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 get poor download speeds, and *REALLY* poor upload speeds. I should get a steady 25/25 Mbps down/up. Instead, I get an unsteady 6-20 Mbps down, and only ~1 Mbps up. I've ruled out everything but Fedora 25 (same hardware works fine in F24 and Windows), and it's making me kinda want to go back to F24. :(
