Update (7/9/2018): There was a new driver released on 4/20/2018 for Broadcom 802.11ac Network Adapter, version 7.35.118.83, but the Apple update is only now pushing it. Just installed it. Let's see how it goes.

Background- Network works fine, router works fine, connections is perfect when running Mac OS. I happens on every wireless network I use. I already submitted this question in the Apple StackExchange, but after some research it's leading me to believe this is a Windows 10 problem:

https://apple.stackexchange.com/questions/314210/wifi-does-not-work-on-windows-10-bootcamp-drops-in-and-out

Attempted solutions- I tried the methods suggested in these webpages (and many more):

New information- Something that seems to have helped, but did not fix the problem was unchecking "Allow computer to turn off this device to save power". Although, somehow the device still got turned off.

I've been pinging my router consistently since yesterday. I can't find any correlation between toggling options, and ping time. Sometimes it's consistently <1ms, majority of the time its between 1-5ms, with 20ms hiccups and random Request Timeouts, then sometimes it there are lags of 200ms to 3,000ms pings with extended time outs; At which point I delete the Networ Adapter driver, and reinstall. Again, I can't seem to find any rhyme or reason as to what's causing this variability in connection.

My guess is that there may be some cache or registry where information begins to build up and causes it to slow down.

Question- Is there a way to diagnose the cause of these spike in ping lag?

Update- Mac OS is also exhibiting ping lag and Request Timeouts. However, connection is seamless when streaming and browsing, with no connection drops or lags.

Previous post-

WiFi is consistently dropping at random times regardless of network.

Question : how do I fix it so I have a reliable consistent wifi connection when I use Windows 10?

I have a MacBook Pro, purchased late 2017.

WiFi will randomly disconnect when I run Windows 10. It works better on certain networks than others but it's always intermittent. Even on very robust networks it will eventually begin to drop. Once it drops it sometimes will simply not reconnect. Other times the drivers will randomly be disabled, not sure if this has to do with windows updates.

I tried manually installing and uninstalling drivers, rolling back drivers, installing and reinstalling the windows support software, and even using third party driver support software. Wifi connection still drops randomly with no perceivable pattern.

I went to the apple store and I was simply told that this is a windows issue. I had windows running on a MacBook air (2010) and never experienced these issues. It also seems they haven't come up with an update for the driver in almost two years. I ran out of ideas, any pointers on how to fix the wifi connection problem is appreciated.

Don't know if you still have this problem but I had this issue and after months I finally found a fix that worked for me. I used this random lonovo driver found here https://support.lenovo.com/us/en/downloads/ds103679 . I Found it by checking out which driver my GF was using on her older MBP on windows 10, and this one was very similar. It seems to have completely fixed this issue for me, hope it helps you as well!
