor what I'm looking for but it seems I need a license to access Monitor Mode in Acrylic for beacon info. Still, this is what I could see.

Noticed that the max speed is quite low for some reason even though I got wayy more than those speeds in MacOs and on other devices.

I'm not sure how to use Wireshark; can you please let me know what I should be looking for? All I see is what I think is the network traffic? An ever-adding list. Not sure how to access beacon info.

Wireshark completely wrecked my computer. After restarting and resetting network settings in cmd still couldn't get any internet access.

Finally, had to use an automatic system restore (seems windows knew it would mess things up) and was able to connect.

At the start, I got the following error message before things seemed to work.

When the test did work however, speeds were abysmal and EXTREMELY unstable. I tested over and over again, getting wildly different results over the course of an hour.

Finally, I decided to look for any remaining Wireshark files to exterminate.

Uninstalled everything in the list (even though it was technically disabled by system restore), including NPCap aspects, and voila, back to my stable speeds.

Acrylic is still installed and doesn't seem to have affected anything but man did Wireshark cause so much pain and suffering. Will avoid it like the plague from now on...

Here's what I found in MacOS

What's weird is that when I first booted into MacOS and ran a speedtest, I was getting about the same but slightly worse than Windows! Also got the same socket error a couple times. Turning off the wifi and turning it back on again on my mac fixed the problem immediately and within seconds I had increased my speed about 7 times.

It was quite tricky to get up and running but I have indeed managed to install Windows 7 on my Macbook Pro 2015. I needed it specifically for some nit picky business applications (compatibility issues with Windows 10). It was a painful process but was ultimately worth it.

Model is 13 inch Retina (Early 2015).

Should I download "version 5" of the support software? I noticed the drivers only go up to 2014 and want to confirm whether such WiFi drivers had support for 5Ghz?

As stated above, my chip is BCM94360CS if that's of any help.
