Wi-fi problems with new AT&T Internet

I have resolved my Wi-Fi speed problems as best I can. It turns out the latest Broadcom drivers for Windows 10 are not good, at least not for high speed. Initially, I was getting only 30 Mbps. I did much research on the Internet, and I saw a few different websites and videos recommending switching to older drivers, a couple of which I had to download and install. I have switched between 4 versions of the drivers, and the oldest one seems to work the best. My speed tops out at about 200 Mbps, although reality might be a little less. I did a large download to test the speed and I calculated about 120 Mbps, which is at least double the speed of my old internet.

However, the same computer running Mac OS gets up to 660 Mbps with my new AT&T internet. My iPhone gets about 400 Mbps. One option for me is to run an ethernet cable to the router, which would work, although in my current setup that would not be convenient.

It was slightly helpful to turn off power saving features on the ethernet and wifi cards by selecting "maximum performance" instead.

The AT&T technical support couldn't do much other than test that the internet is working. They recommended that I do a Windows Update, which took an extraordinarily long time and didn't help. It was also recommended that I reinstall the Bootcamp software, but for some reason, the install crashes and does not finish. I tried manually copying the driver from the Bootcamp software, which helped, but I got better results by downloading and installing an older driver.

It seems odd to me that the Microsoft Windows Update installs the latest Broadcom driver that is apparently defective. This could happen with my next Windows Update and I'll have to fix this again.

Best wishes,

John Coffey
