Re: Terrible F25 WiFi Performance

I've only had Fedora 25 and Windows 10 on this new HP laptop, so I can't compare to Fedora 24 to see if there's a regression. But I get ~9MB/s transfers with Windows 10, and ~3.2MB/s transfers on Fedora 25. That's a big difference. The test is done with the laptop in the same location relative to

Since I upgraded to Fedora 25, I've had terrible network performance, and I'm not sure what's causing it. Any suggestions for troubleshooting or optimization? Any known issues with the "Intel Wireless 7265D" card or the "iwlwifi" driver in F25? Everything worked great in F24, but since F25, I ge
